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

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.

With the support of policies and funds, China has become the largest LCD panel supply market in the world. According to the statistics of China Business Industry Research Institute, China’s panel production capacity accounted for about 29% in 2016, and it is expected that China’s panel production capacity will account for 56% by 2022.   LCD panel is promoted by policy, technology and capital The LCD panel industry is capital intensive, labor-intensive, and driven by market demand. The development of panel enterprises needs policy support, technology development and capital investment. LCD panel cycle weakened, the profitability of manufacturers increased significantly Due to the two-year construction period and one-year capacity climbing period, the past LCD panel showed a strong periodicity. As the industry enters the late stage of maturity, the willingness of manufacturers to build new production capacity is greatly reduced. According to our supply and demand model, the compound growth rate of LCD production capacity in the next three years will be 3.1%; The compound growth rate of LCD demand side is about 6.5%, the supply and demand pattern of the industry will be improved, the periodicity will be significantly weakened, the panel price will be maintained in a reasonable range, and the profitability of LCD panel manufacturers will be greatly improved. LCD panel has entered the era of China, and the panel “two heroes” take off The display panel industry is a key industry supported by the state, and the state has issued a number of policies to support
