Abstract
An electronic device includes: a OLED display including a first display area, wherein a saturation of the first display area remains constant in a first period; a display driver for driving the OLED display and changing a brightness coefficient of the first display area from a first brightness coefficient to a second brightness coefficient during the first period; an ambient light sensor under the first display area for sensing light, wherein during the first period, the ambient light sensor generates a first sensing value when the brightness coefficient of the first display area is the first brightness coefficient and generates a second sensing value when the brightness coefficient of the first display area is the second brightness coefficient; and a controller for calculating an ambient light intensity according to the first brightness coefficient, the second brightness coefficient, the first sensing value and the second sensing value.
