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.
Claims14
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.
