摘要： A display apparatus includes a display panel and an emission time control chip. The display panel has a plurality of sub-pixels, and each sub-pixel includes a light emitting device, a pixel driving circuit, and an emission time control circuit. The pixel driving circuit is configured to provide a driving signal for driving the light emitting device to emit light. The emission time control circuit is configured to connect the pixel driving circuit to the light emitting device in response to an emission control signal to control a duration of transmission of the driving signal to the light emitting device. The light emitting time control chip includes at least one output terminal. The emission time control chip is configured to transmit emission time control signals to the light emitting time control circuits of the plurality of sub-pixels through the at least one output terminal.
