立体影像显示装置Stereoscopic image display device

技术领域technical field

本发明是有关于一种立体影像显示装置，尤有关一种运用普菲力克效应(Pulfrich effect)产生立体显示效果的立体影像显示装置(3D imagedisplay)。The present invention relates to a three-dimensional image display device, in particular to a three-dimensional image display device (3D image display) which utilizes the Pulfrich effect to produce a three-dimensional display effect.

背景技术Background technique

图1为一示意图，显示公知一自动立体影像显示装置(autostereoscopicdisplay)100的设计。如图1所示，该影像显示装置100包含一液晶显示面板102、液晶光阀(LC shutter)104、及背光106。液晶显示面板102具有显示左眼影像数据的多个像素单元108、及显示右眼影像数据的多个像素单元112，且像素单元108及像素单元112是以交互间隔排列方式配置。再者，左眼及右眼影像资料例如可利用两台水平并列安置的摄影机，分别代表人的左、右眼同步拍摄出两个画面制作出。液晶光阀104作为产生左右眼视觉分离效果的视差光件，当液晶光阀104呈开启状态(ON)时，施加电压可改变部分液晶分子的配列状态而形成多个不透光区块114，借由不透光区块114与液晶显示面板102的像素单元108、112错置产生的视差效果，当由背光106发出的光线通过液晶光阀104与液晶显示面板102之后，可使观察者116的左眼仅能看到左眼影像资料而右眼仅能看到右眼影像资料，而产生立体三维(3D)影像显示效果。FIG. 1 is a schematic diagram showing the design of a conventional autostereoscopic display device (autostereoscopic display) 100 . As shown in FIG. 1 , theimage display device 100 includes a liquidcrystal display panel 102 , a liquid crystal shutter (LC shutter) 104 , and abacklight 106 . The liquidcrystal display panel 102 has a plurality ofpixel units 108 for displaying left-eye image data and a plurality ofpixel units 112 for displaying right-eye image data, and thepixel units 108 andpixel units 112 are arranged alternately at intervals. Furthermore, the image data for the left eye and the right eye can be produced by using two cameras arranged horizontally side by side to represent the left eye and the right eye of a person respectively to capture two images synchronously. The liquidcrystal light valve 104 is used as a parallax optical element to produce the visual separation effect of the left and right eyes. When the liquidcrystal light valve 104 is in an open state (ON), applying a voltage can change the arrangement state of part of the liquid crystal molecules to form a plurality ofopaque blocks 114. Due to the parallax effect produced by the dislocation of theopaque block 114 and thepixel units 108 and 112 of the liquidcrystal display panel 102, when the light emitted by thebacklight 106 passes through the liquidcrystal light valve 104 and the liquidcrystal display panel 102, theobserver 116 The left eye can only see the image data for the left eye and the right eye can only see the image data for the right eye, thereby producing a stereoscopic three-dimensional (3D) image display effect.

图2为一示意图，显示利用快门眼镜(shutter glasses)产生三维效果的另一公知立体影像显示装置200。于该设计中，当背光206发出的光线通过液晶显示面板202后，左、右眼在不同的时间点可分别看到左眼影像资料及右眼影像资料而产生视觉分离效果。交替显示的左、右眼影像资料必须经由快门眼镜204与一控制电路(未图标)同步操作，如图3所示，利用一切换信号控制快门眼镜204左眼及右眼的开启(On)与关闭(Off)，当该切换时序与液晶显示面板202的接收影像(左眼影像资料或右眼影像资料)同步后，显示左眼影像数据时快门眼镜204会遮蔽右眼的视线；反之显示右眼影像数据时快门眼镜204会遮蔽左眼的视线，如此左、右眼影像快速交替显示再借由视觉暂留效应可产生立体视觉效果。FIG. 2 is a schematic diagram showing another conventional stereoscopicimage display device 200 that uses shutter glasses to produce a three-dimensional effect. In this design, when the light emitted by thebacklight 206 passes through the liquidcrystal display panel 202, the left and right eyes can respectively see the left-eye image data and the right-eye image data at different time points to produce a visual separation effect. The alternately displayed left and right eye image data must be operated synchronously with a control circuit (not shown) through theshutter glasses 204. As shown in FIG. Closed (Off), when the switching timing is synchronized with the received image (left eye image data or right eye image data) of the liquidcrystal display panel 202, when the left eye image data is displayed, theshutter glasses 204 will block the sight of the right eye; otherwise, the right eye will be displayed. Theshutter glasses 204 will block the sight of the left eye when the eye image data is displayed, so that the left and right eye images are quickly displayed alternately and a stereoscopic effect can be produced by the persistence of vision effect.

图4为一示意图，显示公知另一立体影像显示装置300的设计。如图4所示，立体影像显示装置300包含一普菲立克立体眼镜304，该立体眼镜304其中一片镜片(例示为左眼镜片)另包含一中性滤光片(neutral filter)，使左右两个镜片的透光率不同，借以产生普菲立克效应。普菲立克效应是一种利用大脑对于阴暗刺激的认知比明亮刺激稍微迟缓而形成的光学幻觉，因此，当背光306发出的光线通过液晶显示面板302后，因为图4所示的左眼镜片较暗，虽然透过镜片两眼都会看到相同的影像，但左眼传输影像给大脑的速度会比较慢，如此可构筑出实际上并不存在的空间深度而产生三维效果。如图5所示，利用一切换信号控制普菲立克立体眼镜304左眼及右眼的开启(On)与关闭(Off)，当该切换时序与液晶显示面板302的接收影像(左眼或右眼)同步后，显示左眼较暗影像资料时右眼视线被遮蔽，反之显示右眼一般亮度影像资料时左眼的视线被遮蔽，如此左、右眼所感知的明暗影像快速交替变化，仅需写入针对左右眼均相同的二维影像资料而不需另外准备独立的左右眼视差影像画面，即可产生立体视觉效果。FIG. 4 is a schematic diagram showing the design of another conventional stereoscopicimage display device 300 . As shown in FIG. 4 , the stereoscopicimage display device 300 includes a Pflickstereoscopic glasses 304, wherein one lens of the stereoscopic glasses 304 (example is a left eye lens) further includes a neutral filter (neutral filter), so that the left and right The light transmittance of the two lenses is different, so as to produce the Pfeiffer effect. The Pflick effect is an optical illusion formed by using the brain's cognition of dark stimuli to be slightly slower than bright stimuli. Therefore, when the light emitted by thebacklight 306 passes through the liquidcrystal display panel 302, because the left eyeglass shown in FIG. 4 The lens is darker. Although both eyes can see the same image through the lens, the transmission speed of the image from the left eye to the brain will be slower, so that the depth of space that does not actually exist can be constructed to produce a three-dimensional effect. As shown in Figure 5, a switching signal is used to control the opening (On) and closing (Off) of the left eye and the right eye of the Pflickstereoscopic glasses 304. Right eye) synchronization, the right eye's sight is blocked when the left eye's darker image data is displayed, and the left eye's sight is blocked when the right eye's normal brightness image data is displayed, so the light and dark images perceived by the left and right eyes change rapidly alternately, The stereoscopic effect can be produced only by writing the same two-dimensional image data for the left and right eyes without preparing independent left and right eye parallax image frames.

综合上述可知，于图1及图2所示的公知设计中，若欲产生立体视觉效果，必须预先准备左右眼各自独立的视差影像画面；而于图4所示的公知设计中，虽可利用原始的二维影像资料作为输入画面，但仍需同步化立体眼镜左右眼的On/Off切换时序与影像信号传送时序。Based on the above, it can be seen that in the known designs shown in Figures 1 and 2, if a stereoscopic effect is to be produced, separate parallax image frames for the left and right eyes must be prepared in advance; and in the known design shown in Figure 4, although the The original two-dimensional image data is used as the input image, but it is still necessary to synchronize the On/Off switching timing of the left and right eyes of the stereo glasses and the timing of image signal transmission.

发明内容Contents of the invention

因此，本发明的目的在于提供一种立体影像显示装置，其能利用原始的二维影像资料作为输入画面且不须利用快门眼镜(shutter glasses)即可产生立体视觉效果，而可大幅简化显示立体影像的驱动架构并有效降低制造成本。Therefore, the purpose of the present invention is to provide a stereoscopic image display device, which can use the original two-dimensional image data as the input picture and can produce stereoscopic visual effects without using shutter glasses (shutter glasses), and can greatly simplify the display of stereoscopic images. The driving structure of the image can effectively reduce the manufacturing cost.

依本发明的设计，一种立体影像显示装置包含一显示面板、一视差光件、及一亮度控制组件。视差光件设置于显示面板的一侧，以使一观察者透过视差光件观看显示面板时，观察者的左眼及右眼分别看到相异的一第一及一第二视域(viewing zones)。亮度控制组件设置于观察者观看显示面板的视线上，其具有对应第一及第二视域位置分布的一第一及一第二透光区，且第一及第二透光区具有不同的光透过率，使观察者左眼及右眼分别观看第一及第二视域时感知一亮度差。视差光件例如可为液晶光阀(LC shutter)、视差障壁基板(parallax barrier plate)、或柱状透镜(lenticular lens)，且亮度控制组件例如可为一液晶光阀或一滤光片基板。According to the design of the present invention, a stereoscopic image display device includes a display panel, a parallax light element, and a brightness control component. The parallax light element is arranged on one side of the display panel, so that when an observer watches the display panel through the parallax light element, the left eye and the right eye of the observer see different first and second visual domains respectively ( viewing zones). The brightness control component is arranged on the line of sight of the observer watching the display panel, and has a first and a second light transmission area corresponding to the position distribution of the first and second viewing areas, and the first and second light transmission areas have different The light transmittance enables the observer to perceive a brightness difference when the left eye and the right eye watch the first and second viewing zones respectively. The parallax optical element can be, for example, a liquid crystal shutter (LC shutter), a parallax barrier plate, or a lenticular lens, and the brightness control component can be, for example, a liquid crystal shutter or a filter substrate.

借由本发明的设计，不仅不需穿戴传统的快门眼镜因而不需进行快门眼镜切换时序与影像信号传送时序的同步化过程；另一方面，亮度控制组件可使左右眼个别视域的亮度产生差异而引致普菲立克效应，如此能利用原始的二维影像资料作为输入画面即可产生立体视觉效果，而不需另外产生左右眼各自独立的视差影像资料。因此，本发明可大幅简化显示立体影像的驱动架构并有效降低制造成本。With the design of the present invention, not only does it not need to wear traditional shutter glasses, so the synchronization process of the switching timing of the shutter glasses and the timing of image signal transmission is unnecessary; on the other hand, the brightness control component can make the brightness of the individual visual fields of the left and right eyes different. This leads to the Pfelek effect, so that the original two-dimensional image data can be used as an input image to generate a stereoscopic visual effect without additionally generating independent parallax image data for the left and right eyes. Therefore, the present invention can greatly simplify the driving structure for displaying stereoscopic images and effectively reduce the manufacturing cost.

具体实施方式Detailed ways

图6为依本发明一实施例，显示一立体影像显示装置10的示意图。如图6所示，立体影像显示装置10包含一显示面板12、一第一液晶光阀(LCshutter)14、及一第二液晶光阀16。FIG. 6 is a schematic diagram showing a stereoscopicimage display device 10 according to an embodiment of the present invention. As shown in FIG. 6 , the stereoscopicimage display device 10 includes adisplay panel 12 , a first liquid crystal shutter (LC shutter) 14 , and a secondliquid crystal shutter 16 .

如图6所示，显示面板12包含多个红色(R)、绿色(G)或蓝色(B)子像素，各个子像素沿横向(X轴方向)及纵向(Y轴方向)排列形成多道横列及纵列。第一液晶光阀14设置于显示面板12的一侧，用以作为产生左右眼视觉分离效果的视差光件(parallax optic)。当液晶光阀14关闭时，光线可完全透过液晶光阀而为一平面二维(2D)影像显示模式；当液晶光阀14开启时，施加电压会改变液晶分子的配列状态形成多个不透光区块18，借由该不透光区块18产生的视差效果而形成一立体三维(3D)影像显示模式。图6中以投影虚线表示其中一不透光区块P于显示面板12上的投影位置，借以显示不透光区块18与各个子像素的相对位置。由图上可看出各个不透光区块1 8并非以沿Z轴方向完全叠合于一子像素上的方式配置，而是沿横向(X轴方向)偏移一定位移量，亦即不透光区块18的投影位置位于两相邻纵列子像素的交界上，如此交互间隔配置的不透光区块18及透光区块20与各个子像素错置后可产生左、右眼的视觉分离效果。As shown in FIG. 6 , thedisplay panel 12 includes a plurality of red (R), green (G) or blue (B) sub-pixels, and each sub-pixel is arranged in a horizontal direction (X-axis direction) and a vertical direction (Y-axis direction) to form multiple Rows and columns. The first liquid crystallight valve 14 is disposed on one side of thedisplay panel 12 and is used as a parallax optic to generate visual separation between left and right eyes. When the liquid crystallight valve 14 is closed, the light can completely pass through the liquid crystal light valve to form a flat two-dimensional (2D) image display mode; Thetransparent block 18 forms a stereoscopic three-dimensional (3D) image display mode through the parallax effect generated by theopaque block 18 . In FIG. 6 , the projection position of one of the opaque blocks P on thedisplay panel 12 is indicated by projecting dotted lines, so as to show the relative positions of theopaque block 18 and each sub-pixel. It can be seen from the figure that eachopaque block 18 is not arranged in such a way that it is completely superimposed on a sub-pixel along the Z-axis direction, but offset by a certain displacement along the lateral direction (X-axis direction), that is, not The projection position of the light-transmittingblock 18 is located at the junction of two adjacent columns of sub-pixels, so that the light-transmittingblock 18 and the light-transmittingblock 20 arranged alternately at intervals can produce left and right eyes after being staggered with each sub-pixel. Visual separation effect.

第二液晶光阀16是用以调整左右眼个别视域(viewing zones)的显示亮度。当液晶光阀16开启时，可利用施加电压控制其不同区域的光透过率，因此，如图6所示，液晶光阀16上可形成相对的一高透光区22及一低透光区24，而该高、低透光区22、24分布位置对应液晶光阀14上的透光区块20及不透光区块18，举例而言，由高透光区22及低透光区24于第一液晶光阀14上的投影区域22’及24’可看出，高透光区22及低透光区24分别位于不透光区块P的左方及右方。因此，借由第一液晶光阀14产生的视觉分离效果，观察者左眼及右眼具有相异的视域而可分别看到多个第一及第二像素单元，当液晶光阀16上形成相对的高透光区22及低透光区24后，观察者左眼及右眼透过第一液晶光阀14及第二液晶光阀16观看显示面板12时，受到高、低透光区的不同透光率影响，会使左、右眼所分别看到的多个第一及第二像素单元具有不同的亮度。此一左、右眼观看时的亮度差所引致的普菲立克效应，即可提供立体显示视觉效果。The second liquid crystallight valve 16 is used to adjust the display brightness of individual viewing zones of the left and right eyes. When the liquid crystallight valve 16 is opened, the light transmittance of its different regions can be controlled by applying a voltage. Therefore, as shown in FIG.area 24, and the distribution positions of the high and lowlight transmission areas 22 and 24 correspond to thelight transmission area 20 and theopaque area 18 on the liquid crystallight valve 14, for example, by the highlight transmission area 22 and the low light transmission area It can be seen from theprojection areas 22 ′ and 24 ′ of thearea 24 on the first liquid crystallight valve 14 that the highlight transmission area 22 and the lowlight transmission area 24 are located on the left and right of the opaque block P, respectively. Therefore, due to the visual separation effect produced by the first liquid crystallight valve 14, the observer's left eye and right eye have different visual fields and can respectively see a plurality of first and second pixel units. After the relative highlight transmission area 22 and lowlight transmission area 24 are formed, when the observer's left eye and right eye watch thedisplay panel 12 through the first liquid crystallight valve 14 and the second liquid crystallight valve 16, they will receive high and low light transmission. Influenced by different transmittances of the regions, the plurality of first and second pixel units seen by the left and right eyes respectively have different luminances. The Pfeiffer effect caused by the brightness difference between the left and right eyes can provide a stereoscopic display visual effect.

图7A为一示意简图，显示当显示面板12、第一液晶光阀14、第二液晶光阀16叠合后各个具不同透光率区域的相对分布。图7B显示观察者透过第一及第二液晶光阀观看显示面板12时，其左眼及右眼所分别看到的影像，其中每三个原色子像素(例如子像素R11、G11、B11)构成一显示点。如图7A所示，因第一液晶光阀14的各个不透光区块18均分布于两相邻子像素间，且每个不透光区块18的左方均为高透光区22而右方均为低透光区24，故观察者左眼看到如图7B左侧所示呈三角配列(delta topology)且亮度较暗的子像素R11、B11、G12、G21、R22、B22、R31、B31、G32，而右眼看到如图7B右侧所示呈三角配列且为一般亮度的子像素G11、R12、B12、R21、B21、G22、G31、R32、B32。因此，当显示面板1 2接收持续变化的动态影像时，左、右眼观看时的亮度差所引致的普菲立克效应可提供立体显示视觉效果。FIG. 7A is a schematic diagram showing the relative distribution of regions with different light transmittances when thedisplay panel 12 , the first liquid crystallight valve 14 , and the second liquid crystallight valve 16 are laminated. 7B shows the images seen by the left eye and the right eye of the observer when viewing thedisplay panel 12 through the first and second liquid crystal light valves, in which every three primary color sub-pixels (such as sub-pixels R11, G11, B11 ) constitute a display point. As shown in FIG. 7A , since eachopaque block 18 of the first liquid crystallight valve 14 is distributed between two adjacent sub-pixels, and the left side of eachopaque block 18 is a highlight transmittance area 22 The right side is the lowlight transmission area 24, so the left eye of the observer sees the sub-pixels R11, B11, G12, G21, R22, B22, R31, B31, G32, and the right eye sees sub-pixels G11, R12, B12, R21, B21, G22, G31, R32, B32 arranged in a triangle as shown in the right side of FIG. 7B and having normal brightness. Therefore, when thedisplay panel 12 receives continuously changing dynamic images, the Pfelix effect caused by the brightness difference between the left and right eyes can provide a stereoscopic display effect.

因此，借由本发明的设计，一方面不需穿戴传统的快门眼镜(shutterglasses)因而不需进行快门眼镜切换时序与影像信号传送时序的同步化过程；另一方面，作为亮度控制组件的第二液晶光阀16，可使左右眼个别视域的亮度产生差异而引致普菲立克效应，如此能利用原始的二维影像资料作为输入画面即可产生立体视觉效果，而不需另外产生左右眼各自独立的视差影像资料。因此，本发明可大幅简化显示立体影像的驱动架构并有效降低制造成本。Therefore, by means of the design of the present invention, on the one hand, there is no need to wear traditional shutter glasses (shutterglasses) so that the synchronization process of shutter glasses switching timing and image signal transmission timing is not required; on the other hand, the second liquid crystal as a brightness control component Thelight valve 16 can cause differences in the brightness of the individual visual fields of the left and right eyes to cause the Pflick effect. In this way, the original two-dimensional image data can be used as the input picture to produce a stereoscopic visual effect, without the need to generate separate images for the left and right eyes. Standalone parallax image data. Therefore, the present invention can greatly simplify the driving structure for displaying stereoscopic images and effectively reduce the manufacturing cost.

于上述实施例中，是以第一液晶光阀14的各个不透光区块1 8及透光区块20对应各个子像素错置形成一西洋棋盘式(checkerboard)分布，且观察者的左、右眼分别看到三角配列的子像素布局为例，说明本发明如何同时利用一视差光件(液晶光阀14)及一亮度控制组件(液晶光阀16)来达到立体显示效果，因于三角配列布局中，红色(R)子像素及绿色(G)子像素可同时交错出现在每一个水平及垂直配列上而可搭配子像素成色技术(sub-pixel rendering)来进一步提高分辨率及影像品质的目的。然而，搭配本发明设计的像素布局完全不限定，举例而言，亦可如图8A所示运用于条纹配列(stripe topology)的子像素布局，亦即不透光区块18对应整道子像素纵列形成为多道暗条纹，且每道暗条纹的左方为一道高透光区22而右方为一道低透光区24，如此观察者左眼看到图8B左侧所示亮度较暗的子像素纵列M1、N1、O1，右眼则看到图8B右侧所示一般亮度的子像素纵列M2、N2、O2，同样可产生立体显示视觉效果。In the above-mentioned embodiment, eachopaque block 18 and light-transmittingblock 20 of the first liquid crystallight valve 14 are misplaced corresponding to each sub-pixel to form a checkerboard distribution, and the observer's left Taking the sub-pixel layout of the triangular arrangement seen by the right eye and the right eye respectively as an example, it is explained how the present invention utilizes a parallax light element (liquid crystal light valve 14) and a brightness control component (liquid crystal light valve 16) to achieve a stereoscopic display effect at the same time. In the triangular arrangement layout, red (R) sub-pixels and green (G) sub-pixels can be interlaced in each horizontal and vertical arrangement at the same time, and sub-pixel rendering technology can be used to further improve the resolution and image purpose of quality. However, the pixel layout designed with the present invention is not limited at all. For example, it can also be applied to the sub-pixel layout of the stripe topology as shown in FIG. The rows are formed into multiple dark stripes, and the left side of each dark stripe is a highlight transmission area 22 and the right side is a lowlight transmission area 24, so that the left eye of the observer sees the darker light shown on the left side of Figure 8B The sub-pixel column M1, N1, O1, the right eye sees the sub-pixel column M2, N2, O2 of normal brightness shown on the right side of FIG. 8B, which can also produce a stereoscopic display visual effect.
