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

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

At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which
