Description
Technical field
The application is related to 3D display field, in particular to a kind of 3D display device.
Background technology
The general principle of bore hole 3D display is the refraction effect of the occlusion effect or lenticular sheet using slit grating
Deng guiding light, making eyes that 2 width be respectively seen has the picture of parallax information, so as to produce the effect of stereoscopic vision.Such as profit
Acted on the refraction light splitting of lenticular sheet, the pixel of the 2 width patterns with parallax information is divided into several columns, with 2 width
The pixel of same position (relative to the position of every width pattern) is classified as one group in image, pixel column parallel to cylindrical mirror length direction,
Its position is arranged on a lens pillar near focal point, and so 2 pixel columns project a left side respectively through same lens pillar
Right eye, several pixel column groups into the image with parallax information may finally be formed respectively on the eyes retina of left and right, then
Handled through brain system and obtain parallax information and form stereoscopic vision.
Normal naked eye 3D display device can show 2 width anaglyphs, and this 2 width image is commonly referred to as by lens pillar 2'(
For 1 figure 01' and 2 figure 02', and pixel column corresponding to 1 figure 01' and 2 figure 02' is referred to as the first pixel column 11' and the second pixel column
12') occur in viewing space-alternating, if beholder's left eye sees that 1 figure 01', right eye see 2 figure 02', can just be closed by brain
Into depth of field sense, so as to experience stereoscopic vision, but actually beholder is easy to make left eye because of slightly moving for head
See that 2 figure 02', right eye see 1 figure 01', brain experiences the depth of view information of mistake, and so as to cause spinning sensation, reduction uses body
Test, see Fig. 1.
Prior art improves this problem using multiple views scheme, i.e., n width (n ＞ 2) is had into regarding for continuous parallax information
Poor figure is projected in space, human eye is seen that continuous several width have the image of continuous parallax in a larger scope,
Namely the head of people can persistently watch 3D stereoscopic picture planes in a larger scope.
Compared to the scheme of 2 width disparity maps of display, the program is to take the pixel in the n width patterns with continuous parallax information
Successively with every n pixel row for one group, for pixel column parallel to cylindrical mirror length direction, its position is arranged on a lens pillar focus
Near.As shown in Fig. 2 by taking n=5 as an example, there is the pixel column of image of the continuous parallax of 5 width respectively successively with 5 for one group, 5
Individual pixel column is the first pixel column 11', the second pixel column 12', the 3rd pixel column 13', the 4th pixel column 14' and the 5th picture successively
Element row 15', so 5 pixel columns project viewing space in a manner of continuous arrangement through same lens pillar 2' respectively, if
Dry pixel column groups into every width image with parallax information may finally be formed respectively on the eyes retina of left and right, observer
When 100 head is persistently moved in a larger scope, 1 figure 01', 2 figure 02', 3 figure 03', 4 figures can be watched successively
04', the figure 05' ... of 5 figure 05' ..., 1 figure 01' ... 5, therefore, the head of observer 100 can persistently be seen in a larger scope
See 3D stereoscopic picture planes, significantly reduce the chance for the parallax that reversed order is seen as 2 width disparity maps, improve viewing sense
By.
But due in conventional multi-view scheme, designing several viewpoints, as shown in figure 3, just must be by 1 figure 01', 2
Figure 02', 3 figure 03', 4 figure 04', lens cover in several pixel columns for belonging to different points of view image corresponding to 5 figure 05', because
This, the pixel column of lens pillar covering is more, causes circular arc chord length to increase, and to ensure the constant of focal position, must just increase
The rise of big lens pillar, as shown in Figure 3.Because existing lenticular sheet production decision is using imprinting moulding technology (heat
Pressure or UV impressings), rise is higher, easily causes lens surface structure to produce to collapse in moulding process and cause face type in production
The problems such as error and/or the bad impressing demoulding.Meanwhile rise is higher, material is more spent by production, cause production cost compared with
It is high.
Also, found simultaneously by theoretical calculation and experiment, the pixel column of lens pillar covering is more, identical most in guarantee
On the premise of good viewing distance, the distance of plane where plan range display panel pixel array where lens pillar optical centre
Bigger, this can directly result in the increase of final product thickness and weight.
The problem of similar, remains on presence in scene of the slit grating (Barrier) as 3D optical elements.Slit light
Grid include shading region and the transparent area of multiple arrangements interlaced with each other, and adjacent shading region and a transparent area form " one
Cycle ", that is, a slit grating is formed, for example in the prior art, a cycle here covers multiple pixel columns, therefore
On the premise of ensureing identical viewing ratio, where plan range display panel pixel array where slit grating optical centre
The distance of plane is still larger, and this also results in the increase of product thickness and weight.
The content of the invention

Figure 15 show the energy distribution curve that the 3D Optical devices are simulated using optical software, and liquid crystal display panel is shown
Specially treated artwork master, receiving plane are placed at display panel 1998mm, gather the energy datum value of receiving plane, system
The curve map shown in Figure 15 is made, wherein all energy datum values make normalized, abscissa is on receiving plane in figure
For point apart from the position at receiving plane center, ordinate is the homogeneity of energy, and curve L1 represents the energy that the first viewpoint receives, curve
L2 represents the energy that the second viewpoint receives, and curve L3 represents the energy that the 3rd viewpoint receives, and curve L4 represents that the 4th viewpoint receives
Energy, curve L5 represents the energy that the 5th viewpoint receives, and curve T represents the gross energy that receives, and the curve of gross energy is relatively flat
It is sliding, it can be seen that the 3D effect of the optics module central vision is preferable, and overall energy homogeneity is preferable.
As can be seen from the above description, the application the above embodiments realize following technique effect：
In the 3D display device of the application, the optical unit in 3D optical elements corresponds with pixel column, i.e., each picture
Optical unit corresponding to the light process of image corresponding to element row projects corresponding vision area so that on the retina of the right and left eyes of people
The image with parallax information is formed, the 3D display device causes a lens pillar to cover multiple pixel columns, Jin Erwu
Each lens pillar need to be caused to have larger mistake high, properties of product caused by avoiding larger mistake height are poor and cost is higher
The problem of.
The preferred embodiment of the application is the foregoing is only, is not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair
Change, equivalent substitution, improvement etc., should be included within the protection domain of the application.
