In the past a few years, small pixel Pitch led screen in all the head lines of led screen papers, this series led screen require very strict technology, from PCB, driver IC solution etc, in small pixel pitch led screen development,, we have met many many problems,
Problem 1 & 2: Pixel Shadow + Bad Grey scale
Problem 3 & 4 :BAD white balance +Cross dead pixel.
Problem 5: Bad contrast rate.
Macroblock S-PWM driver IC solution is specific developed for small pixel led screen to solve these problems, because small pixel pitch led screen is very difficult to repair if some pixels have problems, so that we have to ensure every pixel is stable and use the best solution for customers.
