Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] figure 1 Shows the arrangement of light-emitting tubes of the virtual LED display screen in the first preferred embodiment of the present invention. The display screen of the present invention is displayed in red (R), green (G), blue (B), yellow (Y), or red (R), green (G), blue (B), and cyan (C) light-emitting tubes are the display units. The four different-shaped spheres in the figure represent light-emitting tubes of four different colors, and the combination of four light-emitting tubes of different...

Abstract

The invention relates to an LED display screen. Light-emitting tube arrays are formed on the LED display screen by taking red, blue, green and yellow light-emitting tubes or red, blue, green and indigo light-emitting tubes as display units, and space between columns is twice of space between rows, or vice versa; each 2x2 light-emitting tube array comprises red, blue, green and yellow light-emitting tubes or red, blue, green and indigo light-emitting tubes, four light-emitting tubes in different colors are combined into four primary-color pixel points, and a light-emitting tube is enabled to participate in the process of imaging of eight adjacent pixel points through virtual mapping,, so that resolution ratio of the display screen is guaranteed, color gamut of the display screen is increased, 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...
