Patent Images
1. A display comprising:
- a plurality of pixel circuits;
a driver for programming the pixel circuits;
a monitor for monitoring the pixel circuits;
a signal line connecting the pixel circuits with at least one of the driver and the monitor;
a memory including propagation delay effects information for at least a subset of the pixel circuits to compensate for parasitic effects in the signal line; and
a controller capable of controlling the pixel circuit, and at least one of the driver and the monitor;
wherein the controller is capable of controlling the pixel circuit based on the propagation delay effects information stored in the memory.

Abstract
A method for characterizing and eliminating the effect of propagation delay on data and monitor lines of AMOLED panels is introduced. A similar technique may be utilized to cancel the effect of incomplete settling of select lines that control the write and read switches of pixels on a row.
