Therefore, according to the original ratio, it is obvious that the brightness advantage of blue cannot be brought into play, especially when the pixel pitch is greater than 25mm, the brightness loss increases with the increase of the pitch

Embodiment Construction

[0014] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0015] The large-pitch full-color LED display pixel structure of the present invention is suitable for a large-pitch pixel structure with a pitch between pixels of more than 25 mm. In this example, the preferred pixel pitch is 36mm. Because the present invention only relates to the configuration and arrangement of LED illuminants of different colors in the pixels of a color LED display screen, and does not relate to the specific structural design of the LED illuminants and the specific control technology for forming video data, its control software can use known Technology to achieve, so no more details.

[0016] Figure 2A It is a schematic diagram of the basic arrangement of pixels of the present invention. As shown in the figure, each pixel of a full-color LED display is composed of two red, two green and one b...

Abstract

The invention relates to a pixel structure applied to a large-pitch full-color light-emitting diode (LED) display screen, which is characterized in that: each pixel of the full-color LED display screen consists of two red LED luminous bodies, two green LED luminous bodies and a blue LED luminous body which are distributed at four corners of a rectangular region, wherein the two green LED luminousbodies are arranged at the opposite corners, the two red LED luminous bodies are arranged at one light-emitting point position and the blue LED luminous body is arranged at the opposite corner of thered LED luminous bodies; a pitch between pixels is in the range of 25 to 42mm; and a center distance between the two red LED luminous bodies is in the range of 4 to 7mm. Due to the adoption of the pixel structure, the display brightness can be obviously improved under the condition of a large pixel pitch, and a virtual pixel technology can be realized on the premise of ensuring that the brightness is not lost, so that the image effect of the large-pitch display screen can be greatly improved.

Description

【Technical field】 [0001] The invention relates to a full-color LED display screen, in particular to a pixel structure applied to a large-pitch full-color LED display screen. 【Background technique】 [0002] The color rendering principle of the full-color LED display is to use the different combinations of the three primary colors, namely red, green and blue, to change the color by controlling the ratio of each color channel, which is commonly referred to as the gray scale, the higher the gray scale , indicating that the greater the change of each color channel is, that is to say, the more each primary color changes from light to dark, the more the combination of the three primary colors changes from light to dark, so the color reproduction of the video source is better. Well, it will be the closest to the real program color. This also makes it possible to use human factors to intervene in display effects, so that the same program source can adapt to different environmental b...
