Abstract
The present invention discloses an electronic device and power saving method thereof. In an embodiment, when the electronic device operates in a power-saving mode, which means an area on a screen of the electronic device is not a currently in-focus window-based interface, the area is adjusted to have reduced backlight brightness. Thus, not only the power consumed by the screen is reduced but also user experience can be maintained. In another embodiment, when the electronic device operates in a power-saving mode, display parameters for an image shown in the currently in-focus window-based interface are changed without adversely affecting the power-saving effect, so that the currently in-focus window-based interface has higher display definition than other areas do.
