Description

Technical Field

[0001] The present invention relates to the technical field of intelligent display control, and particularly to a grid-shaped display screen. Background Art

[0002] LED technology mainly uses small-sized lamp beads. The lamp beads are soldered on a PCB through SMD technology. Depending on the imaging principle of the lamp beads emitting light, LED display screens have the characteristics of high brightness, vivid colors, and wide applications. However, in order to increase the brightness of the non-light-emitting areas between the lamp beads, the brightness of the lamp beads themselves is increased, resulting in an increase in the surrounding brightness. This causes the light to be too dazzling, making it difficult for observers to watch for a long time and causing great harm to the human eye's blue light. In addition, since there is no light emission between the lamp beads, from the observer's perspective, the brightness of the positions of the lamp beads and the non-light-emitting positions is extremely uneven. Therefore, at this time, the contrast and gray scale are not distinct, and the effect on the picture with transitional colors is not good.
