Abstract
A source driver for driving a panel includes an output buffer. The output buffer includes a first amplifier, a second amplifier, and an internal switching unit. The first amplifier includes a first stage and a second stage. The second amplifier includes a first stage and a second stage. The internal switching unit selectively connects the first stages and the second stages of the first amplifier and the second amplifier. At a charge sharing stage, the internal switching unit performs charge sharing between the second stage of the first amplifier and the second stage of the second amplifier.

A source driver for driving a panel, comprising:
- an output buffer, comprising:
- a first amplifier, having a first stage and a second stage;
- a second amplifier, having a first stage and a second stage;
- and
- an internal switching unit, for selectively connecting the first stages and the second stages of the first amplifier and the second amplifier;
- wherein at a charge sharing stage, the internal switching unit performs charge sharing between the second stage of the first amplifier and the second stage of the second amplifier.
A method for controlling a display, the display comprising a source driver and a panel, the source driver comprising an output buffer, the output buffer comprising a first amplifier having a first stage and a second stage, a second amplifier having a first stage and a second stage, and an internal switching unit, the method comprising:
- during a charge sharing stage of a first line period, performing charge sharing between the second stage of the first amplifier and the second stage of the second amplifier via the internal switching unit;
- and
- during a driving stage of the first line period, connecting the first stage to the second stage of the first amplifier, and connecting the first stage to the second stage of the second amplifier via the internal switching unit, so as to drive the panel.
