US 2014/0198086 A1 · SOURCE DRIVER AND DISPLAY DEVICE

Abstract

A source driver including a controller, a plurality of flip-flops, a plurality of shift registers and a plurality of driving channels is provided. The controller extracts control information from an image data stream. Each of the flip-flops respectively receives a corresponding control bit of the control information, and output the corresponding control bit. The shift registers correspond to the flip-flops one by one, and sequentially transmit an enable pulse. Each of the shift registers determines whether to output the enable pulse according to the control bit outputted by the corresponding flip-flop. The driving channels correspond to the shift registers one by one. Each of the driving channels switches an operation state into an enable mode or a disable mode according to the enable pulse outputted by the corresponding shift register.
