We will use some electronic devices in our life, LCD module is one of the electronic components. Everyone’s understanding of it must be relatively strange, and then we will talk about the knowledge in this respect.   The following is an introduction to the three basic components and features of LCD. Let’s take a look with the editor: Liquid Crystal Materials Liquid crystal material is the main body of liquid crystal display. Different devices use different liquid crystal materials. Most liquid crystal materials are composed of several or even more than ten kinds of single liquid crystal materials.   Polarizer The light sheet, also known as polarized light, is made of plastic film material, coated with a layer of optical pressure sensitive adhesive, which can be pasted on the surface of the liquid crystal cell. There is a protective film on the surface of the front polarizer, which should be removed when using. The polarizer is afraid of high temperature and high humidity, which will depolarize or blister under high temperature or high humidity conditions.   Glass Substrate A kind of float production thin glass sheet with extremely flat surface, the surface of which is evaporated with a layer of zn203 or sn02 transparent conductive layer, i.e. ITO film, is processed into transparent conductive pattern. If scratched, cut or corroded, the vacuum device will be scrapped.

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. LCD agent Shenzhen weishixin Co., Ltd. Chairman Lu Naiming said.   According to reports, the last price rise cycle of LCD was from 2016 to 2017, and its overall market price has been falling since 2018.
