Meta patents method to drive microdisplay pixels using two digital schemes
Meta has been granted a patent for a method of controlling tiny display screens, known as microdisplays. The technique splits the brightness data for each pixel into two parts, processes them with different digital methods, and then combines them to control the pixel's on-time using pulse width modulation.
In the filing’s own words
The disclosed computer-implemented method may include rendering frame data for pixel data values, converting a first part of each pixel data value using a first digital driving scheme, and converting a second part of each pixel data value using a second digital driving scheme. The method may also include displaying the frame data by driving pixels of a display using pulse width modulation based on a converted pixel value from the converted first and second portions of the pixel data value for each pixel. Various other methods, systems, and computer-readable media are also disclosed.
What exactly they claim (claim 1)
1. A method comprising: rendering frame data including a plurality of pixel data values; converting, for each of the pixel data values, a first portion of the pixel data value using a first digital driving scheme; converting, for each of the pixel data values, a second portion of the pixel data value using a second digital driving scheme; and displaying the frame data by driving a plurality of pixels of a display using pulse width modulation based on a converted pixel value comprising the converted first and second portions of the pixel data value that corresponds to each of the plurality of pixels.
