Abstract:
A control circuit, a drive device, and a display. The control circuit includes: a control unit and a detection unit. The detection unit is connected with a plurality of output voltage feedback terminals of a drive chip, and the detection unit is connected with the control unit. The detection unit is configured for providing a first voltage to the control unit when a voltage of at least one output voltage feedback terminal in the plurality of output voltage feedback terminals is detected, the first voltage being greater than a second voltage received by the control unit. The control unit is configured for controlling the drive chip to restart when the first voltage is greater than the second voltage.
