Systems and methods for liquid crystal display column inversion using 2-column demultiplexers

摘要

Systems, methods, and devices for performing column inversion using 2-column demultiplexers are provided. In one example, an electronic display may include a display panel with columns of pixels configured to be programmed with frames of image data and display driver circuitry. The display driver circuitry may include three demultiplexers, each respectively coupled to one pixel column of a first superpixel and one pixel column of a second superpixel. Each of the three demultiplexers may receive amplified image data of a single polarity per frame.

主权项

1. An electronic display comprising:
a display panel comprising columns of pixels configured to be programmed with frames of image data, wherein the columns of pixels are grouped into superpixel columns that each comprise a plurality of pixel columns, wherein the plurality of pixel columns of each superpixel column comprises at least a first pixel column of a first color, a second pixel column of a second color, and a third pixel column of a third color; display driver circuitry comprising:
a first demultiplexer coupled to a first pixel column of a first superpixel column and a first pixel column of a second superpixel column;a second demultiplexer coupled to a second pixel column of the first superpixel column and a second pixel column of the second superpixel column;a third demultiplexer coupled to a third pixel column of the first superpixel column and a third pixel column of the third superpixel column;wherein each of the three demultiplexers is configured to receive amplified image data of a single polarity per frame; and
three source amplifiers configured to amplify image data associated with the first and second superpixel columns, wherein each source amplifier is respectively configured to couple to one of the three demultiplexers per frame and wherein one of the three source amplifiers amplifies data at a first polarity and the other two source amplifiers amplify data at a second polarity opposite the first polarity; andswitches configured to periodically vary which source amplifier couples to which demultiplexer, such that each demultiplexer receives image data of the first polarity an average of once every three frames.
