One of feature of the present invention, is before opening display, and Schilling electronic installation updates the content of display, renewal Just opening display after finishing, user is allowed just to obtain the message that renewal finishes in the First view for seeing display.
It refer to shown in Fig. 2, it is the block schematic diagram of the electronic installation 200 of the embodiment of this case one.Electronic installation 200 can With the graphics processing unit 220 comprising a display 210, for connecting the display 210, for performing an operating system One processing module 230, the memory module 240 for useing system storage as, a storage module 250 and an input module 260。
The electronic installation 200 can be the mobile device or use of tablet personal computer and mobile phone etc using battery Civil power continues the computer system of supplying energy.Although in the embodiment shown in Figure 2, above-mentioned modules are separated, But it will be understood by those skilled in the art that arriving, above-mentioned modules can be combined.For example, it is modern Integrated chip used in mobile phone, wherein processing module 230 and graphics processing unit 220 can be contained.
The processing module 230 of the electronic installation 200 is used to perform an operating system, and master is used as by the use of memory module 240 Want operation resources.The operating system is controlled through processing module 230 to each module of electronic installation 200, at figure Manage unit 220, storage module 250 and input module 260.It will be understood by those skilled in the art that arrive, the operation system The performed system program of system or performed program under the operating system environment, can carry out according to this case embodiment Method.
Above-mentioned input module 260 can include several different input modules or its any combination.It can include one Communication module 261, a key-press module 262, a touch-control module 263 and a directive property input module 264.The input of remaining species Module 260 can also include satellite positioning module, gyro module, inertial navigation module, accelerometer module, angular accelerometer Module, photoinduction module etc..It will be understood by those skilled in the art that arriving, the present invention is impossible to exhaust miscellaneous defeated Enter module 260.Therefore, as long as the input module 260 of incoming event can be produced, the description of the present embodiment is all met.
Referring again to shown in Fig. 3, it illustrates for a flow of the method for the renewal display contents of one embodiment of the invention Figure.As it was previously stated, this method can be held as the system program performed by the operating system or under the operating system environment Capable program performs.Among step 310, either because of the instruction under user, or beyond a standby time, electronics dress 200 display 210 is put to be closed.Then among step 320, the input module 260 of electronic installation 200 receives at least One startup event.
Single individual or its arbitrary may combine of input module 260 illustrated in fig. 2 can sense some inputs Event, and then start event using these incoming events as one, for starting above-mentioned display 210.For example satellite fix Module and gyro module can be by the above-mentioned processing modules 230 of the position informing of electronic installation 200, when position changes more than one When determining scope, a startup event can be triggered.Communication module 261 can be any module to be communicated outside with electronic installation 200, when When communication module 261 is connected to the signal of extraneous network, such as incoming call or news in brief etc. is received, a startup thing can also be triggered Part.Key-press module 262 can include any entity or virtual button, when be connected to user it is tactile on time, one can be triggered Startup event.Touch-control module 263 can be the touch surface more than one-dimensional, such as handwriting pad, Trackpad or touch screen etc..Together Sample, when be connected to user it is tactile on time, a startup event can be triggered.Directive property input module 264 can be slide-mouse, track Ball or light pen etc..When detecting the slider position change that directive property input module 264 is controlled, a startup thing can be triggered Part.
Many is enumerated above can be as the incoming event of startup event, many input modules with producing incoming event. Although these startup events all may cause electronic installation to must start up display 210, and make user observe display 210 On content, but the property of not all startup event is all identical.The property of startup event referred herein, which can include, to be made Whether information content number, the corresponding data of startup event are complete at any time accordingly for the urgency of user's response, the event institute of startup Etc. factor.
For example, when communication module 261 is connected to the telephone ring signal of outside, this enabling signal represents user Need the response of immediacy.The corresponding information content of telephone ring signal institute generally only one group of incoming phone number, and this group is come Electric telephone number is complete when receiving bell signal.Therefore, when the startup for being connected to this type of external call bell signal During event, the method shown in prior art can be continued to use, the method shown in the embodiment of the present invention can also be used.
In another example, if electronic installation 200 is connected to the startup event of key-press module 262, represent under user Make opening display 210.When the startup event for running into this type, user, which does not represent, to be wanted to see display 210 The urgency of content.And electronic installation 200 is not aware that the startup event of the type accordingly arrives some customizing messages, that is with regard to generation Table user and any part of display contents all may be interested in.Compared with single group of caller ID, it is whole aobvious Show that the data volume of device content is much greater.Assume again before step 310 closes display, stock is performed under operating system environment Admission fee lattice monitoring program.But newest stock price does not have the memory module 240 or storage module in electronic installation 200 Within 250, so the corresponding data of the event of startup institute are not complete.Among this example, due to the startup event of this type The response immediately of user is not required for, required data volume is larger, and required data are not complete in electronic installation Within 200, so being especially suitable for using the embodiment shown in this case.
Therefore the flow shown in Fig. 3, after step 320 receives startup event, an optional step 330 can be performed, Judge the type of startup event.If the type of the startup event is adapted to be handled with this case, step 340 is then performed; Otherwise, can be carried out according to the flow shown in prior art.It will be understood by those skilled in the art that arriving, judge previously Start the description of event type, enumerate three Considerations.However, start the judgement of event type, it may be considered that these three Factor or any combination along with other factors.Flow shown in Fig. 3 can select not performing judgment step 330, be connected to and open After dynamic event, follow-up step is then performed without exception.
Among an embodiment of optional step 340, it can start to ignore the startup event subsequently received.Input module 260, which may be connected to more than one, starts event, so only needing a startup event, it is not necessary to waste computing resource again Go to receive startup event, follow-up startup event will not also interfere original flow.Certainly, the embodiment shown in this case Step 340 can also be skipped over.Among another embodiment of step 340, input module 260 receive one start event it Afterwards, will stop receiving follow-up startup event.Both embodiments can save the computing resource or electric power of input module, and And the startup event of isolation subsequently is to the interference caused by flow.
After optional step 340, flow can perform another optional step 350.Among step 350, meeting Operating system or corresponding individual modules are made to switch to normal mode by battery saving mode.For example, the phone being in the previously mentioned comes Among the example of electricity, if the action of incoming call answering needs the normal work of touch-control module 263, then touch-control module must be made 263 are switched to normal mode by battery saving mode.And the processing module 230 of electronic installation 200 is controlled also to be obtained with operating system by saving Power mode is switched to normal mode.Exemplified by lifting previous stock price monitoring program again, because stock price monitoring program needs Newest program is obtained through the networking of communication module 261, it is therefore necessary to make communication module 261 be switched to normal mode by battery saving mode Formula.In certain embodiments, the above-mentioned module that normal mode is switched to by battery saving mode, following any combination can be included: Graphics processing unit 220, memory module 240, storage module 250 and communication module 261.When above-mentioned module is in power saving During pattern, when the processing module 230 makes the desire display content be updated, the module is switched into normal mode, makes its renewal The desire display content.But after the closing of step 310 display, but the modules of electronic installation 200 are not yet switched to province During power mode, flow can be omitted and not perform step 350 naturally.
It is connected on after optional step 350, is the step 360 having to carry out, that is, update display contents.Some In embodiment, operating system may require that each program for taking display picture is updated to the picture that it is responsible for.With elder generation Exemplified by preceding stock price monitoring program, due to which occupies picture to show newest stock price, so the program can quilt Operating system call is updated to picture.It will be understood by those skilled in the art that if display picture is multiple Shared by the form of program, then might have multiple programs and be required to update its image content.In a certain embodiment, these Image content after renewal, it will among renewal to memory module 240, be sent to again through graphics processing unit 220 at that time Display 210.In another embodiment, electronic installation 200 and may not include special graphics processing unit 220, but by Image content among memory module 240 is sent to display 210 by processing module 230.In a more embodiment, at figure Reason unit 220 is included among processing module 230, so and will be drawn by processing module 230 among memory module 240 Face content is sent to display 210.
After display picture renewal finishes, flow can perform step 370, after opening display is to show renewal Picture.As it was previously stated, in certain embodiment, graphics processing unit 220 can be the image content after renewal from memory module 240 Middle taking-up, then be sent in display 210.Accordingly, user's First view sees that the content of display 210 is exactly interior after updating Hold, whether also wait for electronic installation 200 without considering content is updated.
Last optional step 380 is corresponding to optional step 340.Assuming that if flow performs optional step 340, So just have to carry out optional step 380.If previously performed in step 340 and ignored the follow-up implementation model for starting event Example, then step 380 is so that the operating system of electronic installation 200 stops ignoring follow-up startup event.If step was previously performed Rapid 340 stopping receives the follow-up implementation example for starting event, then step 380 make it that electronic installation 200 is opened in the display After opening, follow-up startup event is continued to.Because these startup events are likely to trigger other different from starting display The action of device 210, or after display 210 starts, trigger other kinds of response.
The preferred embodiment of this case is the foregoing is only, is not limited to the claim of the present invention.It is all Other are to meet the equivalent change or modification completed under the spirit disclosed in this case, should be included in following apply for a patent Within the scope of.
