The situation switched between visual angle and wide viewing angle.And if want to be switched to wide viewing angle, need peep-proof film to be moved from peep-proof display
Remove, using upper very inconvenient.Fig. 1 is illustrated that on basalis 52 and sets shutter microstructured layers 51, can block oblique visual angle
The structure of peep-proof film 50.
At present, in the market occurs in that one kind realizes that peep-proof film 60 is anti-with non-in peep-proof state using electrochomeric glass principle
The technology of switching at runtime between state, know-why are peeped as shown in Fig. 2 it is mainly the micro- knot of shutter set on basalis 63
Electrochromic layer 62 is set up in each both sides of transparent area 64 of structure layer 61.This electrochromic layer 62 can be realized transparent in the case of energization
Switching between state and shading state, so as to realize switching of the display between wide viewing angle and narrow viewing angle.But this way
The disadvantage is that, lateral transmitance during peep-proof state is poor, so as to cause peep-proof effect greatly to reduce, and this peep-proof film 60 making
Technique is excessively complicated, high cost, it is impossible to ensure the reliable realization of peep-proof effect.
In addition, in the market have also appeared uses PDLC (PDLC) or PNLC (polymer network liquid crystal) conduct
Light absorbing material, or realize that peep-proof changeable between peep-proof state and non-peep-proof state shows using structures such as single LCD
Device.But from actual implementation it can be seen that, this scheme the disadvantage is that, peep-proof state to there is lateral transmitance too high, very poor
Positive transmitance, the conversion between wide, narrow viewing angle is very slow, in continuous wide, narrow viewing angle switching the performance of display and
Stability is driven drastically to be deteriorated.
As can be seen here, a kind of technical scheme for solving above-mentioned traditional peep-proof display shortcoming is designed, is to be badly in need of at present
The problem of solution.
The content of the invention
It is an object of the invention to provide a kind of peep-proof display, it can prevent in the peep-proof state of narrow viewing angle and the non-of wide viewing angle
Peep between state and realize being switched fast, peep-proof effect is good.
To achieve these goals, present invention employs following technical scheme：
A kind of peep-proof display, it is characterised in that：It includes liquid crystal display panel, the back side of liquid crystal display panel be provided with by
The collimated light that most of light that backlight sends is adjusted to collimated light injection realizes module, liquid crystal display panel and collimated light reality
The peep-proof state that can switch to realize narrow viewing angle between all-transparent state and frosted state is provided between existing module non-anti- with wide viewing angle
Handoff functionality between state is peeped, and the strong and weak light modulation film of peep-proof effect is adjusted by the different translucent progressive states of gray scale.
The collimated light realizes that module includes peep-proof film, the reflection diaphragm group of setting stacked on top of one another, peep-proof film and the tune
Light film connects, wherein：Reflection diaphragm group includes the prism film of setting stacked on top of one another, lower diffusion barrier, light guide plate, reflectance coating successively,
Prism film connects with peep-proof film, and prism film is upper and lower prism film or composite prism film.
Or, the collimated light realizes that module includes reflection diaphragm group, and reflection diaphragm group includes setting stacked on top of one another successively
Reversed prism film, light guide plate, reflectance coating, reversed prism film connects with the light modulation film.
It is an advantage of the invention that：
The present invention can be realized being switched fast between the peep-proof state of narrow viewing angle and the non-peep-proof state of wide viewing angle, specifically,
When the present invention is in peep-proof state, the positive transmitance (up to more than 89%) high towards beholder, mist degree low (being less than 0.5%),
Nephelometric turbidity unit is low, and the image display effect of liquid crystal display panel is good, and lateral transmitance is low, and peep-proof effect is good, that is, realize effect
Splendid narrow viewing angle, and the present invention in non-peep-proof state when, towards positive transmitance (still having more than 78%) high, the mist of beholder
Degree high (up to more than 95%), nephelometric turbidity unit are high, can well on the basis of display image in liquid crystal display panel, and light is obtained very well
Diverging, such that it is able to obtain very wide visible angle, that is, realize the wide viewing angle of excellent.
The present invention need to only power when light modulation film switches to all-transparent state and frosted state, and the holding of both states
The switching time that need not be consumed between electric energy, and both states is very short, thus the present invention can realize peep-proof state with it is non-
Rapid switching between peep-proof state, while the continuous switching between peep-proof state and non-peep-proof state, will not be to display performance and driving
Stability is impacted, and very little is influenceed on battery durable.
Manufacture craft of the present invention is simple, and low cost is widely portable to the small-medium sizes such as mobile phone, flat board, notebook and shows
The secret protection of device.
