Kaplan氏之「視差屏障理論」（Theory of parallax barriers)，出自期刊 SMPTE Vol. 59, No.7, pp 11-21, 1952年7月’敘述使用屏障於3D顯像之基本知識。201027122 VI.

[Prior Art] Regarding the stereoscopic optical element, in particular, an optical element composed of a parallax barrier, its discussion has existed for a long time.

Since this technique is for the first time, most of the stereoscopic display systems are partially shifted to the vertical direction due to loss of horizontal direction resolution occurring by simultaneously displaying a plurality of images (at least two 'especially two or more). The disadvantage here is that high light loss occurs in all barrier methods. In addition, when the viewer moves sideways, the stereo contrast will change from close to 100% to about 50%, and then rise to 100%, which causes the 3D image quality to fluctuate in the viewing space. US 2006/0051109 A1 (Lim et al.) proposes a method of manufacturing a 3D glory screen which aligns a device that produces a 3D image (e.g., a lens or screen) in front of a screen and then performs an adhesive bond when correcting the alignment. This place 098135047 4 201027122 shows no black line, it will be seen by the operator or camera. Here's the lack of ':, when the hand is aligned', only black lines or black faces are used, and the required method of advancement cannot be achieved. At least one left image and one right image are used as the pair (four) image, which has a forest image. Sometimes there are all white faces and all black faces, so it is necessary to evaluate two separate test charts, that is, left and right images. DE 102 52 830 B3 (Maly_M〇tta) proposes a flat screen ❹ body display adapter (especially a cylindrical lens type glory) that is automatically calibrated with a photo-electrical sensor. The test chart made by this office cannot be judged, so the calibration quality cannot be evaluated. The factor that determines the quality of the 3D display is the correct alignment of the 3D optics to the video playback device or panel. Here, the deflection of the vertical line in the middle of the image plane must be accurate (preferably one or several angular points) and the 3D optical element must be parallel to the panel. The lateral and vertical movement of the 3D optical element only has an effect on the so-called jump point, ie, in many cases, no importance.

SUMMARY OF THE INVENTION 098135047 5 201027122 The object of the present invention is to provide a method for positioning a rotating optical component to a video playback device, which can be used as a video playback device suitable for stereoscopic imaging with a simple tool, so that it can be used in a relatively short period of time. Highly repeatable and accurate alignment. The object of the present invention is to provide a video playback device suitable for stereoscopic imaging by using a method of arranging an optical component to a video playback device having raster pixels x(i, j) of row i and column j, including Steps: On the video playback device, the first priority direction is indicated with respect to the raster consisting of row i and column j; the second priority direction is indicated on the optical component; the optical component is positioned in front of the video playback device' And wherein the first and second preferential directions are aligned with each other according to a preset translation and/or a preset rotation, so that the optical component is accurately aligned with a tolerance of a maximum of three minutes according to the preset rotation. Align the video playback device. A special invention of the present invention is to position the optical element in front of the image playback device (barrier screen, cylindrical lens screen, lens grating, patterned surface, etc.) into two steps. Therefore, unlike the prior art, the optical component is placed in front of the video playback device and then aligned using a test pattern. The present invention defines itself as the first priority direction during or after the manufacturing process of the video playback device. At the same time, a second preferential direction is defined on the optical component, and the optical component can be directly placed on the video playback device according to the first preferential direction. Therefore, in the positioning step, the optical component is aligned with the image-casting device, and almost 098,135,047 6 201027122 can be automated. The first preferential direction is parallel to the direction of row i or column j but can be in other directions. In an advantageous design the optical element consists of an active or passive parallax barrier screen which is inclined at an angle a with respect to the horizontal direction or as a stepped transparent and opaque portion. The optical element can also be composed of a cylindrical lens screen, an active or passive holographic optical element (HQE), an active or (four) Wei grating, an image surface or a prism grating. The second preferred direction indication on the optical element of the present invention is an optically preferred position relative to the surface pattern of the optical element. In the case of the parallax barrier, the optical image is buried as a transparent and opaque portion 'which can be inclined at an angle a with respect to the second preferred direction, for example, the ice direction. If the system and the opaque part are rectangular and staggered with each other, and (4) read, there will be - phase _ money, then the compensation line generated by the transparent new point - the transparent part of the wealth ^ the recorded distance is (5) - and the second priority direction The angle (4) is the angle a. When the element is a cylindrical lens type screen, the optical preferential direction of the optical pattern is, for example, the main propagation direction of each cylindrical lens on the optical element. When the pattern is a raster shape, it is parallel to one side. Because of the optical mode of the optical component, the force-sensitive door cooperates with the positioning of the present invention, such as in the space and/or time of the structure of the phase-locked wire component 2 in the image playback device, in pixels per ton, chest-view and scene / or at least n=2 098135047 201027122 = ; 景?

Therefore, in the future, it can be clearly stated that (4) the playback device can be converted to the 3D 098135047 201027122 state by the alignment of the optical components. In addition, the pixel x(i,j) may be an individual (7) such as a color sub-pixel (R, G or B), or a full-color image f, G or B) agglomerate (eg 'RG, GB or RGBR, etc.) RPR 1, and the full-color pixels of the towel refer to brain color sub-pixels, that is, /, white mixed structure of colors, and - according to image generation technology - true full-color pixels, such as projection screens are often used. The learning component is typically permanently placed on the video playback device at a defined distance S' after being positioned in front of the video playback device. However, detachable connections can also be used. The parallelism between the image playback device and the optical component, that is, the parallelism between the two planes of the image playback device and the optical component, is achieved by, for example, directly attaching or adhering the optical component to the image display surface of the image playback device. . If the optical element consists of a parallax barrier screen, a spacer can be provided at the edge or a tape that can be held a defined distance. The video playback device can be, for example, a color liquid crystal display, a plasma display, a projection screen, an LED screen, a 〇 LED screen, an SED screen, a VFD screen, or a corresponding panel of the above screen or display. It can also be used for other video playback devices. If the optical element is constituted by a parallax barrier screen, it can advantageously be composed of a glass substrate having a barrier pattern. The barrier pattern can be composed of #光 and developed photographic film which is bonded to the back side of the glass substrate so that the emulsion layer of the photographic film does not face the glass substrate. It is also possible to make the transparent portion of the photographic film consist of the color printed on the glass substrate. 098135047 9 201027122 Optical elements advantageously include elements that reduce the reflection of interfering light. An interfering optical anti-reflective layer. Less image playback skirts - an outer frame, which is for example made of metal. At or after the manufacture of the discharge device, at least two holes or two projections are provided on the outer frame and the first priority direction is indicated on the video playback device. The connection between the center points of the two two protrusions is the first priority direction. - the optical element (4) is provided with at least two pin fasteners (for the purpose of providing holes) or holes (for the outer frame with protrusions), so that the optical component is positioned in the video playback device with a simple fit In front. The connecting lines of these define the center point of the second twin + the second sub-hole.. 'Priority direction. In this way, focus on the light wind: Ι::::ΙΓ-3- or align the components, for example, in the video player insert. A ten-hole shaped hole 'which can be connected to a corresponding cross-shaped video playback device I - the first direction is made up of the outer frame - the first one is made of metal, and the first excellent outer frame is seen Invisible bearing:: Table = 2, for example, 1 - is set to be in the period of the imperial (face straight) contact to achieve the above ·, alignment, only in the repeated width or height of the integer multiple of the usual For a pixel x(i,j) positive position or place, but the relative position of the first and second priority 98135047, its 201027122 can be defined by a vector of the same length, for example. The relative positions of the two vectors are relative to one another, including a horizontal and/or vertical movement distance, and a rotation of a predetermined angle such as zero or 90 degrees. In another design of the present invention, particularly for a laptop computer, the video playback device includes a display panel, a main frame, and a front frame. The main frame can be made, for example, of metal, and the front frame constitutes an aperture or can be made of plastic. In the first step, the display panel is placed in the main frame and aligned. In the second step, the main frame and the © display panel are placed in the front frame and aligned. The first priority direction is indicated on one of the edges of the front frame. In the next step, the optics are resized so that they can be placed in the front frame. One of the edges of the optical element, when placed in the front frame, abuts its corresponding edge and constitutes a second preferential direction, in particular, relative to the optically preferential direction on the optical element. In this way, the image playback device and the optical components can be automatically aligned during assembly positioning without the need to use the test pattern in a cumbersome manner. In order to increase the accuracy with redundancy, one of the front frames or more of the other edges can be defined with other priority directions, and other priority directions can be defined on the optical components. The positioning step of the optical element can in principle be performed manually by the operator or automatically by the robot or by a mixture of the operator and the robot.

Other designs of light materials have also been proposed in some of the above documents, for example, cylindrical lens screens are all familiar to those skilled in the art. The features of the present invention will be described in detail below based on the embodiments. [Embodiment] ° 〇 All figures are not to scale and are merely illustrative. Especially the angular size. 1 shows a schematic structural view of a video playback device 1 suitable for stereoscopic imaging. The viewer 3 passes through an optical S component 2, here for example, a parallax barrier screen, which is hereinafter referred to as 2, while viewing the image broadcast device 1 And get a three-dimensional feeling. The video playback device 1 and the parallax barrier screen 2 are substantially parallel to each other and separated by a distance s. The parallax screen (4) screen 2 can be as described above, for example, in the document of Jp 〇 8 _ _ _ 5, the image playback device 1 can be used to simplify the multi-directional image, as described above. Before the method of the present invention is carried out (state not shown), although the video playback device 1 and the parallax screen 'curtain 2' are present, the alignment is not reduced as in gj, that is, there is no 3D sense. To produce a video playback device suitable for stereoscopic imaging, that is, to position the optical component 2 with the image playback device i having row i and column j raster pixels, the method of the present invention can be used, which includes the following steps: 098135047 12 201027122 On the video playback device 1, the first priority direction is indicated with respect to the grating consisting of row i and column j; the second priority direction is indicated on the optical element 2; the optical component 2 is positioned on the video playback device 1 front, and the first and second preferential directions are transferred to a preset relative position, according to the relative position of the optical element 2 to the rotational position of the video playback device 1, with the highest tolerance of the minute, accurately The optical element 2 is aligned with the video playback device 1 having the pixel x(i, j). In other words, that is, the optical element 2 is positioned in front of the video playback device 1, and wherein the first and second priority directions are aligned with each other in accordance with a preset translation and/or a predetermined rotation. Therefore, the optical element 2 is aligned with the image playback apparatus 1, in particular, the preset rotation of the tolerance is at most a triangle, and a stereoscopic feeling can be produced. Figure 2 shows a video playback device 1 having row i and column j raster pixels x(i,j). The image playback device 1 has an outer frame 6' which is made, for example, of metal. When the video playback device 1 is manufactured or after, two holes 4a and 4b are provided on the outer frame 6, and the connection line at the center point defines the first priority direction, and the first priority is marked on the video playback device 1. direction. The optical element 2 is oppositely provided with at least two latching members 5a, 5b (in the case where the outer frame 6 is provided with holes 4a and 4b)" as shown in FIG. 3, so that the connecting line at the center point defines a second priority. The orientation is such that the optical element 2 is positioned in front of the video playback device 1 with a simple fit in accordance with the defined relative position. For example, 098135047 13 201027122, the optical element 2 is particularly effectively aligned. The first priority direction is preferably parallel to row i or column j, i.e., in the direction. The indication of the second preferential direction on the optical element 2 is converted relative to the preferred direction of the optical structure of the optical element. The optical structure of the parallax barrier screen is, for example, a transparent and opaque portion along the optically preferential direction, which can be tilted by an angle a for the second preferred direction. When the optical element 2 is composed of a cylindrical lens type screen, the preferential direction of the optical structure is, for example, the main propagation direction of each cylindrical lens of the optical element 2, which is also inclined by an angle a to the second preferential direction, and the second priority direction is described. It is defined by the optical element 2, i.e. at least two snap members 5a, 5b on the cylindrical lens screen. The optical element 2 can be constructed of a cylindrical lens screen as described, as shown in FIG. The cylindrical lens 7 of the dome lens is shown schematically. The method of the present invention also allows the first and second preferential directions to be transferred, i.e., in parallel relative positions, i.e., in parallel with each other. Other designs are also possible. Since the optical mode of the optical component cooperates with the positioning of the present invention, if a scene is displayed on the image playback device 1 simultaneously or sequentially in a space and/or time corresponding to the structure of the optical component 2, a pixel is displayed in the pixel x(i, j) And/or at least n=2 images of the scene, then the stereoscopic image is achieved on the video playback device 1. The number η>1' is, for example, 2, 3, 4, 5, 6, 7, 8, 9 or 16, for comfortable and flexible stereoscopic imaging, which can be matched with conventional methods such as a parallax barrier (see above) Literature) or cylindrical lens method, which is familiar to the knowledge of professionals in the field 098135047 14 201027122. The image A(k) of the 3D image played back later on the image reproduction device 1 having the aligned optical element 2 is preferably a scene and/or scene view, such as different other 3D imaging methods. . In the embodiment, the pixel (four) is equal to each color: under-pixel (R, G. In most cases, the optical element 2 is permanently set in the image with a defined distance s after being positioned on the video playback device ι The playback device i can be, for example, a color liquid crystal display, an OLED screen, or a panel of the above-described screen or display. The optical element 2 can be a parallax barrier screen that can advantageously be constructed of a glass substrate having a barrier pattern. The pattern may consist of an exposed and developed photographic film that is bonded to the back side of the glass substrate. The emulsion layer of the photographic film preferably does not face the glass substrate. The optical element 2 advantageously comprises an element that reduces interference with light reflection, preferably at least An interferometric optical anti-reflection layer. The positioning step of the optical element 2 can in principle be performed manually by the operator, automatically by the robot, or by the operator and the robot. In another design, especially for portable The computer, video broadcast 1 device scoop includes a display panel, a main frame and a front frame. The main pivot can be, for example, metal The front frame constitutes the aperture and can also be made of plastic. The first step _ towel, _ the display panel is placed in the main frame and aligned. In the second step, the main push age >, the display panel is placed The front frame is aligned and the first priority direction is marked on one of the edges of the front pivot. In the next step, the optical element is sized 'so that it can be placed in the front frame 098135047 15 201027122. One edge of the optical element is placed When entering the front frame, it abuts its corresponding edge and constitutes a second preferential direction, in particular, with respect to the optical preferential direction on the optical element. Thus, the image playback device and the optical element can be automatically aligned during assembly positioning. There is no need to use the test chart in a cumbersome manner. In order to increase the accuracy with redundant code, one or more other edges of the front frame may be defined with other preferential directions, and other preferential directions may be defined on the optical element. Advantages of the Invention In particular, the present invention enables optical components such as a parallax barrier screen or a columnar screen to be aligned with a video playback device with high reproducibility and accuracy in a short period of time. A video playback device that produces a stereoscopic display. Compared to the prior art, the optical component is first positioned in front of the video playback device and then aligned using a test pattern. The method of the present invention omits the positioning of the optical component in front of the video playback device. The steps and the test chart (and the wiring and wiring of the video playback device) are used in a large amount of time. The present invention can use different size video playback devices, so that the flexibility can be manually, Automatic or semi-automatic operation. Therefore, the present invention can use simple and general tools. [Simplified Schematic] FIG. 1 is a schematic structural view of a video playback device suitable for stereoscopic imaging.
