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

At present, the trend of semiconductor display industry chain transferring to China is becoming stronger and stronger, which strengthens the scale advantage and geographical advantage of domestic enterprises, promotes the continuous improvement of service and cost competitiveness, puts more and more pressure on Samsung and other enterprises, forces them to change the track, and domestic manufacturers will enter the “harvest period”.   LCD (liquid crystal display) industry once flourished in the United States and Japan, and then began to blossom and bear fruit in Korea and China. As an industry with significant scale effect, high capital barriers and prominent strategic position, expanding higher generation production lines against the industrial cycle is the core driving force for the long-term decline of industry costs and the continuous creation of new application markets.   Since the beginning of this year, the whole LCD market has been full of smoke. Whether the South Korean panel giant announced the closure of LCD production line, or the integrated sale of related domestic listed companies, the industry is full of highlights.   Will domestic manufacturers enter the “harvest period”? Since the beginning of this year, Samsung and LG, the two South Korean panel giants, have successively announced the closure of most LCD (liquid crystal display) production lines. India predicts that the proportion of Korean production capacity will decrease from 23% in the first quarter of 2020 to 8% in the first quarter of 2021.   A display industry analyst told the daily economic news that at present,
