LED display method, LED structure, LED display unit and an LED display device

Abstract

The present invention relates to an LED display method, an LED structure, an LED display unit and an LED display device. The LED display device comprises at least one LED display unit which comprises a first color LED, a second color LED, a third color LED and a fourth color LED with different main wavelengths. The LED display method comprises the steps of (S1) obtaining a video signal comprising multiple four-base-color full-color pixel information, wherein each four-base-color full-color pixel information comprises a first color component information, a second color component, a third color component and a fourth color component, and (S2) using the first, second, third and fourth four-base-color full-color pixel information in the multiple four-base-color full-color pixel information to drive the first color LED, the second color LED, the third color LED and the fourth color LED in a same LED display unit. According to the LED display method, the LED structure, the LED display unit and the LED display device, the display effects of true wide gamut and high perceived resolution can be achieved.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED display method, an LED structure, an LED display unit and an LED display device. Background technique [0002] As a new type of display technology, light-emitting diode display technology has gradually been accepted by the market due to its advantages of energy saving, environmental protection, and high brightness, and has been widely used in urban media, urban transportation and other fields. [0003] In order to make the images displayed by light-emitting diodes clearer and the colors more vivid and vivid, higher resolution and wider color gamut have always been the goals pursued by the light-emitting diode display industry. [0004] (1) Most of the existing LED display screens use the traditional three-primary color display technology, which can display a triangular color gamut with R, G, and B as vertices. The color gamut of the display device is wider, but it sti...

AI Technical Summary

Problems solved by technology

The four-color mechanism of RGBW is used in a few occasions, but because the color coordinates of the white primary color are within the triangular color gamut, the color performance of the display cannot be improved.

[0005] (2) For the improvement of resolution, the current light-emitting diode display industry mainly adopts the method of increasing the density and scale of the physical pixels of the display device, but the direct consequence of this method is the increase in manufacturing costs, and when the pixel density reaches a certain When the level is high, there is a bottleneck in the manufacturing process, and there are also problems in heat dissipation

In addition, there are currently some methods in the industry that rely on virtual pixels or pixel multiplexing to improve resolution; this method designs various LED arrangements and multiplexes each LED in multiple virtual pixels. Although it can realize the display of larger resolution video, it essentially blurs the image information, and there is no improvement in the real perceived resolution.

[0006] In addition, in the current light-emitting diode display industry, there is no layout scheme and display mechanism for light-emitting diodes that can combine resolution improvement and color gamut expansion to achieve a truly wide color gamut and high-perceived resolution display effect
