Fig. 1 is a synoptic diagram of the present invention;
Fig. 2 is the enlarged drawing at A place among Fig. 1.
Embodiment
Below in conjunction with description of drawings and embodiment the present invention is further described:
A kind of parallax thin barrier film shown in Fig. 1 to 2, itself and display panel combination are used, and comprise film 1, paint equipment by light and draw the parallax figure 2 that the image that can make in the display panel produces 3D effect on described film 1.
Parallax figure 2 described in the present invention comprises light occlusion part 21 and the light transmission department 22 that is disposed on the film 1.
The width of the width of described smooth occlusion part 21 and light transmission department 22 equates.
The width of described smooth occlusion part 21 is a 0.8-1.2 pixel wide, and the width of described light transmission department 22 is a 0.8-1.2 pixel wide.
Prepare the method for parallax thin barrier film of the present invention, may further comprise the steps:
A, making image document
Adjust the width of light occlusion part 21 and light transmission department 22 according to the pixel of display panel and make the parallax figure;
B, image document output
Adopting suitable optical plotter and pixel that the parallax figure in the steps A is outputed to light paints on the film;
C, profile moulding

Embodiment 1 makes the disparity barrier film that is used for mobile phone apple iphone 4
Known apple iphone 4 screen pixels: 326ppi, the 78um of official, actual 77.9um, the barrier film directly is layered on the screen top, and near because of the distance screen, printing opacity only needs little adjustment, through repeatedly trial and error test, last parallax film design is the live width line gap of 77.7um～79.0um.
What described apple iphone 4 adopted is capacitive screens; Consider that the blocked up sense of touch of film is insensitive, film is thin excessively to be easy to generate folding line and to scratch; So comparatively high-quality Kodak APR-7 light was painted the carrier of film as the parallax thin barrier film during selection PCB produced: this film thickness is that 7mil has stronger anti-scratch function, also can satisfy the conduction requirement simultaneously.
Select suitable optical plotter and pixel that image is outputed on the film membrane, the industrial optical plotter of PCB and LCD can reach 10,000dpi resolution (2.54um), Orbotech ' s LP
TM-9 even reach 50,800dpi resolution (0.5um) can satisfy the precision pixels requirement of present nearly all display screen.The design load that is used for the disparity barrier of apple iphone 4 is 77.7um～79.0um, and it is accurate more that light is painted the high more good more image lines of resolution; Paint by present design deviation area requirement light that resolution is minimum will to reach 10,000dpi is that spot definition is 2.54um.So select optical plotter Orbotech ' s LP
TM-9, resolution is high more, and corresponding energy consumption and time are just many more, and cost is high more.Adopt optical plotter Orbotech ' s LP
TM-9 paint at KodakAPR-7 light and to draw corresponding parallax figure on the film.
Adopt cut or punch die moulding, accuracy requirement cuts into suitable dimensions according to outward appearance.
Known apple ipad screen pixels: 132ppi (192um), barrier film directly are layered on the screen top, and near because of the distance screen, printing opacity only needs little adjustment, say repeatedly the trial and error test, and last parallax film design is the live width line gap of 190～194um.
What described apple ipad adopted is capacitive screens; Consider that the blocked up sense of touch of film is insensitive, film is thin excessively to be easy to generate folding line and to scratch; So comparatively high-quality Kodak APR-7 light was painted the carrier of film as the parallax thin barrier film during selection PCB produced: this film thickness is that 7mil has stronger anti-scratch function, also can satisfy the conduction requirement simultaneously.
Select suitable optical plotter and pixel that image is outputed on the film membrane, the industrial optical plotter of PCB and LCD can reach 10,000dpi resolution (2.54um), Orbotech ' s LP
TM-9 even reach 50,800dpi resolution (0.5um) can satisfy the precision pixels requirement of present nearly all display screen.
The design load that is used for the disparity barrier of apple ipad is 190～194um, and it is accurate more that light is painted the high more good more image lines of resolution; Paint by present design deviation area requirement light that resolution is minimum will to reach 8,000dpi is that spot definition is 3um.So select optical plotter Orbotech ' sLP
TM-9, resolution is high more, and corresponding energy consumption and time are just many more, and cost is high more.Adopt optical plotter Orbotech ' s LP
TM-9 paint at Kodak APR-7 light and to draw corresponding parallax figure on the film.
Adopt cut or punch die moulding, accuracy requirement cuts into suitable dimensions according to outward appearance.
Adopt said structure, pass the right eye of light transmission department transmission, and on the direction of user's left eye, blocked by the light occlusion part to the user from the eye image light beam of right eye sub-pixel.
Left-eye image light beam from the left eye sub-pixel passes the left eye of light transmission department transmission to the user, and is blocked by the light occlusion part on the direction of user's right eye.
Thereby left and right image arrives a left side and right eye respectively, makes the user can see the 3-D view of hope.
