Problems solved by technology

[0011] In the traditional mini LED technology, after the mini LED backplane process is completed, it is necessary to use a steel mesh to coat white oil to improve the reflectivity of the LED. However, the white oil process does not use a mask, and the patten is rough in production, poor in accuracy, and uniform in thickness. poor sexual control

Abstract

The invention discloses a mini-LED device and a manufacturing method, the mini-LED device is divided into a binding area, a TFT area and a surface bonding area, the mini-LED device comprises a substrate, a TFT apparatus, an insulating layer, a metal reflecting film, a mini-LED chip bonded at the surface bonding area, and a transparent protective layer covering the metal reflecting film and the mini-LED chip. According to the mini-LED device and the manufacturing method provided by the invention, the insulating layer and the reflecting film are manufactured after a mini-LED backboard process is completed, and the reflecting film plays a role in reflecting mini-LED light, so that the luminous efficiency of the mini-LED device is improved.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to a mini-LED device and a manufacturing method. Background technique [0002] With the gradual rise of wearable application devices such as smart glasses and smart watches, the demand for flexible display devices in the display industry is also increasing. Organic Light Emitting Display (OLED) has the characteristics of self-illumination without backlight, thin thickness, wide viewing angle, fast response speed, etc., so it has the natural advantages of flexible display. In the face of competition from flexible OLEDs, traditional liquid crystal display technology is gradually using flexible substrates to make breakthroughs in the direction of flexibility and curved surfaces. It can be seen that the era of flexible and curved displays is coming. Moreover, organic light-emitting diodes mainly have the advantages of self-illumination, flexible screens, high luminous effici...
