It is clearer and more comprehensible, the followings are specific embodiments of the present invention.
Detailed description of the invention
In order to illustrate the embodiments of the present invention more clearly or it is existing in scheme, below will be in embodiment or existing description
Required attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only of the invention some
Embodiment without any creative labor, can also be according to these attached drawings for ordinary people in the field
Obtain other attached drawings.
Fig. 1 is the flow chart of mobile terminal display methods provided by the embodiment of the present invention；
Fig. 2 is the schematic illustration of mobile terminal display methods provided by the embodiment of the present invention；
Fig. 3 is that LED cooperates grating application example schematic diagram in the embodiment of the present invention；

Specific embodiment
Below in conjunction with attached drawing and embodiment, the present invention will be described in further detail.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, limit the present invention.
Embodiment of the method
As shown in Figure 1, mobile terminal display methods provided by the embodiment of the present invention, specifically includes as follows:
Step 101, the location information of user is detected；
In this step, mobile terminal can acquire the facial information of user by camera, according to facial information come
Determine the position of user.Optionally, dual camera is configured in mobile terminal, which can be fixedly installed on mobile whole
On the front panel at end, it can also be rotary pick-up head, can be adjusted two cameras to front panel by way of rotation
On.
When detecting the location information of user, the face-image of user is acquired by dual camera, is based on preset image
Recognizer identifies the position where eyes of user.The position of user is determined according to picture position where user's human eye.Specifically
Ground, when determining the location information of user based on position of human eye, the present invention is accomplished in that
Obtain the center where two positions；
The angle of straight line where straight line where determining center and each camera and dual camera, to be based on angle table
Show user position.
Here, in specific implementation, since dual camera can obtain two centers in each acquisition figure respectively
Position as in.The angle letter of above-mentioned straight line can be directly acquired according to parameters such as the focal lengths of the location information and dual camera
Breath.The angle information is angle information of the user relative to mobile terminal screen, according to the adjustable display of the angle information
Turned-on position in screen.
Further, it when having the human eye information of multiple people before dual camera detects mobile terminal, needs according to human eye position
Set the user of determining mobile terminal.Here, true according to the linear distance where everyone two centers to dual camera
Fixed user, it is preferred that choose this apart from shortest artificial user.The calculating of the distance, according to two centers every
Position in a acquisition image, the spacing between the focal length and dual camera of dual camera directly determine.For double camera shootings
The specific implementation of head ranging already belongs to technology well-known to those skilled in the art, for example, can refer to " dual camera ranging
OpenCV is realized " (http://blog.csdn.net/scyscyao/article/details/5562024), therefore here not
It is specifically described again.
Step 102, the turned-on position of LED array in display screen is adjusted, according to the location information of user to be based on lighting position
The LED array set will show that content passes through the position where being set to the optical grating projection to user of display screen surface.
In this step, mobile terminal configuration has LED array driving, LCD display and is set on LCD display
Grating Film.Wherein, LED array driving can drive the LED array of specified position to light；LCD display is then used to control
The particular content of display；Grating Film, which can control, to be lighted through LED array and the display content that projects is in specified area of space
In shown.
Here, the mapping table of preset position information and LED array turned-on position in the terminal, in the position according to user
In confidence breath adjustment display screen when the turned-on position of LED array, it can be directly acquired according to the mapping table and be believed with the position of user
The turned-on position of the corresponding LED array of manner of breathing.Here, user location and the LED quantity lighted and position number are one in the mapping table
One is corresponding.By pre-stored mode, it can be convenient and call at any time, shorten from dual camera catch position to driving LED's
Time improves processing speed to accomplish quick response.
As shown in Fig. 2, in figure 11 be dual camera, 12 be LED array, and 13 be grating, and 14 be LCD display.Here, false
If LED array is word order, and has 21 lamps, spacing 4mm, from right to left number 0-20 signal lamp.In horizontal extent,
User location can be uniquely determined by one group of angle coordinate (α, β).Wherein, α, β are respectively human eye center and the first camera shooting
The line of head, the angle with dual camera line.The angle information determines that the bright LED location of electricity (1 indicates to light, 0 indicates here
Extinguish), therefore corresponding table can have this information tentatively to provide, form is as shown in the table:
| Angle coordinate (α, β) | LED turned-on position (L1, L2 ... ... L20) |
| (0,0) | (0,0 ... ... 0) |
| (10,5) | (1,1,0,0 ... ... 0,0,1,1) |
| (20,10) | (1,0,1,0 ... ... 0,1,0,0) |
| …… | …… |
| (α1, β1) | (L1, L2 ... ... L20) |
| (α2, β2) | (L1 ', L2 ' ... ... L20 ') |
| (95,85) | (0,0 ... ... 1,1,1,1,0 ... ..., 0) |
Table 1
Above-mentioned mapping table only illustrates the mapping table within the scope of 0-90 °, due to the symmetry of mobile terminal, for
The mapping table of 90 ° of -180 ° of ranges and above-mentioned mapping table do symmetrical treatment, and it will not be described here.But it needs
Bright, above-mentioned mapping table only does explanation and illustration, is not used in limitation of the invention.In actual use, basis is needed
The service condition of user most adjusts turned-on position accordingly, accomplishes that brightness is properly uniform in entire moving process, can be completed
The adjustment of mapping table.
After determining the position that LED is lighted according to angle information, specified region is lighted by LED, then by grating to light
Do corresponding processing in road, it is ensured that the position where final ray cast to user, and other non-lit up positions due to
The effect of grating can not then see the content of display.Concrete principle is as follows:
Fig. 3 show LED cooperation grating application example schematic diagram.Optical path of the invention is much more complex relative to this diagram,
It briefly describes herein.Wherein, three, left side circle is LED, and the light of sending projects to right by grating lens, and will be right
Side is divided into many diamond-shaped areas, wherein the region of only mark square includes the light that all three LED light sources issue,
It can be identified by the human eye into clearly image, other regions do not include the light of all LED projections, therefore can not complete display screen
The content of curtain, therefore be fuzzy image seen in other parts.
Based on above-mentioned it is found that mobile terminal display methods provided by the embodiment of the present invention, by the position where user
It sets and is detected, after can determining that the LED array lighted, the LED array of only corresponding position are lighted according to the position of user
Through the processing of grating, it can be ensured that the position only where user can see the content of display.And when position occurs for user
When mobile, dual camera recapture customer position information, and when according to receiving new location information, it readjusts again a little
Bright corresponding LED array.Therefore, the present invention for user moved on a large scale in horizontal extent when, can tracking user position,
And according to the position of user dynamic adjustment display content in the display area in space, so that display content be avoided to be peeped by other users
The information security of user is effectively ensured in the situation of spy.
