发明名称 Semiconductor display device and method of driving the same
摘要 In a driving circuit of a digital gradation system semiconductor display device, one D/A conversion circuit 208 is provided for a plurality of source signal lines, and the respective source signal lines are driven in a time-division manner. By this, the number of the D/A conversion circuits 208 in the driving circuit can be decreased, and miniaturization of the semiconductor display device can be achieved.
