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.

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,

The following are the precautions for LCD module operation:   If the display screen is damaged and the internal LCD leaks, do not let it enter the mouth. If it gets on clothes or skin, wash it quickly with soap and water. In order to reduce static electricity, do not carry out assembly and other work in dry environment. The LCD module has a film to protect the display screen. Be careful when removing this protective film as it may generate static electricity. The display screen is made of glass. Do not apply mechanical impact, such as falling from height. It must be grounded correctly. Minimize electrode corrosion. Water droplets, moisture condensation or current in high temperature environment may accelerate electrode corrosion. At low temperature, liquid crystal solidification will lead to directional defects or bubbles. When the liquid crystal module is subject to strong vibration at low temperature, bubbles will also be generated. If the LCD module works for a long time and displays the same pattern, the pattern will remain on the screen like a phantom, and there will be subtle contrast differences. If you want to regain the normal working state, you can temporarily stop using it for a while. It is worth noting that this phenomenon will not have an adverse effect on the reliability of the performance.
