Patent number: 10650750Abstract: Sub-pixel compensation is described. In at least some implementations, a computing device includes a plurality of sub-pixels within a pixel which may generate an alternating display to approximate the display of a single sub-pixel. In other implementations, a voltage is applied to sub-pixels of a color such that a voltage across a first sub-pixel is proportional to a voltage across one or more additional sub-pixels. In other implementations, a change in a voltage drop across a sub-pixel is detected, and the change is compensated for by altering a voltage of a second sub-pixel within the pixel.Type: GrantFiled: March 8, 2018Date of Patent: May 12, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Rajesh Manohar Dighde, Ying Zheng
