Problems solved by technology

[0002] Most of the current OLED display body uses evaporation of different OLED materials to achieve OLED patterning. This method is no problem when the pixel density is lower than 700, but when the pixel density is higher than 800, the existing manufacturing technology will enter the physical bottleneck

Embodiment Construction

[0030] In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0031] The invention provides a silicon-based micro-display screen and a preparation method thereof, which are mainly used to solve the problems that the existing OLED vapor deposition patterning technology has physical limits and high pixel density patterning is difficult.

[0032] Such as figure 1 As shown, the silicon-based micro display screen includes: a driving backplane 10, a pixel definition layer 20 formed on the driving backplane 10, a light emitting layer 21 formed in the pixel definition layer 20, and a The encapsulation layer 60 of the light emitting layer 21 and the metal reflective layer 50 formed between the light emitting layer 21 and the encapsulation layer 60 .

[0033] The driving backplane 10 includes a silicon sub...

Abstract

The invention provides a silica-based micro display screen and a preparation method thereof. The silica-based micro display screen comprises a driving backboard, a pixel definition layer formed on thedriving backboard, a light emitting layer formed in the pixel definition layer, a packaging layer for packaging the light emitting layer, and a metal reflection layer formed between the light emitting layer and the packaging layer. Compared with the prior art, the silica-based micro display screen breaks through the physical limit of high-precision metal masks with high pixel density, and is capable of realizing the display with 2000 and higher pixel density.

Description

technical field [0001] The invention relates to a silicon-based micro display screen and a preparation method thereof, belonging to the field of display panel preparation. Background technique [0002] Most of the current OLED display body uses evaporation of different OLED materials to achieve OLED patterning. This method is no problem when the pixel density is lower than 700, but when the pixel density is higher than 800, the existing manufacturing technology will enter the physical bottleneck. [0003] Therefore, realizing a colorful display with high pixel density is an urgent technical problem to be solved at present. Contents of the invention [0004] The purpose of the present invention is to provide a silicon-based micro-display and its preparation method, the preparation method can break through the physical limit of the existing vapor deposition patterning, and realize the display with high pixel density. [0005] In order to achieve the above object, the prese...
