Abstract

A pixel-shared displaying device for LED screen is composed of the video source of digital signals, scan board and display screen. Its display method includes such steps as defining 4 scan coordinates for LEDs on screen according to display modes, setting up relative field sequence for each scan coordinate, storing the scan coordinates and field sequence to the frequency quadrupler, controlling scaning of scan board by 4x frequency and outputting the signals from digital video source to screen.

Description

technical field [0001] The invention belongs to the field of LED display screen display methods, in particular to a LED display screen pixel sharing display method and a device thereof. Background technique [0002] The most basic unit of a digital image is a single pixel, and the quality of a digital image is mainly restricted by two factors. The first is the pixel density of a digital image, which we usually measure by resolution, and the second is the color level that a single pixel can express, that is, the number of bits or grayscale of an image. The same image is definitely better represented by a display medium with a resolution of 1024*768 and a color level of 24 bits than with a display medium with a resolution of 640*480 and a color level of 16 bits. The LED display is a typical digital image display medium, so in order to improve the display effect of the LED display, we should start from two aspects. First, increase the density of LED lights, and second, increa...
