Problems solved by technology

In the prior art, most researchers are devoted to the research of transparent solar cells, but transparent solar cells only absorb infrared or ultraviolet rays, and the photoelectric conversion efficiency is low; while relatively mature solar cells have high photoelectric conversion efficiency, but due to their Completely opaque and cannot be used in common display devices

Embodiment Construction

[0026] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a display module and a display device, and relates to the technical field of display. The display module comprises a substrate; a transparent display panel which comprises a first transparent substrate, a second transparent substrate and a liquid crystal layer, and the liquid crystal layer is located between the first transparent substrate and the second transparent substrate; a solar cell panel which is located on the side, close to the underlayer substrate, of the first transparent substrate and used for supplying power to the transparent display panel; the solar cellpanel comprises a first electrode layer, a photoelectric conversion layer and a second electrode layer. The photoelectric conversion layer is located between the first electrode layer and the secondelectrode layer. The solar cell panel is located in display area. According to the display module, the solar cell panel is arranged below the transparent display panel; the solar cell panel is arranged in the display area, so that sunlight can irradiate the solar cell panel, the solar cell panel is located in the display area, the light energy receiving area on the solar cell panel is large enough, more sunlight can be received, the photoelectric conversion efficiency can be improved, and self-sufficient power supply of the display module can be better achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display module and a display device. Background technique [0002] With the development of technology, there are more and more portable devices with displays, but for the convenience of carrying, portable devices are usually small in size, resulting in small batteries, and the battery capacity is not enough to support the portable devices with displays for a long time Use, need often to be provided with the portable device charging of display, like this, then need carry charging device simultaneously, cause inconvenience for going out. [0003] In view of the above problems, technicians have installed solar cells in the display device, and the solar cells absorb the light source and convert it into electrical energy to power the display device. In the prior art, most researchers are devoted to the research of transparent solar cells, but transparent solar cells onl...
