TECHNICAL FIELD

The present disclosure relates generally to an electronic device and an operating method thereof.

BACKGROUND

With the progress of technology, an electronic device has various functions added thereto and can perform multiple functions. The electronic device may include a display unit. Also, the electronic device can display various screens on the display unit. Recently, the display unit can be driven by using a self light-emitting phenomenon without a separate backlight unit.

However, the above-described electronic device may be problematic in that an afterimage may be generated on the display unit. This may be because respective lifetimes of light-emitting elements of the display unit are differently reduced. As a result, in the display unit, respective brightness degrees of the light-emitting elements may become different from each other. Therefore, an afterimage may be generated in response to an object located at a fixed position on the display unit.

For example, the storage unit440may map the attribute information of the display unit430to a minimum value and a maximum value of the object display magnification, and may store the attribute information of the display unit430mapped to the minimum value and the maximum value of the object display magnification. Through this configuration, the control unit450may determine the minimum value and the maximum value of the object display magnification by using the attribute information of the display unit430. Also, the magnification variable range of the object display magnification may be defined to be from the minimum value to the maximum value inclusive. In addition, the storage unit440may map the attribute information of the display unit430to the magnification change direction of the object display magnification, and may store the attribute information of the display unit430mapped to the magnification change direction of the object display magnification. Through this configuration, the control unit450may determine the magnification change direction of the object display magnification by using the attribute information of the display unit430. For example, the magnification change direction of the object display magnification may include a reduction direction for reducing the object display magnification towards the minimum value and an increase direction for increasing the object display magnification towards the maximum value.

Then, in operation1217, the control unit450may display an object at the object display magnification having the initial value. For example, the control unit450may display the object at the object display magnification of 249%. Thereafter, the control unit450may return toFIG. 5.
