Abstract
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.
Claims20
A device comprising:
- a plurality of pixels including a first pixel, the first pixel including a first sub-pixel of a first color and a second sub-pixel of the first color;
- and
- a driving circuit configured to:
- receive an input signal representing a luminous intensity for the first color for the first pixel for a first duration;
- and
- in response to the received input signal and during the first duration, alternately drive the first sub-pixel and the second sub-pixel by driving the first sub-pixel for a second duration and driving the second sub-pixel for a third duration, wherein a length of the second duration is shorter than a length of the first duration and a length of the third duration is shorter than the length of the first duration.

- and
- a driving circuit configured to:
- receive an input signal voltage representing a luminous intensity for the first color for the first pixel for a first duration;
- apply the input signal voltage to the first sub-pixel;
- output a first voltage computed based on the input signal voltage and a voltage drop occurring across the first sub-pixel during the application of the input signal to the first sub-pixel;
- and
- apply the first voltage to the second sub-pixel.
A method comprising:
- receiving an input signal representing a luminous intensity for a first color for a first pixel for a first duration, the first pixel including a first sub-pixel of the first color and a second sub-pixel of the first color;
