Embodiment 1

[0021] see Figure 12 As shown, this embodiment provides an OLED display substrate integrating solar cells, including a plurality of pixel areas, each pixel area includes an OLED display function layer, and the display substrate also includes:

[0022] The optical film layer 20 is used to gather light;

[0023] For the solar cell, the light is irradiated on the photosensitive area of ​​the solar cell after being converged by the optical film layer 10 , and the OLED display function layer is insulated from the solar cell.

[0024] The solar cell includes a back electrode 2, a photoelectric conversion layer 3 and a top electrode 5. The photoelectric conversion layer 3 is the photosensitive area of ​​the solar cell for absorbing light and realizing photoelectric conversion. The photogenerated current is extracted through the back electrode 2 and the top electrode 5. The OLED display functional layer includes various functional layers of the OLED, and each functional layer of the...

Embodiment 2

[0076] A display device in this embodiment includes a power supply circuit, and further includes the OLED display substrate in Embodiment 1, and the solar cell is electrically connected to the power supply circuit for supplying power to the power supply circuit.

[0077] The power supply circuit can not only be used to drive the OLED to emit light, but also can supply power to other devices.

[0078] The display device may be an OLED display panel, or an OLED display.

Abstract

The invention relates to the display technical field, and discloses an OLED display substrate and display apparatus integrated with a solar cell. An OLED display device provided by the invention is powered by the solar cell, so that the OLED display device has the advantages of energy saving, greenness and environmental protection, and the like; in addition, an optical film layer is adopted to converge light rays to illuminate a light-sensitive region, so that the photoelectric conversion efficiency of the solar cell is improved; in addition, the surface temperature of the solar cell is not changed obviously; and the service life of the solar cell is not affected.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display substrate and a display device integrating solar cells. Background technique [0002] In recent years, organic light emitting diode (OLED) display devices have become very popular emerging flat-panel display products at home and abroad, because OLED display devices have all solid state, self-illumination, wide viewing angle, wide color gamut, and fast response speed. , high luminous efficiency, high brightness, high contrast, ultra-thin and ultra-light, low power consumption, wide operating temperature range, large-size and flexible panels and simple manufacturing process, etc., can realize flexible display in the true sense. It is a technology that can best meet people's requirements for future displays. [0003] OLED display devices can be classified into passive OLED (PMOLED) display devices and active OLED (AMOLED) display devices according to driving types....
