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).
