How to determine the quality of led advertising car
Led advertising car believe that we are all seen, because led lights are now very popular, such as signs outside the store, ah, ah things such as concerts are made with led. The use of LED billboards has also been stunned. If we want to buy led advertising car when we judge how the quality of led screen is superior?
First of all, to observe the flatness of the entire screen, if it is more obvious, then the quality is more worrying, probably the error of the screen flatness should be controlled within a millimeter, the error is too large, will cause the viewing led screen Dead ends affect the effectiveness of advertising.
Second, since it is led advertising, it must be colorful, more eye-catching, so the brightness needs to find a suitable range, if the brightness is not enough, then the viewing of advertising content has become a problem. Two degrees too high, too much eye stimulation, can not watch for a long time, affecting advertising from time to time. White balance for the led advertising car is also very large, white balance is in place with the led control system, the best choice for a relatively high degree of color reproduction, saturation and the like data should be moderate. The degree of reduction has a great impact on the display of the entire color and the distortion effect, and special attention needs to be kept in mind.
Finally, there is no interference with mosaics and black spots. Black spots exist because of the die. If the die is damaged due to necrosis of the die, then it cannot be displayed and there is a dark spot. The quality of the connector will not cause the above situation. Color blocks are also a big problem. Simply speaking, color blocks are the color difference between nearby colors. If there is a large block of color, it is still related to the entire background control system, scanning frequency is not high, the gray level is low.
