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.

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.

With the rapid development of digital information technology, the overall technology in the urban transportation field has also been effectively improved, and information modernization and intelligence have gradually been realized, and “smart transportation” has gradually been realized from the concept. Based on the background of smart transportation, how to realize the smart display of traffic information is the key. In-depth analysis of the application and advantages of digital signage in smart transportation, aviation, subway and rail transit. Airport flight display application With the rapid development of social processes, the digital construction of urban airports not only assumes the responsibility of aviation infrastructure, but also becomes the central hub of regional economic integration and urban internationalization. The year-on-year increase in passenger throughput and the continuous improvement of airport service quality have placed stringent requirements on real-time information updates and display equipment at the airport. Actually used in airport scenarios, digital signage can be used as a large aviation display screen to realize the intelligent display of information. On the one hand, after being equipped with the CMS messaging system, it can realize the unified scheduling and control of the information released by multiple terminal devices, present flight and boarding gate information in real time, realize flight information guidance, meet the needs of passenger flow information identification, and can also follow up in time. Check-in status of each flight to enhance the passenger’s flight experience; in addition, information such as flight number, remaining flight tickets, city weather and other information can also
