Abstract:
The present disclosure provides a light emitting control circuit, an array substrate and a display device, and a driving method of the light emitting control circuit. The light emitting control circuit includes: a light emitting device; a driving circuit including a driving switch device configured to drive the light emitting device to emit light when the driving switch device is turned on; a detection circuit, configured to detect whether the light emitting device is short-circuited in the detection stage of the light emitting control circuit; if the light emitting device is short-circuited, the driving switch device is turned off in the light emitting stage of the light emitting control circuit; if the light emitting device is not short-circuited, the driving switch device is turned on in the light emitting stage of the light emitting control circuit.
