Abstract:
A liquid crystal display having a liquid crystal display driver that drives transistors through plural source lines on a substrate in which transistors and pixel electrodes are disposed in a matrix, said liquid crystal display driver comprising:a shift register for inputting a clock signal;a data register for receiving data from said shift register, and inputting display data of red, green and blue and an output power control signal for each red, green and blue signal of said display data, said output power control signal designating amended source lines;a latch for receiving data from said data register and inputting a strobe signal;a digital to analog converter which receives data from said latch, inputs said strobe signal, and converts said data from said latch to analog data; andan output amplifier having plural output circuits and receiving said analog data and outputting signals to said plural source lines respectively,wherein in said operational amplifier, said output power control signals alter said output signals to said amended source lines so that said output signals to said amended source lines have power levels that differ from those of said output signals to non-amended source lines.
