Description

Full visual angle chip arrangement structure and display screen

Technical Field

The utility model relates to the field of LED display, in particular to a full-view chip arrangement structure and a display screen.

Background

With the virtual shooting of XR, new shooting technologies such as naked eye 3D are mature, especially the popularization of XR virtual technologies applied to film shooting, the requirements and standards of the market on the display effect of an LED screen are higher and higher, and the standards on the color consistency of the full view angle of the screen are more and more severe. The CHIP type lamp beads used by the traditional CHIP are commonly provided with a TOP LED and a CHIP LED, the main technological processes comprise die bonding, wire bonding, packaging, testing and the like, wherein the die bonding is to place three types of red, green and blue tube cores on a bracket or a substrate, the common CHIP arrangement mode is that R, G, B types of tube cores are sequentially arranged in a 1 shape in the middle of the lamp beads, and the arrangement mode is shown in the figure 1, so that the consistency of left and right visual angles is ensured.

However, the peripheral cup wall of the lamp bead has a certain height, when the white lamp is lighted, the upper and lower visual angles of the traditional LED screen can only see the single-color chip, so that the problem of color cast to a certain extent exists, and the visual effect is affected. If the LED is orderly arranged from top to bottom in R, G, B sequences, the whole is reddish because the cup wall shields the R tube cores at the top from top to bottom, and the whole screen is bluish from bottom to top in the same way.
