First Claim
Patent Images
1. A method of determining a characteristic of a circuit element of a first pixel of a display device, the first pixel sharing a monitor line with a second pixel of the display device, the method comprising:
- biasing the first pixel;
biasing the second pixel to fix a current passing through the second pixel over the monitor line to a known current; and
measuring the characteristic of the circuit element of the first pixel with use of said monitor line.

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.
