CROSS-TALK REDUCTION FOR ACTIVE MATRIX DISPLAYS

摘要

An image drive data system (40) applies cross-talk compensated image drive data (CIDD) to a data line (23) for driving each pixel (21) coupled to the data line (23) to a desired optical state during an image update period inclusive of a cross-talk between the pixels (21) and the data line (23). To reduce the cross-talk, the image drive data system (40) determines cross-talk uncompensated image drive data (IDD) for driving each pixel (21) to its respective desired image exclusive of the cross-talk between the pixels (21) and the data line (23), determines a time averaged pixel data shift based on the cross-talk uncompensated image drive data (IDD) and a cross-talk coupling constant between the pixels (21) and the data line (23), and determines the cross-talk compensated drive data (CIDD) based on the time-averaged pixel data shift.
