Detailed Description
The invention will be explained in more detail by the following examples in connection with the accompanying drawings.
As shown in fig. 1, 2, 3 and 5, the transparent container 37, the semi-transparent reflecting plate 3, the orientation shade 6 and the liquid crystal display panel 1 are disposed inside the bracket 9; the imaging source is the lcd 1, the transflector 3 is a semi-transparent coated glass, the transparent container 37 (the transparent container is a square transparent glass container with an opening at the upper part and 4 sides being plane, the transparent container 37 is filled with water, the transflector 3 is put into water, the transflector 3 forms an angle alpha with the directional shade 6, alpha=50°, the directional shade 6, the first refractive surface 50 and the lcd 1 are parallel to each other, the directional shade 6 is attached to the lcd 1 (the directional shade 6 can be placed in a container and soaked together) as shown in fig. 4, the directional shade 6 adopts a conventional peep-proof film (or peep-proof sheet), the visual angle of the peep-proof film is beta-angle, beta=50 °, the side of the visual angle forms an angle 25 ° with the normal, and the light can normally pass through the directional shade 6, 18 within the range of beta-angle with the normal line as the center line, and the viewer can normally see the object behind the directional shade 6.
The peep-proof film (or peep-proof sheet) is a film manufactured by adopting an ultra-fine shutter optical technology (prior art), the film comprises a shading substance with an ultra-fine shutter structure, the shading substance is used for blocking light rays emitted from the imaging source to a specific direction, so that the light intensity of the light rays passing through the shading substance is reduced, the light intensity of the light rays emitted to a specific corresponding position can be obviously reduced, namely, a person at the corresponding position cannot see the imaging source or can only see the imaging source with very low brightness. The ultra-fine shutter optical technology comprises a transverse structure and a longitudinal structure, and can form left-right and/or up-down peep-proof effects.
As shown in fig. 3, the first virtual image 39 is a corresponding virtual image of the liquid crystal display 1 through the transflector 3; the third virtual image 61 is a corresponding virtual image of the fourth virtual image 60 through the transflector 3; the third virtual image 61 is a corresponding virtual image of the fourth virtual image 60 through the transflector 3; the fifth virtual image 67 is a corresponding virtual image formed by the directional light-shielding body 6 through the semi-reflection body 3; the sixth virtual image 68 is a corresponding virtual image of the eighth virtual image 70 through the transflector 3.
Since the corresponding light rays are totally reflected by the first refraction surface 50 and the second refraction surface 51, the second virtual image 36 is a corresponding virtual image formed by the first virtual image 39 passing through the first refraction surface 50, and the fourth virtual image 60 is a corresponding virtual image formed by the liquid crystal display screen 1 passing through the second refraction surface 51; the seventh virtual image 69 is a corresponding virtual image of the fifth virtual image 67 through the first refractive surface 50; the eighth virtual image 70 is a corresponding virtual image of the directional light blocking body 6 passing through the second refractive surface 51.
When the orientation blocking body 6 is not provided on the liquid crystal display panel 1, the third virtual image 61 and the second virtual image 36 are images (i.e., interference images) that can be seen by the viewer 18.
As shown in fig. 3, when the directional light shielding body 6 is disposed on the lcd 1, the first view line 64 and the fifth view line 66 of the viewer 18 form an angle of 5 ° and an angle of 24 ° with respect to the normal line of the fifth virtual image 67 of the directional light shielding body 6, respectively, and these angles are also smaller than β/2, that is, smaller than 25 °, and the viewer 18 can see the first virtual image 39 (transparent image, that is, the non-interference image to be seen by the viewer 18) according to the characteristics of the privacy film; the first line of sight 62 and the second line of sight 63 of the viewer 18 form an angle of 43 ° and an angle of 26 ° with respect to the normal line of the sixth virtual image 68 of the directional shade 6, respectively, which are both larger than β/2, i.e. larger than 25 °, and the viewer 18 cannot see the third virtual image 61 (interference image) according to the characteristics of the privacy film; the third line of sight 64 and the fourth line of sight 65 of the viewer 18 form angles of 26 ° and 45 ° respectively with the normal of the seventh virtual image 69 of the directional shade 6, which angles are likewise greater than β/2, i.e. greater than 25 °, and the viewer 18 cannot see the second virtual image 36 (interference image) depending on the characteristics of the privacy film. The same analysis, according to the different shielding structure designs of the support 9 (or the different viewing angles of the directional shielding body 6), includes the following first and/or second cases when the viewer 18 views at a position in front of the second refraction surface 51 (e.g. right in fig. 3): first, viewer 18 does not see the third virtual image 61 and the second virtual image 36 at all; second, only a small portion of the images of the third virtual image 61 and the second virtual image 36 (i.e., the images from which the majority of the interference has been removed and the brightness of these interfering images may be very low) are viewable by the viewer 18, so that complete or minimal removal of the interfering images is ultimately achieved by the apparatus.
The foregoing is only a preferred embodiment of the invention, and it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
