Embodiment
Be illustrated in figure 9 the structural representation of one embodiment of the invention.This 3D image display 40, Yian dress succession, formed primarily of indicator screen element 50, parallax grating element 60 and a Lenticular element 70.
Wherein, this indicator screen element 50 can be made up of existing indicator screens such as liquid crystal display, plasma scope, Organic Light Emitting Diode (OLED) display, light emitting diode (LED) displays, and this screen there is color sub picture element arrangement can be arranged by known vertical stripe, mosaic, triangular shape and Pentile etc. and formed, in order to show the resultant image of what comes into a driver's more than (non-icon).
This parallax grating element 60 is made up of transparent base 61, parallax grating structure 62 and a transparent protective film 63.Wherein, this transparent base 61 is made up of the clear glass of a plate-like structure or acryl (PMMA), and this plate-like structure then has the surface evenness of height.
This parallax grating structure 62 is installed in the one side of this transparent base 61, is made up of multiple shading element 62a and multiple translucent element 62b.As shown in Fig. 1 ~ 2, those shading elements 62a and those translucent elements 62b can have vertical stripe or inclination strip architectural feature, and its horizontal width is respectively
and there is cellular construction width PB, should
between relation such as formula shown in (1) ~ (2); In addition, before this parallax grating structure 62 is installed on this this indicator screen element 50 with a mounting distance LB, for carrying out what comes into a driver's separation to this many what comes into a driver's resultant image, to show 3D image.
In addition, for the making of this parallax grating structure 62 by accurate processing procedures such as photoetch, relief printing plate transfer printing, intaglio plate transfer printings, those shading elements 62a and those translucent elements 62b can be replicated in the one side of this transparent base 61.In addition, also can in the one side of this transparent base 61, first be coated with the film (not shown) of one deck alternatively non-transparent, the laser engraving machine (not shown) of recycling technique of counterpoint and a tool precision positioning, for this alternatively non-transparent film, and correspond to the existing place of the plurality of translucent element 62b, hollow out this alternatively non-transparent film at this place, to complete the making of the plurality of translucent element 62b, the making of this parallax grating structure 62 can be completed.
Afterwards; again those shading elements 62a and those translucent elements 62b is covered to the diaphragm 63 of layer of transparent; as silicon dioxide (SiO2) film, to prevent the coming off and the impact of isolated environment, as humidity of those shading elements 62a and those translucent elements 62b.
This Lenticular element 70 is made up of multiple column shape lens 71, and wherein, single column shape lens 71 have vertical stripe or inclination strip architectural feature, and its focal length is f, and cellular construction width is PL.For this focal distance f and cellular construction width PL, it is made to have formula (3) ~ (4), to reach equivalent what comes into a driver's centrifugation.In fact, for the structure of element storehouse as shown in Figure 9, this Lenticular element 70 is because having a little thickness, and in the optical design of reality, the focal distance f of those column shape lens is slightly larger than the mounting distance LB of this parallax grating structure.
In addition, for the making of this Lenticular element 70, by volume to volume (Roll-to-Roll) roll printing processing procedure or hot padding processing procedure, to produce an independent element, then by contraposition laminating processing apparatus on this parallax grating element 60; Or by hot padding processing procedure, to be directly made on the transparent protective film 63 of this parallax grating element 60.
Be the structural representation of another embodiment of the present invention as shown in Figure 10.Substantially, this embodiment has the structure same with a upper embodiment, and only setting position is different.This 3D image display 40, Yian dress succession, formed primarily of indicator screen element 50, Lenticular element 70 and a parallax grating element 60.Wherein, this Lenticular element 70 is respectively an independent element with this parallax grating element 60, has the structure same with a upper embodiment and makes processing procedure, and having equivalent what comes into a driver's centrifugation between the two.Difference is that the transparent protective film 63 of circular surface 72 and this parallax grating element 60 of those column shape lens 71 is in the mode of closely pasting; by contraposition assembling and fixed mechanism (not shown), by integral with this parallax grating element 60 device for this Lenticular element 70.
In addition, as shown in figure 11, for this parallax grating element 60 device, by photoetch processing procedure, on the circular surface 72 of those column shape lens 71, first be coated with a black photoresistance film 64, light shield that recycling has this parallax grating structure 62 exposes this photoresistance 64, operation of developing, i.e. reproducible generation those shading elements 62a and those translucent elements 62b; Finally cover this transparent protective film 63 again, this parallax grating element 60 device can be completed.
In addition, also by the processing procedure of precise laser engraving, on the circular surface 72 of those column shape lens 71, first be coated with the film 64 of one deck alternatively non-transparent, the laser engraving machine (not shown) of recycling technique of counterpoint and a tool precision positioning, for this alternatively non-transparent film 64, and correspond to the existing place of the plurality of translucent element 62b, hollow out this alternatively non-transparent film 64 at this place, to complete the making of the plurality of translucent element 62b, the device of this parallax grating structure 62 can be completed.
In addition, it is made to have formula (3) ~ (4) for this focal distance f and cellular construction width PL, to reach equivalent what comes into a driver's centrifugation.In fact, for the structure of element storehouse as shown in Figure 10, the transparent protective film 63 in this parallax grating element 60, because having a little thickness, in the optical design of reality, the mounting distance LB of this parallax grating structure is slightly larger than focal distance f.
In addition, for those shading elements 62a described in above two embodiments and those translucent elements 62b, its effect, except being separated for equivalent what comes into a driver's, also has the effect of aperture.That is, keeping under the condition that this cellular construction width PB is constant, by changing the horizontal width of those shading elements 62a and those translucent elements 62b
such as:
And make
B'> B and
