Pixel combination of full color led and white led for use in led video displays and signages

摘要

A signal processing device and method for driving one or more light emitting diodes ("LEDs") of a video screen, display panel, module or other component. The signal processing device and method can control one or more RGB LEDs and/or white LEDs to produce light with increased uniformity and brightness at a reduced cost and having reduced power consumption. The signal processing device and method can generate a matrix brightness value based on one or more input LED driving signals; generate a complementary brightness value based on the one or more input LED driving signals; generate an LED driving signal based on the matrix brightness value and the complementary brightness value; and delaying the one or more input LED driving signals to generate one or more delayed LED driving signals.
