Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises an array substrate comprising a reflecting layer and a micro light emitting diode connected to the array substrate, wherein the reflecting layer is located on the side portion of the micro light-emitting diode and used for reflecting light emitted by the micro light-emitting diode towards the display face of the display panel. According to the embodiment of the invention, the light-emitting efficiency of the micro light-emitting diode can be further improved while the transfer success rate of the micro light-emitting diode is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Micro-LED (Micro Light-Emitting Diode, miniature light-emitting diode) technology, that is, LED miniaturization and matrix technology, refers to a high-density micro-sized LED array integrated on a chip. Compared with the currently used liquid crystal display devices and OLED (Organic Light-Emitting Diode, organic electroluminescent diode) display devices, it has the advantages of fast response, high color gamut, high PPI, and low energy consumption, and has become a research hotspot in future display technology. one. [0003] However, the Micro-LED light-emitting unit is a point light source, and its light emission has the characteristics of a point light source, and most of its light cannot be utilized during use, which reduces the luminous efficiency of the Micro-LED display device. At the same ti...
