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,

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.

The display screen can be divided into three types: normal temperature, wide temperature, and ultra-wide temperature according to the supported working temperature range. The normal temperature display supports the working temperature between 0 °C and 50 °C, and the wide temperature display supports the working temperature between -20 °C and +70 °C. ℃, the ultra-wide temperature display supports the working temperature between -40℃～+90℃. Usually, the display screen with good low-temperature performance will have poor high-temperature performance. The wider the operating temperature range, the higher the price. Users can choose suitable display products according to actual use conditions.
