a led display

Abstract

The invention provides an LED display screen. Light-emitting tube arrays are uniformly arranged on the LED display screen in a column and row equidistant manner by taking red, blue, green and yellow light-emitting tubes or red, blue, green and indigo light-emitting tubes as display units, for each 2x2 light-emitting tube array, red, blue, green and yellow light-emitting tubes or red, blue, green and indigo light-emitting tubes form a square, and four light-emitting tubes in different colors are combined into four primary-color pixel points; a light-emitting tube is enabled to participate in the process of imaging of twelve adjacent pixel points through a simple virtual mapping relationship, so that display effect is smoother, calculation burden of a control circuit cannot be increased greatly, the number of the light-emitting tubes is reduced, and manufacturing cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of image display, and more specifically relates to a four-primary-color virtual LED display screen. Background technique [0002] The display process of the LED display screen is the process of mapping the image source to the display screen, that is, there is a mapping relationship between the pixels of the display screen and the pixels of the image source. This mapping relationship can be divided into two types: real mapping and virtual mapping. [0003] Most of the existing LED display screens adopt the display method of real mapping, that is, the pixels of the display screen correspond to the pixels of the image source one by one. Such real pixels are mainly composed of the traditional red, green and blue three primary color systems. However, the color gamut of the red, green, and blue three-primary color system is limited by these three primary colors. Generally, in order to expand the color gamut of the...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems in the prior art such as the limited color gamut range of the three-primary color display screen, the large number of light-emitting tubes of the four-primary color display screen, the high cost, and the complicated virtual display mapping method, the present invention provides a four-primary color virtual LED display screen. In the case of ensuring the resolution of the display screen, the color gamut of the display screen is increased, and the manufacturing cost is reduced
