The display screen can be divided into three types: normal temperature, wide temperature, and ultra-wide temperature according to the supported working temperature range. The normal temperature display supports the working temperature between 0 °C and 50 °C, and the wide temperature display supports the working temperature between -20 °C and +70 °C. ℃, the ultra-wide temperature display supports the working temperature between -40℃～+90℃. Usually, the display screen with good low-temperature performance will have poor high-temperature performance. The wider the operating temperature range, the higher the price. Users can choose suitable display products according to actual use conditions.

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.

As a new type of identification product, digital signage has some personalized functions that traditional signs do not have. It is precisely because of these distinctive functions that it can occupy a place in the market, and now digital signage has embarked on The fast lane of rapid development. So, have we found that in different scenarios, the role and function of digital signage are different, and the way of interaction is also different. The root cause of this problem is that user needs are different, so it is necessary to customize functions according to user needs Development, now the problem is coming again. From the current digital signage on the market, what are the common functions of digital signage? Below we expand from three aspects; 1. Queuing for number collection. This function is actually a more traditional function, and it is also a function that we have more contact with. For example, when we go to public places to do business, due to the large number of people, we need to give each user a number, according to the number The order of work is done in order, so that the order is easy to maintain, and the work efficiency is high. To solve this user’s pain point, the function of digital signage self-checking is not suitable. In addition, there are some file-like materials that can also be self-printed through digital signage. In fact, many self-service terminals can be counted as digital signage.   2. Guides and guides. In
