Title:
SEMICONDUCTOR DEVICE, DISPLAY DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
Japanese Patent JP2017227895
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor device with low power consumption.SOLUTION: The semiconductor device includes a controller, a register, and an image processing portion. The image processing portion is configured to process an image data using a parameter. The image processing portion receives image data from a frame memory and receives a parameter from the register. The frame memory is configured to retain the image data while power supply is stopped. The register is configured to retain the parameter while the power supply is stopped. The controller is configured to control power supply to the register, power supply to the frame memory, and power supply to the image processing portion. The register includes a scan chain register. A transistor constituting the scan chain register includes an oxide semiconductor in a channel formation region.SELECTED DRAWING: Figure 3
