For example, 103 and 104 may include:

After getting target angle angle value, electronic equipment can be according to the target angle angle value, from the electricity of display screen component Target electrochromic cells are determined in mutagens chromatograph, and target electrochromic cells is driven to change colour.When the electroluminescent change of target After color element discoloration, electrochromic layer can form several discoloration column and transparent column, and discoloration column and transparent column can the rows of interval Cloth can be spaced the transparent column of identical quantity between every two adjacent discoloration column, set electronics by electrochromic layer Standby display screen has visible angle corresponding with target angle angle value.

It should be noted that since electrochromic layer is covered on display screen, when target electrochromic cells into After row discoloration, electrochromic layer can form several discoloration column and transparent column (structure for forming shutter), so that display screen The some light of sending is blocked, so that display screen has certain visible angle.After the discoloration of target electrochromic cells Electrochromic layer and the schematic diagram of the section structure of display screen can be as shown in figure 8, electrochromic layer forms shutter at this time Structure.

It is understood that in the present embodiment, electronic equipment can use can independently change colour in electrochromic layer it is electroluminescent Color-changing unit is changed colour to control the visible angle of display screen, so that the visible angle to display screen is effectively controlled.

Referring to Fig. 9, Fig. 9 is another flow diagram of the control method of visible angle provided by the embodiments of the present application. The control method of the visible angle can be applied to electronic equipment, which includes display screen group provided in this embodiment Part, the display screen component may include display screen and electrochromic layer, which covers the display screen, the electrochromism Layer includes multiple electrochromic cells, and each electrochromic cells can independently change colour.

In one embodiment, the electrochromic cells in electrochromic layer can be made to the size of micron level, And it is realized using TFT (Thin Film Transistor, thin film transistor) array substrate technology to each electroluminescent The selectivity of color-changing unit controls, and is individually changed colour to control each electrochromic cells.That is, one end of TFT can be with One switch control line connection, one end control connection with a voltage, and one end is connect with electrochromic cells, such as Fig. 5 It is shown.

For example, as shown in figure 5, the electric signal controlled the electrochromic cells of the first row that electronic equipment receives For binary instruction 100.That is, electronic equipment needs that the first electrochromic cells 111 is driven to change colour, and the second electrochromism Unit 112 and third electrochromic cells 113 do not need then to change colour.So, electronic equipment can control route to first switch 211 send high level signal, to open the first switch 411 of the first row, second switch 412 and third switch 413.Later, It is (i.e. logical that electronic equipment can control first electrochromic cells 111 charging that route 311 is the first row by first voltage Electricity), so that the first electrochromic cells 111 be made to change colour.Later, electronic equipment can control route 211 to first switch and send Low level signal, to close the first switch 411 of the first row, second switch 412 and third switch 413.

For another example, the electric signal controlled the electrochromic cells of the second row that electronic equipment receives refers to for binary system Enable 010.That is, electronic equipment needs that the 5th electrochromic cells 115 is driven to change colour, and 114 He of the 4th electrochromic cells 6th electrochromic cells 116 do not need then to change colour.So, electronic equipment can control route 212 to second switch and send height Level signal, to open the 4th switch 414, the 5th switch 415 and the 6th switch 416 of the second row.Later, electronic equipment can It is charged with controlling second electrochromic cells 115 that route 312 is the second row by second voltage, to make the 5th electroluminescent change Color element 115 changes colour.Later, electronic equipment can give second switch control route 212 to send low level signal, to close the The 4th switch 414, the 5th switch 415 and the 6th switch 416 of two rows.

For another example, the next electric signal controlled the electrochromic cells of the first row that electronic equipment receives is two System instruction 000.That is, electronic equipment needs to cancel the discoloration of the first electrochromic cells 111.So, electronic equipment can be given First switch controls route 211 and sends high level signal, to open the first switch 411 of the first row, second switch 412 and the Three switches 413.Later, electronic equipment can control first electrochromism list that route 311 is the first row by first voltage Member 111 is discharged, so that the first electrochromic cells 111 be made to become transparent state again by coloured state.Later, electronic equipment can give first Switch control line 211 sends low level signal, opens to close the first switch 411 of the first row, second switch 412 and third Close 413.

It is understood that by the above-mentioned means, electronic equipment can control each electrochromism in electrochromic layer Unit is independent to carry out discoloration or non-discolouring.

In some embodiments, predetermined keyword can be the scene relating of the need for confidentiality such as some and payment, privacy Keyword, such as " input payment cipher ".

After getting the image of ambient enviroment, electronic equipment can detecte the people that whether there is pre-set user in the image The facial image of face image and non-pre-set user.In the present embodiment, pre-set user can be the owner of electronic equipment, rather than pre- If user can be other personnel except owner.

If detecting the facial image in the image of ambient enviroment there is only pre-set user, non-pre-set user may be not present Facial image controls then electronic equipment can execute other operations without the visible angle to display screen.

If detecting the face figure in the image of ambient enviroment there are the facial image of pre-set user and non-pre-set user Picture, then entering in 202.

In 202, if detecting the facial image in image there are the facial image of pre-set user and non-pre-set user, Electronic equipment determines the first spatial position and second space position, this first by structure light video camera head and image recognition technology Spatial position is the spatial position at the binocular center of the face of pre-set user, which is the face of non-pre-set user Binocular center spatial position.

For example, electronic equipment detects the people of the facial image for existing simultaneously owner in the image of ambient enviroment and non-owner Face image, then electronic equipment can determine the first spatial position and second by structure light video camera head and image recognition technology Spatial position.Wherein, which can be the spatial position where the binocular center of the face of owner, second sky Between position can for non-owner user face binocular center where spatial position.

It should be noted that the image in the available coverage of preposition structure light video camera head of electronic equipment.Work as inspection When measuring the facial image of the facial image for existing simultaneously owner in the image and non-owner, electronic equipment can be known by image Other technology identifies the binocular center of owner's face and the binocular center of non-owner's face.Due to structure light video camera head be one group by The system structure of projector and camera composition, after projector projects specific optical information to body surface and background, by taking the photograph As head acquisition, the information such as position and depth for calculating object according to the variation of optical signal caused by object, and then restore entire Three-dimensional space.Utilize the spatial position where every bit in the image of the available shooting of structure light video camera head.Therefore, knowing Object Chu not can be calculated using structure light video camera head behind the binocular center of owner's face and the binocular center of non-owner's face The characteristics of information such as position and depth, the first spatial position where the binocular center of the available owner's face of electronic equipment and Second space position where the binocular center of non-owner's face.

In 203, electronic equipment is using the spatial position where camera as space coordinate origin, according to space coordinate original Point, the first spatial position and second space position, determine the angle value of target angle, which is with space coordinate origin Vertex, and using straight line is one side of angle where the space coordinate origin and first spatial position, with the space coordinate origin It is the another side of angle with straight line where the second space position, which takes acute angle.

For example, in getting the first spatial position where the binocular center of owner's face and the binocular of non-owner's face Behind second space position where the heart, electronic equipment can be using the spatial position where structure light video camera head as space coordinate original Point, electronic equipment can determine target angle according to the space coordinate origin, the first spatial position and second space position later Angle value.Wherein, the target angle is using space coordinate origin as vertex, with the space coordinate origin and first spatial position Straight line where this two o'clock is one side of angle, is folder with straight line where the space coordinate origin and this two o'clock of second space position The another side at angle.Wherein, which takes acute angle.That is, electronic equipment can will be with the space at the binocular center of pre-set user The triangle that position, the spatial position at the binocular center of non-pre-set user, these three points of the spatial position of structure light video camera head are constituted It is determined as target angle angle value by the angle value at this angle on vertex of the spatial position of structure light video camera head in shape.

For example, referring to Fig. 10, where the binocular center of owner's face can be calculated using structure light video camera head Second space position B where the binocular center of one spatial position A and non-owner's face, with the sky where structure light video camera head Meta position is set to space coordinate origin O, then can form triangle AOB, then angle AOB is target angle.Utilize structure light video camera head Can calculate the first spatial position A space coordinate (x1, y1, z1) and second space position B space coordinate (x2, Y2, z2), then it can calculate the size of angle of departure AOB.

In 204, the angle value of target angle is determined as target angle angle value by electronic equipment.

For example, electronic equipment can be true by the angle value of the target angle after determining the angle value of target angle It is set to target angle angle value.

In 205, according to target angle angle value, electronic equipment determines that target is electroluminescent from the electrochromic layer of display screen component Color-changing unit.

In 206, electronic equipment driving target electrochromic cells change colour, when target electrochromic cells change colour Afterwards, electrochromic layer forms multiple discoloration column and transparent column, and discoloration column and transparent column are intervally arranged, every two adjacent discoloration column Between be spaced the transparent column of identical quantity so that display screen has visible angle corresponding with target angle angle value.

For example, 205 and 206 may include:

After getting target angle angle value, electronic equipment can be according to the target angle angle value, from the electricity of display screen component Target electrochromic cells are determined in mutagens chromatograph, and drive target electrochromic cells to change colour, such as become by transparent state Chromatic colorant state.After the discoloration of target electrochromic cells, electrochromic layer can form several discoloration column and transparent column, discoloration Column and transparent column can be intervally arranged, and the transparent column of identical quantity can be spaced between every two adjacent discoloration column, to pass through Electrochromic layer makes the display screen of electronic equipment have visible angle corresponding with target angle angle value.Wherein, in target angle Value be acute angle when, the visible angle of the display screen can be twice of size of target angle angle value.

It should be noted that since electrochromic layer is covered on display screen, when target electrochromic cells into After row discoloration, electrochromic layer can form several discoloration column and transparent column (structure for forming shutter), so that display screen The some light of sending is blocked, so that display screen has certain visible angle.

In one embodiment, the position of angle value Yu target electrochromic cells can be previously stored in electronic equipment The mapping table set.So, after getting target angle angle value, electronic equipment can be obtained according to the mapping table The position of target electrochromic cells corresponding with the target angle angle value.Behind the position for getting target electrochromic cells, Electronic equipment can drive target electrochromic cells to change colour.

For example, mapping table can be stored in advance in electronic equipment, the mapping table record all angles value and Its corresponding binary system control instruction, the binary system control instruction are used to control the electrochromic cells of every a line, i.e., every a line Electrochromic cells control instruction it is identical.For example, including 110 electrochromic cells, this 100 electricity with electrochromic layer Mutagens color element is distributed in 10 rows 11 column.For example, 40 degree of the corresponding binary system control instruction of angle value is 10101010101.The binary system control instruction 10101010101 indicates in the electrochromic cells of every a line from left to right 1,3,5,7,9,11 electrochromic cells need to change colour, and the 2nd, 4,6,8,10 electrochromic cells do not need to change colour.That is, with The corresponding target electrochromic cells of 40 degree of angle value are the 1st, 3,5,7,9,11 electrochromic cells of every a line.

For another example, for example, 80 degree of the corresponding binary system control instruction of angle value is 10010010011.Binary system control Instruction 10010010011 indicates in the electrochromic cells of every a line from a left side to there is the 1st, 4,7,10,11 electrochromic cells It needs to change colour, the 2nd, 3,5,6,8,9 electrochromic cells do not need to change colour.That is, target electricity corresponding with 60 degree of angle value Mutagens color element is the 1st, 4,7,10,11 electrochromic cells of every a line.

It is understood that being located at angle of visibility in the case where the display screen of electronic equipment has certain visible angle Non- owner user except degree will be unable to see the content of display screen display, and so as to play, to prevent non-owner from peeping aobvious Show the effect of content.

It in one embodiment, can be with after 206 electronic equipments driving target electrochromic cells are changed colour Include the following steps:

If detecting the face in the coverage of the camera of electronic equipment there is only pre-set user, electronic equipment It controls target electrochromic cells and cancels discoloration.

For example, detecting the face in the coverage of the camera of electronic equipment there is only owner, and no longer deposit In the face of non-owner, then it is considered that there is no can be carried out the personnel peeped in ambient enviroment.In this case, electric Sub- equipment can control target electrochromic cells and cancel discoloration.That is, all electrochromism of the electrochromic layer of electronic equipment The equal no power of unit, so that transparent state is presented in electrochromic layer on the whole.In this case, electronic equipment is no longer to display screen Carry out anti-peeping protection.Due to no longer needing to be powered to target electrochromic cells, electronic equipment can be reduced Power consumption.

In one embodiment, electronic equipment can also carry out this reality to the content that display screen is shown in following scene The anti-peeping protection of example offer is provided:

When detecting that ambient noise is more than preset threshold, electronic equipment obtains the history travel behaviour habit of pre-set user Data；

It is accustomed to data according to history travel behaviour, whether electronic equipment prediction pre-set user is located in public transport；

If predicting pre-set user to be located in public transport, electronic equipment obtains the image of ambient enviroment.

For example, when detecting that the decibels of noise of ambient enviroment are more than preset threshold, the available machine of electronic equipment Main history travel behaviour is accustomed to data, and is accustomed to whether data prediction owner is located at public transport according to the history travel behaviour In tool.

If predicting owner not to be located in public transport, electronic equipment can execute other operations.

If predicting owner to be located in public transport, it is considered that owner is located at crowded public transport work In tool, the content on display screen, which is easily stolen, is peeped, and electronic equipment obtains the image of ambient enviroment at this time, and is detecting the image It is middle there are in the case where the facial image of owner and the facial image of non-owner, obtain target angle angle value, and according to the target angle Angle value determines target electrochromic cells, to drive target electrochromic cells to change colour, when target electrochromic cells After discoloration, electrochromic layer forms multiple discoloration column and transparent column, and discoloration column and the transparent column are intervally arranged, and every two is adjacent Discoloration column between be spaced the transparent column of identical quantity so that display screen has visible angle corresponding with target angle angle value.

In one embodiment, electronic equipment can also receive preset gesture control instruction or voice from user Control instruction, and after receiving these preset gesture control instructions or phonetic control command, the image of ambient enviroment is obtained, And in the images comprising pre-set user facial image and non-pre-set user facial image in the case where, utilize electrochromism Layer controls the visible angle of display screen.
