    Abstract: A pixel circuit, a display apparatus, and a driving method. The pixel circuit include: a driving circuit, a data writing circuit, a compensation circuit, a light emission control circuit, a first reset circuit, a second reset circuit, and a light-emitting element. The data writing circuit is for writing a data signal into the first terminal of the driving circuit based on a writing control signal; the first reset circuit is for applying a first reset voltage to the control terminal of the driving circuit based on a first reset control signal; and the second reset circuit is for applying a second reset voltage to a first electrode of the light-emitting element based on a second reset control signal. The writing control signal and the second reset control signal are synchronized in each write frame, and the writing control signal remains at an invalid level in each skip frame.

    Abstract: A display substrate includes first and second display regions, and a base substrate. A plurality of sub-pixels are arranged on a side of the base substrate, where the-sub-pixels include a first pixel driving circuit and a first light-emitting device connected to each other in the first display region, and the first pixel driving circuit includes at least a compensation transistor, a switching transistor, and a light-emitting device initialization transistor each having an active layer. A scan signal line is provided in the first display region. An orthographic projection of the scan signal line on the base substrate overlaps with that of the active layer of each of the compensation transistor and the light-emitting device initialization transistor, or that of the active layer of each of the switching transistor and the light-emitting device initialization transistor on the base substrate.

    Abstract: The display substrate includes a base substrate and a plurality of pixel units disposed on the base substrate. Each of the pixel units is composed of 5 sub-pixels. The 5 sub-pixels include 1 red sub-pixel, 2 green sub-pixels, 1 blue sub-pixel and 1 white sub-pixel. Each of the sub-pixels includes a white light emitting unit. The red sub-pixel, the green sub-pixels and the blue sub-pixel further include color film layers corresponding to respective light emitting colors of the red sub-pixel, the green sub-pixels and the blue sub-pixel. The white sub-pixel is adjacent to the blue sub-pixel, and an aperture area of the blue sub-pixel is smaller than that of the green sub-pixels and smaller than that of the red sub-pixel.
