    • A plurality of pixels, each including first and second electrodes and an electrolytic solution, are arranged. When a voltage between the first and the second electrodes increases into a precipitation critical value or more, the precipitation of electroplating starts. When the voltage decreases into a value smaller than the deposition overvoltage value, the precipitation ends. A control unit controlling the voltage between the first and second electrodes repeats a subfield operation including a first operation of selectively supplying any of first, a second voltage and third voltages to the plurality of pixels, and a second operation of collectively supplying the second voltage value to the plurality of pixels after the first operation, at least two times or more, to control the gradation of each pixel based on a timing of supplying the third voltage.
    • 布置有多个像素,每个像素包括第一和第二电极以及电解液。 当第一和第二电极之间的电压增加到降水临界值以上时,电镀的沉淀开始。 当电压降低到小于沉积过电压值的值时,降水结束。 控制第一和第二电极之间的电压的控制单元重复子场操作,其包括选择性地向多个像素提供第一,第二电压和第三电压中的任何一个的第一操作,以及共同地提供第二电压值的第二操作 在第一操作之后的多个像素中,至少两次以上,以基于提供第三电压的定时来控制每个像素的灰度。
