Description

Energy-saving mobile phone
[technical field]
The invention relates to a kind of energy-conservation portable electronic equipment, particularly about a kind of energy-saving mobile phone that utilizes external light source as backlight.
[background technology]
Fast development along with mechanics of communication, portable electronic equipment such as mobile phone etc. make things convenient for advantage such as fashion to become the main tool that current information is transmitted with it, function also constantly updates, display screen presents increasing trend, the display screen pigment upgrades to 260,000 looks even higher level, camera function marches on towards millions of pixel scale, and high tone quality the tinkle of bells, recreation, video playback etc. are used rapidly and popularized, and the function of mobile phone from strength to strength.So, the realization of above-mentioned each function all needs enough electric energy supports, and the battery life cycle that therefore prolongs mobile phone seems particularly important.
The method that prolongs the battery of mobile telephone life cycle at present reaches two angles of the required energy content of battery that expends of operation method that each function of mobile phone is carried out in reduction as far as possible from the improvement of the energy content of battery mostly.No matter and general mobile phone day or night, whether bright and clear, the mobile phone incoming call, breathe out when particularly the button of mobile phone is subjected to touching, when playing mobile phone, the backlight of the display screen of mobile phone and button all can be activated as the user, a large amount of electric energy of its meeting consuming cells.And the development of battery of mobile telephone also lags behind the development of function of cellular phone, if use the multiple function of mobile phone simultaneously, the stand-by time of mobile phone will be shorter, and it is illusory to cause the bigger function of some power consumption to become, and directly influences the use of the various functions of mobile phone.
A kind of prior art provides a kind of method of saving the mobile phone electric energy, it is by being provided with a Photoinduction device, obtain light degree of strength under the mobile phone environment of living in and regulate the background light brightness of display screen of mobile telephone automatically, if light is enough strong, then turn down background light brightness or close background light brightness, if light is strong inadequately, then heighten background light brightness.This technology reduces consumption to the energy content of battery by the electric flux that reduces display screen of mobile telephone and button background light and consumed as far as possible.But show the color screen mobile phone of bright-coloured color for needs, turn down the colour vividness that background light brightness meeting influences picture.
Another kind of prior art provides a kind of energy-saving mobile phone, and this energy-saving mobile phone is equipped with that a light-sensitive element is used for induction light intensity and a photoelectric control switch is used to control mobile phone at the different light intensity environment
Whether the background light of following display screen and button is opened, in display screen bottom or mobile phone top one luminous energy receiver is installed in addition, is utilized luminous energy to make accessory power supply, power to mobile phone on the one hand, to the battery of mobile telephone charging, reach energy-conservation purpose on the other hand.Whether the background light under the light-sensitive element of this technology and the photoinduction switch control different light intensity environment is opened, and the problem of existence is identical with above-mentioned first reference technique.It utilizes luminous energy to provide the mobile phone electric energy as accessory power supply, and to mobile phone charging, but battery of mobile telephone charges when electric energy does not run out of, and can shorten battery of mobile telephone useful life and reduce the highest available electrical energy capacity of battery of mobile telephone.
Be with, provide that a kind of energy-saving mobile phone that can utilize external light source is real to be necessity.
[summary of the invention]
In view of above content, be necessary to provide a kind of energy-saving mobile phone, it can receive external light source, provides to display screen of mobile telephone to show required backlight.
A kind of energy-saving mobile phone, it comprises that a main body, shows module, a module backlight, a light harvesting module and a control die set, show that module is rotatably mounted in a surface of described main body, this demonstration module comprises state and the operation message of a LCDs in order to show mobile phone, module backlight is installed on the described main body, shows that this module backlight was corresponding with the position that shows module when module overlapped with main body; One light harvesting module is rotatably mounted in another surface of described main body with respect to described demonstration module, and it comprises that a beam condensing unit is in order to gather extraneous light; When this light harvesting module is outwarded winding with the relative main body of demonstration module and is kept relative position; This control die set is closed module backlight.
Described energy-saving mobile phone utilizes Rotation Design, can will show under the well-lighted environment in the external world that module and light harvesting module screw out, beam condensing unit by the light harvesting module gathers extraneous light and offers and show the required backlight of module displays, thereby can close the module backlight of mobile phone, and then reduce the battery of mobile telephone energy consumption.
