    摘要： With regard to a display device having an SRAM incorporated in a pixel, a technology is disclosed, which is capable of reducing manufacturing costs by simplifying a constitution of a driver. A write voltage equivalent to white or black represented by a tone level of a normal display area is converted into a write voltage corresponding to a brightest white display or a darkest black display in the pixel, and is held in the SRAM of each pixel. In the case of normal display, display is carried out with the write voltage represented by the tone level of the normal display area. In the case of static image display, display is carried out with the write voltage corresponding to the brightest white display or the darkest black display in the pixel, the write voltage being held in the SRAM. Since the normal display and the static image display can be carried out with a write voltage supplied from one driver, the constitution of the driver can be simplified.

    摘要翻译： 关于具有并入像素的SRAM的显示装置，公开了通过简化驾驶员的构成能够降低制造成本的技术。 将由正常显示区域的色调等级表示的白色或黑色的写入电压转换成与像素中的最亮的白色显示或最黑色的黑色显示对应的写入电压，并保持在每个像素的SRAM中。 在正常显示的情况下，以正常显示区域的音调电平表示的写入电压进行显示。 在静态图像显示的情况下，以对应于像素中最亮的白色显示或最黑黑色显示的写入电压进行显示，写入电压保持在SRAM中。 由于可以用从一个驾驶员提供的写入电压来执行正常显示和静态图像显示，因此可以简化驾驶员的构成。
