A NEW CROSSTALK COMPENSATION METHOD IN-LINE INVERSION TFT-LCDS

This brief presents a novel method to compensate a common electrode si gnal distortion caused by capacitive coupling between the data-lines a nd a common sheet electrode through a parasitic capacitor in TFT-LCD's . We designed a compensation circuit whose role is to give a negative feedback to the common electrode by detection of the amount of distort ion and generation of the dependent voltage source to cancel off the d istortion, By experiments, we saw that the newly designed compensation circuit greatly reduced the distortion caused by crosstalk in large s ize line inversion TFT-LCD's.
