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

As an important carrier of indoor and outdoor advertising, LED display has a natural connection with advertising media. The survey found that in the past year, although the share of LED display in the outdoor application commercial market has shown a growth trend, the growth driver is not the increase in the number of screens, but the value-added of the original screens. According to the statistics of the authoritative research organization HIS, the global digital signage market revenue exceeded 15.1 billion U.S. dollars in 2018, an increase of 6% over the previous year. Among them, the digital signage display that occupies the largest share will achieve more than 6 billion U.S. dollars in revenue by 2021, creating a good development opportunity for the commercial display industry. This means that with the increase in application commercial market demand, the traditional business model is no longer able to promote the sustainable development of the industry. If the LED display industry wants to grow steadily, it must take a refined route and refine its applications. The development of the indoor application commercial market and the heavy investment in digital signage by display manufacturers are just a new attempt to this kind of change. LED advertising machine is also another mode for LED screen to penetrate into the field of digital signage The development of technology and the continuous improvement of market awareness have made the outdoor application of digital signage a trend, and the market scale has expanded rapidly.
