The specific form of digital signage

Since the start of LCD advertising machines in 2002, the digital signage industry has been developing for more than ten years. What’s interesting is that with the development of the digital signage industry, the concept of digital signage is becoming more and more blurred. The industry has not yet been able to give a complete and authoritative definition of sports norms, and the development of the digital signage industry has begun to slow down. So what are the specific manifestations of digital signage? 1. Advertising machine series As the ancestor of the introduction of digital signage, the position of advertising player in the field of digital signage is unshakable. From LCD advertising machine to network advertising machine; from indoor advertising machine to outdoor advertising machine; from pure broadcast advertising machine to interactive advertising machine. The development of advertising machines has been at a steady pace, and the development of China’s advertising machine industry has become more refined and refined. A company may specialize in the production of advertising machines at airports, subway stations, or bus stop sign advertising machines. However. Nine children and a mother, don’t forget, we all belong to a big family of advertising players! And the advertising machine series is the fundamental source of digital signage. However, due to the limitation of non-state-owned source technology, the development of raw material technology and quality in the advertising player industry has entered a bottleneck stage. Most advertising player manufacturers choose to temporarily put aside the source technology development of

What is the function of LCD Polarizer?

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. Without

When customers use LCD, what should they pay attention to?

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.
