Gridding display screen

Abstract

The invention relates to the technical field of display, and discloses a gridding display screen which comprises a substrate, a plurality of lamp beads and a gridding display cover. A grid display cover is fixedly installed at the top end of the substrate, a plurality of square frame spaces evenly distributed in a rectangular array mode are formed in the grid display cover in a penetrating mode, the four sides of the grid display cover are attached to the four sides of the substrate in the vertical direction, and the back face of the grid display cover is attached to the front face of the substrate. The multiple lamp beads are evenly installed on the front face of the base plate in a rectangular array mode, the multiple lamp beads are evenly distributed in the multiple square frame spaces, and the number of the lamp beads in each square frame space is the same. According to the invention, the lamp beads with small spacing are used as miniature projectors, then light passes through the square frame space, and imaging is carried out on the surface of the grid display cover, so that the effect of grid display is achieved; and the aim of achieving gridding display is achieved because the technology can meet the effect that the pixel filling rate is close to one hundred percent, so that the brightness of a display picture is consistent and continuous, and the color is uniform.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a gridded display screen. Background technique [0002] Currently in the display field, there are LCD, DLP, projection, LED and other technologies. [0003] LCD technology, which is the traditional liquid crystal display, has the advantages of bright colors, good contrast, and high brightness, but it is also fragile, the size of a single screen is limited, and there are physical black borders. [0004] DLP technology mainly uses large projectors and imaging screens to project images, but this technology often has high consumables, high cost, high power consumption, large color differences, large key volume, and relatively high requirements for the on-site environment. [0005] Projection is widely used in situations where the construction is simple, the budget is low, and the image quality is not high, but the contrast is poor, the optical fiber is dazzling, and the swimsuit bl...

Problems solved by technology

This causes the light to be too dazzling, making it difficult for observers to watch for a long time, and the blue light is particularly harmful to the human eye.

In addition, because there is no light between the lamp bead and the lamp bead, from the perspective of the observer, the brightness of the position of the lamp bead and the position where the light is not emitted is extremely uneven

Therefore, the contrast at this time, the gray scale is unclear, and the display is very white, or the effect is poor for the excessively colored picture.
