ABSTRACT:
A method and an apparatus for driving multi-segment display device are described. According to the present invention, problems of driving the electrode wire activation mode of the conventional liquid crystal display are solved by the driving waveforms. The driving waveforms of non-display area are in the OFF mode, where the non-display area has pixels in the OFF mode, driving electrode wires and background area. Problems of driving voltage wire activation mode are decreased, cost is lowered, and processing is simplified, so that every pixel of the display device will be controlled precisely.
