    摘要： To provide a display device whose display can be recognized even in dark places or under the strong outside light. The display device performs display by controlling the number of gray scales in accordance with the intensity of outside light, which means a display mode can be switched in accordance with the data to be displayed on the display screen. A video signal generation circuit is controlled in each display mode in such a manner that it directly outputs an input video signal with an analog value, outputs a signal with a binary digital value, or outputs a signal with a multivalued digital value. As a result, gray scales displayed in pixels are timely changed. Accordingly, clear images can be displayed while maintaining high visibility in various environments, in the wide range from, for example, dark places or indoors (e.g., under a fluorescent lighting) to outdoors (e.g., under the sunlight).

    摘要翻译： 为了提供一种显示装置，即使在黑暗的地方或在强烈的外部光线下也能够识别显示。 显示装置通过根据外部光的强度控制灰度级数来进行显示，这意味着可以根据要在显示屏幕上显示的数据来切换显示模式。 视频信号发生电路以每个显示模式被控制，使得它直接输出具有模拟值的输入视频信号，输出具有二进制数字值的信号，或输出具有多值数字值的信号。 结果，以像素显示的灰度级是及时改变的。 因此，可以在例如暗处或室内（例如，在荧光照明下）到户外（例如，在阳光下）的广泛范围内，在各种环境中保持高可见度的同时显示清晰的图像。

    摘要： In order to increase the continuous operating time of a display device driven by a battery or the like, and a portable information terminal using the same, the volume and weight of the battery are increased. Thus, there arises a trade-off between the increased capacity of the battery and the portability of the device/terminal. Therefore, the invention provides a display device with portability ensured, which is capable of operating continuously for long periods and a portable information terminal using the same. In the display device, TFTs and an RFID tag are formed over the same insulating substrate. The RFID tag detects signals from a reader/writer, and generates DC power based on the signals. While the RFID tag is detecting signals, the display device is driven by the DC power generated in the RFID tag.
