Method for display image and electronic device

An electronic device, comprising:

• a display panel;
• and
• a control circuit, electrically connected to the display panel;
• wherein an operation period of the display panel comprises a detection period and a working period, during the detection period, the control circuit is configured to provide a plurality of gate testing voltages to the display panel, wherein the plurality of gate testing voltages comprise a maximum testing voltage, an operation voltage and a failure testing voltage, the maximum testing voltage is higher than the operation voltage, the operation voltage is higher than the failure testing voltage, and a time point at which the maximum testing voltage appears is earlier than a time point at which the failure testing voltage appears, and during the working period, the control circuit is configured to output at least one image signal to the display panel according to the operation voltage;
• wherein the operation voltage is a minimum gate driving voltage that a gate in the display panel is turned on normally, and the failure testing voltage is a voltage that the gate in the display panel is not turned on.
