Why are LED display dimming? It is a very common phenomenon that LED screen become dimmer after use long time. To sum up the reasons that what make LED screens dim, nothing more than the following three points.
Point 1. Driving IC problem
Therefore, a stable and high-quality driver is the premise to ensure the normal use of the screen. For linsn led factory, we have strict supplier selection and quality control for the procurement of drivers.
Point 2. LED lamp problem
A) the whole screen play white, the led video wall should be pure white, without any other noise.If you think it’s okay to be a little red or a little blue, you’re wrong, because color bias proves that there are problems with the display material and process quality control.Use time long, can more and more serious.
B) play red, green, blue monochrome, the color of the center wavelength is usually we say positive blue positive red positive green, if a little darker or lighter color, it is a partial wavelength.If a certain color is inconsistent, it is proved that the wave difference is too large. The high-quality display screen is within the range of the central wavelength, the blue-green wave difference is controlled at 3nm, and the red wave difference is less than 5nm.
