Description
Technical field
The utility model relates to integration imaging 3D displays, and more specifically, the utility model relates to the collection based on backlight
At imaging 3D display device.
Background technique
Integration imaging 3D display technology is a kind of without any true 3D display technology for helping view equipment.The technology has naked eye
The process of the characteristics of viewing, recording and displaying are relatively easy, and can show the stereo-picture of full parallax and authentic color, are mesh
One of the hot spot technology of preceding 3D display.But crosstalk be still limitation the widely applied principal element of integration imaging 3D display it
One.
Summary of the invention
The utility model proposes the integration imaging 3D display devices based on backlight, as shown in figure 1 and 2, feature
It is, including backlight, pinhole array and display screen；Pinhole array is between backlight and display screen, backlight, pin hole battle array
Column and display screen are placed in parallel, and corresponding alignment；The spacing of backlight and pinhole array is no more than pinhole array and display screen
Spacing；
The thickness of pinhole arraytAre as follows:
(1)
Wherein,pIt is the pitch of pin hole and image primitive,wIt is the aperture of pin hole,gIt is between pinhole array and display screen
Away from；The hole wall of pin hole is light-absorption layer in pinhole array；Display screen is for showing image primitive；Each image primitive is all passed through correspondence
The light of pin hole illuminates, and only illuminates corresponding image primitive by the light of each pin hole, to eliminate crosstalk；
The horizontal viewing visual angle of integration imaging 3D display device based on backlightθ 1With vertical viewing visual angleθ 2It is respectively as follows:
(2)
(3)
Wherein,mFor the number of pin hole in horizontal direction in pinhole array,nFor pin hole in vertical direction in pinhole array
Number,lFor viewing distance.
Preferably, pinhole array is reflective layer close to the face of backlight.
Compared with prior art, the utility model has the following beneficial effects: the integration imaging 3D display device based on backlight,
Rationally setting pinhole array thickness, so that the light by each pin hole only illuminates corresponding image primitive, and will be in pinhole array
The hole wall of pin hole is set as light-absorption layer, prevents light by other image primitives of hole wall indirect illumination, to eliminate crosstalk；By needle
Hole array is set as reflective layer close to the face of backlight, to improve optical efficiency.

Spacing；
The thickness of pinhole arraytAre as follows:
(1)
Wherein,pIt is the pitch of pin hole and image primitive,wIt is the aperture of pin hole,gIt is between pinhole array and display screen
Away from；The hole wall of pin hole is light-absorption layer in pinhole array；Display screen is for showing image primitive；Each image primitive is all passed through correspondence
The light of pin hole illuminates, and only illuminates corresponding image primitive by the light of each pin hole, to eliminate crosstalk；
The horizontal viewing visual angle of integration imaging 3D display device based on backlightθ 1With vertical viewing visual angleθ 2It is respectively as follows:
(2)
(3)
Wherein,mFor the number of pin hole in horizontal direction in pinhole array,nFor pin hole in vertical direction in pinhole array
Number,lFor viewing distance.
Preferably, pinhole array is reflective layer close to the face of backlight.
Micro- pattern matrix and pinhole array include 10 × 10 units, wherein 10 units, Vertical Square in horizontal direction
The pitch of upward 10 units, pin hole and image primitive ispThe aperture of=10mm, pin hole isw=2mm, pinhole array and display
The spacing of screen isg=2mm, viewing distance arelThe thickness of pinhole array is then calculated in=100mm by formula (1)tFor 1mm, by formula
(2) and (3) horizontal viewing visual angle is calculated and vertical viewing visual angle is 126 °.
