Timing, PWM, Intensity Controls and Synchronization
The internal PWM dimming is synchronized to the LCD's frame timing through the PHI input (typically VSYNC) and the
GSC input (typically HSYNC) to eliminate beating artifacts and maintain high timing accuracy. Suitability for LED backlight
architectures is shown in Table 2. LED area dimming for direct backlighting is supported for contrast improvement. Motion
blur is reduced by setting each LED string's PWM phasing individually to synchronize PWM off times with the LCD refresh
timing for the zone being lit.
