Problem 1 & 2: Pixel Shadow + Bad Grey scale.
With S-PWM Driver IC solution, the Pixel shadow and bad grey scale problems solved successfully, also we can get a very good image quality led screen.
Problem 3 & 4 :BAD white balance +Cross dead pixel.
A Bad white balance led display will effect the image quality, even HD resolution pixel led display, and with S-PWM driver IC can solve the Cross DEAD pixel problems.
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.
