DISPLAY SYSTEM AND ELECTRONIC DEVICE

This abstract first appeared for US patent application 18959928 titled 'DISPLAY SYSTEM AND ELECTRONIC DEVICE

Original Abstract Submitted

Provided is a display system with high display quality and high resolution. The display system includes a first layer and a display portion. The display portion is positioned in a region overlapping with the first layer. The first layer includes a semiconductor substrate containing silicon as a material, and a plurality of first transistors and a plurality of second transistors whose channel formation regions contain silicon are formed over the semiconductor substrate. The first layer includes a first circuit and a second circuit; the first circuit includes a driver circuit for driving the display portion; and the second circuit includes a memory device, a GPU, and an EL correction circuit. The display portion includes a pixel, and the pixel includes a light-emitting device containing organic EL and is electrically connected to the driver circuit. The memory device has a function of retaining image data; the GPU has a function of decoding the image data read from the memory device; and the EL correction circuit has a function of correcting light emitted from the light-emitting device.
