Abstract
A system for driving a display that includes a plurality of pixel circuits arranged in an array, each of the pixel circuits including a light emitting device and a driving transistor for conveying a driving current through the light emitting device. Methods of measuring characteristics of circuit elements of pixels sharing a monitor line include the control of biasing to selectively turn off circuit elements or render their response known while measuring other circuit elements of interest.
Claims14
A display comprising:
- an array of pixels including a first pixel and a second pixel;
- a monitor line coupled to the first pixel and the second pixel;
- a controller adapted to:
- bias the first pixel;
- bias at least one circuit element of the second pixel to operate in a known state;
- and
- measure a characteristic of a circuit element of the first pixel with use of said monitor line.
