Abstract
An output circuit of a driver includes a plurality of output nodes, a first output buffer group and a multiplexer. The first output buffer group is configured to output data to the plurality of output nodes, wherein each output buffer in the first output buffer group is configured to output data to at least two output nodes among the plurality of output nodes. The multiplexer, coupled between the plurality of output nodes and the first output buffer group, is configured to select to couple each output buffer in the first output buffer group to one of the plurality of output nodes.
Claims8
An output circuit of a driver, configured to drive a panel through a plurality of data lines, the output circuit comprising:
- a plurality of output buffers, configured to output data to the plurality of data lines, wherein each of the plurality of output buffers is configured to output data to at least two data lines among the plurality of data lines;
- and
- a multiplexer, configured to be coupled between a second number of the plurality of data lines and a first number of the plurality of output buffers, configured to selectively couple each of the first number of the plurality of output buffers to one of the second number of the plurality of data lines at a time, wherein the first number is less than the second number;
- wherein the multiplexer comprises a plurality of switches, each coupled between the plurality of output buffers and one of the plurality of data lines, and the plurality of switches comprise a plurality of polarity swapping switches and a plurality of selection switches.
