[0085] By dividing the pixel point light sources on the special-shaped display screen according to the first trend lines and the second trend lines, the main control unit includes: [0086] a row driver, which is used to scan pixel point light sources located on the first trend lines; [0087] a column driver, which is used to scan pixel point light sources located on the second trend lines; and [0088] a controller, which is connected with the row driver and the column driver to receive a control signal and control the row driver and the column driver to scan the pixel point light sources according to single-image data, continuous-image data or dynamic image automatic generation programmed algorithm data.

[0089] The row driver is connected to positive electrodes of all the pixel point light sources on the first trend lines; and the column driver is connected to negative electrodes of all the pixel point light sources on the second trend lines.

[0090] The pixel point light sources arranged in a non-matrix array are anchored to the nearest intersection point of the first trend lines and the second trend lines.

[0091] Specifically, a structure of a special-shaped pixel light according to an embodiment of the present invention includes: [0092] a special-shaped display screen; [0093] a LED light; and [0094] a storage unit: the storage unit includes a single-image storage unit, a continuous-image storage unit, and a storage unit of a dynamic image automatic generation programmed algorithm, is a storage medium, such as an SD card and an EPROM element, and is used to store image data; the storage unit supports an offline update, an online update, an update using upgrade boxes, an update by writing data from a USB port, a data update by real-time conversion and writing through software after connecting a computer, and an update of wireless functions; and [0095] a main control unit: the present embodiment provides corresponding main control units for an LED light and a special-shaped display screen, in which the main control unit of the LED light mainly includes a single-chip microcomputer responsible for processing signals and outputting a PWM signal to an LED driver. The main control unit of the special-shaped display screen includes a row driver, a column driver, and a controller, and mainly has an FPGA and a single-chip microcomputer as core components, in which FPGA has a model of EP4CE10E22C8N, the single-chip microcomputer has a model of STM32F103RCT6. Formed by collectively coordinating the main control unit of the LED light and the main control unit of the special-shaped display screen as one main control unit, the main control unit is a chief coordinator for the main control unit of the LED light and the main control unit of the special-shaped display screen, receives a signal from a peripheral device, processes and schedules a response from the next stage, and outputs the control signal using the DMX512 protocol when the main control unit is integrated on a console.

[0096] Specifically, a working process of controlling the row driver and the column driver by the controller is as follows. FIG. 3 shows a schematic diagram of a control model for a single pixel point light source, in which k is a row driver of an electronic switch and is connected to a positive electrode of a pixel point light source, i is a column driver of a current controller and is connected to a negative electrode of a pixel point light source, and each pixel point light source includes RGB three primary colors. The present invention achieves single-point control in a scanning manner to save the current controller. Specifically, by connecting the positive electrodes of all the light sources on the same first trend line to the same row driver, connecting the negative electrodes of all the light sources on the same second trend line to the same column driver, and using row-by-row scanning, the column driver outputs a current corresponding to the row when each row is turned on, and thus row-by-row single-point control is achieved. Conventionally, single-point control is performed on a plurality of pixel point light sources, and thus each pixel point light source requires a current controller. The present embodiment greatly saves the current controller by connecting the pixel point light sources on each row and column.

[0097] Using the structure of the special-shaped pixel light, a working process of displaying target images and videos on the special-shaped display screen is as follows. First, defining a plurality of first trend lines and second trend lines according to orientation characteristics of the pixel point light sources, the pixel point light sources falling on the intersection point of the first trend lines and the second trend lines, anchoring the pixel point light sources that do not fall on the trend lines by default to the nearest intersection point of the trend lines, and assigning specific logical names for the pixel point light sources by an order of the trend lines; secondly, acquiring the display data of the pixel point light sources corresponding to the target image that needs to be displayed, and storing the logical names of the pixel point light sources and optical parameter data into the single-image storage unit in the scanning order of the trend lines; and finally, the controller in the main control unit driving the row driver and the column driver to scan the pixel point light sources by receiving the control signal and the control instruction to cause the special-shaped display screen to display the target image. By reading or setting duration of a single-frame target image, collecting a multi-frame target image to macro data according to a certain timeline, storing the macro data into the continuous-image storage unit, and retrieving the macro data in the video unit by the main control unit, a process of displaying a video on the special-shaped display screen is achieved.

[0098] Using the structure of the special-shaped pixel light, a working process of displaying dynamic patterns on the special-shaped display screen is as follows. Firstly, assigning logical names for the pixel point light sources on the special-shaped display screen; secondly, presetting a programmed algorithm corresponding to a target dynamic pattern, and storing the programmed algorithm corresponding to the target dynamic pattern into the storage unit of the dynamic image automatic generation programmed algorithm; and finally, the controller in the main control unit driving the row driver and the column driver to scan the pixel point light sources by receiving an optical parameter input signal and invoking a program algorithm instruction so as to display the dynamic pattern. When generating spliced dynamic patterns using a plurality of special-shaped pixel light applications, it is desirable to set the relative offset coordinates for each special-shaped pixel light, and recalculate and match the spliced dynamic patterns by combining coordinate offset parameters, such as an effect of radial lines or an effect that water wave diffuses from a center to the outside.

[0099] A control method of a special-shaped pixel light according to another embodiment includes the following steps: [0100] S1, the main control unit establishing a mapping rule according to orientation characteristics of the pixel point light sources; [0101] S2, storing the mapping rule into the storage unit; and [0102] S3, receiving the optical parameter input signal and invoking target image data or video data or dynamic pattern data according to the mapping rule to scan the pixel point light sources.

[0103] Establishing the mapping rule according to orientation characteristics of the pixel point light sources includes the following steps: [0104] S11, defining a plurality of first trend lines and a plurality of second trend lines according to orientation characteristics of the pixel point light sources, wherein the plurality of first trend lines do not intersect with each other, the plurality of second trend lines do not intersect with each other, and the first trend lines intersect with the second trend line; [0105] S12, performing spatial deformation on all of the pixel point light sources on the intersection point of the first trend lines and the second trend lines to spread into a matrix distribution, straightening and spreading the plurality of first trend lines in a horizontal direction, and straightening and spreading the plurality of second trend lines in a longitudinal direction; and [0106] S13, taking the transformed matrix distributed pixel point light sources as the mapping rule for the pixel point light sources.

[0107] The control method further includes a step S10 before the step 11: [0108] S10, dividing a special-shaped display screen having regularly arranged pixel point light sources into several identical sub-regions according to a principle of similar arrangement for the pixel point light sources, and establishing the mapping rule for one of the sub-regions, in which other sub-regions have the same mapping rule as one of the sub-regions.

[0109] For a case where the trend lines are difficult to be determined according to orientation characteristics of the pixel point light sources, horizontal trend lines and longitudinal trend lines are firstly defined, and then the pixel point light sources are anchored to the nearest intersection point of the horizontal trend lines and longitudinal trend lines according to the principle of proximity.

[0110] Specifically, as shown in FIG. 4, a half of the special-shaped display screen in the first embodiment is equally divided into three sectors. The display screen is equally divided into two halves according to the characteristics of the arrangement rule of the pixel point light sources of a circular special-shaped display screen, and then each half of the display screen is equally divided into three identical sectors, namely area 1, area 2, and area 3, in which each sector includes 65 pixel point light sources, a mapping rule for area 1 sector is established, and the remaining sectors have the same mapping rule as the area 1. Specifically, the establishment of the mapping rule is described in detail using one sector in the special-shaped display screen.

A plurality of first trend lines Row and a plurality of second trend lines Column are defined according to orientation characteristics of the pixel point light sources, the plurality of first trend lines Row do not intersect with each other and the plurality of second trend lines Column do not intersect with each other, and the pixel point light sources fall on the intersection point of the first trend lines and the second trend lines. According to the first trend lines and the second trend lines, Column uses a principle of trend line orientation while Row uses principles of row intersection, proximity, and uniform distribution (the uniform distribution principle facilitates neat wiring of circuit boards), and spatial deformation is performed on the first trend lines and the second trend lines to spread into a matrix distribution and obtain a mapping rule graph as shown in FIG. 6. In FIG. 6, black blocks are pixel point light sources distributed in a regular matrix, each pixel having a unique physical name denoted as physics_name={LED, LED2, LED3 . . . }. After distribution is defined in the matrix in the above table, a logical name is generated and denoted as logic_name={R1C1, R1C2, R1C3 . . . }, which means an LED in the first row and the first column, an LED in the first row and the second column, and an LED in the first row and the third column, and the like.
