Abstract:
A liquid crystal display comprising:a first column line driving circuit, arranged for every two column lines, for driving the column line for a larger signal than a predetermined reference voltage;a second column line driving circuit, arranged for every two column lines, for driving the column line for a smaller signal than said predetermined reference voltage;a first pair of analog switches connected between the output end of said first column line driving circuit and the two column lines;a second pair of analog switches connected between the output end of said second column line driving circuit and the two column lines; anda control circuit for open-close controlling said first and second pair of analog switches respectively so that when the output end of said first column line driving circuit is connected to one of the two column lines, the output end of said second column line driving circuit is connected to the other of the two column lines.
