Electronic device and method for swapping gamma voltage for discharging of pixels

A method of an electronic device, the method comprising:

• determining whether a display including a plurality of pixels is in at least one prespecified abnormal state;
• and
• performing a display recovery operation, based on determining that the display is in the abnormal state, the display recovery operation comprising an operation of transitioning the display from an on state to an off state and an operation of transitioning the display from the off state to the on state,
• wherein the display is connected to an electroluminescent voltage drain drain (ELVDD) line to which a specified first voltage is applied and an electroluminescent voltage source source (ELVSS) line to which a specified second voltage is applied, wherein the plurality of pixels are configured to output light corresponding to a data signal input through a data line, and
• wherein, while the display is in the off state, the method further comprises:
• supplying a ground voltage to the ELVDD line and the ELVSS line, and
• controlling a device driver integrated circuit (IC) (DDI) to supply a discharge voltage for discharging a voltage of a specified node included in each of the plurality of pixels to a data line of the display before the display transitions from the off state to the on state, the discharge voltage being a voltage set to cause the plurality of pixels to display a black grayscale while the ground voltage is applied to the ELVDD line and the ELVSS line.

One or more non-transitory computer-readable storage media storing computer-executable instructions that, when executed by a processor individually or collectively, cause an electronic device to perform operations, the operations comprising:

• determining whether a display including a plurality of pixels is in at least one prespecified abnormal state;
• and
• performing a display recovery operation, based on determining that the display is in the abnormal state, the display recovery operation comprising an operation of transitioning the display from an on state to an off state and an operation of transitioning the display from the off state to the on state,
• wherein the display is connected to an electroluminescent voltage drain drain (ELVDD) line to which a specified first voltage is applied and an electroluminescent voltage source source (ELVSS) line to which a specified second voltage is applied, wherein the plurality of pixels are configured to output light corresponding to a data signal input through a data line, and
• wherein, while the display is in the off state, the operations further comprise:
• supplying a ground voltage to the ELVDD line and the ELVSS line, and
• controlling a device driver integrated circuit (IC) (DDI) is controlled to supply a discharge voltage for discharging a voltage of a specified node included in each of the plurality of pixels to a data line of the display before the display transitions from the off state to the on state, the discharge voltage being a voltage set to cause the plurality of pixels to display a black grayscale while the ground voltage is applied to the ELVDD line and the ELVSS line.
