    • A current driver that can control variation in the consumed current in conjunction with variation in the setting value of the driving current. The mirror current of transistors Q2-0 to Q2-7 at each of output circuits 10-1 to 10-160 keeps flowing through output terminal To1 or node N8 irrespective of the setting value of the pixel data. Also, the mirror current of transistor Q4D keeps flowing in the series circuit of transistors Q4D and Q5D irrespective of the setting value of the pixel data. Consequently, even when the setting value of the driving current varies in various ways, the current consumed in each output circuit can still be kept constant. As a result, it is possible to prevent variation in the voltage of the power supply line in conjunction with variation of the consumed current, and it is possible to reduce fluctuation in the driving current between output channels.
    • 可以控制消耗电流的变化与驱动电流的设定值的变化一起的电流驱动器。 输出电路10-1至10-160中的每一个晶体管Q 2 - 0至Q 2 - 7的镜像电流都保持流过输出端子1或节点N 8,而与像素数据的设置值无关。 此外,与像素数据的设定值无关,晶体管Q4D的反射镜电流保持流入晶体管Q 4 D和Q 5 D的串联电路。 因此,即使当驱动电流的设定值以各种方式变化时,每个输出电路中消耗的电流仍然可以保持恒定。 结果,可以防止电源线的电压随消耗电流的变化而发生变化,并且可以减小输出通道之间的驱动电流的波动。
