Abstract: A semiconductor device includes a display device and a source driver. Each of a plurality of pixels included in the display device is supplied with a first data potential and a second data potential included in a range of a first potential or higher to a second potential or lower. The first data potential makes the pixel display an image with a first gray level. The pixel performs calculation with the first data potential and the second data potential to generate a third data potential. The third data potential makes the pixel display an image with a second gray level. A reference potential of the first data potential is an intermediate potential between the first potential and the second potential, and the gray level width that can be displayed by the second data potential is larger than the gray level width that can be displayed by the first data potential.

Abstract: Provided is an electronic device with high portability and/or high browsability. The electronic device includes first and second support bodies, a first hinge, and a flexible display panel. The first hinge has a first rotation axis and connects the first and second support bodies to each other, and the first and second support bodies are capable of relatively rotating on the first rotation axis. The display panel includes at least first and second portions supported by the first and second support bodies, respectively; the first rotation axis and a first plane including the display surface overlapping with the first portion or a second plane including the display surface overlapping with the second portion are parallel to each other; and each of a distance between the first rotation axis and the first plane or the second plane is greater than zero.

Abstract: To suppress a loss of data in a semiconductor device. To provide a display device including a capacitor storing data, a display element performing display in accordance with the data, and switching elements connected to electrodes of the capacitor. In the display device, the voltage is held between the electrodes of the capacitor by turning the switching elements off; thus, the data can be stored even when supplying the power supply is stopped.
