Abstract
The present invention relates to an electricity saving apparatus for lighting display screens of mobile phones and lighting keyboards. A photosensitive induction device for detecting the strength of outside light rays a mobile phone and controlling whether a lighting device of a liquid crystal display screen and a lighting device of a keyboard are started and lightened or not is arranged on the mobile phone, and whether the photosensitive induction device is communicated with lighting control circuits of the display screen and the keyboard or not is determined by the strength of the outside light rays. The use method of the apparatus comprises the steps: when the mobile phone is charged and is in the stand-by state, whether the lighting of the outside light rays is sufficient or not is judged by the photosensitive induction device to determine whether the lighting devices of the liquid crystal display screen and the keyboard are started and lightened or not when different trigger actions, such as reception of incoming call signals, keyboard input, etc., occur.
Description
Technical field
The present invention relates to the lighting device on a kind of telephone set, exactly, relate to the using method of the saving electricity saver of LCDs illumination on a kind of mobile phone and keyboard illumination.
Background technology
Enter the nineties, mobile communication obtains the development of advancing by leaps and bounds.Digitlization, individualized, miniaturization have also been moved towards in the mobile communication development of China, have caught up with international most advanced level.The present mobile phone that uses, display screen on it normally adopts the plane LCD panel to constitute, because LCD panel itself is not luminous, so the both sides of the LCDs in mobile phone or all around all are installed on a plurality of light-emitting diodes tubing illuminating devices.When as long as in a single day this mobile phone receives incoming telephone signal or keyboard input, preparation conversation is arranged, the light power of its place environment no matter, the illuminating device of the LCD panel in the mobile phone will power up connection immediately and send light, sees content displayed on the liquid crystal panel clearly with convenient user.Yet when the light of external environment is strong, for example in the daytime or lighting during very bright night, the illuminating device of its LCDs can not power up fully because the illumination power consumption of display screen up to tens of milliampere to nearly hundred milliamperes, this moment, the power supply waste of mobile phone was appreciable.Equally, the luminescent device in the mobile phone keyboard equally also exists the problem of not lighting illumination according to external environment light power automatically.
Summary of the invention
The purpose of this invention is to provide the using method of the electricity saver of a kind of display screen illumination of mobile phone and keyboard illumination, thereby can effectively save the power supply of mobile phone, to prolong its standby and air time.
The object of the present invention is achieved like this: the using method of a kind of display screen illumination of mobile phone and the electricity saver of keyboard illumination is characterized in that: include the following step:
(1) when mobile phone powers up standby, detects by the photo sensor device on it earlier and judge whether extraneous light illumination is sufficient, and promptly whether light illumination reaches a threshold value of determining;
(2) judge extraneous light sufficiency of illumination as photo sensor device, promptly light illumination reaches a threshold value of determining, the illuminating device of then do not start light LCDs illuminating device and keyboard;
(3) judge extraneous light illumination deficiency as photo sensor device, be that light illumination does not reach a threshold value of determining, judge further then whether this mobile phone has the incoming telephone signal of reception or keyboard to import or patch charger, push-and-pull slip lid, open or close and renovate, regulate exterior volume key and the generation of other trigger actions; If have, this photo sensor device illuminating device of LCDs illuminating device and keyboard that will start light then, otherwise, the illuminating device of still do not start light LCDs illuminating device and keyboard;
(4) enter the further work state of mobile phone.
Characteristics of the present invention are earlier by being arranged on LCDs, keyboard, casing, the photo resistance at antenna or other positions of mobile phone shell, photodiode, phototriode class photo sensor device detects the power of its extraneous light illumination, so that receiving incoming telephone signal, or keyboard input, or patch charger, the push-and-pull slip lid, open or close and renovate, when regulating the trigger action generation of exterior volume key and other preparation conversations, whether start light by the resistance state decision keyboard illumination of this photo resistance and the background lighting installation of LCDs, perhaps by photodiode, the output of phototriode class photo sensor device determines the control circuit of the illuminating device of whether cut-in point brightness liquid crystal display screen illumination and keyboard, thereby can significantly save the electrical source consumption of mobile phone, prolong its standby and air time.And this photo sensor device can be photo resistance, photodiode, phototriode class individual devices, also can be to make incorporate microelectronic component with LCD panel or keyboard or casing or antenna.
Description of drawings
Fig. 1 is an electricity saver of the present invention installation site schematic diagram.
Fig. 2 is an electricity saver using method program flow diagram of the present invention.
Embodiment
Referring to Fig. 1, electricity saver of the present invention is install one and detects extraneous light power and control the LCDs illuminating device and whether the keyboard illumination device starts light photo sensor device 3 on the shell optional position of mobile phone 1, determine by the power of extraneous light whether this photo sensor device can connect the illumination control circuit of display screen and keyboard.This photo sensor device 3 can be photo resistance, photodiode, phototriode class photo sensor device, also can be the photo sensor device of other kinds.This photo sensor device 3 can be an individual devices, is placed in a side (as shown in Figure 1) of the LCDs 2 of mobile phone, perhaps is installed on the optional position of shell of keyboard 4 or casing 5 or antenna or mobile phone; Both can be the microelectronic component of making one with LCD panel 2, also can be to make incorporate microelectronic component with keyboard 4 or casing 5 or antenna.
Referring to the program flow diagram of electricity saver using method of the present invention shown in Figure 2, the step of the using method of electricity saver of the present invention is such:
1, whether when mobile phone powers up standby, it is sufficient to detect the illumination of judging extraneous light by the photo sensor device on it earlier, and promptly whether light illumination reaches a threshold value of determining.
2, judge extraneous light sufficiency of illumination as photo sensor device, promptly light illumination reaches a threshold value of determining, the illuminating device of then do not start light LCDs illuminating device and keyboard.
3, judge extraneous light illumination deficiency as photo sensor device, be that light illumination does not reach a threshold value of determining, judge further then whether this mobile phone has reception incoming telephone signal or keyboard input or the trigger action of renovating, regulate exterior volume key and other preparation conversations that patches charger, push-and-pull slip lid, opens or close takes place, if have, this photo sensor device illuminating device of LCDs illuminating device and keyboard that will start light then, otherwise, the illuminating device of still do not start light LCDs illuminating device and keyboard.
4, enter the further work state of mobile phone.
