PHASE LOCK LOOP BASED DISPLAY DRIVER FOR DRIVING LIGHT EMITTING DEVICE AND RELATED DISPLAY APPARATUS GENERATING INTERNAL CLOCK BASED ON EXTERNAL CLOCK

摘要

Described in example embodiments herein are techniques for reducing requirements of a driver for external high frequency clock signals. In accordance with one example embodiment, a driver for driving a light emitting device includes: a data register and a phase lock loop. The data register is utilized for storing driving data for driving the light emitting device. The phase lock loop is utilized for generating a second signal according to an input first signal. The operation of the data register is controlled according to one of the input signal and the second signal, while the driving of the light emitting device is controlled according to the other of the input signal and the second signal.
