Outdoor full color led display brightness why not inconsistent, what is the reason for it? Once again strong giant color to tell you, led to the brightness of the LED display is not the main reason for the light-emitting elements and driven the original two factors caused.
Light is the original LED led light pipe, in the production process which is inconsistent brightness is an unavoidable problem, but the led display manufacturers to take the action is completed in the production of the led display will be sub-file, adjacent to the two files The smaller the brightness gap, then the consistency will be better, but will result in low yield and high inventory of the phenomenon more and more serious. Therefore, the various manufacturers are adjacent to the brightness difference between the two files in the control of about 20 percent.
And we said the drive components are generally constant current driver chip, the chip is full of sixteen stable constant current drive output, you can use the resistance set circuit output value, the same chip output error is generally controlled in the percentage Of the three, but the different chip output error is generally controlled within six percent.
In addition, we need to pay attention to the LED display brightness is inconsistent, but also caused the main reason Huaping display screen, Huaping phenomenon can not be used to solve the late correction, only through the led display manufacturers to achieve the manufacturing process. So the purchase of the brightness of the inconsistent led display, to contact the manufacturers or businesses to solve the problem
