Description
Technical field
The present invention relates to stealthy display technology field, specifically a kind of stealthy display methods based on light field compensation.
Background technology
At present in stealthy display field, mainly using liquid crystal polarized principle, it is specifically：By controlling different pixels position
The electrode for the liquid crystal put, change the liquid crystals twist direction of location of pixels at this, so as to change the inclined of the linearly polarized photon of the liquid crystal
Shake direction, and regardless of the polarization light polarization direction, its brightness is certain, so seeing the general viewers of this light source, is seen
To image be a piece of uniform white image, so as to reach stealthy effect.By using polarizer as picture reproducer after,
Polarization direction is filtered with polarised light of the polarizer into 90 degree, and different brightness can be presented according to the difference of angle in other light
Image.
Due to being limited by displaying principle, using the stealthy display device of this method making, stealthy region is uncontrollable,
I.e. equipment is once produced, and stealthy region is to the eternal stealth of general viewers, it is impossible to shows any image information.In addition, should
Equipment uses liquid crystal apparatus so that application is restricted significantly.
The content of the invention
The present invention is directed to above-mentioned problem, there is provided a kind of stealthy display methods based on light field compensation, solves
The stealthy uncontrollable problem of effect, can realize stealthy and profiling switch mode.
The invention provides a kind of stealthy display methods based on light field compensation, comprise the following steps：
(1), image layered, the figure layer of Overlapping display, which includes, on screen is intended to hiding show layers and is compensated for stealth
Compensation figure layer, show layers and compensation figure layer be complementary relationship, both superpositions after in the single solid-color image of screen display；
(2), polarization manipulation, show layers and compensation figure layer are subjected to polarization manipulation, show layers is inclined with compensation figure layer
The direction that shakes is orthogonal；
(3), stealthy display, by compensating figure layer with show layers polarization direction identical polarizer filter, through display
Show layers.
Further, plain white image is shown after the show layers described in step (1) and compensation map overlay.
Further, the show layers described in step (1) and compensation figure layer can also show identical image information.
Further, the show layers described in step (2) is handled by longitudinal polarizer, and compensation figure layer passes through laterally inclined
The piece that shakes processing.
Stealthy display methods of the present invention based on light field compensation, the stealthy display of image is realized, improve stealthy imaging effect
Fruit, while stealthy and profiling switching can be realized.
Brief description of the drawings
Fig. 1 is the schematic diagram of stealthy display methods of the present invention based on light field compensation.
Embodiment
It is to be appreciated that in the case where not conflicting, the feature in the embodiment of the present application and embodiment can be combined with each other, and be
Facilitate understanding, the technical characteristic for not having to be described in detail in the present invention belongs to prior art.
The invention provides a kind of stealthy display methods based on light field compensation, comprise the following steps：
(1), image layered, the figure layer of Overlapping display, which includes, on screen 1 is intended to hiding show layers 2 and is mended for stealth
The compensation figure layer 4 repaid, show layers 2 and compensation figure layer 4 are complementary relationship, in the single pure color figure of screen display after both superpositions
Picture；
(2), polarization manipulation, show layers 2 and compensation figure layer 4 are subjected to polarization manipulation, show layers 2 and compensation figure layer 4
Polarization direction it is orthogonal；
(3), stealthy display, by filtering compensation figure layer 2 with the polarization direction identical polarizer 6 of show layers 2, through aobvious
Show show layers 4.
In a preferred embodiment, image figure layer 2 and compensate figure layer 4 as complementary relation, a variety of various combination colors can
Same color is formed with superposition, imaging figure layer and compensation figure layer are arranged to complementary relationship in this principle, each picture on screen
Same color can be all shown after the color combination superposition of two figure layers on vegetarian refreshments, white is could be arranged to, shows after map overlay
Show simple white, the information for imaging figure layer is hidden.Show layers is handled by longitudinal polarizer, compensation figure layer carries out horizontal
To polarizer handle, both be superimposed after, what domestic consumer 8 was seen is still single solid-color image, if user 7 by using with
Show layers polarization direction identical polarizer 6, can filter compensation figure layer, and display is intended to hiding show layers.
Similarly, image figure layer and compensation figure layer may also set up identical image information, folded in the polarised light of different angle
Under adding, although reducing printing opacity brightness, but still normal display pattern can be realized with display image information.
Stealthy display methods of the present invention based on light field compensation, can apply to projection or liquid crystal display, realizes image
Stealthy display, improve stealthy imaging results, while stealthy and profiling switching can be realized.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
All any modification, equivalent and improvement made within the spirit and principles of the invention etc., it should be included in the present invention's
Within protection domain.
