In the exploration of stereoscopic image technology directly with the naked eye, and in recent years, substantial progress has been made. These technologies are collectively referred to as full-true stereo display technology. In 1903, scientists discovered that "the parallax creates a three-dimensional, the principle of the 'Luo Yue?" is the difference between the two eyes, the two eyes see the world from different angles, the object of the left eye is the same as the right eye - the object There is a difference. Because the shadows of the objects seen by the two eyes are slightly different, so the way of describing the scenes is not the same, the brain roots have two subtle differences, and the other is different. Processing, forming a precise two-dimensional object and the stereoscopic feeling of the object in the #景_定& 巧" / 木反▲ (4) Λ All work is at least for each scene: right two or two representative left eye Seeing 'the other - Zhang is the right eye to see the two images called the stereo weight # image (7) (10) 1328127 Μ); and the stereoscopic (four) system must make the left eye only see the left eye image, right eye Only the right eye image can be seen.彳September 27th 'Sharp and Sharp European Institute (UK) f cloth development successfully without the need for special glasses can also see the stereoscopic image sub-can switch from two-dimensional to two-dimensional display, the picture is summer The 2D/2D switchable display I set the 3D display schematic diagram.

The film driving device 24 includes a springback 242, a motor driving unit 246, and a _=recovery force unit disposed on the liquid crystal display side: the film array device is connected at the end of the film, and the film is held. The array device is pre-tightened, and the motor driving unit is placed on the other side of the liquid crystal display and is connected to the other end of the film array η to provide the rotational power of the film array skirt 22, which is 249 And the motor driving unit 246 is disposed on the same side of the liquid crystal display 21 to lock the rotation of the film array device 2 2 such that a certain area stays directly above the liquid crystal display 21; the height control device 26 is placed in the film array Between the device 22 and the liquid crystal display 2, the two ends of the liquid crystal display 21 are adjacent to each other, and the relative heights of the film array device 22 and the liquid crystal display 21 are controlled. 1328127 Please refer to the fifth figure, which is a schematic diagram of the three-dimensional display principle of the first embodiment of the three-dimensional/two-dimensional switchable display device of the present invention. The left and right eyes of the observer are marked with 286 and 288 respectively, and the plurality of pixels are 25-type liquid crystal display. The image unit of the surface of the 21, the period of the halogen is 32, which is divided into the L group and the R group, and the L group and the R group are alternately distributed, and the adjacent L group and the R group are displayed in the three-dimensional display. After the operation, two images of the object seen by the observer's eyes are simulated. The period A of the binary grating region 222 is approximately equal to the period d of the pixel 25, and the P is the observer's eye from the binary grating region 222. The distance between the Η-based binary grating region 222 and the 昼素25, the 0-system observation angle is the angle at which the observer can recognize the stereoscopic feeling, and the following relationship can be obtained from the geometric relationship: H=d/(2tan (6> /2» Ρ Θ =5-10cm where P 0 represents the distance between the eyes of the observer, usually 5-10cm. For example, the distance between the eyes of the observer is 5cm, and the observer's eye is from the binary grating area. The distance P of 222 is 35cm, and the valence of 25 cycles d is 280烊m, then the above relationship can be obtained. The distance between the element grating region 222 and the halogen element 25 should be controlled to be about 2 mm. During operation, the height control device 26 adjusts the distance from the binary grating region 222 to the pixel 25 to the required height, and the binary grating region 222 plays. 8 1328127 The function of the parallax barrier is such that the image of the L group can only be transmitted to the left eye 286, and the image of the R group can only be transmitted to the right eye 288. The three-dimensional/two-dimensional switchable display device is a schematic diagram of the two-dimensional display principle of the first embodiment. When the two-dimensional display is required, the motor driving unit 246 drives the film array device 22 to rotate, and the completely transparent region 221 is located directly above the liquid crystal display 21. The motor driving unit 246 stops driving, and the locking unit 249 locks the film array device 22, so that the completely transparent region 221 is fixed directly above the liquid crystal, and at this time, the image of each pixel 25 simultaneously enters the left eye 286 and Right eye 288, to achieve 3D to 2D switching display. Please - and refer to the first to sixth figure, the 3D / 2D switchable display 2 2 from 2D display to 3D display switching process such as = first 敎 single It 249 unloaded, followed by Spring restoring force = where 242 drives the film array device under the elastic restoring force, the binary grating region 222 is located directly above the liquid crystal display 21 = the locking unit 249 locks the binary grating region 222 to be fixed to the liquid: 曰 display g21 positive Above, that is, from the two-dimensional display to the three-dimensional display: the switching process. The three-dimensional/two-dimensional switchable display device 2 follows the same principle from the three-dimensional non-two-dimensional display* switching process, and at the same time drives the thin film array device 22 to rotate. The force comes from the motor% moving element 246. 丄328127 Please refer to the seventh figure, which is the plane of the second embodiment of the present invention device _ Li 2 ^ two-dimensional switchable display switching display two sides are not intended 'the three-dimensional / two The dimension available for display device 3 is basically the same as the second map 2, which is also coated with the VII 70 _ 70 Wang Qianxian area 321 and the 箬 箬 设 兀 兀 342 342, etc. Dry # ¥. ^ 丨 』 』 』 』 』 』 』 』 』 』 』 』 』 』 』 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该The invention has a three-dimensional/two-dimensional switchable display device which adopts a film array with a grating area and a lens array.
