Problems solved by technology

This structure simply encapsulates multiple pixels together, which will cause the light emitted by adjacent pixels to interfere with each other when they emit light at the same time, which will lead to color difference, insufficient contrast and sharpness of the final image. Problems such as poor display effect

Abstract

The invention provides an LED display device, a preparation method thereof and display equipment. The LED display device comprises a substrate, a plurality of pixel points arranged on the substrate, and packaging glue covering the pixel points. Each pixel point comprises at least one LED chip. The LED display device further comprises light blocking walls which are vertically arranged on the substrate in a criss-cross mode and separate every two adjacent pixel points, and the packaging glue covers the light blocking walls. According to the LED display device provided by the invention, the lightblocking wall is arranged between every two adjacent pixel points and the plurality of pixel points are isolated in pairs, so that the crosstalk phenomenon between any two adjacent pixel points can be effectively avoided, and the mutual interference between different light rays is avoided, and thus the contrast and sharpness of a finally formed image are improved, and the clearness of the image is ensured.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED display device, a preparation method thereof, and a display device using the LED display device. Background technique [0002] At present, due to the advantages of bright colors, wide dynamic range, high brightness, low power consumption, long life, impact resistance, stability and reliability, LED display screens have become the most advantageous new generation display media, and are widely used in large squares, Commercial advertisements, stadiums and other places. [0003] The LED display screen is mainly composed of multiple LED display devices assembled, and each LED display device is packaged with one or more pixels. Such as figure 1 As shown, for LED display devices packaged with multiple pixels, the existing packaging structure is generally to arrange a plurality of LED chips 200 on the substrate 100 to form the pixels, and then fabricate the substrate 100 to...
