Embodiment Construction

[0041] In order to improve the brightness and resolution of the existing full-color LED display to meet the needs of semi-outdoor display, the invention provides a high-brightness, high-resolution LED display. The high-brightness, high-resolution LED display screen is the same as the existing three-primary-color LED display screen, and is composed of pixels composed of a plurality of three-primary-color diodes arranged in a matrix. In order to improve the brightness of the present invention, the pixel points formed by the three primary color diodes arranged in a matrix are composed of four LED diodes, and its structure is as follows: figure 1 shown. The four diodes constituting one pixel point are four diodes R1, G, B, and R2, and the four diodes are located at the four corners of the unit matrix with side length a. The arrangement order of the four diodes is that the two red diodes R1 and R2 are located at the diagonal points of the unit matrix. Arranged in this way, it can...

Abstract

The invention relates to a LED display with high brightness and resolution. The LED display comprises a pixel point consisting of tricolor diodes queued in a plurality of matrixes, wherein: the pixel consists of four LED diodes. The invention has the advantages of big visual angle, high resolution, even brightness, convenient processing, low cost, high reliability, etc.

Description

technical field [0001] The invention relates to a light-emitting diode display screen, in particular, the invention relates to a high-brightness, high-resolution LED display screen and a driving method thereof. Background technique [0002] The brightness, gray scale and resolution of full-color light-emitting diode (LED) displays are the main factors in the quality of digital images. [0003] For the brightness of the LED display, the brightness requirements are different under different working conditions, which can be divided into three types: outdoor, indoor and semi-outdoor. [0004] 1. Outdoors in the sun requires a brightness of 6000--7000cd / m 2 ; [0005] 2. Indoor 500--800cd / m 2 ; [0006] 3. Semi-outdoor 3800--4000cd / m 2 . The so-called semi-outdoor refers to not being exposed to direct sunlight, and not being the brightest moment at noon. [0007] Generally used full-color light-emitting diodes are composed of diodes of R, G, and B colors to form a pixel. ...
