Recently, the price rise trend of LCD is very obvious. Some original manufacturers have adjusted the ex-factory price many times, and some even adjusted the price more than 20% at one time “A panel factory recently raised its price twice in a row, each time adding 5 yuan to the original price. In fact, this kind of increase is not surprising in the industry”. The source said.   The cause and effect of this price increase   As for price increase, we are more concerned about price increase, duration and category. In fact, in this round of price increase, the rise of different LCD screens is not the same.   There are structural differences in the price increase. The main performance is that the price of low-end LCD products increased by 20% – 30% or even 40% – 50%.LTPS (low temperature polycrystalline silicon) screen and AMOLED (active matrix organic light emitting diode panel) used in high-end mobile phones have little or no price increase. At the same time, 32″ and 38.5″ LCD screens for small size TV sets have fallen below the cost price of materials, and manufacturers have been seeking price increases in recent months, while the price of 70″ or more LCD screens for large size TV sets has not fluctuated much.

In fact, dark spot is more hidden than bright spot and bad spot, but its influence on use is far greater than bad spot. Sometimes on some screens, there will be some patches that are not very big. The black small class is as big as the soybean, and the big class may be as big as the thumb. Different from the bright and dark spots, the dark color system is only partially dark, which is not easy to find from the front, but only from the side.   The main reason for the formation of dark spots is that the external force has been squeezed for long time. We think that it is probably due to improper handling in the transportation process. LCD screens with black dots are usually hard to find on the front and more obvious on the side (just like the test perspective).We suggest that when you buy LCD, you should not only look at the bad points of the screen, but also look at the surface of the screen from multiple angles, and set the screen to white.
