    Abstract: A display device capable of decreasing an amplifier offset using a gate-start pulse signal is disclosed. A display device includes a display panel, a control circuit, a gate driving circuit and a source driving circuit. The source driving circuit includes a plurality of source driving chips, compensates for an amplifier offset in response to the gate-start pulse signal, performs digital-to-analog (D/A) conversion on data received from the control circuit using gray scale voltages in response to the source control signal, and provides the converted data to the source lines.

    IPC: G09G3/36

    Abstract: A display driver includes a first latch storing first image data, a second latch storing second image data, and a buffer unit including a plurality of output buffers outputting a source voltage corresponding to the first image data. Each of the plurality of output buffers includes an input stage, an output stage, and a pre-charge circuit connected between the input stage and the output stage. A pre-charge control unit compares the first image data with the second image data to control the pre-charge circuit.
