ABSTRACT:
A liquid crystal display and a method of operating the display. A plurality of row conductors and a plurality of column conductors control pixels arranged in a matrix of rows and columns. A driver circuit applies a first data signal to first column conductors and a second data signal to second column conductors. The first and second column conductors are adjacent alternate conductors in a row direction of the matrix. The polarity of the first and second data signals are opposite to each other. Pixels in a row may be connected to the same row conductor while pixels in each column are alternately connected, respectively, to one column conductor to which the first data signal is applied and to one column conductor to which the second data signal is applied. The pixels in each row may be alternately connected respectively to one of two adjacent row conductors. The polarity of the first and second data signals is held constant for a cycle time which is substantially equal to a frame time of the liquid crystal display.
