Description
Technical field
The utility model is the optical devices that have liquid crystal lens (Liquid Crystal Lens) about a kind of, especially in regard to a kind of optical devices, and different electrode patterns are set in its double-deck liquid crystal lens and not apply bias voltage and to apply bias voltage and reach and switch two dimension (2D) flat image and integrated photography (Integral Photography) stereopsis with double-deck liquid crystal lens.
Background technology
Generally speaking, the display technique of three-dimensional (3D) stereopsis is the eyes via the user, and realizes according to the principle of stereoscopic vision.Because human eyes each other at a distance of about 5 ~ 7 centimeters distance, therefore have binocular parallax, promptly since the alternate position spike between the right and left eyes apart from causing two images of being seen real for having the different images of nuance.Difference between the image that the right and left eyes that this eye position gap is caused is watched is to be called binocular parallax.Therefore, making the 3D holographic display device traditionally is to utilize the basis of binocular parallax to design, and allows user's left eye only watch to the image of left eye and right eye is only watched the image to right eye.
Utilize binocular parallax to produce relief display mode and how need wear special utensil and reach, common method comprises modes such as utilizing polaroid glasses, red indigo plant (green) glasses, shutter glasses and helmet-mounted display and reaches.So, no matter all needing the user to wear special utensil, above-mentioned display packing cost height just watched stereopsis, thereby the sensation that what all can bring inconvenience for the user, therefore, focus on then that in recent years exploitation does not need to wear the bore hole formula 3D 3 d display device that any special utensil can watch stereopsis.
And, do not need to wear bore hole formula 3D 3 d display device that any special utensil can watch stereopsis and design with the basis of binocular parallax and then be called parallax method bore hole formula 3D 3 d display device.This kind 3D 3 d display device is for the place ahead in the light source array of display (for example LCD) veils such as disparity barrier (Parallax) or grating to be set, and wherein the light source array also transmits left-eye images and right-eye image in regular turn, makes that user's right eye is seen right-eye image through disparity barrier allows user's left eye see left-eye images.So, see through left eye and see that left-eye images and right eye see the user of right-eye image, it is stereopsis that its brain can merge left-eye images and the right-eye image seen automatically.
Yet above-mentioned parallax method bore hole formula 3D stereo display method is to exist a little shortcoming, for example: when light is regional by the linear fringe of the black of disparity barrier, can be covered owing to light, thereby it is over half approximately to cause brightness to reduce.In addition, when this technology is applied to liquid crystal panel, because it is right that the picture element of general liquid crystal panel can be divided into the image of several odd number picture elements and even number picture element, being able to allowing stereopsis be watched at more perspective, thereby below when making the resolution of the 3D stereopsis that presented become the 2D flat image half.Moreover, when carrying out stereo display,, just may allow the image that projects left eye originally be projected to right eye when the user moves the position at a visual angle with the method for binocular parallax, cause " pseudoscopy ".Therefore, parallax method bore hole formula 3D 3 d display device often can't provide many people to view and admire simultaneously.
And, except the made parallax method bore hole formula 3D 3 d display device of the mode of utilizing binocular parallax, need not wear any special utensil can view and admire the technology of stereopsis and also comprise integrated photography (Integral Photography is designated hereinafter simply as IP) stereo display technique.
The IP stereo display technique is to propose 1908 Christian eras, main technical principle is to see through fly lens (Fly ' s – Eye Lens) with the image information under the record different visual angles, wherein fly lens is the small convex lens array that similar fly's eye is arranged in a combination, be that row semisphere lenslet is arranged in the plane just, be used for photographing or display image one.Therefore, the IP display technique is to be divided into two big steps generally.At first, see also Figure 1A, utilize fly lens 103 shot objects 101 and obtain the image information 107 of different visual angles with image capture unit 105; Then, see also Figure 1B, after obtained image information 107 carries out optical processing via display device 109 and fly lens 103 again, can present the 3 D stereoscopic image 110 of captured object.
In addition, the optical design demand according to different also can be provided with optically focused convex lens 120 in fly lens the place ahead, as shown in Figure 2.Or, because the production method of fly lens is difficulty comparatively, therefore directly do not use fly lens, and repeatedly put the effect that reaches fly lens with horizontal direction and vertical direction respectively with two lens pillars, as shown in Figure 3, first lens pillar 131 is put with vertical direction, and second lens pillar 132 is put the effect that reaches fly lens with horizontal direction.Because lens pillar is easier to make compared to fly lens, therefore can reduce the cost of making lens.
So, utilize above-mentioned optical design to reach the acquisition of stereopsis of IP display technique or fly lens, optically focused convex lens and the lens pillar that show to need uses all is to make in modes such as ejection formation, mold and hot pressing usually.Therefore, the design of optical devices such as the display device of these a little fly lenses of application configuration, optically focused convex lens or lens pillar or camera can't allow the user take out this a little lens voluntarily usually, so, the user needs to carry out the acquisition of 2D flat image information or when showing in using, then can't use optical devices to carry out with these a little fly lenses or lens pillar, and the optical devices that need to change other just can carry out the acquisition or the demonstration of 2D image information, cause the inconvenience in the use.
Therefore, need badly and want a kind of different demands that can capture or show 2D flat image or IP stereopsis, reach the optical devices that switch 2D flat image and IP stereopsis easily according to user's desire.
Summary of the invention
