In the display field, technologies such as LCD, DLP, projection, LED and the like exist at present.

The LCD technology, the liquid crystal display screen in the tradition, has the advantages of bright color, good contrast, high brightness and the like, but also has the defects of easy breakage, limited single-screen size and physical black edge.

The DLP technology mainly utilizes a large projector and an imaging screen to perform projection imaging, but the DLP technology is high in material consumption, high in cost, high in power consumption, large in color difference, large in key volume and high in requirement on the field environment.

The projection is widely applied to the conditions of simple construction, low budget and low requirement on picture quality, but the contrast ratio is poor, the optical fiber is dazzling, and the swimming suit shields the picture, so the application range is gradually eliminated along with the improvement of the requirements of people.

The LED technology is the fastest developing technology and the most widely applied technology at present. This technique adopts small-size lamp pearl, passes through the SMD technique to the lamp pearl, and the welding relies on the lamp pearl to give out light, the formation of image principle on PCB. The LED display screen has the characteristics of high brightness, bright color, wide application and the like. However, in order to improve the brightness of the non-luminous region between the lamp beads, the brightness of the lamp beads is improved, and the surrounding brightness is increased. Therefore, the light is too dazzling, so that an observer can hardly watch the glasses for a long time, and the blue light of the eyes is particularly seriously damaged. In addition, because the lamp beads are not luminous, the brightness is extremely uneven at the positions of the lamp beads and the positions of the non-luminous positions from the perspective of an observer. Therefore, the contrast and the gray scale at this time are not well-defined, and the effect is poor when the display is very white or when the display is excessively colored.

To solve these problems of the conventional LED technology, a grid display screen is proposed.
