Global LCD industry meets market changes

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,

When customers use LCD, what should they pay attention to?

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.

What is the function of LCD Polarizer?

Polarizer is an important part of LCD screen. With the emergence of special full matching technology, polarizers are more and more widely used in LCD. What role does polarizer play in LCD?   Polarizer is widely used in LCD industry, and LCD needs to use polarizer. Polarizer and liquid crystal play an important role in development. In the production process, two pieces of ordinary tempered glass are printed on the circuit, and then glued together and folded. Then the liquid crystal is injected into the middle of the two sides of the glass, and the polarizer is pasted on the top and bottom of the glass.   The upper and lower glass should be pasted with polarizer, but pay attention to the direction. If the lower polarizer filters the x-direction light, the upper polarizer can only filter the y-direction light. If the upper polarizer filters out the light in the Y direction and the lower polarizer filters out the light in the X direction, the user can see nothing. Although the LCD works normally, the polarizer is not visible to the naked eye. Now the LCD color screen is generally only on the film, not on the film, the product technology innovation.   People who have studied physics should know what polarized light is. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizers close to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1 mm.
