LCD splicing screens are divided into optical seamless LCD splicing screens and electronic seamless LCD splicing screens. The realization principle of the optical seamless LCD splicing screen is to install a special optical glass panel body on an ordinary 3.5mm panel, and realize the principle of line-of-sight refraction through the glass, so that the originally split screen can be seen in an image through the optical glass , The seams with black edges are completely invisible, and the display effect of the picture is real. The realization principle of seamless LCD splicing screen electronics is that by installing a special electronic bar on each panel unit, the electronic bar emits light equivalent to LED, and the light is emitted by two electronic bars between the seams, which can be displayed on the display. Achieve seamless seams. The seamless LCD panel joining technology has reached an unprecedented level, realizing the arrival of the era of true seamless joining technology. The seamless LCD panel joining technology is used in the high-end display field. It can be said that the visual impact it brings is also unprecedented. The seam adopts full-screen active LED electronic pixel compensation display, and the optical lens and optical refraction principle are seamless. The pixel pitch of LED electronic pixel correction is 1.5mm or less. The electronic pixel compensation LED adopts SMD label technology and does not use large particle lamp-like display. After LED electronic pixel correction, the edge of the condenser lens with high transmittance is added to

Liquid crystal display (LCD) is a kind of display using liquid crystal as material.   What is liquid crystal? In fact, liquid crystal is a kind of material between solid and liquid. When heated, it will appear transparent liquid, and when cooled, it will crystallize into chaotic solid. Liquid crystal is an organic compound with regular molecular arrangement.   According to the different arrangement of molecular structure, liquid crystals can be divided into three types: Smectic liquid crystals similar to clay, Nematic liquid crystals similar to thin matchstick and Cholesteric liquid crystals similar to cholesterol.   The physical properties of these three kinds of liquid crystals are not the same. Nematic liquid crystals of the second kind are used in liquid crystal displays. The molecules are long rods. In the natural state, the long axes of these long rods are roughly parallel.
