The number of barriers in the horizontal direction in the barrier array is one less than the number of lens elements in the horizontal direction in the tapered pitch microlens array.
请参阅图1和2,图中示出了微图像阵列中某一行的图像元和与该行对应的渐变节距微透镜阵列的某一行透镜元,如图中所示,图像元的数目为5,并且沿水平方向对称分布,透镜元的数目也是5个,并且也沿水平方向对称分布。每个图像元对应一个透镜元,并且每个图像元的中心与所对应的透镜元对应,如图2所示,图像元的中心为O1,透镜元的中心为O2,O1和O2对应,即O1和O2的连线与水平方向垂直,图像元与该图像元所对应的透镜元正对。并且,图像元的中心O1为将图像元划分为第一子图像元和第二子图像元。Referring to Figures 1 and 2, the image elements of a row in the micro image array and a row of lens elements of the progressive pitch microlens array corresponding to the row are shown. As shown in the figure, the number of image elements is 5, and symmetrically distributed in the horizontal direction, the number of lens elements is also five, and is also symmetrically distributed in the horizontal direction. Each image element corresponds to one lens element, and the center of each image element corresponds to the corresponding lens element. As shown in FIG. 2, the center of the image element is O1, and the center of the lens element is O2, and O1 and O2 correspond, that is, The line connecting O1 and O2 is perpendicular to the horizontal direction, and the image element is directly opposite to the lens element corresponding to the image element. And, the center O1 of the image element is to divide the image element into a first sub-picture element and a second sub-picture element.
透镜元所在的区域所对应的视区的第一条视线穿过该透镜元的中心向显示屏延伸后,与该透镜元对应的图像元的边界相交,其中,该边界为该图像元的远离中心区域T的边界。而该透镜元所在的区域所对应的视区的第二条视线与该透镜元的边界的连线的延长线与该透镜元对应的图像元的中心相交。其中,该透镜元的边界为该透镜的靠近中心位置M的边界。After the first line of sight of the viewport corresponding to the region where the lens element is located extends through the center of the lens element toward the display screen, the boundary of the image element corresponding to the lens element intersects, wherein the boundary is the distance of the image element The boundary of the central area T. And an extension line connecting the second line of sight of the view area corresponding to the area where the lens element is located and the boundary of the lens element intersects the center of the picture element corresponding to the lens element. Wherein, the boundary of the lens element is the boundary of the lens near the center position M.
例如,图2中,自上而下的第二个图像元和第二个透镜元为例。穿过该透镜元的中心O2的虚线为上第一条视线,穿过该透镜元的边界J2的虚线为上述第二条视线,第一条视线向显示屏方向延伸后与该透镜元对应的图像元的边界J1相交,第二条视线向显示屏方向延伸后与该透镜元对应的图像元的中心O1相交。For example, in FIG. 2, the second image element and the second lens element from top to bottom are taken as an example. The dotted line passing through the center O2 of the lens element is the upper first line of sight, and the dotted line passing through the boundary J2 of the lens element is the second line of sight. The first line of sight extends in the direction of the display screen and corresponds to the lens element. The boundary J1 of the image element intersects, and the second line of sight extends in the direction of the display screen to intersect the center O1 of the image element corresponding to the lens element.
其中,显示屏的中心区域T设有一个图像元,且中心区域T的水平方向的宽度等于位于中心区域T的图像元的水平节距,其中,图像元的水平节距为图像元的水平方向上的宽度,也即行方向上的宽度,同理,图像元的垂直节距为列方向上的宽度。渐变节距微透镜阵列的中心位置M处有一个透镜元,且中心位置M的水平方向上的宽度等于中心位置M 处的透镜元的水平节距。其中,透镜元的水平节距为透镜元的水平方向上的宽度,也即行方向上的宽度,同理,透镜元的垂直节距为列方向上的宽度。Wherein, the central area T of the display screen is provided with an image element, and the horizontal direction width of the central area T is equal to the horizontal pitch of the image element located in the central area T, wherein the horizontal pitch of the image element is the horizontal direction of the image element The width above, that is, the width in the row direction, is the same, the vertical pitch of the image element is the width in the column direction. There is a lens element at the center position M of the gradient pitch microlens array, and the width in the horizontal direction of the center position M is equal to the center position M The horizontal pitch of the lens elements at the location. Wherein, the horizontal pitch of the lens element is the width in the horizontal direction of the lens element, that is, the width in the row direction. Similarly, the vertical pitch of the lens element is the width in the column direction.
由图中可以看出,以中心位置M处的透镜元为中心,左右两侧镜像对称了两对透镜元,即与中心位置M处的透镜元水平方向上相邻的两个透镜元的水平节距相同,该行透镜元最外侧的两个透镜元的水平节距也相同。同理,中心区域T出的图像元两侧的图像元也是对称分布的,并且,在第一区域Q1内分布有两个图像元,并对应有两个透镜元;在第二区域Q2内也分布有两个图像元,并对应有两个透镜元。并且,每个图像元的水平节距与该图像元对应的透镜元的水平节距相同,并且,所有图像元的水平节距,以中心区域T的图像元为中心,向行边界的水平方向上逐渐增大,所有透镜元的水平解决,以中心位置M的透镜元为中心,向行边界的水平方向上逐渐增大。As can be seen from the figure, with the lens element at the center position M as the center, the left and right sides are mirror-symmetrical with two pairs of lens elements, that is, the level of two lens elements adjacent to the lens element at the center position M in the horizontal direction. The pitch is the same, and the horizontal pitch of the two outermost lens elements of the row of lens elements is also the same. Similarly, the image elements on both sides of the image element in the central region T are also symmetrically distributed, and two image elements are distributed in the first region Q1, and corresponding to two lens elements; in the second region Q2 also There are two image elements distributed, and there are two lens elements. And, the horizontal pitch of each image element is the same as the horizontal pitch of the lens element corresponding to the image element, and the horizontal pitch of all image elements is centered on the image element of the central area T, and is horizontal to the line boundary. The upper portion is gradually increased, and the level of all the lens elements is solved, centering on the lens element at the center position M, and gradually increasing in the horizontal direction of the line boundary.
障壁阵列3的障壁其一端设置在微图像阵列4中位于同一行的两个相邻图像元5的交界处,其另一端设置在与该两个图像元5相对应的两个相邻透镜元的交界处。The barrier ribs of the barrier array 3 are disposed at one end of the two adjacent image elements 5 of the same row in the micro image array 4, and at the other end of the two adjacent lens elements corresponding to the two image elements 5. Junction.
如图2所示,所述微图像阵列中的每一行的相邻图像元之间的连接处为第一连接点k1,所述渐变节距微透镜阵列中每一行的相邻两个透镜元之间的连接处为第二连接点k2,每个所述第一连接点k1对应一个所述第二连接点k2,相互对应的所述第一连接点k1和所述第二连接点k2之间设置一个所述障壁3。优选地,障壁3为板状结构,障壁3的一端与第一连接点k1连接,障壁3的另一端与该第一连接点k1对应的第二连接点k2连接。As shown in FIG. 2, the connection between adjacent image elements of each row in the micro image array is a first connection point k1, and the adjacent two lens elements of each row in the gradation pitch microlens array are The connection between the two is a second connection point k2, and each of the first connection points k1 corresponds to one of the second connection points k2, and the first connection point k1 and the second connection point k2 corresponding to each other One of the barriers 3 is provided between. Preferably, the barrier 3 is a plate-like structure, one end of the barrier 3 is connected to the first connection point k1, and the other end of the barrier 3 is connected to the second connection point k2 corresponding to the first connection point k1.
障壁对第一视区和第二视区起到遮挡作用,使得用户通过第一视区或第二视区观察显示屏时,尽量只看到第一子图像元或第二子图像元。例如,如图2中所示,白色区域为第一子图像元,灰色部分为第二子图像元,第一视区的用户观察图2中最下方的图像元时,最下方的图像元中的第一子图像元发出的光线经过最下方的两个透镜元射入用户的眼中,被用户观察到,而最下方的图像元中的第二子图像元发出的光线被避障遮挡,而无法射入到用户眼中,因此,无法被用户观察到。同样的道理,第一区域Q1的内的第一子图像都能被第一视区内的用户观察到,而第一区域Q1的内的第二子图像都被避障遮挡,而无法被第一视区内的用户观察到。同理,第二视区Q2内的第一子图像和第二子图像,在第二视区内的用户也仅能观察到第二子图像区域。The barrier occludes the first view area and the second view area, so that when the user observes the display screen through the first view area or the second view area, only the first sub-picture element or the second sub-picture element is seen as far as possible. For example, as shown in FIG. 2, the white area is the first sub-picture element, and the gray part is the second sub-picture element. When the user of the first view area observes the lowermost picture element in FIG. 2, the lowermost picture element is The light emitted by the first sub-picture element is incident on the user's eye through the two lowermost lens elements, and is observed by the user, and the light emitted by the second sub-picture element in the lowermost picture element is blocked by the obstacle avoidance. Can't be injected into the user's eyes, so it can't be observed by the user. By the same token, the first sub-image in the first region Q1 can be observed by the user in the first viewing zone, and the second sub-image in the first region Q1 is blocked by the obstacle avoidance, and cannot be The user in the first viewing area observed. Similarly, the first sub-image and the second sub-image in the second viewing zone Q2, the user in the second viewing zone can only observe the second sub-image area.
因此,第一视区和第二视区所观察的子图像元不同,例如,第一视区仅能观察到第一子图像元,第二子图像元仅能观察到第二子图像元,第一视区和第二视区内能够看到两个不同的3D场景。Therefore, the sub-picture elements observed by the first view area and the second view area are different. For example, the first sub-picture element can only observe the first sub-picture element, and the second sub-picture element can only observe the second sub-picture element. Two different 3D scenes can be seen in the first viewport and the second viewport.
