Why does LCD flash? What’s the solution?

With the wide application of LCD in vehicle products, instruments and other electronic products, there will always be flashing in the process of use, which will affect the use of customers. What we should do at this time? Now we would like to share with you the causes and solutions of LCD screen flashing: The frequency of the LCD screen itself is too high, resulting in the flash screen. However, in real life, it is rare for the device to flash due to high frequency. According to the industry technical personnel, people’s naked eyes have no sense of flicker for images over 60Hz, while the design standard of general LCD screens is basically within this data range, so under normal circumstances, the frequency will not be too high, but at the same time, the screen itself will not be excluded from failure. After testing by relevant instruments, it is really the fault of the screen itself. In addition to replacing the new monochrome LCD screen, it is to design the software related to the equipment. LCD flash screen solution: the best way is to increase the OSC frequency of IC to see the flash of LCD screen. Of course, if the LCD has separate row and column drivers, it can also be adjusted by setting the driver chip.   The frequency of LCD is close to that of light source. This is very common. Because the frequency of different light source is different, in some specific cases, when the frequency

What is liquid crystal?

Liquid crystal display (LCD) is a kind of display using liquid crystal as material.   What is liquid crystal? In fact, liquid crystal is a kind of material between solid and liquid. When heated, it will appear transparent liquid, and when cooled, it will crystallize into chaotic solid. Liquid crystal is an organic compound with regular molecular arrangement.   According to the different arrangement of molecular structure, liquid crystals can be divided into three types: Smectic liquid crystals similar to clay, Nematic liquid crystals similar to thin matchstick and Cholesteric liquid crystals similar to cholesterol.   The physical properties of these three kinds of liquid crystals are not the same. Nematic liquid crystals of the second kind are used in liquid crystal displays. The molecules are long rods. In the natural state, the long axes of these long rods are roughly parallel.

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
