What are the basic components of LCD?

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.

Daily maintenance methods for LCD advertising machines

In daily life, we must keep the habit of “cleaning” the LCD advertising machine regularly. You can spray it on the LCD advertising machine screen with a special potion, and then gently wipe it with a clean white cloth. Try not to use a damp cloth with too much water content. Too much water content on the damp cloth can easily cause water to stay on the screen. Water entering the screen through the edge can cause a short circuit in the system and the LCD advertising machine cannot work normally. It is recommended to use soft scrubbing materials such as glasses cloth and lens paper to scrub the screen to avoid unnecessary scratches on the LCD advertising machine screen. The working environment of the LCD advertising machine directly affects the operation and service life of the LCD advertising machine. If the working environment of the LCD advertising machine is too bright, or even direct sunlight, this will not only affect the visual communication of the LCD advertising machine, but also damage the LCD advertising Machine screen electronic components. The air humidity of the working environment where the LCD advertising machine is located must be kept suitable, and two extremes must not be taken. Once the electronic equipment is too humid, it will only affect the circuit conditions and cause the LCD advertising machine to fail to work normally. No matter how good electronic products are, they will have their own longest operating time, and LCD advertising machines are no

The difference between LCD splicing screen and LCD display

With the popularization of the construction of national smart cities and safe cities, LCD splicing screens, as the best terminal display equipment, are favored by various industries and are perfectly integrated into our lives; as we all know, the LCD splicing industry is a sunrise industry with broad development. The prospects and entry barriers are extremely low. Therefore, the LCD splicing market has attracted an influx of many manufacturers, and the actual products of manufacturers are uneven. The viewing angle of the LCD splicing screen can reach 178 degrees, while the ordinary LCD can only see the 178-degree blank space. This is a very important criterion for distinguishing LCD splicing screens and LCD monitors. There is also the difference between the input signals of the two. The splicing screen is mainly the input video signal. In order to meet the interface requirements of different front-end devices, the splicing screen interface will be much richer than the display, including BNC, VGA, RGB, HDMI, DVI, S A variety of interfaces such as terminals meet the input requirements of different signals, while the monitor mainly inputs VGA signals, and the interfaces are mainly VGA, S-terminal, etc., which cannot meet the signal input requirements of various monitoring equipment. What is the difference between an LCD splicing screen and an LCD monitor, be sure to read it clearly when buying The driving scheme of LCD splicing screen is different, that is, the display motherboard scheme is different. Since the LCD display usually takes no more
