Light emitting control circuit, driving method thereof, array substrate and display device

A light emitting control circuit, comprising:

• a light emitting device;
• a driving circuit comprising a driving switch device, a first terminal of the driving switch device is connected with an anode of the light emitting device, the driving switch device is configured to drive the light emitting device to emit light when the driving switch device is turned on;
• and
• a detection circuit, one terminal of the detection circuit is connected with a control terminal of the driving switch device, and the other terminal of the detection circuit is connected with the anode of the light emitting device, the detection circuit is configured to detect whether the light emitting device is short-circuited in a detection stage of the light emitting control circuit;
• if the light emitting device is short-circuited, the driving switch device is turned off in a 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,
• wherein the detection circuit comprises:
• a first switch device, a first terminal of the first switch device is connected with the control terminal of the driving switch device, a second terminal of the first switch device is connected with a test voltage terminal;
• a difference between the test voltage provided by the test voltage terminal and the voltage on the second terminal of the driving switch device is greater than a turning-on voltage of the driving switch device;
• the first switch device is configured to be turned on in the detection stage if the light emitting device is short-circuited, or turned off in the detection stage if the light emitting device is not short-circuited;
• and
• a second switch device, a first terminal of the second switch device is connected with the control terminal of the first switch device, a control terminal of the second switch device receives a detection control signal, a second terminal of the second switch device is connected with the anode of the light emitting device;
• the second switch device is configured to be turned on in the detection stage in response to the detection control signal, and turned off in the light emitting stage in response to the detection control signal.
