Applying mode, the present invention is described in further detail.
With reference to figure 1, Fig. 1 is a kind of structural schematic diagram of the display device of projection-type provided in an embodiment of the present invention, described
Display device includes：Film layer 11 to be projected and multiple display screens 12.
Wherein, the film layer to be projected 11 is used to be attached to the base material for needing to project；12 surface of the display screen is provided with
Prism film layer 13, the prism film layer 13 described wait throwing for making the light that the display screen 12 is sent out be emitted to according to preset direction
It penetrates in film layer 11.
The polarization direction for the light that the display screen 12 is sent out is vertical with the polarization direction of film layer 11 to be projected.
The display device is by the way that film layer to be projected to be attached on the base material for needing to project, in conjunction with display screen, you can realize and throw
The formula of penetrating is shown, and can improve projection scope by the use of multiple display screens, and the content of each display screen projection also may be used
With different, applicability is extensive, and simple in structure, and display effect is preferable.
Further, the film layer to be projected 11 is reflecting polarized wafer film layer.
Optionally, the film layer to be projected 11 is APF (Advance Polarizer Film) film layer, which is
Pass through PEN (Polyethylene Naphthalate, poly- naphthalenedicarboxylic acid butanediol fat) and CoPEN (70-naphthalate/
30-terephalate copolyester, 70/30 copolyesters) two kinds of organic materials stack made of film layer, the thickness of film layer
Degree is chosen as 26um, but has 800 multilayer organic matter stack layers based on the thickness, is the mutual friendship of high low-refraction between film layer
Folded, thickness can realize higher reflectivity by squeezing out and drawing process accurately controls, and by the stretching of film layer,
The performance of polaroid is realized, so that only direction and the identical light of film layer draw direction could pass through.
Further, as shown in Fig. 2, the prism film layer 13 includes：Basement membrane layer 21 and setting are in the basement membrane layer
UV adhesive films 22 on 21；
Wherein, the UV adhesive films 22 are the film layer of multiple prism structures formation of array arrangement.
Optionally, the material of the basement membrane layer 21 is COP (Cyclo Olefin Polymer) cyclic olefin polymer material
Material or TAC (Tri-Acetyl Cellulose) triacetate fiber cellulosic materials or PEN (Polyethylene Naphthalate)
Poly- naphthalenedicarboxylic acid butanediol fat material etc. is the membrane material of non-delay amount, that is to say, that the phase that light passes through the basement membrane layer
Position will not change, it should be noted that its material and be not construed as limiting in embodiments of the present invention.
Optionally, the UV adhesive films 22, which are the preparation method of the film layer of multiple prism structures formation of array arrangement, is
It is put in order according to certain by being made by roll-in UV adhesive films, to form the film layer of prism microstructure, wherein described
Ranging from 0 ° -180 ° of the corner angle of prism structures does not include endpoint value, and the apex angle seamed edge of prism structures is biased to should
Display screen presets light direction, as shown in Figure 3 and Figure 4, presets light direction in embodiments of the present invention and is not construed as limiting, can
Depending on as the case may be, the apex angle seamed edge of the prism structures on each display screen is biased to can be different.
Optionally, the altitude range of the prism structures in a first direction is 0.1um-50um, including endpoint value,
In, the first direction perpendicular to the basement membrane layer, such as the height of the prism structures in a first direction be 5um or
10um or 22um or 35um etc..
By the way that the prism film layer for presetting light direction is attached on display screen (emergent light has the display screen of polarization)
Face, to increase the amount of light of some angle, to change the visual angle of display screen.
Since the light being emitted from display screen 12 is polarised light, the polarised light is after prism film layer 13, due to prism film layer
13 be the film layer of not retardation, therefore after prism film layer 13, which does not change.Setting will
The polarization direction of its polarised light and the polarization direction of APF film layers to be projected are vertical, make to project the polarization in APF film layers to be projected
Light is reflected by APF film layers to be projected, into the eyes of access customer, it will be seen that the content opposite with above display screen, in turn
Content on display screen can be carried out to 180 ° of reversions, such user will see normal display in APF film layers to be projected
Content, as shown in letter A in Fig. 1 and letter C.
Further, the angular range between the film layer to be projected 11 and display screen 12 is 0 ° -180 °, does not include endpoint
Value, such as the angle between film layer 11 to be projected and display screen 12 is 50 ° or 90 ° or 130 ° etc., and each display screen
Angle between film layer to be projected can be different.
It should be noted that angle between the film layer to be projected 11 and display screen 12 is in embodiments of the present invention not
It is construed as limiting, it can be according to the light extraction of the distance and preset prism film layer on 12 bottom edge of display screen and the film layer bottom edges to be projected APF
Direction is adjusted.
Also, the central shaft of APF film layers to be projected and the central shaft of display screen can not wait projecting in same plane, APF
Film layer and the relative position of display screen can be according to the distances and preset rib on display screen bottom edge and the film layer bottom edges to be projected APF
The light direction of mirror coating is adjusted.
By foregoing description it is found that APF film layers to be projected need to be only attached to above the base material for needing to project by the display device,
Screen as projection can be realized projection-type and show, such as apply in vehicle-mounted new line display screen HUD (Head Up
Display on), it should be noted that the base material that APF film layers to be projected attach can be curling.
It follows that a kind of display device of projection-type provided by the invention needs to project by the way that film layer to be projected to be attached to
Base material on, in conjunction with display screen, you can realize that projection-type is shown, and can improve projection model by the use of multiple display screens
It encloses, and the content of each display screen projection can not also be the same, applicability is extensive, and simple in structure, and display effect is preferable.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
