Display device
First Claim
1. A display device comprising:
- a display portion; and
a scan line driver circuit electrically connected to the display portion,wherein a clock signal is supplied to the scan line driver circuit,wherein the display portion is configured such that a first image is displayed in a first display region while a second image is displayed in a second display region,wherein the first image and the second image are different,wherein the display portion is configured such that input is performed by touching the second image, andwherein one frame period comprises a period during which supply of the clock signal and a start pulse signal are not input to the scan line driver circuit while the second image is not updated.

Abstract
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.
