First embodiment:
Fig. 1 is the structural drawing of the electronic installation shown by first embodiment of the invention; Please refer to Fig. 1, electronic installation 100 is such as mobile phone, smart mobile phone, personal digital assistant, notebook computer, panel computer, digital camera, e-book, game machine etc., and the present invention is not limited the kind of electronic installation 100.Electronic installation 100 comprises Touch Screen 110, velocity estimated unit 120 and backlight adjusting unit 130, and its function is described below:
Touch Screen 110 is the I/O interface of electronic installation 100.Specifically, Touch Screen 110 is in order to detect the touching imposing on Touch Screen 110.For example, Touch Screen 110 can provide user's operation interface (such as, the operation screen etc. of desktop, main screen picture, application program), and user is by touching the user's operation interface be presented on Touch Screen 110, assign the operational order to electronic installation 100.Such as, user clicks or slides by pointer or finger, to pass through user's operation interface input characters or instruction on Touch Screen 110.In addition, Touch Screen 110 also can information in display electronics assemblies 100, such as, show the information content etc. that various application program produces.In the present embodiment, Touch Screen 110 can be resistance-type (resistive) Touch Screen, condenser type (capacitive) Touch Screen, optical profile type (optical) Touch Screen, sound wave type (acousticwave) Touch Screen, electromagnetic type (electromagnetic) Touch Screen etc., does not limit its kind at this.
Velocity estimated unit 120 couples Touch Screen 110, in order to judge whether the translational speed imposing on the touching of Touch Screen 110 is greater than a speed threshold value.In other words, velocity estimated unit 120 can judge that user is sliding touch screen 110 rapidly in the touching that Touch Screen 110 applies, or sliding touch screen 110 lentamente.The judged result that velocity estimated unit 120 can be obtained sends backlight adjusting unit 130 to and uses.
Backlight adjusting unit 130 couples Touch Screen 110 and velocity estimated unit 120.Backlight adjusting unit 130 in order to adjust the backlight illumination of the Touch Screen 110 of electronic installation 100, such as, is make the backlight illumination of Touch Screen 110 maintain original set value or increase/downgrade the backlight illumination of Touch Screen 110.In detail, backlight adjusting unit 130 can adjust the backlight illumination of Touch Screen 110 accordingly according to the judged result of velocity estimated unit 120.
In the present embodiment, velocity estimated unit 120 and backlight adjusting unit 130 can be the program codes write by program language or be independently chip.For example, velocity estimated unit 120 and backlight adjusting unit 130 are such as the program codes write by program language, and these program code storage are in a storage element (not shown), and performed by a processor (not shown), wherein above-mentioned storage element is such as nonvolatile memory, flash memory or hard disk etc.Or velocity estimated unit 120 and backlight adjusting unit 130 are respectively the individual chips combined by or several logic gate, and are coupled to above-mentioned processor respectively, to control above-mentioned each individual chips by this processor.
Below namely coordinate above-mentioned electronic installation 100 to each step of the method for adjustment of the backlight illumination that the embodiment of the present invention is described.Fig. 2 is the method for adjustment process flow diagram of a kind of backlight illumination shown by the embodiment of the present invention.Method of adjustment in the present embodiment, in order to adjust the backlight illumination of the Touch Screen 110 of electronic installation 100.
Must first illustrate, electronic installation 100 has non-operating state and mode of operation.Specifically, the non-operating state of electronic installation 100 comprises that Touch Screen 110 is in power down state, Touch Screen 110 is in the lock state, or electronic installation 100 is in power down state.For example, when Touch Screen 110 or electronic installation 100 are in power down state, Touch Screen 110 cannot receive the touching signals that user inputs.In addition, when Touch Screen 110 is in the lock state, Touch Screen 110 only can give a response the touching signals preset, and ignores most of touching signals that user inputs, and above-mentioned default touching signals is such as the touching signals of lock-out state about switching or remove Touch Screen 110.On the other hand, the mode of operation of electronic installation 100 is such as that user can the situation of normally operating electronic devices 100.For example, the operation of touching screen 110 energy normal reaction user, and the information in energy display electronics assemblies 100, and the operation that electronic installation 100 also can input according to user produces corresponding execution result.
Referring to Fig. 1 and Fig. 2.First, as shown in step S201, when electronic installation 100 is not in non-operating state, Touch Screen 110 detects the touching imposing on Touch Screen 110, and wherein Touch Screen 110 backlight illumination is now the first setting value.Specifically, above-mentioned touching can be the touching operation that user does on Touch Screen 110, such as, be pressing, click or slide.In addition, the backlight illumination of Touch Screen 110 can be distinguished into 0 to 100 equal portions, and wherein the equal portions quantity shared by setting value of backlight illumination is more, then corresponding backlight illumination is brighter, and equal portions quantity shared by the setting value of backlight illumination is about few, then corresponding backlight illumination is darker.For example, the setting value for backlight illumination is 100, then represent that setting value accounts for the backlight illumination of Touch Screen 110 100%, and namely the backlight illumination of Touch Screen 110 is the brightest.And be 80 for the setting value of backlight illumination, then represent that setting value accounts for the backlight illumination of Touch Screen 110 80%, now the backlight illumination of Touch Screen 110 then can than setting value be 100 backlight illumination darker.In the present embodiment, the first setting value of backlight illumination is such as between 80 to 100, but the present invention is not as limit.
Then, as shown in step S203, when touching sustainable existence and start mobile, velocity estimated unit 120 can obtain the translational speed of this touching.Then, as shown in step S205, velocity estimated unit 120 can judge whether the translational speed touched is greater than a speed threshold value.Generally speaking, speed threshold value is such as about user's speed (such as, after user starts Web-browser application, carrying out the average velocity of slide) corresponding when normal execution touching operation.Certainly, in the present embodiment, demand when speed threshold value can operate according to user sets.
In step S205, when velocity estimated unit 120 judges that the translational speed that this touches is less than or equal to speed threshold value, then as shown in step S207, backlight adjusting unit 130 can make backlight illumination maintain the first setting value.That is, when the translational speed of this touching is no more than speed threshold value, backlight adjusting unit 130 can not adjust the backlight illumination of Touch Screen 110.
On the other hand, when velocity estimated unit 120 judges that the translational speed that this touches is greater than speed threshold value, then as shown in step S209, backlight illumination can be downgraded the second setting value by backlight adjusting unit 130, and wherein the second setting value is less than the first setting value.For example, suppose that the first setting value of the backlight illumination of Touch Screen 110 is 80, and the second setting value is 60, then the setting value of backlight illumination can be downgraded 60 from 80 by backlight adjusting unit 130.That is, when the translational speed that user imposes on the touching of Touch Screen 110 is greater than speed threshold value, the backlight illumination of Touch Screen 110 can be dimmed, and thus, electronic installation 100 can save the power supply needed for backlight illumination.
For example, Fig. 3 A and Fig. 3 B is the schematic diagram of the adjustment backlight illumination shown by first embodiment of the invention.Specifically, utilize a finger on Touch Screen, apply a touching for user in figure 3 a, and suppose that the application program that electronic installation 100 performs at present is that a web browser is described.
Please refer to Fig. 3 A, user applies a touching 300 with finger on Touch Screen 110.At this, the setting value (that is, the first setting value) of the backlight illumination of Touch Screen 110 is such as 80, and namely the backlight illumination of Touch Screen 110 is brighter.When touching 300 sustainable existence Touch Screen 110 and when starting mobile, velocity estimated unit 120 can obtain the translational speed of this touching 300.And, when touching 300 continues to impose on Touch Screen 110, user starts to perform a slide to control the other guide that web browser presents webpage, wherein point in the process performing slide, successively contact at the contact area 31 of Touch Screen 110 and contact area 33 (direction as arrow movement).At this, velocity estimated unit 120 can obtain the translational speed that touching 300 starts to move to from contact area 31 contact area 33.In addition, velocity estimated unit 120 can judge whether the translational speed that touching 300 moves to contact area 33 from contact area 31 is greater than speed threshold value further.
At this, when supposing that touching 300 slowly moves to contact area 33 from contact area 31 and makes the translational speed of touching 300 be no more than speed threshold value, represent user be do on Touch Screen 110 one slowly slide to move webpage, with adjustment can the web page contents that presents by web browser, whole webpage can be watched in detail thus, and (namely backlight adjusting unit 130 now can maintain the setting value of the backlight illumination of Touch Screen 110, maintain the first setting value), allow user in the process browsed in detail, the content of the clear identification webpage of energy.
But, the translational speed supposing when touching 300 moves to contact area 33 from contact area 31 outpaces threshold value, represent that user does a slide fast on Touch Screen 110, this kind of situation normally occurs in user for going to other parts of webpage fast (such as, skip to webpage end or get back to the top etc. of webpage), because now user does not need the content of watching webpage in detail, as long as can state that roughly identification webpage is moved just can operate smoothly, therefore Touch Screen 110 can not need to maintain the higher backlight illumination of original brightness (namely, first setting value).That is, during user does not need detailed browsed web content, Touch Screen 110 can provide darker backlight illumination.Therefore, as shown in Figure 3 B, backlight adjusting unit 130 will downgrade the setting value (that is, downgrading the second setting value) of the backlight illumination of Touch Screen 110, and now the backlight illumination of Touch Screen 110 is darker.
Based on above-mentioned, when the translational speed that velocity estimated unit judges imposes on the touching of Touch Screen is less than or equal to speed threshold value, backlight adjusting unit can maintain the backlight illumination of Touch Screen.But when the translational speed that velocity estimated unit judges is greater than speed threshold value, backlight adjusting unit can downgrade backlight illumination.In other words, by judging that the translational speed imposing on the touching of Touch Screen 110 carrys out corresponding adjustment backlight illumination, the object of the power consumption of saving electronic installation 100 can so be reached.
Second embodiment:
Fig. 4 is the flow chart shown by second embodiment of the invention.The present embodiment is that the first embodiment is further applied, and still coordinates the electronic installation 100 of Fig. 1 to be described at this.
Please refer to Fig. 1 and Fig. 4, as shown in step S401, when electronic installation 100 is not in non-operating state, Touch Screen 110 detects the touching imposing on Touch Screen 110, and wherein Touch Screen 110 backlight illumination is now the first setting value.As shown in step S403, when touching sustainable existence and start mobile, velocity estimated unit 120 obtains the translational speed of touching.Then, as shown in step S405, velocity estimated unit 120 judges whether translational speed is greater than speed threshold value.When velocity estimated unit 120 judges that translational speed is less than or equal to speed threshold value, then as shown in step S407, backlight adjusting unit 130 makes backlight illumination maintain the first setting value.But when velocity estimated unit 120 judges that translational speed is greater than speed threshold value, then as shown in step S409, backlight illumination is downgraded the second setting value by backlight adjusting unit 130.At this, step S201, step S203, step S205, the step S207 of step S401, the step S403 of the present embodiment, step S405, step S407 and step S409 and the first embodiment are identical with step S209, therefore repeat no more in this.
In the present embodiment, after backlight illumination downgrades the second setting value, then as shown in step S411, velocity estimated unit 120 can judge whether this translational speed touched drops to and be less than or equal to speed threshold value.If so, then as shown in step S413, backlight illumination is increased back the 3rd setting value by backlight adjusting unit 130, and wherein the 3rd setting value is less than or equal to the first setting value, and is no more than a preset range with the difference of the first setting value.For example, suppose that the first setting value of backlight illumination is 80, and above-mentioned preset range is 5, then the 3rd setting value of backlight illumination can be such as 75 or 80.That is, the backlight illumination of the 3rd setting value is close but is less than the backlight illumination of the first setting value.
In other words, when user changes into lower translational speed in the touching that Touch Screen 110 does from higher translational speed (such as fast sliding touch screen 110) time (such as lentamente level and smooth mobile Touch Screen 110), represent that user is being quick sliding behaviour to switch in the process of the webpage that browser presents, in webpage, searched the content for viewing, and slow down the speed of done slide gradually, prepare to start to browse searched information in detail.At this, due to user be about to viewing webpage in content, therefore Touch Screen 110 need brighter backlight illumination is provided, with allow user can be distinct institute wish watch information.Therefore, the setting value of the backlight illumination of Touch Screen 110 first can be reduced to the second setting value to save power consumption from the first setting value, then increases to the 3rd setting value again and can know the content of watching on Touch Screen 110 to allow user.Thus, user is when operating Touch Screen 110, and electronic installation 100 can adjust the backlight illumination of Touch Screen 110, and then makes electronic installation 100 have higher power saving efficiency.
In addition, return step S411, if after backlight illumination downgrades the second setting value, velocity estimated unit 120 judges that translational speed that this touches is still when being greater than speed threshold value, then as shown in step S415, backlight adjusting unit 130 by backlight illumination by downgrade Touch Screen 110 a lowest visible brightness value before progressively downgrade backlight illumination.Say further, when the translational speed touched rises gradually, backlight adjusting unit 130 can accelerate backlight illumination to downgrade lowest visible brightness value.On the other hand, when the translational speed touched declines gradually, backlight adjusting unit 130 can slow down backlight illumination is downgraded lowest visible brightness value.
Specifically, suppose that backlight adjusting unit 130 is such as 0 to 100 equal portions distinguished according to backlight illumination, and the ratio downgrading backlight illumination is 10 at every turn, and hypothesis backlight adjusting unit 130 in step S409, backlight illumination to be downgraded the second setting value be 60, and lowest visible brightness value is 30, in the case, when the translational speed touched still is greater than speed threshold value, backlight adjusting unit 130 will downgrade the ratio of the setting value of backlight illumination gradually.Say further, backlight adjusting unit 130 can make the setting value of backlight illumination come down to 50,40 gradually from 60 (i.e. the second setting values), until the setting value of backlight illumination reaches 30 (i.e. lowest visible brightness values), then backlight adjusting unit 130 will no longer downgrade the setting value of backlight illumination.In addition, when the translational speed touched is larger, backlight adjusting unit 130 can accelerate backlight illumination from setting value be 60 downgrade 30 time speed.On the other hand, when touching translational speed more hour, backlight adjusting unit 130 can reduce backlight illumination from setting value be 60 downgrade 30 time speed.
Described herein, the lowest visible brightness value of the present embodiment is such as that user can know the minimum brightness corresponding to content identified in Touch Screen 110.For example, if when the setting value of backlight illumination is more than 30, user could know the content identified in Touch Screen 110, then the lowest visible brightness value of Touch Screen 110 is decided to be 30.Certainly, lowest visible brightness value can also the at present performed application program of corresponding electronic installation 100, or the pattern that electronic installation 100 is residing at present, or ambient brightness at that time and have different setting values.For example, generally speaking to perform the lowest visible brightness value corresponding to application program of web browser higher for electronic installation 100, and the lowest visible brightness value that electronic installation 100 is in corresponding to battery saving mode is lower.In addition, user also can set lowest visible brightness value according to actual product demand origin.
In the embodiment shown in fig. 4, after backlight illumination is downgraded the second setting value, backlight adjusting unit 130 by detecting the translational speed of touching, increase or downgrading backlight illumination, and can control the speed downgrading backlight illumination further.Thus, electronic installation 100 can have preferably effective utilization and reach the object of power saving.
In sum, the method for adjustment of backlight illumination of the present invention and electronic installation are when electronic installation is in mode of operation, detect the translational speed imposing on the touching of Touch Screen.When the translational speed touched is less than or equal to speed threshold value, backlight adjusting unit can maintain the backlight illumination of Touch Screen in the first setting value.But when the translational speed touched is greater than speed threshold value, backlight adjusting unit can downgrade backlight illumination to the second setting value.Thus, in due course between put by downgrading backlight illumination to reach the object of power consumption of saving electronic installation.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
