Patent ID: 7619597

Claim:
A method of real-time calibration for a display array having a plurality of pixel circuits arranged in rows and columns, the method comprising: generating a priority list of pixels, associating calibration priorities with a plurality of pixel circuits from the pixel circuits of the display array; selecting one or more pixels (n) from the priority list, the n selected pixels having the highest calibration priorities of a set of pixels in the priority list that are from a column of the display array being programmed; programming each of the n selected pixels in the column, with a respective driving voltage; monitoring a pixel current of each of the n selected pixels; determining calibration information for each of the n selected pixels based on their respective driving voltages and their monitored pixel currents; updating a compensation voltage of the n selected pixels stored in a memory based on the calibration information; and updating the priority list to associate a lowest calibration priority with each of the n selected pixels.
