摘要： To provide a display device capable of displaying a plurality of images by superimposition using a plurality of memory circuits provided in a pixel. A plurality of memory circuits are provided in a pixel, and signals corresponding to images for superimposition are retained in each of the plurality of memory circuits. In the pixel, the signals corresponding to the images for superimposition are added to each of the plurality of memory circuits. The signals are added to the signals retained in the memory circuits by capacitive coupling. A display element can display an image corresponding to a signal in which a signal written to a pixel through a wiring is added to the signals retained in the plurality of memory circuits. Reduction in the amount of arithmetic processing for displaying images by superimposition can be achieved.

摘要： A display device capable of performing image processing is provided.
Each pixel is provided with a memory circuit, and desired correction data is held in the memory circuit. The correction data is calculated in an external device and written into each pixel. The correction data is added to image data owing to capacitive coupling, and the resulting data is supplied to a display element. Thus, a corrected image can be displayed with the display element. The correction enables image upconversion or can compensate for an image quality reduction due to characteristics variations of transistors included in pixels.-

摘要： 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.
