Abstract: A display apparatus includes a plurality of pixels configured to display an image, wherein the plurality of pixels is configured to be driven through a plurality of signals according to an initialization period, a programming period, a sampling period, and an emission period. The signals include a first scan signal having a high level in the initialization period and the sampling period, and having a low level in the programming period and the emission period; a second scan signal having a high level in the programming period and the sampling period, and having a low level in the initialization period and the emission period; and a voltage of a first electrode being dropped in synchronization with a falling time of the first scan signal of the initialization period.
