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.
