The working principle for the LCD screen panels

How Does An LCD Screen Work? Answering A Liquid Crystal Display Tech Question #LCD #Tech   You can find Liquid Crystal Display (LCD) technology everywhere: in TVs, computers, tablets, laptops, smartphones, watches, monitors, displays, calculators, cellphones, smartwatches, and many more… but do you know how this awesome tech works? Do you also know that the working principle of LCD is pretty similar to the newer LED backlit based screens (edge LED or direct LED)? So today, we explain how an LCD screen work by looking inside an LCD screen and detailing all of its layers. We will talk about the reflector sheet, the Light Guide Plate (LGP), the Dual Brightness Enhancement Film (DBEF), the diffuser sheet, the prism sheet, the bottom polarizer, the bottom glass substrate (backplane), the Thin Film Transistor (TFT), the Liquid Crystal, the Common electrode, the color filter (RGB), the top glass substrate, the top polarizer, and the top chassis and frame. Understanding how a screen works can be especially handy to know if you like clever technology or to understand if your screen breaks down, and you need to figure out what is going on to repair it… knowledge is power!

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.

Advantages of digital signage in smart transportation scenarios

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
