Abstract
An electronic device with a novel structure is provided. The electronic device includes a display apparatus, a gaze detection portion, and an arithmetic portion. The display apparatus includes a display portion divided into a plurality of sub-display portions and a functional circuit including a luminance conversion circuit. The gaze detection portion has a function of detecting the user's gaze. The arithmetic portion has a function of allocating the plurality of sub-display portions to a first section or a second section with the use of the detection result of the gaze detection portion. The functional circuit has a function of performing display on the sub-display portion included in the first section with a first driving frequency and performing display on the sub-display portion included in the second section with a second driving frequency lower than the first driving frequency. The luminance conversion circuit has a function of converting image data displayed on the second section to image data with reduced luminance to be displayed in the sub-display portion.
