Voltage adjustment method and electronic device

A voltage adjustment method applied to an electronic device, wherein a display screen of the electronic device includes at least a first display area and a second display area, the first display area includes a first boundary area, the second display area includes a second boundary area, and the first boundary area is adjacent to the second boundary area, wherein the method comprising:

• obtaining a first target luminance value of a current display of the first display area;
• obtaining a second target luminance value of the current display of the second display area;
• determining a first voltage increment value based on the first target luminance value;
• determining a second voltage increment value based on the second target luminance value;
• adjusting, based on the first voltage increment value, an initial cathode voltage of an organic light-emitting diode (OLED) device included in the first display area, wherein after voltage adjustment, a change amount between a luminance value of the first display area and the first target luminance value falls within a specified range;
• adjusting, based on the second voltage increment value, an initial cathode voltage of an OLED device included in the second display area, wherein after voltage adjustment, a change amount between a luminance value of the second display area and the second target luminance value falls within the specified range;
• and
• if an absolute value of a difference between the first voltage increment value and the second voltage increment value is greater than a specified difference, separately performing pixel smoothing processing on the first boundary area and the second boundary area.
