Abstract
The present disclosure provides a display panel, a method for manufacturing the same, and a display device. The display panel includes a power supply, and includes a display area and a non-display area. A solar cell is disposed in the non-display area and is configured to convert external light into electric energy when the external light is irradiated on the solar cell, and charge the power supply with the converted electric energy.
Claims6
A method for manufacturing a display panel,
- the display panel comprising a power supply, and comprising a display area and a non-display area;
- the method comprising:
- forming a solar cell in the non-display area of the display panel, wherein the solar cell is configured to convert external light into electric energy when the external light is irradiated on the solar cell, and charge the power supply with the converted electric energy;
- wherein forming a solar cell in the non-display area comprises:
- forming an initial solar cell on a second substrate;
- patterning the initial solar cell to obtain the solar cell;
- forming sequentially a plurality of OLED devices and an encapsulation layer on a first substrate;
- and
- making the solar cell on the second substrate and the encapsulation layer on the first substrate opposite to each other, and bonding the solar cell to the encapsulation layer,
- wherein the solar cell is formed between any two adjacent OLED devices when viewed from a direction perpendicular to an extending direction of the first substrate.
A display panel comprising a power supply, and comprising a display area and a non-display area, wherein
- a solar cell is disposed in the non-display area, and the solar cell is configured to convert external light into electric energy when the external light is irradiated on the solar cell, and charge the power supply with the converted electric energy;
