Abstract
A display apparatus with reduced power consumption is provided. The display apparatus includes a display portion including a first region and a second region, a first driver circuit corresponding to the first region, a second driver circuit corresponding to the second region, a first circuit, a second circuit, a first signal generation circuit, and a second signal generation circuit. The first circuit has a function of generating a first image signal corresponding to a first image, and the second circuit has a function of generating a second image signal corresponding to a second image. The second image contains character information. The first signal generation circuit has a function of generating a clock signal with a first frame frequency, and the second signal generation circuit has a function of generating a clock signal with a second frame frequency lower than the first frame frequency. The display apparatus displays the first image on the first region with the first frame frequency when the first image signal is transmitted to the first driver circuit, and displays the second image on the second region with the second frame frequency when the second image signal is transmitted to the second driver circuit.
