Description
本發明是有關於一種立體顯示裝置。The present invention relates to a stereoscopic display device.
因為左眼和右眼位置不同，所以各自觀察到的景象也有細微的差異，這種差異是產生立體感的根本原因，3D立體顯示器便是利用了眼晴的視覺特性來產生立體感。Because the positions of the left eye and the right eye are different, there are subtle differences in the observed scenes. This difference is the root cause of the stereoscopic effect. The 3D stereoscopic display utilizes the visual characteristics of the eye to create a three-dimensional effect.
傳統上達成立體感的方法為利用空間多工法，即在螢幕上的畫素分配多個視域(View)資訊，透過透鏡的分光效果在觀賞距離下會聚，產生多個視域(View)，觀察者對應於其中兩個視域，使兩眼對應到不同影像達成3D視覺效果。The traditional method of achieving stereoscopic effect is to use spatial multiplexing method, that is, to assign multiple view information to the pixels on the screen, and to converge at the viewing distance through the spectroscopic effect of the lens to generate multiple views. The observer corresponds to two of the fields of view, so that the two eyes correspond to different images to achieve a 3D visual effect.

The plurality of pixels 141 are arranged along the first direction D1 and the second direction D2 which are perpendicular to each other, and each of the pixels 141 includes a plurality of sub-pixels 141R, 141G, and 141B arranged along the first direction D1.
需要說明的是，一般的顯示裝置在使用時，其每一畫素的子畫素是在水平方向上排列的。而在使用本實施方式之立體顯示裝置100時，可調整立體顯示裝置100的擺設方位而使第一方向D1平行於鉛直方向，並使第二方向D2平行於水平方向。也就是說，在本實施方式的立體顯示裝置100中，每一畫素141的子畫素141R、141G、141B是在鉛直方向上排列的。It should be noted that when a general display device is used, the sub-pixels of each pixel are arranged in the horizontal direction. On the other hand, when the stereoscopic display device 100 of the present embodiment is used, the orientation of the stereoscopic display device 100 can be adjusted such that the first direction D1 is parallel to the vertical direction and the second direction D2 is parallel to the horizontal direction. That is, in the stereoscopic display device 100 of the present embodiment, the sub-pixels 141R, 141G, and 141B of each pixel 141 are arranged in the vertical direction.
第二柱狀透鏡陣列150設置於導光板130的出光面132與顯示模組140之間，並配置以將經反射之指向性光線(即離開出光面132之指向性光線)聚焦於顯示模組140上的複數個長條區域142。每一長條區域142係平行於第一方向D1。顯示模組140配置以將經聚焦之指向性光線轉換為複數組畫素光線。換言之，第二柱狀透鏡陣列150於第二方向D2上具有光學能力，以使經反射之指向性光線聚焦至沿第二方向D2排列之長條區域142。為了達到將經反射之指向性光線聚焦於長條區域142之目的，本實施方式係使顯示模組140位於第二柱狀透鏡陣列150的焦面上，且第二柱狀透鏡陣列150具有複數個第二柱狀透鏡151，複數個第二柱狀透鏡151相對第一方向D1為平行設置。The second lenticular lens array 150 is disposed between the light-emitting surface 132 of the light guide plate 130 and the display module 140, and is configured to focus the reflected directional light (ie, the directional light leaving the light-emitting surface 132) on the display module. A plurality of strip regions 142 on 140. Each strip region 142 is parallel to the first direction D1. Display module 140 is configured to convert the focused directional light into a complex array of pixel light. In other words, the second lenticular lens array 150 has an optical capability in the second direction D2 to focus the reflected directional light rays to the elongated regions 142 arranged in the second direction D2. In order to achieve the purpose of focusing the reflected directional light on the strip region 142, the present embodiment is such that the display module 140 is located on the focal plane of the second lenticular lens array 150, and the second lenticular lens array 150 has a plurality of The second lenticular lenses 151 and the plurality of second lenticular lenses 151 are disposed in parallel with respect to the first direction D1.
進一步來說，複數個畫素141沿著垂直於第一方向D1之第二方向D2排列成複數個畫素排(及第4圖所示之縱向排)。各長條區域142分別對應通過各畫素排。因此，每一畫素141的所有子畫素141R、141G、141B都會有部分之指向性光線通過。Further, the plurality of pixels 141 are arranged in a plurality of pixel rows (and the vertical rows shown in FIG. 4) along a second direction D2 perpendicular to the first direction D1. Each strip area 142 corresponds to each pixel row. Therefore, all of the sub-pixels 141R, 141G, and 141B of each pixel 141 have a part of the directional light passing therethrough.
第三柱狀透鏡陣列160設置於顯示模組140遠離導光板130的一側，並配置以將畫素光線分別導引至複數個視域。為了達到將畫素光線分別導引至複數個視域之目的，本實施方式係使顯示模組140位於第三柱狀透鏡陣列160的焦面上，且第三柱狀透鏡陣列160具有複數個第三柱狀透鏡161，複數個第三柱狀透鏡161相對於第一方向D1為傾斜設置，如第4圖所示。如前所述，若在每一畫素141的子畫素141R、141G、141B是在鉛直方向上排列的情況之下使用本實施方式之立體顯示裝置100，則第三柱狀透鏡陣列160可將畫素光線分別導引至水平方向上的複數個視域。The third lenticular lens array 160 is disposed on a side of the display module 140 away from the light guide plate 130, and is configured to guide the pixel light to a plurality of fields of view. In order to achieve the purpose of guiding the pixel light to a plurality of fields of view, the present embodiment is such that the display module 140 is located on the focal plane of the third lenticular lens array 160, and the third lenticular lens array 160 has a plurality of The third lenticular lens 161 has a plurality of third lenticular lenses 161 which are inclined with respect to the first direction D1 as shown in FIG. As described above, if the stereoscopic display device 100 of the present embodiment is used in the case where the sub-pixels 141R, 141G, and 141B of each pixel 141 are arranged in the vertical direction, the third lenticular lens array 160 can be used. The pixel light is separately directed to a plurality of fields of view in the horizontal direction.
於一些實施方式中，第三柱狀透鏡161相對第一方向D1具有傾斜角θ。傾斜角θ實質上滿足： θ = tan-1 (1/N) 其中N為大於1之自然數。In some embodiments, the third lenticular lens 161 has an oblique angle θ with respect to the first direction D1. The tilt angle θ substantially satisfies: θ = tan -1 (1/N) where N is a natural number greater than one.
於一些實施方式中，上述之N可以是2、3、4、5、6、7或8，但本發明並不以此為限。In some embodiments, the above N may be 2, 3, 4, 5, 6, 7, or 8, but the invention is not limited thereto.
舉例來說，請參照第2A圖與第4圖，於本實施方式中，為了製作出可提供五視域的立體顯示裝置100，可設計使第一柱狀透鏡陣列120的每一第一柱狀子透鏡121在第一方向D1上對應五個光源112(見第2A圖)。因此，每一第一柱狀子透鏡121可將五個光源112的光轉換成五個指向性光線。For example, referring to FIG. 2A and FIG. 4 , in the present embodiment, in order to create a stereoscopic display device 100 that can provide five viewing fields, each first column of the first lenticular lens array 120 can be designed. The sub-lens 121 corresponds to five light sources 112 in the first direction D1 (see FIG. 2A). Therefore, each of the first cylindrical sub-lenses 121 can convert the light of the five light sources 112 into five directional light rays.
進一步，可設計使每一長條區域142在第二方向D2上的寬度小於等於每一畫素141在第二方向D2上的寬度。舉例來說，如第4圖所示，可設計使每一長條區域142與子畫素141R重合的區域在第二方向D2上的寬度佔據每一畫素141在第二方向D2上的寬度的1/6倍，而每一長條區域142與子畫素141R重合的區域在第一方向D1上的寬度佔據每一畫素141在第一方向D1上的寬度的1/3(因每一畫素被三等分)。因此，在本實施方式中，第三柱狀透鏡161相對第一方向D1所具有傾斜角θ即可藉由每一長條區域142與子畫素141R重合的區域在第一方向D1與第二方向D2上的寬度計算而獲得。具體來說，依據上述θ = tan-1 (1/N)之公式，其中，N=(1/3)÷(1/6)，故本實施方式所計算出之傾斜角θ = tan-1 (1/2)。故換句話說，每一長條區域142在第二方向D2上的寬度係等於每一畫素141在第二方向D2上的寬度的1/(3N)倍。Further, the width of each strip region 142 in the second direction D2 may be designed to be less than or equal to the width of each pixel 141 in the second direction D2. For example, as shown in FIG. 4, the width of the region in which the each of the elongated regions 142 and the sub-pixels 141R coincide in the second direction D2 can be designed to occupy the width of each of the pixels 141 in the second direction D2. 1/6 times, and the width of the region where each of the strip regions 142 coincides with the subpixel 141R in the first direction D1 occupies 1/3 of the width of each pixel 141 in the first direction D1 (because each A pixel is divided into three equal parts). Therefore, in the present embodiment, the third lenticular lens 161 has an inclination angle θ with respect to the first direction D1, and the region where each of the elongated regions 142 coincides with the sub-pixel 141R is in the first direction D1 and the second. Obtained from the width calculation in direction D2. Specifically, according to the above formula of θ = tan -1 (1/N), where N = (1/3) ÷ (1/6), the tilt angle θ = tan -1 calculated in the present embodiment (1/2).

請參照第8圖，其為繪示本發明另一實施方式之顯示模組140與第三柱狀透鏡陣列160的部分平面示意圖。於本實施方式中，為了製作出可提供十視域的立體顯示裝置100，可設計使第一柱狀透鏡陣列120的每一第一柱狀子透鏡121在第一方向D1上對應十個光源112。因此，每一第一柱狀子透鏡121可將十個光源112的光轉換成十個指向性光線。Please refer to FIG. 8 , which is a partial plan view showing a display module 140 and a third lenticular lens array 160 according to another embodiment of the present invention.

Obtained from the width calculation in direction D2. Specifically, according to the above formula of θ = tan -1 (1/N), where N = (1/3) ÷ (1/12), the tilt angle θ = tan -1 calculated in the present embodiment (1/4).
需要說明的是，在第三柱狀子透鏡的排列方向上，每一第三柱狀子透鏡可對應地虛擬分為十個部分，且此十部分可將顯示模組140所轉換而來的畫素光線分別導引至十個視域，而相鄰之第三柱狀子透鏡再重複此十個視域。It should be noted that, in the direction in which the third columnar sub-lens is arranged, each of the third columnar sub-lenses can be correspondingly virtually divided into ten parts, and the ten parts can convert the pixels converted by the display module 140. The rays are directed to ten fields of view, respectively, and the adjacent third columnar sub-lens repeats the ten fields of view.
再進一步，可設計使每一第三柱狀透鏡161在第二方向D2上的寬度等於每一畫素141在第二方向D2上的寬度的10/12倍(見第8圖)。在此述結構配置之下，由第8圖來看，位於最左上方之畫素141的子畫素141R的畫素光線可被第三柱狀透鏡161導引至第一視域(圖中標示1)，而右方相鄰之畫素141與下方相鄰之畫素141中的子畫素141R的畫素光線可被第三柱狀透鏡161分別導引至第三視域(圖中標示3)與第四視域(圖中標示4)。第8圖中的其他6個畫素141中的子畫素141R的畫素光線所對應之視域在此不再贅述，可直接參看第8圖的標示。Still further, the width of each of the third lenticular lenses 161 in the second direction D2 may be designed to be equal to 10/12 times the width of each of the pixels 141 in the second direction D2 (see Fig. 8). Under the structural configuration described herein, as seen from FIG. 8, the pixel ray of the sub-pixel 141R of the pixel 141 located at the uppermost left direction can be guided to the first field of view by the third lenticular lens 161 (in the figure) Marked 1), and the pixel ray of the neighboring pixel 141 and the sub-pixel 141R in the pixel 141 adjacent to the lower side can be respectively guided by the third lenticular lens 161 to the third field of view (marked 3 in the figure) ) and the fourth field of view (marked 4 in the figure).

請參照第9圖，其為繪示採用第8圖之光學配置之立體顯示裝置100中之一種子畫素所對應之視域圖。如第9圖所示，所有斜線的交點所在之畫素141中的一種子畫素(例如，第8圖所示之子畫素141R)的畫素光線皆對應至(被第三柱狀透鏡161導引至)第一視域。也就是說，位於第一視域的觀賞者可在所有斜線的交點所在之畫素141的位置觀看到此種子畫素的畫素光線。而位於其他九個視域的觀賞者依據同樣原理可分別在其他畫素141的位置觀看到此種子畫素的畫素光線，在此恕不贅述。Please refer to FIG. 9 , which is a view of a field corresponding to one of the seed pixels in the stereoscopic display device 100 of the optical configuration of FIG. 8 . As shown in FIG. 9, the pixel light of one of the sub-pixels (for example, the sub-pixel 141R shown in FIG. 8) of the pixel 141 where the intersection of all the oblique lines is located corresponds to (by the third cylindrical lens 161). Guided to the first field of view. That is to say, the viewer in the first viewing zone can view the pixel light of the seed pixel at the position of the pixel 141 where the intersection of all the diagonal lines is located. The viewers in the other nine fields of view can view the pixel light of the seed pixel at the position of the other pixels 141 according to the same principle, and will not be described here.
然而，對於採用第4圖之光學配置之立體顯示裝置100來說，每一視域的解析度會降為1/5倍。為了解決此問題，請參照第10圖，其為繪示本發明一實施方式之第一柱狀透鏡陣列120與移動模組170的正視圖。如第1圖至第2B圖與第10圖所示，於本實施方式中，每一第一柱狀子透鏡121在第二方向D2上具有第一節距P1。第一柱狀透鏡陣列120還具有複數個第二柱狀子透鏡122。第二柱狀子透鏡122沿著第二方向D2排列，並與第一方向D1垂直設置。每一第二柱狀子透鏡122在第二方向D2上具有第二節距P2，且第一節距P1為第二節距P2的5倍。也就是說，當第二柱狀子透鏡122光學耦合於光源112與入光面131之間時，每一第二柱狀子透鏡122可對應一個光源112，且經過第二柱狀子透鏡122的光線皆為正向光線，這將造成光線後續不會被導引至複數個視域，因此可使立體顯示裝置100恢復為原本的解析度。However, for the stereoscopic display device 100 using the optical configuration of FIG. 4, the resolution per field of view is reduced by a factor of one-fifth. In order to solve this problem, please refer to FIG. 10, which is a front view showing the first lenticular lens array 120 and the moving module 170 according to an embodiment of the present invention.

The first lenticular lens array 120 also has a plurality of second columnar sub-lenses 122. The second columnar sub-lenses 122 are arranged along the second direction D2 and are disposed perpendicular to the first direction D1. Each of the second columnar sub-lenses 122 has a second pitch P2 in the second direction D2, and the first pitch P1 is five times the second pitch P2. That is, when the second cylindrical sub-lens 122 is optically coupled between the light source 112 and the light incident surface 131, each of the second cylindrical sub-lenses 122 may correspond to one light source 112, and the light passing through the second cylindrical sub-lens 122 For forward ray, this will cause the ray to be subsequently not directed to a plurality of fields of view, thus allowing the stereoscopic display device 100 to return to its original resolution.
立體顯示裝置100還包含移動模組170，配置以移動第一柱狀透鏡陣列120，致使第一柱狀子透鏡121與第二柱狀子透鏡122中之一群選擇性地光學耦合於光源112與入光面131之間。藉此，立體顯示裝置100可藉由移動模組170而移動第一柱狀透鏡陣列120，致使第一柱狀子透鏡121光學耦合於光源112與入光面131之間，進而可供3D模式使用。可選地，立體顯示裝置100可藉由移動模組170而移動第一柱狀透鏡陣列120，致使第二柱狀子透鏡122光學耦合於光源112與入光面131之間，進而可供2D模式使用。The stereoscopic display device 100 further includes a moving module 170 configured to move the first lenticular lens array 120 such that one of the first cylindrical sub-lens 121 and the second cylindrical sub-lens 122 is selectively optically coupled to the light source 112 and the light entering the light. Between faces 131. Therefore, the stereoscopic display device 100 can move the first lenticular lens array 120 by moving the module 170, so that the first cylindrical sub-lens 121 is optically coupled between the light source 112 and the light incident surface 131, thereby being used in the 3D mode. . Optionally, the stereoscopic display device 100 can move the first lenticular lens array 120 by moving the module 170, so that the second cylindrical sub-lens 122 is optically coupled between the light source 112 and the light incident surface 131, thereby being available for 2D mode. use.
對於採用第6圖與第8圖之光學配置之立體顯示裝置100來說，每一視域的解析度分別會降為1/7倍與1/10倍。為了解決前述解析度下降的問題，依照前述相同原理，可將前述第二柱狀子透鏡122之第二節距P2分別修改為第一柱狀子透鏡121之第一節距P1的1/7倍與1/10倍。For the stereoscopic display device 100 using the optical configurations of FIGS. 6 and 8, the resolution of each field of view is reduced by 1/7 times and 1/10 times, respectively. In order to solve the problem of the aforementioned resolution reduction, according to the same principle as described above, the second pitch P2 of the second columnar sub-lens 122 can be modified to be 1/7 times of the first pitch P1 of the first columnar sub-lens 121, respectively. 1/10 times.
由以上對於本發明之具體實施方式之詳述，可以明顯地看出，在使用本發明的立體顯示裝置時，可調整立體顯示裝置的擺設方位而使每一畫素的子畫素在鉛直方向上排列。而在此擺設方位之下，本發明的立體顯示裝置可藉由第一柱狀透鏡陣列、第二柱狀透鏡陣列與第三柱狀透鏡陣列依據前述配置而達到將畫素光線分別導引至水平方向上的複數個視域的目的。除此之外，於本發明的立體顯示裝置中，第一柱狀透鏡陣列具有節距較大之第一柱狀子透鏡與節距較小之第二柱狀子透鏡。藉此，立體顯示裝置可選擇將第一柱狀子透鏡與光源光學耦合而供3D模式使用，或選擇將第二柱狀子透鏡與光源光學耦合而供2D模式使用，且此模式下可恢復解析度。From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that when the stereoscopic display device of the present invention is used, the orientation of the stereoscopic display device can be adjusted such that the sub-pixels of each pixel are in the vertical direction. Arranged on top. Under the orientation of the present invention, the stereoscopic display device of the present invention can guide the pixel light to the first lenticular lens array, the second lenticular lens array and the third lenticular lens array according to the foregoing configuration.
