ELECTRONIC DEVICE AND ELECTRONIC SYSTEM |
摘要 |
One object is to provide a new electronic device which is configured so that a user can read data regardless of a location, input data by directly touching a keyboard displayed on a screen or indirectly touching the keyboard with a stylus pen or the like, and use the input data. A first transistor electrically connected to a reflective electrode and a photo sensor are included over one substrate. A touch-input button displayed on a first screen region of the display portion is displayed as a still image, and a video signal is output so that a moving image is displayed on a second screen region of the display portion. A video signal processing portion supplying different signals between the case where a still image is displayed on the display portion and the case where a moving image is displayed on the display portion is included. |
