ABSTRACT:
A digital display driving circuit is provided for driving a light emitting diode (LED) display to generate video images. The digital display driving circuit comprises a digital gamma-correction circuit for performing a digital gamma-correction process on the digitized video data to produce the desired video signals. An LED timing control circuit is applied for converting a plurality of timing signals into an LED timing control signal. And a PWM and shutdown circuit is applied for supplying power to the LED display and shutting down the LED display when the LED display has been idle for a preset period.
