1. A system for calibration of a display array having a plurality of pixel circuits, comprising:
- an error extraction system for extracting error including;
a first module for monitoring a row current in a row of the display array;
a second module for generating a reference current; and
a third module for obtaining an error between the row current and the reference current, and an error estimation system for estimating a correction parameter based on the error to adjust a data voltage applied to the display array.

Abstract
A method and system for calibrating a light emitting device display is provided. The display includes a plurality of pixel circuits, each having a light emitting device. The system for the calibration monitors current drawn from a row of the display array, and generates a correction parameter to correct brightness level of the light emitting device.

23. A method of calibration of a display array having a plurality of pixel circuits, comprising the steps of:
-
extracting error, including;
providing a reference current;
monitoring a row current in a row of the display array; and
for the row, obtaining an error between the row current and the reference current, estimating a correction parameter for the row based on the error and a total data voltages applied to the pixel circuits in the row of the display array. - View Dependent Claims (24, 25, 26)
