Abstract
The elimination of crosstalk between data lines and pixel cells in a thin film transistor/liquid crystal display is accomplished by applying a precharge voltage level for a given data signal level which also provides an equivalent to a compensation voltage for a prior scan line to a given data line for a time period less than the standard scan line period of the display, and applying the data signal to the given data line for the remainder of the scan line period.
