DETAILED DESCRIPTION
(11) In order to make the purpose, technical solutions and advantages of the disclosure in a more clear manner, the disclosure will be further described in detail below in conjunction with the drawings. Obviously, the following embodiments relate to a part of, rather than all of, the embodiments of the present disclosure. The shapes and sizes of the various components in the drawings do not reflect true proportions, but are merely intended to illustrate the present disclosure. Based on these embodiments, a person skilled in the art may, without any creative effort, obtain the other embodiments, which also fall within the scope of the present disclosure.
(12) In the related art, in order to realize the narrow frame of the display device and the maximum screen ratio of the screen, the flexible circuit board FPC, the driving chip IC and other components are bent to the back of the display panel by pad bending process.
(13) After the pad bending process, the product generates significant heat when the driver IC works in a reliable environment or other harsh environments (such as high temperature and high humidity), and the pixels of the OLED display panel generate heat during operation, so during a certain period of time, there is more heat accumulated in the bending area BB, resulting in the temperature in the bending area BB to rise faster. However, the structure and material of the gasket used in the existing bending zone BB are not conducive to the heat emission and conduction. As shown in
(14) In view of this, the embodiments of the present disclosure provide a gasket for a display device and a display device, which are used to solve the problem that the gasket in the prior art is not conducive to heat dissipation and conduction, resulting in poor display of the display panel.
(15) Specifically, an embodiment of the present disclosure provides a gasket for a display device. As shown in
(16) The embodiments of the present disclosure can produce the following beneficial technical effects: by arranging the body of the gasket used for the display device to have a plurality of via hole structures, the via hole structures is conducive to heat dissipation and conduction, so that there will be no poor display in the display panel area corresponding to the gasket.
(17) In the above gasket according to the embodiment of the present disclosure, as shown in
(18) When the gasket according to the embodiment of the present disclosure is applied to a narrow frame display device, the narrow frame display device needs to bend the flexible circuit board FPC, driving chip IC and other components to the back of the display panel. In order to avoid physical breakage of the display panel or damage to the internal signal lines due to too small bending angle during bending, it is necessary to use gaskets as structural support in the bending area, and the shape of the bending area is generally an arc-shaped structure. Since the structure of the second portion B of the body 11 of the gasket is configured as an arc-shaped structure in the present disclosure, the second portion B of the arc-shaped structure may be formed in the arc-shaped area of the bending area. By reasonably setting the size of the gasket, the bending structure can be bent along the second portion B when bending, so that the second portion completely fills the arc-shaped area, which can further prevent the display panel from being physically broken or the internal signal line from being damaged when the angle is too small.
(19) It should be noted that both the first portion A and the second portion B of the body 11 may have via hole structures 01. For illustrative purposes,
(20) Optionally, in order to expedite the heat dissipation and conduction in the area corresponding to the gasket, in the above gasket according to the embodiment of the present disclosure, as shown in
(21) Optionally, in the above gasket according to an embodiment of the present disclosure, the cross-sectional shape of the via hole structures may a polygon or a circle. For example, the cross-sectional shape of the via hole structures may be a triangle, a square, or a hexagon. As shown in
(22) Optionally, as shown in
(23) Optionally, a material of the body 11 includes polyterephthalic acid plastic.
(24) Optionally, in order to further accelerate the heat dissipation and conduction in the area corresponding to the gasket, the material constituting the body further may include a material having better thermal conductivity than the polyterephthalic acid plastic.
(25) The thermal conductivity of PET material is 0.2 W/m.Math.K, the thermal conductivity of carbon fiber material is in a range from 400 to 700 W/m.Math.K, and the thermal conductivity of graphite material is 135 W/m.Math.K. Therefore, in the above gasket according to the embodiment of the present disclosure, the material having better thermal conductivity than the polyterephthalic acid plastic may include graphite, carbon fiber, or a combination of graphite and carbon fiber. That is, graphite, carbon fiber or a combination of graphite and carbon fiber having good thermal conductivity can be added as a gasket material to the polyterephthalic acid plastic. Moreover, graphite and carbon fiber itself have high heat resistance and good mechanical properties, so the gasket made of the above mixed material can quickly dissipate and conduct the heat of the area corresponding to the gasket, and reduce the problem of poor display in the display panel area corresponding to the gasket.
(26) Based on the same inventive concept, an embodiment of the present disclosure also provides a display device, as shown in
(27) Optionally, as shown in
(28) Optionally, as shown in
(29) Optionally, as shown in
(30) The extending direction of the via hole structures 01 is not limited to the above two manner, and may have a certain inclination angle with respect to the display surface of the display panel. As long as the body 11 of the gasket has the via hole structures 01, it belongs to the protection scope of the present disclosure, and the examples thereof are not given here.
(31) The above display device according to the embodiment of the present disclosure may be a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, or any product or component having a display function. The other indispensable components of the display device are understood and possessed by a person skill in the art, and thus are not repeated herein, nor should be used as a limitation to the present disclosure.
(32) In the above gasket for a display device and the display device according to the embodiments of the present disclosure, by arranging the body of the gasket to have a plurality of via hole structures, the via hole structures is conducive to heat dissipation and conduction, so that there will be no poor display in the display panel area corresponding to the gasket.
(33) It will be apparent to those skilled in the art that various modifications and changes can be made in the present disclosure without departing from the spirit and scope of the disclosure. Therefore, if such modifications and variations of the present disclosure belong to the scope of the appended claims and equivalents thereof herein, the present disclosure is intended to cover these modifications and variations.
