Problems solved by technology

[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 primary color system is limited by these three primary colors,

Embodiment 2

[0032] A four-primary-color LED display screen includes at least one LED module; the LED module consists of figure 1 Composition of the PCB board shown, the PCB board includes figure 2 The LED pixel point 6, the power supply positive line, the power supply negative line, the signal line and the driving control module of the LED pixel point are shown; image 3 The LED pixel point 6 shown is composed of a red LED light emitting diode and a green LED light emitting diode integrated packaging unit 7, a blue LED light emitting diode and a yellow LED light emitting diode integrated packaging unit 8; the red LED light emitting diode and the yellow LED light emitting diode are along the The green LED light-emitting diodes and the blue LED light-emitting diodes are arranged at intervals along the diagonal; wherein the red LED light-emitting diodes, green LED light-emitting diodes, blue LED light-emitting diodes and yellow light-emitting diodes are at least There is one; the positive ...

Embodiment 4

[0040]The fourth embodiment of the present application is the color matching method of LED light-emitting diodes when the four-primary-color LED display screen of the application embodiment 1-3 displays different white and yellow colors, and is characterized in that when the screen displays white, the blue LED light-emitting diodes are driven And the yellow LED light-emitting diode emits light; when the screen displays yellow, drive the yellow LED light-emitting diode to emit light. The experimental results show that two displays of the same size play the same video at the same time. The four-color LED display consumes more than 30% less power than the three-color LED display.

[0041] Compared with the prior art, the four-primary-color LED display screen and its color matching method according to the present invention achieve the following effects:

[0042] (1) The present invention adopts the four-primary-color technology, adding yellow Y to the traditional RGB three-primary...

Abstract

The invention discloses a four-base-color LED display screen and a color matching method thereof.The display screen comprises at least one LED module.Each LED module is composed of a PCB.Each PCB comprises an LED pixel point, a power supply positive wire, a power supply negative wire, a signal wire and a driving control module of the LED pixel point.Each LED pixel point is composed of at least one red LED, at least one green LED, at least one blue LED and at least one yellow LED, wherein the red LEDs and the yellow LEDs are arranged along diagonal lines in a spaced mode, and the green LEDs and the blue LEDs are arranged along diagonal lines in a spaced mode.The display screen has a broader color gamut, can display more colors and more real colors, and achieves the maximum energy-saving effect with the minimum power.

Description

technical field [0001] The invention belongs to the technical field of LED display, and more specifically relates to a four-primary-color LED display screen and a color matching method thereof. Background technique [0002] As the concept of low-carbon and environmentally friendly life becomes more and more popular, LED display products involve more and more markets. How to develop more energy-saving, wider color gamut and more realistic colors. It has become a market that major manufacturers and large R&D institutions compete for. [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 primary color system is limited by these three primary colors, [0004] Therefore, how to develop a ...
