[embodiment]
Below through concrete embodiment and combine accompanying drawing that the present invention is described in further detail.
Embodiment one:
Please refer to shown in Figure 1ly, a kind of electronic installation of this example specifically can be mobile phone, PDA or panel computer, comprising:
Master controller is used for coordinating control electromagnetic touch screen, display screen etc.;
The electromagnetic touch screen comprises electromagnetic induction antenna, electromagnetic induction control module; Time writer is during near the electromagnetic induction antenna, and the electromagnetic induction antenna produces induced signal, is obtained by the electromagnetic induction control module, and the electromagnetic induction control module is transferred to master controller after carrying out signal Processing;
Display screen;
Operational module according to the instruction of master controller, carries out to electronic installation that screen wakes up and carry out release; Or the electronic installation that directly screen is waken up carries out release, but makes electronic installation get into normal operating state.In another embodiment, operational module also can be the sub-module in the master controller.
Input tool: adopt and the supporting time writer of electromagnetic touch screen.
Embodiment two:
In conjunction with the electronic installation among the embodiment one, have the electromagnetic touch screen as man-machine interface, specifically can be mobile phone, PDA or dull and stereotyped electroplax, under lock-out state, when using, the user must carry out unlocking operation.
Please refer to shown in Figure 2ly, under the prerequisite that display screen and electromagnetic touch screen has been waken up, or display screen shields with electromagnetic touch and is under the normal mode of operation; Such as; Be in the electronic installation of park mode, after being triggered by power button, master controller gets into normal mode of operation; And send to display screen and to wake instruction up; Display screen is waken up to be lighted, and the electromagnetic touch screen recovers normal scan mode, produces a look-at-me when above-mentioned power button triggers and delivers to master controller.The unlock method that is used for electronic installation of this example comprises the steps:
The electromagnetic signal of electromagnetic touch screen sensing time writer:
Electromagnetic signal by the electromagnetic induction antenna sensing time writer of electromagnetic touch screen;
When the electromagnetic induction antenna senses time writer near to detection-sensitive distance the time, produce induced signal; Detection-sensitive distance is relevant with power, the time writer emissive power of electromagnetic induction antenna; In this example; Effectively detection-sensitive distance is chosen as 15 millimeters, and when promptly time writer shielded to 15 millimeters altitude range near electromagnetic touch, the electromagnetic induction antenna can sense the electromagnetic signal of time writer; And the generation induced signal, this induced signal sends master controller to through the electromagnetic induction control module of electromagnetic touch screen.
The electromagnetic induction control module is transferred to master controller after obtaining induced signal and carrying out signal Processing;
Master controller sends unlock command to operational module;
Operational module is according to the unlock command release.
The unlock method that this is routine by the induced signal of time writer near touch-screen, just can anticipation be gone out the intention that the user uses electronic installation at screen before clicking, and directly carries out unlocking operation; So, can respond user's use intention in advance, in the process of time writer, realize the screen release near, some touch screen curtain; This release mode is simple and fast very; The user can not aware unlocking process, more need not remember release mode or password etc. specially, avoids occurring the inconvenience of forgetting that release mode or password etc. bring to the user.
Embodiment three:
Please refer to shown in Figure 3; A kind of electronic installation of this example is under holding state, when display screen is closed; Master controller possibly be in the wherein a kind of of two kinds of patterns: park mode or park mode not, these two kinds of mode of operations can guarantee that the electromagnetic touch screen senses time writer.
In general; When master controller was in park mode, display screen was not lighted, and the electromagnetic touch screen is under the low-velocity scanning pattern; Can sensing time writer whether near; But can not respond operations such as time writer handwriting input, concrete processing, respond the operations such as handwriting input of this time writer, need wake master controller up and handle.In this case, master controller can send a look-at-me by electromagnetic touch screen and interrupts the dormancy of master controller; Also can directly send a look-at-me by time writer gives master controller to interrupt the dormancy of master controller.After master controller was waken up, that can control display screen lights, obtains induced signal and handle time writer write operation such as input.
The unlock method that is used for electronic installation of this example comprises the steps:
The electromagnetic signal of electromagnetic touch screen sensing time writer:
Electromagnetic signal by the electromagnetic induction antenna sensing time writer of electromagnetic touch screen;
When the electromagnetic induction antenna senses time writer near to detection-sensitive distance the time, produce induced signal;
The electromagnetic induction control module is transferred to master controller after obtaining induced signal and carrying out signal Processing;
Master controller sends unlock command to operational module, and master controller sends to display screen and wakes instruction up simultaneously;
Display screen is waken up to be lighted, and operational module is according to the unlock command release simultaneously.
The unlock method that this is routine by the induced signal of time writer near touch-screen, just can anticipation be gone out the intention that the user uses electronic installation at screen before clicking, and directly carries out unlocking operation; So, can respond user's use intention in advance, in the process of time writer, realize that simultaneously screen wakes up and release near, some touch screen curtain; This release mode is than embodiment two simple and fast more; The user can not aware unlocking process, more need not remember release mode or password etc. specially, avoids occurring the inconvenience of forgetting that release mode or password etc. bring to the user.
Among the present invention, said time writer includes but not limited to passive electrical magnetic pen and active time writer, and for the passive electrical magnetic pen, near the electromagnetic induction antenna time, the electromagnetic induction antenna promptly produces induced signal; For active time writer; Near the electromagnetic induction antenna time; Also need trigger active time writer makes it send electromagnetic signal; The electromagnetic induction antenna detection produces induced signal during to electromagnetic signal, and generally speaking, the electromagnetic signal that the electromagnetic induction antenna detection is sent to active time writer also must be in certain distance range.In a word, above-mentioned can be regarded as: the electromagnetic induction antenna all has sensing function to passive electrical magnetic pen and active time writer.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
