Problems solved by technology

In this method, since a large-area half-etched mask is not used, the problem of deformation of the mask at high temperature is avoided, but two layers of masks need to be covered during the operation, and the operation is cumbersome; After plating, because this part is the overlapping area of ​​FMM and Open mask, there is a gap, which makes it difficult to clean the mask later.

Abstract

The invention discloses a mask plate, a display screen with a groove structure and a manufacturing method thereof. The method comprises: after the mask plate is covered on the base substrate, the base substrate is plated with an organic material ; remove the portion of the base substrate designed as a grooved area to form a display screen with a groove structure; wherein, the mask plate corresponds to the layout of the grooved area including the frame covering the grooved area A half-etched area at and a fully-etched area covering the rest of the grooved area. The application of the invention can not only reduce the bad color mixing of the display screen caused by the deformation of the mask plate, but also facilitate the cleaning of the mask plate in the later stage.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask plate, a display screen with a groove structure and a manufacturing method thereof. Background technique [0002] With the development of electronic products, especially the rapid development of mobile terminals, full-screen displays have become the mainstream of mobile terminals, and most full-screen devices use touch to realize human-machine communication between users and devices. OLED display is a display made of organic electroluminescent diodes. Because it has self-luminous organic electroluminescent diodes at the same time, it does not require a backlight, has high contrast, thin thickness, wide viewing angle, fast response speed, and can be used for flexibility. Panel, wide operating temperature range, simple structure and manufacturing process and other excellent characteristics are widely used in flat panel display technology. And AMOLED (Active-matrix organic ...
