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.
Claims24
A method of operating a display system, the method comprising:
- generating signals at a first location on a signal line of the display system;
- receiving the signals at a second location on the signal line;
- and
- determining a propagation delay effect on the signals as received at the second location with use of the received signals including determining a gain factor between the signals generated at the first location and the signals as received at the second location.

A method of operating a display system, the method comprising:
- generating signals at a first location on a signal line of the display system;
- receiving the signals at a second location on the signal line, each of the received signals at the second location received with use of time periods of different durations;
- and
- determining a propagation delay effect on the signals as received at the second location with use of the received signals.
1 more element
A display system comprising:
- a signal line;
- and
- a controller coupled to the signal line and adapted to
- control the display system to:
- generate signals at a first location on the signal line;
- and
- receive the signals at a second location on the signal line, and
- determine a propagation delay effect on the signals as received at the second location with use of the received signals including determining a gain factor between the signals generated at the first location and the signals as measured at the second location.
