Abstract
Official abstract text for this publication.
A method for gradually adjusting screen brightness when switching an operating system is provided. The method is used for gradually adjusting the brightness of a screen of an electronic device by a controller thereof when the electronic device is switched from to first operating system to a second operating system. First, an operating system switching signal is received. Then, a first brightness value of the first operating system is obtained. The screen brightness is gradually adjusted from the first brightness value to a predetermined second brightness value. Afterwards, the first operating system is switched to the second operating system, and the screen brightness is further adjusted from the second brightness value back to the first brightness value. Accordingly, a user can sense the switching of the operating system more intuitively and has enough time to get used to the change of the screen brightness and the displayed frame.
