    摘要: A display apparatus includes: a pixel part including a plurality of pixels, each of the plurality of pixels to receive a first scan signal and an emission signal; and a scan driver to output the first scan signal and the emission signal to each of the plurality of pixels. In a second driving mode in which the display apparatus is driven with a first driving frequency lower than a maximum driving frequency, the scan driver is to supply the first scan signal to the plurality of pixels according to the first driving frequency, and supply the emission signal to the plurality of pixels according to the maximum driving frequency.
