A display panel and its manufacturing method, and a display device

Abstract

The invention discloses a display panel, a manufacturing method thereof, and a display device. The display panel comprises: an array substrate; a bonding layer, which is arranged on the array substrate; the bonding layer comprises a plurality of first bonding blocks arranged in an array; A plurality of second bonding blocks; a plurality of micro light-emitting diodes arranged in an array, arranged on the side of the bonding layer away from the array substrate; an electrode layer, arranged on the surface of the side of the micro-light-emitting diodes close to the array substrate, including the first an electrode and a second electrode; the first electrode is arranged in a one-to-one correspondence with the miniature light-emitting diode, and is electrically connected with the corresponding first bonding block; the second electrode is arranged in a one-to-one correspondence with the micro-light-emitting diode, and is connected with the corresponding The two bonding blocks are electrically connected; at least two second electrodes are connected to form a sub-module. The technical solutions provided by the embodiments of the present invention improve the display effect of the display panel and improve the heat dissipation efficiency of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] As the technology of micro light-emitting diodes (Micro-LEDs) continues to develop, Micro-LEDs are increasingly applied to display devices. Micro-LED display panels have the incomparable advantages of thin film transistor liquid crystal displays (TFT-LCDs) in terms of image quality and performance. For example, Micro LED has a faster response speed, higher contrast ratio, and wider viewing angle, and Mirco-LED has the characteristics of self-illumination, so it does not need a backlight, and it can be made thinner and more power-efficient than TFT LCD. [0003] However, the driving current of the Micro-LED display panel is dozens of times that of OLED. When the Micro-LED display is lit, the temperature can be as high as 80-100 degrees Celsius. Long-term high tempera...

Problems solved by technology

[0003] However, the driving current of the Micro-LED display panel is dozens of times that of the OLED. When the Micro-LED display is lit, the temperature can be as high as 80-100 degrees Celsius. Long-term high-temperature operation will seriously shorten the life of the screen; high temperature will also affect the TFT drive. The normal operation of the substrate affects the display effect
