LCD seamless splicing screen display technology

The liquid crystal seamless splicing screen display technology is a splicing screen body which adopts a professional-grade ultra-narrow side LC seamless splicing screen D display unit splicing method, and realizes a large screen splicing display effect through a splicing control software system. LCD liquid crystal splicing is a new splicing technology that has emerged in recent years. The English name is LiquidCrystalDisplay. The LCD is constructed by placing liquid crystals in two parallel glass. There are many vertical and horizontal small wires between the two glass. Control the direction of the rod-shaped crystal molecules by energizing or not, and refract the light to produce a picture. The LCD consists of two glass plates, approximately 1 mm thick, separated by a uniform spacing of 5 μm containing liquid crystal material. Because the liquid crystal material itself does not emit light, there are lamps on both sides of the display screen as a light source, and on the back of the liquid crystal display, there is a backlight plate (or a homogenizing plate) and a reflective film, and the backlight plate is composed of a fluorescent material. The light is emitted, and its function is mainly to provide a uniform background light source. The light emitted by the backlight enters the liquid crystal layer containing thousands of liquid crystal droplets after passing through the first polarizing filter layer. The droplets in the liquid crystal layer are all contained in a small cell structure, and one or more cells constitute one pixel on the screen. Between the glass plate and the liquid crystal material is a transparent electrode, the electrode is divided into rows and columns, at the intersection of the row and the column, by changing the voltage to change the optical rotation state of the liquid crystal, the liquid crystal material acts like a small light valve . Around the liquid crystal material are a control circuit portion and a drive circuit portion. When the electrodes in the LCD generate an electric field, the liquid crystal molecules are distorted, and the light passing through them is regularly refracted, and then filtered through the second layer of the filter layer to be displayed on the screen.
