At least two first pixels 30 located in the first region 111 may be driven simultaneously by one first driving circuit 51, for example, two first pixels 30 located in the first region may be driven simultaneously by one first driving circuit 51. When one first driving circuit 51 simultaneously drives two first pixels 30 located in the first region 111, it is able to reduce the quantity of first driving circuits 51 required for the first pixels 30 located in the first region 111, thereby to reduce the space occupied by the first driving circuits 51.

When one first driving circuit 51 simultaneously drives two first pixels 30 located in the third region 113, it is able to reduce the quantity of first driving circuits 51 required for the first pixels 30 located in the third region 113, thereby to reduce the space occupied by the first driving circuit 51. The saved space may be used to accommodate other lines or devices, which is beneficial to narrowing the border of the display panel close to the third region 113.
[0070] As shown in FIG. 1c, the fourth region 114 may be located at a lower peripheral region of the display region, each first pixel 30 located at the fourth region 114 may be arranged in a corresponding pixel region 62, and the first driving circuit 51 may be connected to the first pixel 30 in the fourth region 114 through a via hole of the pixel region 62. At least two first pixels 30 located in the fourth region 114 may be driven simultaneously by one first driving circuit 51, for example, two first pixels 30 located in the fourth region 114 may be driven simultaneously by one first driving circuit 51. When one first driving circuit 51 simultaneously drives two first pixels 30 located in the fourth region 114, it is able to reduce the quantity of first driving circuits 51 required for the first pixels 30 located in the fourth region 114, thereby to reduce the space occupied by the first driving circuit 51. The saved space may be used to accommodate other lines or devices, which is beneficial to narrowing the border of the display panel close to the fourth region 114.
[0071] The display panel may have a circular shape, an elliptical shape, a polygonal shape, a shape structure with rounded corners, etc. and the display region of the display panel may have a circular shape, an elliptical shape, a polygonal shape, a shape structure with rounded corners, etc. and the display region may match the display panel in shape. In the application process, according to practical needs, at least two first pixels 30 among the first pixels 30 of at least one of the first region 111, the second region 112, the third region 113 and the fourth region 114 may be driven simultaneously by one first driving circuit 51, for example, two first pixels 30 may be driven simultaneously by one first driving circuit 51. Thus, the quantity of first driving circuits 51 required for the first pixels 30 in at least one of the first region 111, the second region 112, the third region 113 and the fourth region 114 may be reduced, the space occupied by the first driving circuits 51 is also reduced, and the saved space may be used to accommodate other lines or devices, which is advantageous for narrowing the border of the corresponding region of the display panel.
[0072] As shown in FIG. 1f, the display region 10 may include a first display region 11 and a second display region 12. The first display region 11 surrounds the periphery of the second display region 12, a plurality of first pixels 30 is arranged in the first display region 11, a plurality of second pixels 40 is arranged in the second display region 12, and a distribution density of the first pixels 30 may be the same with, or different from, a distribution density of the second pixels 40. The first pixels 30 may be evenly distributed and spaced apart from each other, and the second pixels 40 may be evenly distributed and spaced apart from each other. The distribution density of the first pixels 30 in the first display region 11 may be less than the distribution density of the second pixels 40 in the second display region 12. Since the distribution density of the first pixels 30 in the first display region 11 is less than the distribution density of the second pixels 40 in the second display region 12, the quantity of first driving circuits required for driving the first pixels 30 in the first display region 11 is reduced, the space occupied by the first driving circuits 51 is reduced, and the saved space may be used to accommodate other lines or devices, which is beneficial to increasing the area of the display region and narrowing the border of the display panel.
[0073] As shown in FIG. 1g, the distribution density of the first pixels 30 in at least one of the first region 111, the second region 112, the third region 113 and the fourth region 114 is less than the distribution density of the second pixels 40 in the second display region 12. For example, the distribution density of the first pixels 30 in the first region 111 is less than the distribution density of the second pixels 40 in the second display region 12. Since the distribution density of the first pixels 30 in the first region 111 is less than the distribution density of the second pixels 40 in the second display region 12, the quantity of the first driving circuits required for driving the first pixels 30 in the first region 111 is reduced, the space occupied by the first driving circuits 51 is reduced, and the saved space may be used to accommodate other lines or devices, which is advantageous for increasing the area of the display region and for narrowing the border of the display panel narrower.
[0074] As shown in FIG. 1g, in each of the first region 111, the second region 112, the third region 113 and the fourth region 114, the distribution density of the first pixels 30 is less than the distribution density of the second pixels 40 in the second display region 12, the brightness of the first pixels 30 is greater than the brightness of the second pixels 40 in the second display region 12, so as to reduce a brightness difference caused by the distribution density of the first pixels 30 being less than the distribution density of the second pixels 40 in the second display region 12. Therefore, the brightness difference between the first pixels 30 and the second pixels 40 with different distribution densities is not easily observed, thereby improving the display effect and improving the viewing experience of a user.
[0075] The second display region 12 may include a peripheral region and a central region, the peripheral region may surround the periphery of the central region, the peripheral region is located between the first display region 11 and the central region, and distribution densities of the second pixels 40 in the peripheral region and the central region may be the same or different. For example, the distribution densities of the second pixels 40 in the peripheral region and the central region may be different, the distribution density of the second pixels 40 in the peripheral region may be less than the distribution density of the second pixels 40 in the central region, and the distribution density of the first pixels 30 in at least one of the first region 111, the second region 112, the third region 113 and the fourth region 114 is less than the distribution density of the second pixels 40 in the peripheral region. For example, the distribution density of the first pixels 30 in the first region 111 is less than the distribution density of the second pixels 40 in the peripheral region. The peripheral region may serve as a transition region, and the brightness difference caused by the distribution density of the first pixels 30 in the first display region 11 being less than the distribution density of the second pixels 40 in the second display region 12 may not easily observed through the second pixels 40 in the peripheral region, thereby improving the display effect and improving the viewing experience of the user.
[0076] The central region may be a circular-shaped display region, an elliptical-shaped display region, a polygonal-shaped display region, and a display region with rounded corners. The peripheral region may be ring-shaped, frame-shaped, arc-shaped or strip-shaped. Specific shapes of the peripheral region and the central region may be determined according to actual needs, and shapes and sizes of the peripheral region and the central region may be matched according to practical applications.
[0077] One first driving circuit 51 may drive at least two first pixels 30 simultaneously, one second driving circuit 52 may drive one or more second pixels 40, e.g., one first driving circuit 51 may drive two first pixels 30 simultaneously, each second driving circuit 52 may drive one second pixel 40. At least two first pixels 30 may be driven simultaneously by one first driving circuit 51, at least part of the first driving circuit 51 may be located in the second display region 12, and at least part of the first driving circuit 51 may be located in the peripheral region or the central region of the second display region 12, so as to reduce the space occupied by the first driving circuit 51 in the first display region 11. Hence, the saved space may be used to accommodate other lines or devices, which is beneficial to increasing the area of the display region and narrowing the border of the display panel.
[0078] In the display panel of the embodiments of the present disclosure, the display region 10 includes the first driving circuit 51 configured to drive the first pixel 30 and the second driving circuit 52 configured to drive the second pixel 40, one first driving circuit 51 is used to drive at least two first pixels 30 simultaneously. In the first display region 11, one first driving circuit 51 is used to simultaneously drive at least two first pixels 30, so it is able to reduce the quantity of the first driving circuits, thereby to reduce the space occupied by the first driving circuits. Hence, a part of the space may be saved in the peripheral region, and some other traces may be arranged in the saved space, so that the border of the display panel may be narrower, thereby to increase the area of the display region, improve the screen-to-body ratio, meet the requirement on the narrow border of the display product, and improve the user experience.
[0079] In some embodiments, when one first driving circuit 51 is used to drive two first pixels 30 in two columns simultaneously, it may reduce the difference in gray scale, thereby to avoid the occurrence of serrated display in the periphery and provide more uniform display. One first driving circuit 51 is configured to simultaneously drive two first pixels 30 in two columns respectively, and the two first pixels 30 in the two columns respectively may be in two adjacent columns respectively, such as a first column and a second column. The two first pixels 30 in the two columns respectively may be in two non-adjacent columns respectively, for example, the two first pixels 30 in the two columns respectively may be in the first column and the third column, or the two first pixels 30 in the two columns respectively may be in the first column and the fourth column. One first driving circuit 51 drives the two first pixels 30 in the two columns simultaneously, so as to facilitate the connection, which is beneficial to reducing the length of each of the lines through which the first driving circuit 51 is connected to the two first pixels 30. The first pixels 30 may be arranged in an array form, one first driving circuit 51 may simultaneously drive two first pixels 30 in two columns respectively. The two first pixels 30 in two columns respectively driven simultaneously by the same first driving circuit 51 may be located in a same row, so as to provide a relatively small length difference between the lines through which the first driving circuit 51 is connected to two first pixels 30, thereby to further reduce the length of each of the lines through which the first driving circuit 51 is connected to two first pixels 30. One first driving circuit 51 is configured to simultaneously drive two first pixels 30 in two adjacent columns respectively, and the first pixels 30 may be arranged in an array form. When one first driving circuit 51 simultaneously drives two first pixels 30 in two columns respectively, two first pixels 30 in two columns respectively which are driven at the same time by the same first driving circuit 51 may be located in the same row, it is able to provide a relatively small length difference between the lines through which the first driving circuit 51 is connected to two first pixels 30, thereby to further reduce the length of each of the lines through which the first driving circuit 51 is connected to two first pixels 30, and facilitating the connection between the first driving circuit 51 and the first pixels 30. In addition, it is also able to reduce the space occupied by the lines through which the first driving circuit 51 is connected to two first pixels 30, and the saved space may be used to accommodate other lines or devices, which is beneficial to narrowing the border of the display panel.
[0080] In other embodiments, at least a portion of the first driving circuit 51 is disposed in the second display region 12, for example, a portion of the first driving circuit 51 may be disposed in the second display region 12. The first driving circuit 51 may be arranged entirely in the second display region 12, so that the first display region 11 has an anode and an opening for the pixel to emit light, without the first driving circuit 51. Providing at least part of the first driving circuit 51 in the second display region 12 is advantageous for saving the space occupied by the first driving circuit 51 in the first display region 11 and for making the border narrower. For example, one first driving circuit 51 may drive at least two first pixels 30 at the same time, one second driving circuit 52 may drive one or more second pixels 40, at least two first pixels 30 may be driven at the same time via one first driving circuit 51, at least part of the first driving circuit 51 may be located in the peripheral region or the central region of the second display region 12, the space occupied by the first driving circuit 51 in the first display region 11 is reduced, and the saved space may be used to accommodate other lines or devices, which is beneficial to increasing the area of the display region and for making the border of the display panel narrower.
[0081] Optionally, the display panel further includes: connection lines 60, each connection line 60 is connected to the electrodes of at least two first pixels 30, and each first driving circuit 51 is electrically connected to a corresponding connection line 60. The connection line 60 may be a metal line, and the material of the metal line may include at least one of aluminum, copper, molybdenum, titanium or silver. For example, the material of the metal line may include molybdenum or silver, allowing the metal line to have a higher conductivity and reducing losses. The connection line 60 may be a separate line, and the connection line 60 may be arranged at a same layer as a gate electrode, or may be located above or below the gate electrode layer, which may be determined according to practical needs. The connection line 60 may be arranged above or below an anode layer; the material of the connection line 60 may be the same with or different from the material of the anode layer. For example, the material of the connection line 60 may be the same as the material of the anode layer, with both the material of the connection line 60 and the material of the anode layer being indium tin oxide (ITO), which has a better light transmittance. Using the same material facilitates processing and manufacturing, simplifying the process. The connection line 60 may serve as the anode layer, and there is no need to separately form the connection line 60, further simplifying the process. The anode layer serve as a light transmitting material layer, for example, the anode layer may be an indium tin oxide (ITO) layer, which may improve light transmittance and reduce power consumption. For example, each connection line 60 is connected to the electrodes of two first pixels 30, and each first driving circuit 51 is electrically connected to a corresponding connection line 60. Each connection line 60 is connected to the electrodes of two first pixels 30 in two adjacent columns respectively, and two first pixels 30 in two adjacent columns respectively connected to the same connection line 60 may be located in the same row, which is beneficial to reducing the length of the connection line 60 and reducing the space occupation.
[0082] Optionally, each connection line 60 is connected to two adjacent first pixels 30, for example, the two adjacent first pixels 30 connected to each connection line 60 may be located in the same row or the same column, which is beneficial to reducing the length of the connection line 60, reducing the occupation of space, and saved space may be used to accommodate other lines or devices, which is advantageous in making the border of the display panel narrower.

Hence, it is able for the same first driving circuit 51 to drive the second sub-pixels 32 of the two first pixels 30 at the same time, which is advantageous to saving the space occupied by the first driving circuit 51 in the first display region 11 and facilitating a narrower border.

Hence, it is able for the same first driving circuit 51 to drive the third sub-pixels 33 of the two first pixels 30 at the same time, which is advantageous to saving the space occupied by the first driving circuit 51 in the first display region 11 and facilitating a narrower border.
[0086] During the application, the first pixels 30 may be in a Delta arrangement, an S-like arrangement, a 2 in 1 arrangement, or any other arrangements such as GGRB or blue Diamond, which may be selected according to actual needs. The connection manner in which one first driving circuit 51 drives two or more first pixels 30 at the same time for different arrangements may be determined according to practical applications.
[0087] In some embodiments, the first pixel 30 includes: a first electrode, a light-emitting unit and a second electrode laminated one on another, the first electrode may be an anode and the second electrode may be a cathode, alternatively, the first electrode may be a cathode, the second electrode may be an anode. One first driving circuit 51 is configured to connect the electrodes in at least two first pixels 30, one first driving circuit 51 may apply electrical signals for the electrodes in at least two first pixels 30 at the same time, and the light-emitting unit may be driven to emit light via the first electrode and the second electrode. The first driving circuit 51 may include a first active layer, a first source electrode and a first drain electrode connected to the first active layer, and a first gate electrode, where the first source electrode and the first drain electrode may be electrically connected to the electrodes of the first pixel 30, for example, the first source electrode may be electrically connected to the first electrode, the first drain electrode may be electrically connected to the second electrode, and the first pixel 30 may be controlled to be turned on or off by the first driving circuit 51.

[0089] As shown in FIGS. 2 and 3, each connection line 60 is connected to two adjacent first pixels 30, and each connection line 60 is connected to the two adjacent first pixels 30 through via holes of the pixel regions 62. For example, as shown in FIG. 3, with regard to a pixel region 62 of a first row located at the top or a middle row located at the middle, a first column is located at the far left side, and one connection line 60 is connected to first sub-pixels 31 of two adjacent first pixels 30 through via holes of the pixel regions 62, so as to drive the first sub-pixels 31 in the first column and the fourth column at the left side at the same time. Another one connection line 60 is connected to second sub-pixels 32 in the two adjacent first pixels 30 through via holes of the pixel regions 62 so as to drive the second sub-pixels 32 in the second column and the fifth column on the left side at the same time. Still another one connection line 60 is connected to third sub-pixels 33 of two adjacent first pixels 30 through via holes of the pixel regions 62, so as to drive the third sub-pixels 33 of the third column and the sixth column at the left side simultaneously. For the conventional Delta arrangement, the space for compressing one pixel in the border may narrow the border by about 70 m-90 m, and this space may accommodate other lines, branching units or devices, etc. thereby to facilitate the narrow border. As shown in FIG. 3, the first electrode 301 may be an anode, and the first electrode 301 may be in a normal anode arrangement. In a pixel region at the edge, there are only the anode and the opening for the pixel to emit light, with no pixel driving circuit below. This may be applied to a display panel with a circular shape or with rounded corners, so that the panel may have a narrow border.
[0090] As shown in FIG. 7, the leftmost pixel regions 62 are in a first column, one connection line 60 is connected to a sub-pixel of the first pixel 30 in the pixel region 62 of the first column and a sub-pixel of the first pixel 30 in the pixel region 62 of the fourth column through via holes of the pixel regions 62, so as to simultaneously drive the first sub-pixel of the first pixel 30 in the first column on the left side and the fourth column. Another one connection line 60 is connected to a sub-pixel of the first pixel 30 in the pixel region 62 of the second column and a sub-pixel of the first pixel 30 in the pixel region 62 of the fifth column through via holes of the pixel regions 62, so as to simultaneously drive a second sub-pixels of the first pixel 30 in the second column and the fifth column on the left side. Still another one connection line 60 is connected to a sub-pixel of the first pixel 30 in the pixel region 62 of the third column and a sub-pixel of the first pixel 30 in the pixel region 62 of the sixth column through via holes of the pixel regions 62, so as to simultaneously drive third sub-pixels of the first pixel 30 in the third column and the sixth column on the left side. It is able to compress the space of two pixels in the border, in the pixel region at the left edge, there are only the anode and the opening for the pixel to emit light, with no pixel driving circuit below, which may be applied to a rectangular display panel, allowing the panel to have a narrow border. To avoid excessive length of the connection line 60, there may be one, two or three sub-pixels between two sub-pixels connected by the same connection line 60.
[0091] As shown in FIGS. 4 and 5, each connection line 60 is connected to two first pixels 30, and each connection line 60 is connected to two first pixels 30 adjacent to each other through via holes of the pixel regions 62. For example, as shown in FIG. 4, with regard to pixel regions 62 located in a middle row, the leftmost is a first column, one connection line 60 is connected to first sub-pixels 31 of two adjacent first pixels 30 through via holes of the pixel regions 62, e.g., the first sub-pixels 31 in a first column and a fourth column on the left side, a track located at the position of the first sub-pixel 31 in the seventh column may be connected to one first driving circuit 51, the connection line 60 is not electrically connected to the first sub-pixel 31 located in the seventh column, and the first driving circuit 51 is connected to the connection line 60 via the track, thereby driving the first sub-pixels 31 in the first column and the fourth column on the left side at the same time. Another one connection line 60 is connected to the second sub-pixels 32 in two adjacent first pixels 30 through via holes of the pixel regions 62, e.g., the second sub-pixels 32 in the second column and the fifth column on the left side, so as to drive the second sub-pixels 32 in the second left column and the fifth column at the same time via the same first driving circuit 51. Still another one connection line 60 is connected to third sub-pixels 33 of two adjacent first pixels 30 through via holes of the pixel regions 62, e.g., the third sub-pixels 33 in the third column and the sixth column on the left side, so as to drive the third sub-pixels 33 in the third column and the sixth column on the left side simultaneously via the same first driving circuit 51. With the above-mentioned arrangement, it is able to compress and obtain the spatial region of two pixels in the border, so that the border may be narrowed by about 140 m-180 m, and this space may accommodate more units and lines, thereby to achieve an ultra-narrow border. As shown in FIG. 5, the first electrode 301 may be an anode, and the first electrode 301 may be in a normal anode arrangement, and in two pixel regions at the edge, there are only the anode and the opening for the pixel to emit light, with no pixel driving circuit below. With regard to the narrowing of the left and right borders, when two pixels are driven by one first driving circuit 51 in the left and right borders, the space in an underlying pad region also benefits. This is mainly because corners of the underlying pad shrink towards the display region, allowing the lines to shrink upwards and towards inside of the display region, which is beneficial to the narrowing of the lower border.
[0092] Optionally, the display panel further includes: a detection circuit configured to detect brightness of a pixel, at least part of the detection circuit is located in the first display region 11, for example, part of the detection circuit is located in the first display region 11, or the detection circuit is entirely located in the first display region 11. At least part of the detection circuit may be located in the space saved in the first display region 11 due to the first driving circuit 51, at least part of the detection circuit may overlap the first pixel 30, and at least part of the detection circuit may be located below the first pixel 30. The detection circuit may be placed in the first display region 11, so that the detection circuit is closer to the display region, which is beneficial to save the space occupied by the detection circuit in a corresponding region of the frame body, thereby to provide a narrower border.
[0093] Optionally, as shown in FIG. 6, the display panel further includes: a branching unit 61, the first driving circuit 51 and the first pixel 30 are electrically connected via the branching unit 61, so as to facilitate the electrical connection between the first driving circuit 51 and the first pixel 30, and different branching lines in the branching unit 61 may connect different first pixels 30. The first driving circuit 51 is electrically connected to the first pixels 30 via the branching unit 61, the first pixels 30 are electrically connected to the branching unit 61 via the connection lines 60, each connection line 60 may be connected to two adjacent first pixels 30, and each branching line in the branching unit 61 may be connected to two adjacent first pixels 30, thereby facilitating the arrangement of lines while facilitating the reduction of space occupation.
[0094] Optionally, at least part of the branching unit 61 is located in the first display region 11, for example, a part of the branching unit 61 may be located in the first display region 11, the space saved by the first driving circuit 51 in the first display region 11 may be used to accommodate the branching unit 61, and the space occupied by the branching unit 61 in a corresponding region of the frame body may be reduced, thereby to provide a narrower border.
[0095] Optionally, the first display region 11 includes a first region 111, a second region 112, a third region 113 and a fourth region 114, the first region 111, the second region 112, the third region 113 and the fourth region 114 are distributed along the periphery of the second display region 12, and the first pixels are arranged in at least one of the first region 111, the second region 112, the third region 113 and the fourth region 114. When closing to the region where the first pixels 30 are distributed, it is advantageous to making the border narrower.
[0096] Optionally, a distribution density of the first pixels 30 in the first display region 11 is less than a distribution density of the second pixels 40 in the second display region 12. Since the distribution density of the first pixels 30 in the first display region 11 is less than the distribution density of the second pixels 40 in the second display region 12, the quantity of the first driving circuits required for driving the first pixels 30 in the first display region 11 is reduced, the space occupied by the first driving circuits 51 is reduced, and the saved space may be used to accommodate other lines or devices, which is beneficial to increasing the area of the display region and narrowing the border of the display panel.

The frame body may be arranged in a border region 21 of the non-display region 20, and the border region 21 may surround the periphery of the first display region 11. Since the space saved by the first driving circuit 51 in the first display region 11 may be used to accommodate other lines or devices, it is able to reduce the space occupation for the non-display region 20 and make the frame body narrower.
