Local screen brightening method and local screen brightening device for terminal screen and terminal

Abstract

The invention provides a local screen brightening method and local screen brightening device for a terminal screen and a terminal.The local screen brightening method for the terminal screen comprises the steps that when the terminal is in a screen darkening state, a fingerprint collecting instruction is received, and current fingerprint information of a user is collected; target fingerprint information matched with the current fingerprint information is acquired from multiple preset fingerprint information; a screen subregion corresponding to the target fingerprint information is controlled to be brightened.According to the local screen brightening method and local screen brightening device for the terminal screen and the terminal, when the terminal in the screen darkening state is operated, energy conservation of the terminal can be achieved, and then the duration capacity of the terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, and in particular, to a method for partially brightening a screen of a terminal, a device for partially brightening a screen of a terminal, and a terminal. Background technique [0002] At present, with the development of the times and the improvement of people's material living standards, terminals (eg, mobile phones) have become an indispensable tool in people's lives. However, the endurance of the terminal battery has always been a pain point in the user experience, and it is a bottleneck technology to be broken through in the terminal research and development. Existing terminal energy-saving solutions include: [0003] (1) Lower CPU main frequency: reduce the main frequency of the CPU through the terminal cleaning tool, thereby reducing power consumption and achieving energy-saving battery life; its defect: it will clean up many processes and background programs. [0004] (2) Redu...

AI Technical Summary

Problems solved by technology

[0003] (1) Reduce the main frequency of the CPU: use the terminal cleaning tool to reduce the main frequency of the CPU, thereby reducing power consumption and realizing energy saving and battery life; its defect: it will clean up many processes and many background programs

[0004] (2) Reduce the brightness of the screen: the screen is the most power-consuming device, and energy can be saved by reducing the brightness of the screen; its defect: it will affect the user's visual experience

[0005] (3) Disconnect from the network, clean up background programs, etc.; its defect: it will limit the user's use of functions

[0006] The energy-saving solutions for the above three terminals need to be carried out on the premise that the terminal screen is on, and cannot be operated when the screen is off.
