Plastic-film-stacked LED color screen cover with part of transparent aperture in lattice distribution

Abstract

The invention belongs to the field of LED display screen, and particularly relates to a plastic-film-stacked LED color screen cover with part of transparent aperture in lattice distribution. The plastic-film-stacked LED color screen cover with part of transparent aperture in lattice distribution is characterized in that the screen cover is an entity which is stacked and adhered by n layers of transparent plastic film or plastic board of with the same size, and an inner interlayer surface of the screen cover is provided with a pattern layer; circular black-spot layers with lattice distribution are added from the (n-1)th layer to the nth layer of the screen cover. The plastic-film-stacked LED color screen cover with part of transparent aperture in lattice distribution has the advantages that after a pixel image is subjected to light filtering treatment, luminance in the circular-cone section of a color screen pixel cell is filtered out, a network black area of the color screen is lightened, the four advantages of the LED display are given full play to, and seamless and impeccable displaying of an image output by the LDE color screen is achieved. It is estimated that one day this kind of color screen which is subjected to light filtering by adding the screen cover can become a novel and personalized domestic television, and will be applicable to thousands of households.

Description

technical field [0001] The invention belongs to the field of LED display color screens, and in particular relates to an LED color screen screen cover with transparent apertures distributed in part of a plastic film laminated dot matrix. Background technique [0002] As we all know, a huge LED color screen is assembled by several smallest color screen units. The smallest color screen unit is generally a square of 32*32 pixels or a rectangle of 32*64 pixels. The main parameter of an LED color screen is the pixel cycle. The vertical or horizontal distance between pixels is called pixel period A, and the unit is mm, such as P1.8, P2, P2.5, P3, P4 distribution represents pixel period A=1.8, 2, 2.5, 3, 4 mm . The pixels of the LED color screen are distributed in a vertical and horizontal equidistant (A) distribution called a dot matrix distribution. The smaller the pixel period, the higher the resolution of the LED color screen, the better the displayed image, and the higher the...

Problems solved by technology

Such unreal, discontinuous, and flawed images will make the human body visually uncomfortable, especially not suitable for long-term viewing

Large indoor screens, such as indoor LED color screens in TV stations or theaters, need to be watched for a long time, and human vision will be very uncomfortable

This kind of technical defects, including periodic black grids, dazzling dot matrix light intensity, dark black areas on the network, too much contrast between light and dark, cannot be viewed at close range or for a long time, which is the main technical defect of current indoor LED color screens

This kind of color screen visual defect, in the final analysis, is caused by the network black area between the color screen pixels.
