[0061] An embodiment of the present invention provides a solar display panel. Figure 1 is a schematic diagram of the structure of a solar display panel provided according to an embodiment of the present invention, with reference to Figure 1 , solar display panels include:

[0062] A first substrate layer 1;

[0063] A pixel unit layer 2, wherein the pixel unit layer 2 is disposed on the first substrate layer 1, and the pixel unit layer 2 includes a plurality of pixel units 21;

[0064] The light-absorbing power generation layer 3 is arranged on the side of the pixel unit layer 2 away from the first substrate layer 1. The light-absorbing power generation layer 3 includes a plurality of light-absorbing power generation units 31. The vertical projection of the light-absorbing power generation unit 31 on the first substrate layer 1 does not overlap with the vertical projection of the pixel unit 21 on the first substrate layer 1.

[0065] The first substrate layer 1 can be made of materials such as glass.

[0066] Specifically, during the operation of the solar display panel or during the non-operating operation of the solar display panel, when sunlight, i.e. visible light, enters the light-absorbing power generation unit 31, each light-absorbing power generation unit 31 will generate electron-hole pairs, the generated electrons move toward the cathode, and the generated holes move toward the anode, and then the light-absorbing power generation unit 31 can generate electrical energy by absorbing visible light; similarly, the light-absorbing power generation layer 3 is arranged on the side of the pixel unit layer 2 away from the first substrate layer 1, and the pixel unit layer 2 includes a plurality of pixel units 21. During the operation of the solar display panel, each pixel unit 21 will generate a certain internal light source. When the internal light source generated by the pixel unit 21 enters the light-absorbing power generation unit 31, each light-absorbing power generation unit 31 will generate electron-hole pairs, the generated electrons move toward the cathode, and the generated holes move toward the anode, and then the light-absorbing power generation unit 31 can also generate electrical energy by absorbing the internal light source generated by the pixel unit 21.

The solar display panel provided by the embodiment of the present invention can fully utilize the external visible light and the internal light source generated by the pixel unit 21 for photoelectric conversion to charge the display device only by directly arranging the light-absorbing power generation layer 3 on the side of the pixel unit layer 2 away from the first substrate layer 1, which greatly reduces the process difficulty and thus reduces the production cost.
