Method and electronic device for switching operating mode of display

An electronic device comprising:

• a display panel including at least one pixel including at least one light emitting diode;
• a first power regulator to supply first power to an anode of the at least one light emitting diode and to supply second power to a cathode of the at least one light emitting diode;
• a display driver integrated circuit (DDI) including a second power regulator to supply third power to the anode of the at least one light emitting diode and to supply fourth power to the cathode of the at least one light emitting diode, and electrically connected with the first power regulator;
• and
• a processor electrically connected with the first power regulator and the DDI,
• wherein the processor is configured to:
• control the first power regulator such that the display panel outputs first content based on the first power and the second power, in a first operating mode;
• control the DDI such that the display panel outputs second content different from the first content based on the third power and the fourth power, in a second operating mode;
• and
• control a short detection function of the first power regulator for a specified time to prevent a current flowing through the at least one light emitting diode from being blocked, when an operating mode is switched from the second operating mode to the first operating mode.

A method of switching an operating mode of an electronic device, the method comprising:

• supplying, by a first power regulator, first power and second power to a display panel to output first content, in a first operating mode;
• supplying, by a display driver integrated circuit (DDI), third power and fourth power to the display panel to output second content, in a second operating mode;
• maintaining a voltage value of the third power to be higher than a voltage value of the first power and maintaining a voltage value of the fourth power to be higher than a voltage value of the second power, for a specified time, when the operating mode is switched from the first operating mode to the second operating mode;
• and
• cutting off the first power and the second power when the specified time is elapsed.
