Embodiment
Describe embodiments of the invention below in detail, the example of said embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the present invention, and can not be interpreted as limitation of the present invention.
Be illustrated in figure 1 as the portable terminal of one embodiment of the invention, this portable terminal comprises: touch-screen 1, detection module 2, close on judge module 3, conversation judge module 4 and control module 5.
Detection module 2 is used for detecting the capacitance change of the touch-screen 1 of portable terminal near the receiver part with first scanning accuracy, and wherein first scanning accuracy is greater than being used for second scanning accuracy that senses touch screen 1 is touched.Memory module 3 is used to store the predefined threshold value of closing on.Close on judge module 3 and be used for whether conductor being arranged near portable terminal, wherein predefined closing in the main frame that threshold value can be stored in portable terminal according to detection module 2 detected capacitance changes and the predefined threshold decision of closing on.Conversation judge module 4 is used for judging whether portable terminal is in conversation.Control module 5 is used for when conversation judge module 4 judges that portable terminal is in conversation, according to the backlight and/or the loud speaker of the judged result control portable terminal that closes on judge module 3.
According to the portable terminal of the embodiment of the invention only in the senses touch screen 1 near the capacitance change of receiver part, and do not scan, thereby can save sweep time full frame, make the reaction of portable terminal sensitive more.In addition; More direct than independent making infrared inductor and photo resistance device, the circuit of the portable terminal of the embodiment of the invention is simple, and cost is also lower; Can portable terminal be set according to different needs and carry out multiple function, meet user's demand more.
In one embodiment of the invention; Detection module 2 can in the touch-screen 1 of portable terminal near the transducer of receiver part; Several passages of for example under the situation of the normal use that does not influence portable terminal, choosing touch-screen 1 top carry out high accuracy scanning as detection module 2 to these several passages.Such as, the figure place of plain scan ADC is 10, and the figure place of high accuracy scan A C is 12, and discernible voltage variety is littler than plain scan, can detect the approaching of conductor more delicately.
Close on judge module 3 with detection module 2 detected capacitance changes with close on threshold value and compare, when capacitance change when closing on threshold value, judging has conductor near portable terminal; When capacitance change is not more than when closing on threshold value, judging does not have conductor near portable terminal.Then, control module 5 is controlled according to the judged result of closing on judge module 3.For example, when the user conversed, detection module 2 can detect that capacitance change increases gradually and greater than pre-set threshold, can determine the approaching of conductor (people's ear) this moment, thus the controlling back light source close, reach energy-conservation effect; Behind end of conversation, capacitance change reduces and less than pre-set threshold gradually, can judge this moment conductor (people's ear) away from, thereby open in the controlling back light source.
Be illustrated in figure 2 as the structural representation of the portable terminal of another embodiment of the present invention, this portable terminal comprises: touch-screen 1, detection module 2, close on judge module 3, conversation judge module 4 and control module 5.
Each module of the annexation of each module and effect and portable terminal shown in Figure 1 is basic identical, repeats no more here.Different is, the detection module 2 among Fig. 1 detects capacitance change always, and the detection module 2 among Fig. 2 is connected with conversation judge module 4, only when conversation judge module 4 judgement portable terminals are in the conversation, just detects capacitance change.
Describe power-economizing method in detail below in conjunction with Fig. 3 and Fig. 4 according to the portable terminal of the embodiment of the invention.
Be illustrated in figure 3 as the sketch map of power-economizing method of the portable terminal of one embodiment of the invention, the method for this embodiment may further comprise the steps:
Step S301 detects in the touch-screen of portable terminal the capacitance change near the receiver part with first scanning accuracy.
In embodiments of the present invention, first scanning accuracy is greater than being used for second scanning accuracy that senses touch screen 1 is touched.Such as, the figure place of the second scan A C is 10, and the figure place of the first scan A C is 12, and discernible like this voltage variety is littler, can detect the approaching of conductor more delicately.
Step S302 has judged whether that according to detected capacitance change conductor is near portable terminal.
Particularly, can detected capacitance change and the predefined threshold value of closing on be compared, when capacitance change when closing on threshold value, judging has conductor near portable terminal and produce closing signal; Otherwise judging does not have conductor near portable terminal, does not produce closing signal.
Step S303 judges whether portable terminal is in the conversation.
Step S304 when judging that portable terminal is in the conversation, controls the backlight and/or the loud speaker of portable terminal according to the judged result of step S302.
When having only portable terminal to be in the conversation, closing signal is just effective.If portable terminal is not in the conversation, then closing signal is not used.
Particularly, receive closing signal in the conversation again, then control the backlight of portable terminal and close when portable terminal is in; Be in the conversation when portable terminal but do not receive closing signal, then the backlight of portable terminal is not closed.
Thus, if realized when call mode, having conductor such as people's ear near the time, just carry out some function and for example close backlight, reach the effect of power saving, if during original loud speaker opens, people's ear near the time also can close hommization more automatically.
Be illustrated in figure 4 as the flow chart that closes on power-economizing method of the portable terminal of another embodiment of the present invention, the method for this embodiment may further comprise the steps:
Step S401 judges whether portable terminal is in the conversation.
Step S402 when judge that portable terminal is in the conversation, detects in the touch-screen of portable terminal the capacitance change near the receiver part with first scanning accuracy.
In the present embodiment, have only when detecting the user when carrying out call function, just high accuracy scanning closes on the module sense channel.
Step S403 has judged whether that according to capacitance change conductor is near portable terminal.
Concrete deterministic process can be identical with the description among the step S302, here for simplicity, repeats no more.
Step S404 is according to the backlight and/or the controller of the judged result of step S403 control portable terminal.
Concrete control procedure can here for simplicity, repeat no more with reference to the description of step S304.
According to the power-economizing method of the portable terminal of the embodiment of the invention only in the senses touch screen near the capacitance change of receiver part, and do not scan, thereby can save sweep time full frame, make the reaction of portable terminal sensitive more.
Although illustrated and described embodiments of the invention; For those of ordinary skill in the art; Be appreciated that under the situation that does not break away from principle of the present invention and spirit and can carry out multiple variation, modification, replacement and modification that scope of the present invention is accompanying claims and be equal to and limit to these embodiment.
