Patent ID: 7486267

Claim:
A driver for a display device, outputting a plurality of driving signals to drive a plurality of electrode lines, the driver comprising: a plurality of output devices respectively outputting the driving signal, each comprising: an amplifying unit having a first input terminal, a second input terminal, and an output terminal outputting the driving signal, wherein the amplifying unit is configured with a feedback loop, wherein the amplifying unit comprises: a first-stage amplifier having first and second input terminals respectively coupled to the first and the second input terminal of the amplifying unit, and an output terminal; a second-stage amplifier having a first input terminal, a second input terminal coupled to the output terminal of the first-stage amplifier, and an output terminal coupled to the output terminal of the amplifying unit; wherein the feedback loop is configured between the first input terminal and the output terminal of the second-stage amplifier; and a control unit configuring in the feedback loop and controlled by a control signal; wherein when the amplifying unit receives an input signal, the control unit turns off the feedback according to the control signal for a first period so that the amplifying unit rapidly drives the corresponding electrode line toward the driving signal based on the input signal, and then the control unit turns on the feedback according to the control signal after the first period so that the amplifying unit maintains the corresponding electrode line at the driving signal based on the input signal.
