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.
Claims26
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, wherein one of said generating the signals and said receiving the signals is performed with use of a pixel circuit coupled to said signal line.
1 more element
A display system comprising:
- a signal line;
- a pixel circuit coupled to the 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,
- wherein the controller controls the display system to generate the signals or receive the signals, with use of the pixel circuit.
