    • For a display device having a solar cell and a power buffer for keeping stored electric power, a display system which has a low-power drive mode, self-contained power and no need for recharging or power wiring is provided. The display system includes a solar cell using a thin-film semiconductor, a power storage element for temporarily storing the produced power, a driving circuit, a matrix display unit, a display rewrite instruction unit for inputting screen rewrite and a control circuit and starts rewriting a display when power sufficient to rewrite an image screen is stored in the solar cell. The display device having remarkable portability and no limited battery life, which controls a display mode depending on the power produced by the solar cell, can display even when power generation is low and allows self-contained power even if the storage element has a small capacity, can be obtained.
    • 对于具有用于保持存储电力的太阳能电池和电源缓冲器的显示装置,提供具有低功率驱动模式,独立电源并且不需要充电或电力布线的显示系统。 显示系统包括使用薄膜半导体的太阳能电池,用于临时存储所产生的电力的电力存储元件,驱动电路,矩阵显示单元,用于输入屏幕重写的显示重写指令单元和控制电路,并开始重写 在足够重写图像屏幕的电力时的显示器被存储在太阳能电池中。 即使在发电量低的情况下,也能够显示出依赖太阳能电池产生的功率来控制显示模式的显示便携性和电池寿命有限的显示装置,即使存储元件的容量小 , 可以获得。
