AI Technical Summary

Technical Problem

In high-resolution display devices, especially head-mounted displays, the dense pixel spacing makes it difficult to form a black matrix between multiple pixels, leading to color mixing problems between adjacent pixels.

Method used

Multiple sub-pixels are provided in the display device. Each sub-pixel includes a first electrode, a fence surrounding the electrode, a light-emitting layer, a second electrode, and a color filter. The color filter includes first and second filters spaced apart from the second electrode at different distances. The second filter is disposed on the lower surface of the first filter to surround its edge, and the encapsulation layer is configured to surround the second filter to avoid the use of a black matrix.

Benefits of technology

It effectively prevents color mixing between adjacent sub-pixels, improves the color purity and light emission efficiency of the display device, simplifies the manufacturing process, and reduces processing time.

Abstract

提供了一种可以防止发生相邻子像素的混色的显示装置。显示装置包括设置有多个子像素的基板、设置在基板上的每个子像素中的第一电极、为每个子像素设置的围绕第一电极的边缘的栅栏、设置在第一电极和栅栏上的发光层、设置在发光层上的第二电极、以及设置在第二电极上的每个子像素中的滤色器,其中,滤色器包括与第二电极间隔开第一距离的第一滤光器,以及与第二电极间隔开比第一距离短的第二距离的第二滤光器,并且第二滤光器可以设置在第一滤光器的下表面以围绕第一滤光器的边缘。
