Figure, the method for the measurement angle can be used in above-mentioned terminal, and the method for the measurement angle can include following several realize and walk
Suddenly：
Step 201：Under angulation pattern, the angulation indication signal based on reception, deploy or fold the screen of the terminal, should
Angulation indication signal includes amount of expansion angle indicative signal and folds angulation indication signal.
In the embodiment of the present application, terminal is provided with angle measuring function, in fact, starting the angulation pattern that is, starting
The angle measuring function of the terminal.Afterwards, if terminal receives angulation indication signal, illustrate that user needs to survey using the terminal
Measuring angle.
As it was noted above, because the screen of the terminal can be folded towards outside, can also inwards be folded, therefore,
The angulation indication signal can include amount of expansion angle indicative signal and fold angulation indication signal, that is to say, can pass through expansion
The mode of the screen of terminal carrys out measurement angle, can also be by way of the screen for folding terminal come measurement angle.
Wherein, the angulation indication signal can be triggered by user, and the user can be triggered by assigned operation, and this specifies behaviour
Make that clicking operation, slide etc. can be included, the embodiment of the present application does not limit this.
For example, expansion angulation instruction option can be provided with the terminal and folds angulation instruction option, wherein, the expansion
Angulation indicates that option and folding angulation instruction option can be physics option, also can be virtual option.When user thinks
It can click on expansion angulation instruction option by way of deploying screen when measurement angle, be referred to triggering the expansion angulation
Show signal, when user wants the measurement angle by way of folding screen, folding angles instruction option can be clicked on, to touch
Send out the folding angulation indication signal.
It is noted that in the embodiment of the present application, you can the measurement angle in a manner of by deploying screen, can also
The measurement angle by way of folding screen, in this way, improving the flexibility of measurement angle.
Further, in practical implementations, the terminal can start the angulation after angulation pattern enabled instruction is received
Pattern.Wherein, the angulation pattern enabled instruction can be triggered by user, and the user can be triggered by above-mentioned assigned operation.
For example, can be provided with angulation pattern startupoptions in the terminal, the angulation pattern startupoptions can be physics
Option, or virtual option.When user wants to pass through terminal measurement angle, the angulation pattern can be clicked on and start choosing
, to trigger the angulation pattern enabled instruction.When terminal detects the angulation pattern enabled instruction, start the angulation pattern.
Further, in a kind of possible implementation, when receiving angulation pattern enabled instruction, and the screen is detected
When curtain is towards interior folding, start the angulation pattern.
As it was noted above, because the screen of terminal can be folded towards outside, can also inwards be folded, also,
In application scenes, it may be necessary to measure the angle of the more coarse object in some surfaces, for example, it is desired to measure certain surface compared with
For the angle of coarse woodwork.Now, in order to prevent scratching display screen when by terminal measurement angle, when terminal receives
During angulation pattern enabled instruction, it is towards interior folding or towards outer folding that can detect the screen.If the screen is towards interior folding,
It is the outside measurement angle using screen to illustrate subsequent terminal, outer due to screen at this point it is possible to think that display screen will not be damaged
Side can generally cover one layer of protective case, and therefore, terminal can start the angulation pattern, to utilize the outside measurement angle of the screen
Degree, its specific implementation are seen below., whereas if the screen is towards outer folding, illustrate subsequently to utilize display screen side to measure
Angle, now, display screen may be damaged to, in order to protect the display screen, the angulation pattern can not be started.
It is above-mentioned when receiving angulation pattern enabled instruction, detect whether the screen is towards interior folding, when detecting screen
When being towards interior folding, start the angulation pattern, in this way, can be played a protective role to screen.
Further, can be with voice when receiving angulation pattern enabled instruction, and detecting the screen towards outer folding
The mode of prompting sends alarm, with prompt user's current screen be towards outer folding, in order to user change folding mode, for example,
Screen is changed to towards interior folding etc..
It should be noted that it is above-mentioned when receiving angulation pattern enabled instruction, and detecting the screen towards interior folding, open
It is only a kind of optional implementation to move the angulation pattern, in practical implementations, as it was noted above, terminal can not also detect this
Screen is inwardly or towards outer folding, but when receiving angulation pattern enabled instruction, directly initiates angulation pattern.
Step 202：Judge whether two half screens of the screen are parallel with two side difference where angulation to be measured.
In order to realize the measurement for treating measurement angle, it is necessary to judge the two of the screen during screen deploys or folds
Whether individual half screen and two sides where angulation to be measured are parallel respectively.In the specific implementation, because terminal can be by deploying to shield
The mode measurement angle of curtain, can also by way of folding screen measurement angle, it is therefore, different according to occupation mode, it is above-mentioned
Judge two half screens of the screen it is whether parallel with two side difference where angulation to be measured can include it is following several possible
Situation：
The first situation：If the angulation indication signal is the amount of expansion angle indicative signal, when detecting the two of the screen
Individual half screen can not continue expansion and can not continuing deployment of duration when reaching the first preset duration, determine two of the screen
Half screen is parallel with two side difference where angulation to be measured.
Wherein, first preset duration can also can be write from memory by user's self-defined setting according to the actual requirements by the terminal
Recognize setting, the embodiment of the present application is not limited this.
If the angulation indication signal is amount of expansion angle indicative signal, illustrate terminal measurement angle by way of deploying screen
Degree.In that case, the screen of terminal can be folded up, afterwards, the terminal is put into the place for needing measurement angle,
Wherein, a face half screen of terminal is close to a line of angulation to be measured, and then, user can unclamp another face, and now, terminal is certainly
It is dynamic to be deployed.In the process, whether two half screens of terminal detection screen can continue to deploy, once detect the screen
Two half screens can not continue expansion and can not continuing deployment of duration reach certain time length, then illustrate the another side of terminal
Half screen may be lived by another side bumper of object, at this point it is possible to where determining two half screens and the angulation to be measured of the screen
Two side difference is parallel.
For example, user can fold up the screen of terminal 20, and by a face of terminal 20 close to object to be measured
21 a line 21a, as shown in Fig. 2 B (1), then, user can unclamp another face, and now, terminal 20 is opened up automatically
Open, as shown in Fig. 2 B (2).When another face of terminal 20 fits to the another a line 21b of object 21 to be measured, such as Fig. 2 B
(3) shown in, another face of terminal 20 can not continue to deploy, when can not continuing deployment of duration to reach above-mentioned first default
During duration, it may be determined that another face is parallel with the another a line 21b of object 21 to be measured, at this point it is possible to determine the screen
Two half screens of curtain are parallel with two side difference where angulation to be measured.
Second of situation：If the angulation indication signal is the folding angulation indication signal, when detecting the two of the screen
When the duration that individual half screen can not continue to fold and can not continue to fold reaches the second preset duration, two of the screen are determined
Half screen is parallel with two side difference where angulation to be measured.
Wherein, second preset duration can be defined setting according to the actual requirements by user, can also be given tacit consent to by the terminal
Set, the embodiment of the present application is not limited this.
If the angulation indication signal illustrates terminal measurement angle by way of folding screen to fold angulation indication signal
Degree.In that case, two half screens of screen can be expanded to horizontality, afterwards, the terminal, which is put into, to be needed to measure
The place of angle, wherein, a face half screen of terminal is close to a line of angulation to be measured, and then, user can unclamp another face,
Now, terminal is folded automatically.In the process, whether two half screens of terminal detection screen can continue to fold, once
The duration that detecting two half screens of the screen can not continue to fold and can not continue to fold reaches certain time length, then illustrates
The another side half screen of terminal may be lived by another side bumper of object, at this point it is possible to determine two half screens of the screen with treating
Two sides difference where measurement angle is parallel.
For example, the screen of terminal 20 can be expanded to horizontality by user, and by a face of terminal 20 close to be measured
The a line 22a of object 22 is measured, as shown in Fig. 2 C (1), then, user can unclamp another face, and now, terminal 20 is entered automatically
Row folds, as shown in Fig. 2 C (2).When another face of terminal 20 fits to the another a line 22b of object 22 to be measured, such as scheme
Shown in 2C (3), another face of terminal 20 can not continue to fold, and when the duration that can not continue to fold, to reach above-mentioned second pre-
If during duration, it may be determined that another face is parallel with the another a line 22b of object 22 to be measured, at this point it is possible to determine this
Two half screens of screen are parallel with two side difference where angulation to be measured.
Step 203：When two half screens for detecting the screen are parallel with two side difference where angulation to be measured, it is determined that
Folding angles after the screen currently expansion or folding, the folding angles refer to two viewing areas that the screen is formed after folding
Between angle.
In order to make it easy to understand, first combining Fig. 2 D here, the folding angles are explained.Above-mentioned two viewing area
Refer to two display surfaces that screen is formed after folding.For example, with reference to figure 2D, viewing area 1 can be formed after screen is folded
With viewing area 2, the folding angles of screen are the angle, θ between viewing area 1 and viewing area 2.Moreover, when screen is exhibition
During open state, θ=180 °；When screen is folded and is located at inner side, 0 °≤θ<180°；When screen is folded and is located at outside
When, 180 °<θ≤360°.For example, when screen is folded to greatest extent inwardly so that mutually paste two viewing areas of screen
During conjunction, θ=0 °；When screen is folded to greatest extent outwardly so that when terminal rear shell is bonded to each other, θ=360 °.
As shown in Fig. 2 B (3), it can be appreciated that when two half screens and two sides where angulation to be measured that detect the screen
When parallel respectively, the current folding angles of the screen are identical with the size of angulation to be measured or round angle each other, therefore, in order to determine to treat
The size of measurement angle, terminal determine the current folding angles of the screen.
It should be noted that when terminal is often in a kind of folded state, can determine to work as by angle measurement technique
Preceding folding angles.Wherein, terminal determines that the specific implementation of current folding angles may refer to phase by angle measurement technique
Pass technology, the embodiment of the present application are not limited this.
Step 204：The angle of the angulation to be measured, and angle determined by display on the screen are determined based on the folding angles
Degree.
In practical implementations, when terminal is inwardly or towards during outer folding progress angular surveying, being determined based on the folding angles should
The specific implementation of the angle of angulation to be measured is also different, next, by the terminal towards illustrating exemplified by interior folding measurement angle.
As it was noted above, when two half screens for detecting the screen are parallel with two side difference where angulation to be measured,
The current folding angles of the screen are identical with the size of angulation to be measured, and therefore, terminal can be directly by the current folding of the terminal
Angle-determining is the angle to be measured.
The size of angulation to be measured is known for the ease of user, terminal can show identified angle on the screen, with
It is easy to user to check.Further, terminal can angle determined by any half screen display in the screen, or, the end
Hold angle determined by can also being shown on two half screens of the screen.
Further, on the screen after angle determined by display, whether detection is currently in silent mode, if working as
Before be not at silent mode, then identified angle is played by way of voice message.
In a kind of possible implementation, after terminal shows identified angle on the screen, when user wants to look into
, it is necessary to deploy the screen of the terminal, in this way, taking the regular hour during angle determined by seeing.In order to cause user
Quickly know the angle of angulation to be measured, the terminal shown on screen determined by after angle, can also detect the terminal is
It is no to be in silent mode, if it is determined that be not presently within silent mode, then the terminal can also play identified angle automatically,
For example, the voice of terminal plays can be：" measurement angle is 90 degree ".So, it is ensured that user can quickly be known to be measured
The size of angulation, improves Consumer's Experience.
Certainly, can be without speech play, in this way, avoiding user from being in quiet if the terminal is currently at silent mode
Noise produced by sound field institute automatic speech plays.
It should also be noted that, above-mentioned illustrated so that terminal carrys out measurement angle towards interior folding as an example.In practical application
In scene, when terminal towards outer folding with measurement angle when, it is above-mentioned to determine that the angle of the angulation to be measured includes based on the folding angles：
