Abstract
A display device capable of performing image processing is provided. A memory node is provided in each pixel included in the display device. An intended correction data is held in the memory node. The correction data is calculated by an external device and written into each pixel. The correction data is added to image data by capacitive coupling, and the resulting data is supplied to a display element. Thus, the display element can display a corrected image. The correction enables image upconversion, for example.
Claims4
A display device comprising:
- a first pixel electrically connected to a first signal line and a first gate line;
- a second pixel electrically connected to a second signal line and the first gate line;
- a third pixel electrically connected to the first signal line and a second gate line;
- a first switch between the first signal line and the second signal line;
- and
- a second switch between the first gate line and the second gate line,
- wherein the first signal line and the second signal line are electrically connected by the first switch,
- wherein the first gate line and the second gate line are electrically connected by the second switch,
- wherein the first pixel and the second pixel are in the same row, and
- wherein the first pixel and the third pixel are in the same column.
