ABSTRACT:
A liquid crystal display and method of operating the display includes an array of LCD elements arranged as a plurality of rows and a plurality of columns. A respective one of a plurality of data lines is connected to a respective column of LCD elements. A column of dummy LCD elements is disposed adjacent an outermost column of the array of LCD elements, and a dummy data line is connected to the dummy LCD elements of the column of dummy LCD elements. Preferably, a respective one of the plurality of data lines extends along a side of the column of LCD elements to which it is connected, between the column of LCD elements to which it is connected and an adjacent column of LCD elements, and the dummy data line extends along a side of the column of dummy LCD elements, between the column of dummy elements and the adjacent outermost column of the array of LCD elements. Data line driving means may be provided for driving a respective one of the plurality of data lines with a respective data signal having a respective polarity, a data signal driving a respective data line having a polarity which is inverted with respect to the polarity of a data signal driving an adjacent column of LCD elements. Dummy data line driving means may be provided for driving the dummy data line with a dummy data signal which has a polarity which is inverted with respect to the polarity of the data signal driving the data line connected to the outermost column of LCD elements. The column of dummy LCD elements may be obscured from a user of the LCD.
