Abstract: A display apparatus includes a display drive chip and a display, and the display drive chip is configured to drive the display. A time sequence gating circuit is added to the display drive chip, and a time sequence switch circuit is added to the display. The time sequence gating circuit can provide a gating signal for the time sequence switch circuit of the display. The time sequence switch circuit may connect or disconnect a time sequence drive circuit to or from a plurality of gate lines of the display based on the gating signal.

Abstract: A processing circuit includes a load unit and a detection circuit, and a proportional relationship exists between a load value of the load unit and a load value of a first pixel line. The load value of the load unit is obtained through the detection circuit, to obtain the load value of the first pixel line. Then, based on the load value of the first pixel line, a drive current circuit is controlled to provide a corresponding drive current to the first pixel line. When the drive current enables a light-emitting diode (LED) on the first pixel line to emit light within drive time, a current value is as small as possible.
