Abstract

The invention discloses an inorganic light-emitting diode display panel and a display device. The display panel is divided into a display area and a non-display area surrounding the display area as well as comprises a first base plate, a light-emitting device layer and a light transmittance adjusting module, wherein the light-emitting device layer is arranged on one side of the first base plate; the light-emitting device layer comprises a plurality of inorganic light-emitting diodes; each inorganic light-emitting diode comprises a first electrode, a second electrode and a p-n diode electrically connected with the part between the first electrode and the second electrode; the light transmittance adjusting module comprises a third electrode, a fourth electrode and a material layer; when an electric field between the third electrode and the fourth electrode is changed, the light transmittance of the material layer is changed; the display area comprises a non-light-emitting area and a light-emitting area; the inorganic light-emitting diodes are positioned in the light-emitting area; and the light transmittance adjusting module is at least positioned in the non-light-emitting area. Through the inorganic light-emitting diode display panel and the display device, the light transmittance of the display panel can be adjusted.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to an inorganic light emitting diode display panel and a display device. Background technique [0002] Traditional inorganic light emitting diodes (Inorganic Light Emitting Diode, ILED) are usually used as backlight sources in backlight modules of liquid crystal displays. With the development of display technology and inorganic light emitting diodes, inorganic light emitting diodes are used as pixels in high-resolution display panels In, an inorganic light emitting diode display panel is realized. [0003] However, the transmittance of the transparent display panel based on inorganic light emitting diodes in the prior art cannot be adjusted, which limits the application scenarios of the transparent display panel. Contents of the invention [0004] In view of this, the present invention provides an inorganic light emitting diode display panel and a display device...
