A New Driving Method for Crosstalk Compensation in Simple-matrix LCDs

Abstract

Causes of crosstalk in simple-matrix LCDs have been analyzed from the viewpoint of drive-signal waveform distortions A new driving method has been developed to reduce these distortions In this new driving method, the “scanning-line-negative-feedback” (SNF) method, the drive signal distortion from scanning electrodes is detected and it is used to control the power supply voltage for liquid crystal operation using a negative feedback technique It has been confirmed that most of the crosstalk can be eliminated from super-twisted LCDs
