[0050] In the present embodiment, a first control instruction and a second control instruction are received, and a first turn-on instruction is sent to an IC module of an LED light board connected to a test terminal according to the first control instruction, wherein the first control finger is parsed to obtain first enable data, and a first turn-on instruction is generated according to the first enable data, and the IC module of the LED light board turns on all pins according to the first turn-on instruction, so that all LED light sources connected to all pins emit light to form a light-emitting area, wherein the light-emitting area is a light-emitting area formed when all LED light boards of a display device are lit.

[0051] Step S13, according to the second control instruction, a second conduction instruction is sent to the IC module of the LED light board connected to the test terminal in sequence, so that each pin of the IC module of the LED light board is turned on in sequence, and the LED light sources connected to each of the pins emit light in sequence.

[0056] In this embodiment, the test terminal may also include a camera device, through which image information including the light-emitting area is obtained, wherein the image information includes first image information and multiple second image information. Specifically, when all pins are turned on, the first image information including the light-emitting area is captured, and the first image information includes the image information when the LED light source on the LED light board of the display device emits light, that is, the image information of the light-emitting area, and the light-emitting area is composed of all the emitting LED light sources. It is also necessary to capture the second image information including the light-emitting area when each pin is turned on, and each second image information only includes the image information of one LED light source. Further combining and analyzing the first image information and the second image information can reveal the specific situation of the light board wiring, which is convenient for subsequent testing and research and development.

[0057] Furthermore, a fourth embodiment of the method for generating wiring information of a light board of the present invention is proposed. In this embodiment, step S30 includes:

Based on the position information of each LED light source and the plurality of second image information, the position information of the corresponding LED light source in the light-emitting area when the pin is turned on can be determined. Through the present invention, the specific position of each pin of the IC module and the LED light source connected thereto in the light-emitting area of ​​the LED light board of the display device, i.e., the wiring information of the light board, can be known.

[0067] In this embodiment, the first image information is first corrected, and each pixel point information is extracted from the corrected first image information, wherein the pixel point information includes the pixel point brightness value and / or the pixel point color value. Because the photo may also contain a non-luminous area, the pixel point information of the luminous area and the non-luminous area is different, and the position information of each LED light source in the luminous area can be further determined based on each pixel point information. The luminous area and the non-luminous area can be distinguished based on the pixel point information, and the position information of each LED light source in the luminous area can be effectively determined.

[0071] Step S102: taking any LED light source in the light-emitting area as an origin, and determining coordinate information of each LED light source in the light-emitting area according to the origin.

[0072] In this embodiment, the brightness value of each pixel is extracted from the corrected first image information, the brightness value of each pixel is compared with the preset brightness value, and the pixel whose brightness value is greater than the preset brightness value is selected, and the area composed of all the pixel points whose brightness value is greater than the preset brightness value is used as the luminous area. Any LED light source in the luminous area is used as the origin. For example, the luminous area is an area surrounded by the lines connecting four corner points, and one of the corner points can be selected as the origin, and the coordinate information of each LED light source in the luminous area is determined based on the origin. The coordinate information of each LED light source in the luminous area can be determined by the image information.

[0073] Furthermore, step S51 further includes:

[0074] Step S200, extracting the color value of each pixel from the corrected first image information, and comparing the color value of each pixel with a preset color value;

[0076] Step S202: taking any LED light source in the light-emitting area as an origin, and determining coordinate information of each LED light source in the light-emitting area according to the origin.

[0077] In this embodiment, the color value of each pixel is extracted from the corrected first image information, the color value of each pixel is compared with the preset color value, and the pixel whose color value is greater than the preset color value is selected, and the area composed of all the pixel whose color value is greater than the preset color value is used as the luminous area. Any LED light source in the luminous area is used as the origin. For example, the luminous area is an area surrounded by the lines connecting four corner points, and one of the corner points can be selected as the origin, and the coordinate information of each LED light source in the luminous area is determined according to the origin. The coordinate information of each LED light source in the luminous area can be determined by the image information.

The position information of each pin and the corresponding luminous LED light source is associated to generate the routing information of the LED light board.
