Abstract
Systems, methods, and devices for column inversion are provided. In one example, an electronic display may include a display panel having columns of pixels and display driver circuitry. The display driver circuitry may include source amplifiers and demultiplexers. Each demultiplexer may channel data output by at least one source amplifier to one of three columns of pixels. The display driver circuitry may drive the display panel according to a 3-column inversion scheme using one source amplifier per demultiplexer per frame of image data.
