Abstract

The invention discloses an electronic device and a power saving method thereof. In one embodiment, when the electronic device is in the power-saving mode, a screen reduces the brightness of the area except an interest window, so that a compromise can be made between the power consumption of the screen and the operation feeling of a user. In another embodiment, when the electronic device is in the power-saving mode, under the condition that the power saving effect is not influenced, an image display parameter in the interest window is changed, so that the display clearness of the interest window is higher than that of the other area.

Description

technical field [0001] The invention relates to an electronic device and a power saving method thereof, in particular to an electronic device with different display screens having different resolutions when entering a power saving mode and a power saving method thereof. Background technique [0002] At present, more and more attention is paid to energy-saving technologies and power-saving methods of electronic devices. Taking a notebook computer as an example, the notebook computer can enter a power saving mode when it is only powered by the battery. For example, reducing the operating frequency of the central processing unit, turning off the wireless communication module or reducing the brightness of the backlight of the screen, these actions are to reduce the power consumption of the notebook computer and further extend the time that the user can operate the notebook computer. However, prolonging the use time is important, but the user's operating experience cannot be ign...
