Mask plate regulating device for evaporating organic electroluminescence device

Abstract

The invention belongs to the technical field of panel display and relates to a mask plate regulating device for evaporating an organic electroluminescence device. The mask plate regulating device comprises a frame of which one end is provided with a regulating device, wherein a guide rail is arranged on an inner wall on two sides of the frame; a mask plate body is arranged in the guide rail; and the regulating device is connected with the mask plate body. The mask plate system has a novel structure; and due to the arrangement of the regulating device, the mask plate is not required to be frequently replaced in the process of evaporating and preparing the device, so that the evaporation process is easy to operate, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of flat panel display technology, and in particular relates to a mask adjusting device for vapor deposition of organic electroluminescent devices. Background technique [0002] Organic light-emitting diode or organic electroluminescent display device (Organic Light-Emitting Diode, OLED) is a display technology that has received extensive attention in the past two decades. Simple process, low production cost, flexible display and other characteristics, not only in the field of display, but also in lighting has a lot of room for development, so it is considered to be one of the flat panel display technologies with the most development potential. The full colorization of the device is an important symbol to test its market competitiveness. At present, the ways to achieve colorization mainly include vertical stacking of three primary colors, parallel arrangement of three primary colors, multi-mode microcavity structure, ...

AI Technical Summary

Problems solved by technology

[0004] (1) The high number of operations makes it difficult to control the accuracy. When preparing parallel-arranged three-primary-color devices, it is generally necessary to use three masks of red, green, and blue to make three color layer pixels, and the mask needs to be replaced three times in the middle. Template, each replacement will inevitably cause inconsistency in accuracy, resulting in a decline in the display quality of the device

[0005] (2) The operation is difficult. The existing vacuum evaporation preparation of color parallel array OLED display devices requires at least four mask replacements. In the entire preparation process, the mask replacement is basically performed by manipulators instead of manual operations. Issues such as distance and alignment of the rails with each other make replacement very difficult and take a long time

In case the mask slips off, it will ruin the experiment
