Energy-saving electronic device and energy-saving method

Abstract

The invention provides an energy-saving electronic device which comprises a backlight unit, an input unit, a storage unit and a micro-processor unit, wherein the backlight unit is used for generating the back light of the electronic device; the input unit responses the input operation of the user and generates a command signal; the storage unit is used for storing a setting archive; the setting archive defines backlight time lag closure time under various use modules; the micro-processor unit comprises a timing module and a backlight management module, wherein the timing module is used for timing; the backlight management module is used for acquiring backlight on-off state corresponding to the module and backlight time lag closure time corresponding to the module which are from the setting archive when the electronic device enters into a use module and facilitating the electronic device to be in the backlight on-off state defined by the use module. When the backlight state defined by the use module is on, the device controls the timing module to counting time. When the time accounting of the timing module reaches the backlight time lag closure time, the device controls the backlight unit to close the back light.

Description

technical field [0001] The invention provides an energy-saving electronic device and an energy-saving method. Background technique [0002] With the advancement of electronic technology, various electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly popularized, which greatly facilitates users. When the majority of users use such electronic products, they always hope that the longer the usage time, the better. In the case of a fixed battery capacity, reducing the energy consumption of electronic products has become an important means to prolong their use time. The electric energy consumed by the backlight in an electronic device such as a mobile phone accounts for a considerable proportion of the entire system. Current mobile phones all adopt the technology of automatically turning off the screen and / or key backlight to save power. When the user does not perform any operation on the mobile phone within a certain period of time, th...

AI Technical Summary

Problems solved by technology

The defect of the above-mentioned technology is that it cannot distinguish different usage modes of the mobile phone. In the usage mode that does not need to use the backlight or only needs the backlight for a short time, the same delay time is used to turn off the backlight, which will still waste battery power.
