Generally speaking, when the full-color LED display screen runs for a certain period of time, all LED light-emitting tubes will inevitably have brightness attenuation, and the attenuation curves of the three primary color tubes are not the same. So their brightness will be lower than when they left the factory. Because of the difference in the photoelectric characteristics of each LED light-emitting tube, the degree of brightness reduction is error. Therefore, after the display screen is actually used for a period of time, the brightness of the light-emitting tube will be attenuated to different degrees, which will make the display between the pixels not uniform enough, and then compare with the factory screen to show a granular display state , Or the overall brightness is reduced. The inconsistent decay curves of the three primary color tubes will cause changes in white balance and color temperature.

Due to factors such as the attenuation of the LED light-emitting tube and the ambient temperature, in practical applications, it is almost inevitable that the display function will deteriorate at the time of shipment. It is impossible to complete the installed full-color LED display screen and transport it back to the supplier for calibration. In view of these characteristics, it is necessary for full-color LED display manufacturers to perform calibration on site to ensure In future applications, the display can still maintain the same effect as it was at the factory.

The hotel needs to pay attention to the choice of indoor full-color LED display

More and more full-color LED displays are entering indoors, especially large hotels, and they are favored by many advertisers. Usually an area larger than 5 square meters will be used for indoor full-color LED displays. Its advantages are high brightness and no seams. The hotel's indoor full-color LED display is the most used.
