Implementation method for seamless splicing point-to-point display of liquid crystal screens

Abstract

The invention provides an implementation method for seamless splicing point-to-point display of liquid crystal screens. The display resolution of the liquid crystal screens is set to be a*b; a is the number of vertical pixels; the point pitches are d<LCD>; the spiced screen matrix is M*N; M is the number of horizontal liquid crystal screens; N is the number of horizontal liquid crystal screens; the method is characterized in that gaps between the liquid crystal screens are filled with three-color LED lamps; the implementation method comprises the following steps: (1) determining horizontal point pitches d<LCD-M> and vertical point pitches d<LCD-N> of a three-color LED lamp array,......, and (5) dividing a picture with the fixed resolution (a+x*M)*(b+y*N) according to the arrangement positions of the liquid crystal screens and the three-color LED lamps and achieving point-to-point display of spliced gaps of the three-color LED lamps. According to the method provided by the invention, the problem of black edges generated by borders free of a display function in the splicing process of the liquid crystal screens is solved; the seamless splicing point-to-point display effect for large screens can be achieved at relatively low cost.

Description

technical field [0001] The invention relates to the technical field of video image display, in particular to a method for realizing seamless splicing point-to-point display of liquid crystal screens. Background technique [0002] Due to the relatively mature development of liquid crystal display technology at present, liquid crystal display has the characteristics of high definition, thin thickness, energy saving, and low cost. 46 inches and 55 inches. According to the requirements, it can be spliced ​​into a display size of M×N to meet the requirements of the display system. And there will be a black seam between the two DID LCD splicing screens, which directly affects the display effect. With the continuous development of technology, the frame of the used DID LCD splicing screen is getting smaller and smaller, and the seam size of the frame of the DID LCD splicing screen has been reduced from the initial 22mm to the current 1.8mm. DID LCD splicing screen manufacturers h...

Problems solved by technology

The disadvantage of this technology is that it is more affected by the viewing angle of the user, and the observation range is smaller

[0004] In the existing edge-mounted LED technology, the LED displays a light band, which can make up for the defect of the black seam, and can display an image close to the LCD screen, but it still cannot achieve the pixel-to-point display effect of the displayed image
