Abstract: A display panel includes a display area (DA) and a peripheral area (PA) surrounding the display area (DA). The display area (DA) includes a second area and a first area that includes first pixel units disposed around holes, where the second area includes second pixel units and K data lines. The second pixel units include M columns*N rows of light emitting devices, M*N bottom drive circuits located at lower layers of the light emitting devices, and M*N anode leads connecting the light emitting devices to the bottom drive circuits. Intervals between some or all of the adjacent light emitting devices are greater than dimensions of the bottom drive circuits corresponding to the light emitting devices, and therefore there are gaps between the some or all of the second pixel units.

Abstract: This application discloses a display control apparatus, a display apparatus, and an electronic device, relates to the field of electronic circuit technologies. A specific solution is as follows. An adjustment unit in the display control apparatus outputs an adjustment voltage in a write frame to a control-end back channel of a drive thin-film transistor in a light-emitting drive unit, so that the influence of negative bias of a threshold voltage of the drive thin-film transistor caused by a negative voltage of a first reset voltage, and therefore a transfer characteristic curve of the drive thin-film transistor shifts forward in the write frame, that is, the threshold voltage of the drive thin-film transistor shifts forward, making it easier for the drive thin-film transistor to turn on in the write frame, and increasing the brightness of the drive thin-film transistor in the write frame.
