digital signage display stands

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.

1. Keep the humidity in the environment where the digital signage is used, and don’t let anything with damp properties enter your digital signage. Powering on digital signage that contains moisture will cause corrosion of the digital signage components and cause permanent damage. 2. To avoid problems that may be encountered, we can choose passive protection and active protection, try to keep the items that may cause damage to the digital signage away from the screen, and when cleaning the screen, wipe it as gently as possible to reduce the possibility of injury Minimize. 3. The relationship between digital signage and our users is the closest, and it is very necessary to do a good job in cleaning and maintenance. After being exposed to wind, sun, dust, etc. in an outdoor environment for a long time, there will definitely be a piece of dust on the screen after a period of time. This needs to be cleaned in time to prevent dust from covering the surface for a long time to affect the viewing effect. 4. It is required that the power supply is stable and the grounding protection is good. Do not use it under severe natural conditions, especially strong thunder and lightning. 5. It is strictly forbidden to enter the screen body such as water, iron powder and other easily conductive metal objects. Digital signage should be placed in a low-dust environment as much as possible. A large amount of dust will affect the display effect, and too

The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen
