Systems and methods for liquid crystal display column inversion using 3-column demultiplexers

摘要

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.

1. An electronic display comprising:
a display panel comprising columns of pixels; and display driver circuitry comprising source amplifiers and demultiplexers, each demultiplexer configured to channel data output by at least one source amplifier to one of three columns of pixels, wherein the display driver circuitry is configured to display frames of image data by driving the display panel according to a 3-column inversion scheme using one source amplifier per demultiplexer per frame of image data; wherein first and second demultiplexers are coupled to columns of pixels of two adjacent columns of superpixels, wherein each column of superpixels comprises three adjacent columns of red, green, and blue pixels, wherein: the first demultiplexer is coupled to a first column of pixels of the first column of superpixels and first and second columns of pixels of the second column of superpixels; and the second demultiplexer is coupled to second and third columns of pixels of the first column of superpixels and a third column of pixels of the second column of superpixels.
