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.

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.

Digital signage has been developed for many years, but due to various objective reasons, it has not yet been popularized on a large scale. However, in some government service establishments and high-end commercial establishments, digital signage has been widely adopted. This shows that digital signage Signage is moving forward along the logical route of commercial development, and it has not stopped, let alone its development. Based on years of experience in digital signage projects, we believe that the following three changes are initially expected in digital signage in the next three to five years: Development trend 1, response methods will be more diversified As far as the interactive mode of digital signage is concerned, the response mode is relatively simple. Basically, it is operated by the touch screen. After clicking, the digital signage will make corresponding actions according to relevant instructions, such as issuing tickets and so on. However, people’s pursuit is endless, and more needs have not been met for the time being. At this time, new solutions are often needed to solve these pain points. Therefore, will there be new ways to respond in the future? , The answer is yes, such as voice interaction, voice interaction, and interconnection with mobile phones, etc., may be the specific form of future response methods. Development trend 2, the full integration of reality and virtual We are no longer unfamiliar with the terms augmented reality (AR) and virtual reality (VR), because over the years, the development of AR and VR has
