摘要： A plurality of sensor pixel circuits each including two photodiodes, one accumulation node accumulating charge corresponding to an amount of light, and a read transistor having a control terminal connected to the accumulation node are arranged in a pixel region. In accordance with a clock signal, when a backlight is turned on, a transistor turns on, a current flows through the photodiode, and a potential at the accumulation node drops. When the backlight is turned off, a transistor turns on, a current flows through the photodiode, and the potential at the accumulation node rises. Sensitivity characteristics of the two photodiodes may be changed using the clock signal. The sensor pixel circuit described above is used for detecting a difference between an amount of light to be incident when the backlight is turned on and an amount of light to be incident when the backlight is turned off.

摘要： There is provided a display device capable of displaying an image that barely changes with low power consumption on the basis of video data included in a transmitted command, and there is also provided a method for driving the same. A display timing controller (31) determines every frame period whether or not an externally transmitted command includes updated video data. As a result, when it is determined that no updated video data is included, screen refreshing is paused by not reading video data stored in frame memory (36). Moreover, when it is determined that updated video data is included, the screen refreshing is performed by reading video data stored in the frame memory (36).
摘要翻译：提供了一种显示装置，其能够基于发送的命令中包括的视频数据，以低功耗显示几乎不变化的图像，并且还提供了一种用于驱动该图像的方法。显示定时控制器（31）确定每个帧周期是否外部发送的命令包括更新的视频数据。结果，当确定不包括更新的视频数据时，通过不读取存储在帧存储器（36）中的视频数据来暂停屏幕刷新。此外，当确定包括更新的视频数据时，通过读取存储在帧存储器（36）中的视频数据来执行屏幕刷新。
