Abstract: A source driver adapted to drive a plurality of data lines on a display panel is disclosed. The source driver includes a first output buffer, a second output buffer, a multiplexer, and a first regulating unit. The first and the second output buffers respectively enhance transmission intensities of a first and a second pixel signals. The first regulating unit regulates a slew rate of the first pixel signal outputted from the first output buffer to match a slew rate of the second pixel signal outputted from the second output buffer. The multiplexer coupled to the regulating unit selectively transmits the first and the second pixel signals to one of the odd data lines and one of the even data line, or to the one of the even data lines or the one of the odd data lines, according to a control signal.

Abstract: A display includes a panel, a timing controller, and a source driver. A method for driving the display includes the steps of sending a transfer signal asserted for a first period to the source driver initially at a line period; sending a driving control signal asserted for an asserted period to the source driver by the timing controller initially at a line period, utilizing a large driving capability of the source driver to drive the panel during the asserted period within the line period, and utilizing a small driving capability of the source driver to drive the panel beyond the asserted period within the line period.

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.

Abstract: A low noise amplifier including a first-stage signal amplifier, a second-stage signal amplifier and a gain control unit is disclosed.
