Spot-spot Correction Technology of LED Display
LED display is gradually accepted in the market with the features of energy conservation, environmental protection and high brightness. It's been widely used in advertisements market, expositions and exhibitions, recreation and acting areas.LED technology not only applied to traffic guide board, but also car light and lighting source direction screen, to be demotic that is more energy saving, more environmentally friendly "service" technology products.
LED display consists of several LEDs, even the same batch of LEDs can be different in brightness and wavelength discreteness which causes the different effects on the screen. Currently, only spot-spot correction technology can improve display consistency and color restore extent. Besides, sophisticated spot-spot correction technology can realize the mixed usage of different batches of LEDs with good display consistency and color restore extent. On-site correction can be realized at the proper viewing spot to make sure the high consistency of the display. This function can make an one-year old display change to a new one.
LED display technology is developing more and more sophisticated, among which, spot-spot correction technology is one of the newly developed technologies and will be the essential technology. As there are photedegradation and picture uniformity decrease during the usage, thus on-site correction technology becomes another important technology manufacturers should master. With the two advanced technologies, we can provide more perfect products and services to customers.
