Problems solved by technology

When the OLED device is not in use, there will be external light irradiated on the OLED device and can penetrate the OLED device. Even when it is working, light with a wavelength different from that of the OLED device can still pass through the OLED device, and the existing OLED devices are all It is powered by an external power supply, wasting a lot of energy

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0021] Such as figure 1 Shown is the first embodiment of the OLED display device integrating solar cells of the present invention. In this embodiment, the OLED display device mainly includes a transparent OLED display 1 , and a solar cell 2 is arranged on one side of the transparent OLED display 1 . Preferably, the transmittance of the transparent OLED display screen 1 in the visible light band is 50-95%. The electric energy output electrode of the solar cell 2 may be electrically connected to the power supply circuit of the transparent OLED display 1 , or may be connected to a storage battery (not shown in the figure).

[0022] In this embodiment, the transparent OLED display s...

Abstract

The invention discloses an OLED (Organic Light Emitting Diode) display device for integrating solar batteries. The OLED display device comprises an OLED display screen, and one side of the transparent OLED display screen is also provided with the solar batteries. As the transparent OLED display screen and the solar batteries are combined, the transparency of the OLED display screen can be fully utilized, therefore ambient light can be converted into electrical energy to be utilized or stored, and the energy source is saved. The absorption wavelength of the solar batteries and the absorption wavelength of the transparent OLED display screen are not overlapped, so that the light rays emitted by the transparent OLED display screen are prevented from being absorbed by the solar batteries, almost all the light rays emitted by a pixel region can be emitted out, therefore the electrical energy is fully utilized, and further the energy source is saved. During the working of the transparent OLED display screen, the light rays not overlapped with the absorption wavelength of the transparent OLED display screen can still reach the solar batteries to be absorbed and converted into the electrical energy, so the photovoltaic conversion efficiency is increased.

Description

technical field [0001] The invention relates to the field of organic light-emitting display technology, in particular to an OLED display device integrating solar cells. Background technique [0002] Organic electroluminescent devices (OLEDs) are actively light emitting devices. Compared with the current mainstream flat-panel display technology Thin Film Transistor Liquid Crystal Display (TFT-LCD), OLED has the advantages of high contrast, wide viewing angle, low power consumption, and thinner volume. It is expected to become the next-generation flat-panel display technology after LCD. It is one of the most concerned technologies in flat panel display technology. [0003] Due to the active light-emitting characteristics of the OLED device, the OLED device can be made transparent without affecting the display. When the OLED device is not in use, there will be external light irradiated on the OLED device and can penetrate the OLED device. Even when it is working, light with a...
