Now with the development of society, LED displays will be widely used in banks, securities, transportation (highways, airports, railway stations, subways, etc.), hospitals, stadiums, entertainment, advertising and leasing and other places. In sports venues and road traffic instructions, it will also directly promote the rapid increase of the number of stadium screens, and because the Olympic screens have also improved a lot compared to the quality requirements of LED displays, the use of high-end LED displays The above will also gradually increase, and the improvement in quantity and quality will also drive the development of led display screens.

In addition to sports venues, LED display screens also have and promote the advertising field in the Olympic Games, World Expo and large-scale sports activities, so domestic and foreign advertising companies will be optimistic about the Olympic Games, World Expo and other large-scale sports events, and will also bring business opportunities. It will inevitably increase the number of outdoor advertising displays to increase their own income, thus promoting the development of the LED display market.

So, how do we control and improve the technical problems of LED display pixels? Now the commonly used methods are: a, pixel sharing technology b, dynamic pixel technology c, virtual pixel technology, these three methods.

How should we understand these three methods? How does it work? Let's briefly introduce:

a. Pixel sharing technology: A complete independent pixel of the display terminal is cyclically refreshed by the information of multiple adjacent pixels in the signal source in a time-division multiplexed manner. That is to say, multiple pixels in the signal source share a complete independent pixel of the display terminal in a time-division multiplexing manner.

b. Dynamic pixel technology: split a pixel into several independent LED units, and each LED unit reproduces the corresponding primary color information of several adjacent pixels in a time-division multiplexed manner.

c. Virtual pixel led video wall technology: In the display system, when the displayed information scrolls in a certain direction in a certain way, using the characteristics of human visual pause, a series of movements will occur between two adjacent pixels, Physically non-existing virtual pixels, so as to adjust each LED single tube to enhance the resolution of the LED display to achieve the best image effect, that is to say, the image resolution can be increased by 4 times.

To sum up, in addition to the pixels, the LED display technology is far from enough. It must also include high brightness, gray scale, scanning refresh rate, viewing distance and viewing angle. The value of the LED display is also through the color reproduction, It is judged by the video signal processing ability and structural technology!
