Abstract

The invention provides a display panel, a preparation method thereof and a display device. The display panel comprises a display area, a non-display area surrounding the display area, a substrate extending from the display area to the non-display area, a photoresist layer which is arranged on the substrate in the display area, and a micro light emitting diode layer which is arranged on the substrate in the non-display area. According to the display panel, the preparation method thereof and the display device, the white photoresist layer is coated on the substrate, so that the brightness of themicro light emitting diode is improved; the manufacturing cost of the micro light emitting diode backlight substrate is reduced, and the production yield is improved; a thin-film transistor device can be protected; and the stability of the thin-film transistor device is improved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] There are two main applications of miniature light-emitting diodes (Mini LED) in display. One is as a self-illuminating LED display, which is similar to small-pitch LEDs. Since the package does not require gold wires, compared with small-pitch LEDs, On the same chip size, Mini LED can also be displayed with a smaller dot pitch. The other is the application in backlight. Compared with traditional backlight LED modules, Mini LED backlight modules will adopt more dense chip arrangement to reduce light mixing distance and achieve ultra-thin light source modules. In addition, with regional control, Mini LED will have better contrast and display effect. In terms of the most basic elements of display, including power consumption, cost, lifespan, dot pitch, brightness, an...
