SOURCE DRIVER AND DISPLAY DEVICE

摘要

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.

1. A source driver, comprising:
a controller, extracting control information from an image data stream; a plurality of flip-flops, electrically connected to each other in series, receiving the control information, wherein each of the flip-flops respectively receives a corresponding control bit of the control information, and output the corresponding control bit; a plurality of shift registers, electrically connected to each other in series, and corresponding to the flip-flops one by one, wherein the shift registers sequentially transmit an enable pulse, and during a process of transmitting the enable pulse, each of the shift registers determines whether to output the enable pulse according to the control bit output by the corresponding flip-flop; and a plurality of driving channels, corresponding to the shift registers one by one, wherein each of the driving channels switches an operation state to an enable mode or a disable mode according to the enable pulse outputted by the corresponding shift register.
