In the specific implementation, owing to transparency carrier 200 is arranged on the display side of display floater 100, aobvious for not affecting as far as possible
Showing effect, should use high-resolution stipple pattern as far as possible, such as the size of site 202 is at the model of micron dimension to nanometer scale
In enclosing, such site 202 is nearly transparent to naked eyes in the dark state so that the light that display floater 100 sends is through transparency carrier
It is unaffected when 200.
In the specific implementation, site 202 can use the processes such as ink-jet, laser, etching or nanoimprint to obtain.Adopt
By different technique, the forming position of site 202 is different, for example with laser technology, site 202 can be made to be formed at transparent base
The inside of plate 200, and use etching technics that site 202 can be made to be formed at the transparency carrier 200 surface towards display floater 100
On.Suitable technique can be selected as required site 202 is made when reality is applied.
Will be understood that, although the site 202 shown in Fig. 1 and Fig. 5 is arranged on the inside of transparency carrier 200, but
Site 202 can also be arranged on the lower surface of transparency carrier 200, is i.e. arranged on the transparency carrier 200 table towards display floater 100
On face.With reference to Figure 10, each site 202 is arranged on lower surface, and the light that now the first light source 301 and 302 of dual-side sends is also
Scattering can occur in transparency carrier 200 and then in marginal portion or side outgoing.
As shown in figure 11, the intensity of the light of outgoing is not in the range of different angles for the first light source 301 or secondary light source 302
With.The experiment proved that, the marginal portion of transparency carrier intensity of the light of outgoing in the range of 60-80 ° is bigger, and side-looking
Person also typically goes to watch the content on display floater 100 in this angular range, therefore can play effective peep-proof effect.
Angle in Figure 11 is that to be perpendicular to the direction of transparency carrier be 0 °.
Second aspect, this utility model provides a kind of view angle switch method of any of the above-described display device, this display packing
Including:
Control the first light source 301 to open, to realize the first field-of-view mode；
Control the first light source 301 to close, to realize the second field-of-view mode；
Wherein, the visible angle scope of the first field-of-view mode is less than the visible angle scope of the second field-of-view mode.
It will be appreciated that when the visual angle of display device is the first visual angle, only emmetrope and the side of first side 201a
Depending on person it can be seen that show image, and the side-looking person being positioned at second side 201b can't see display image.And when display device
When visual angle is the second visual angle, the side-looking person of emmetrope, the side-looking person of first side 201a and second side 201b all it can be seen that
Display image, for the side-looking person hence for the second side, by being turned on and off the first light source 301, can make display device
Switch between peep-proof pattern and non-peep-proof pattern.
Certainly, if display device had both included the first light source 301, secondary light source 302, the then visual angle of display device are also included
Changing method includes:
Control described first light source and described secondary light source is opened, to realize the 3rd field-of-view mode；
Control described first light source and described secondary light source is closed, to realize the 4th field-of-view mode；
Wherein, the visible angle scope of described 3rd field-of-view mode is less than the visible angle model of described 4th field-of-view mode
Enclose.
It is understood that when the visual angle of display device is three visual angle, only emmetrope is it can be seen that show image,
And the side-looking person being positioned at first side 201a and second side 201b can't see display image.And when the visual angle of display device is the
During four visual angles, the side-looking person of emmetrope, the side-looking person of first side 201a and second side 201b is equal it can be seen that show image,
Visible the 4th visual angle here and above-mentioned second visual angle are identical.
It practice, the opening and closing of secondary light source 302 can also individually be controlled, so that the switching of visual angle size, also
That is, when secondary light source 302 is opened, it is positioned at the side-looking person of first side 201a and can't see display image, and secondary light source
During 302 closedown, it is positioned at the side-looking person of first side 201a it can be seen that show image, thus realizes the size switching at visual angle.
It should be noted that the positive visual angle in this utility model refers to that emmetrope watches the angle of panel, side-looking angle refers to
Side-looking person watches the angle of panel.
