技术领域Technical field
本发明涉及半导体技术领域,尤其涉及一种三维显示器件。The present invention relates to the field of semiconductor technologies, and in particular, to a three-dimensional display device.
背景技术Background technique
3D(3-Dimensional,三维)立体显示,尤其是裸眼3D已成为显示领域的发展趋势。3D显示是基于双眼立体视觉原理来实现立体效果。即人的两只眼睛看到的不同图像在大脑中合成后,可呈现出当前看到的物体的三维形态。目前,实现裸眼3D显示的技术大多通过设置光屏障或光栅等遮蔽物,在显示屏前安装视差屏障来控制或遮挡光线的方向,从而让左右眼接收不同的图像,产生立体效果。3D (3-Dimensional, three-dimensional) stereoscopic display, especially the naked eye 3D has become a development trend in the display field. The 3D display is based on the principle of binocular stereo vision to achieve a stereoscopic effect. That is, after the different images seen by the two eyes of the human body are synthesized in the brain, the three-dimensional shape of the currently seen object can be presented. At present, the technology for realizing the naked-eye 3D display mostly uses a barrier such as a light barrier or a grating, and a parallax barrier is installed in front of the display screen to control or block the direction of the light, so that the left and right eyes receive different images and generate a stereoscopic effect.
如图1所示,在成像像素前设置遮挡式光栅,通过遮挡式光栅使得进入左右眼的图像不同(进入左眼图像用白色标示,进入右眼的图像用黑色标示)。在立体显示模式下,应该由左眼看到的图像显示在液晶屏上时,不透明的条纹会遮挡右眼;同理,应该由右眼看到的图像显示在液晶屏上时,不透明的条纹会遮挡左眼,通过将左眼和右眼的可视画面分开,使观者看到3D影像。但同时由于遮挡式光栅的阻挡,使得3D显示图像的亮度变低。 As shown in FIG. 1, an occlusion grating is disposed in front of the imaging pixel, and the images entering the left and right eyes are different by the occlusion grating (the image entering the left eye is marked in white, and the image entering the right eye is marked in black). In the stereo display mode, when the image that should be seen by the left eye is displayed on the LCD screen, the opaque stripes will block the right eye; similarly, when the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block. The left eye allows the viewer to see the 3D image by separating the visible images of the left and right eyes. However, at the same time, the brightness of the 3D display image becomes low due to the blocking of the occlusion grating.

优选地,图形反射层的反射区域308和透过区域309重复排列。所述重复排列是指:图形反射层的反射区域和透过区域所呈现的图形呈有规律性排列,排列方式可以包括:横向以条状排列、纵向以条状排列,或者在横向与纵向同时以孔状排列。其中,重复的距离为左眼或右眼在相邻的奇数列或偶数列在图形反射层的投影的重复距离;或者,反射区域与透过区域重复排列的重复距离为:右眼视点在相邻的奇数列子像素在所述图形反射层的投影的重复距离,或者左眼视点在相邻的偶数列子像素在所述图形反射层的投影的重复距离。Preferably, the reflective region 308 and the transmissive region 309 of the patterned reflective layer are repeatedly arranged. The repeating arrangement means that the reflection area and the transmission area of the graphic reflection layer are regularly arranged, and the arrangement may include: horizontally arranged in strips, longitudinally arranged in strips, or in horizontal and vertical directions. Arranged in a hole shape.

以矩形的穿透式显示屏为例,图5示出了一种反射区域和透过区域纵向以条状排列的示意图,图6示出了一种反射区域和透过区域横向以条状排列的示意图,图7示出了一种反射区域和透过区域在横向与纵向同时以孔状排列的示意图。Taking a rectangular transmissive display screen as an example, FIG. 5 shows a schematic view in which a reflective region and a transmissive region are longitudinally arranged in a strip shape, and FIG. 6 shows a reflective region and a transmissive region laterally arranged in stripes. Schematic diagram, FIG. 7 shows a schematic view in which a reflective region and a transmissive region are arranged in a hole shape at the same time in the lateral direction and the longitudinal direction.
如图5所示,图中灰度填充的显示区域为反射区域,白色填充区域为透过区域。反射区域和透过区域分别由多个与像素阵列的列所平行的条状区域组成,且呈间隔排列。每个条状的反射区域(即图中的一条灰度填充的区域)所在的位置,与像素阵列中的相邻两列像素对应。As shown in FIG. 5, the display area of the grayscale fill in the figure is a reflection area, and the white fill area is a transmission area. The reflective area and the transmissive area are respectively composed of a plurality of strip-shaped regions parallel to the columns of the pixel array, and are arranged at intervals. The position of each strip-shaped reflective area (ie, a gray-filled area in the figure) corresponds to two adjacent columns of pixels in the pixel array.
如图6所示,图中灰度填充的显示区域为反射区域,白色填充区域为透过区域。反射区域和透过区域分别由多个与像素阵列的行所平行的条状区域组成,且呈间隔排列。每个条状的反射区域(即图中的一条灰度填充的区域)所在的位置,与像素阵列中的相邻两行像素对应。 As shown in FIG. 6, the display area of the grayscale fill in the figure is a reflection area, and the white fill area is a transmission area. The reflective area and the transmissive area are respectively composed of a plurality of strip-shaped regions parallel to the rows of the pixel array, and are arranged at intervals. The position of each strip-shaped reflective area (ie, a gray-filled area in the figure) is located corresponding to two adjacent rows of pixels in the pixel array.
如图7所示,图中灰度填充的显示区域为反射区域,白色填充区域为透过区域。反射区域由多个孔状的小区域(如图中的一个灰度填充的区域)组成,所述多个孔状的小区域呈交错排列。比如,对应于像素阵列的第i行(1<i<M,M为像素阵列的行数),其孔状的小区域的分布分别与第i-1行和第i+1行的孔状小区域的分布相交错,并且,对应于像素阵列的第j列(1<j<N,N为像素阵列的列数),其孔状的小区域的分布分别与第j-1列和第j+1列的孔状小区域的分布相交错。As shown in FIG. 7, the display area of the grayscale fill in the figure is a reflection area, and the white fill area is a transmission area. The reflective area is composed of a plurality of small aperture-shaped regions (a region filled with a gray scale as shown in the figure), and the plurality of small aperture-like regions are staggered. For example, corresponding to the ith row of the pixel array (1<i<M, M is the number of rows of the pixel array), the distribution of the small area of the hole shape is the hole shape of the i-1th row and the i+1th row, respectively. The distribution of the small regions is staggered, and corresponds to the jth column of the pixel array (1<j<N, N is the number of columns of the pixel array), and the distribution of the small regions of the holes is respectively associated with the j-1th column and the The distribution of small pore-like regions in the j+1 column is staggered.
例如,在反射区域和透过区域在横向与纵向同时以孔状排列的情况下,如果像素阵列中子像素的排列如图8所示,其中,R表示红色,G表示绿色,B表示蓝色,W表示白色,图中的虚线框表示图形反射层的透射区域的位置。如果沿图8中剖线a进行剖切,从其剖面可以看出其透过区域与子像素的位置关系与图2类似,同样的,如果沿图8中剖线b进行剖切,从其剖面可以看出其透过区域与子像素的位置关系也与图2类似,也就是说,从这两个方向均可感受到3D显示效果。For example, in the case where the reflective region and the transmissive region are arranged in a hole shape at the same time in the lateral direction and the longitudinal direction, if the arrangement of the sub-pixels in the pixel array is as shown in FIG. 8, where R represents red, G represents green, and B represents blue. W represents white, and the dotted line in the figure indicates the position of the transmission area of the pattern reflection layer. If it is cut along the line a in FIG. 8, it can be seen from the cross section that the positional relationship between the transmission region and the sub-pixel is similar to that of FIG. 2, and similarly, if it is cut along the line b in FIG. The cross-section can be seen that the positional relationship between the transmission region and the sub-pixel is similar to that of FIG. 2, that is, the 3D display effect can be felt from both directions.
需要说明的是,图5、图6和图7仅为示例,图5和图6中所示的条状排列的反射区域和透过区域,其宽度大小以及间隔距离并不限于图中所示的情况,图7中所示的孔状交错排列的反射区域和透过区域,其形状以及大小以及间隔距离并不限于图中所示的情况。It should be noted that FIG. 5, FIG. 6 and FIG. 7 are only examples, and the stripe-shaped reflective region and the transmissive region shown in FIG. 5 and FIG. 6 are not limited to the width and the separation distance. In the case of the hole-shaped staggered reflection region and transmission region shown in Fig. 7, the shape and size and the separation distance are not limited to those shown in the drawings.
当图形反射层的反射区域和透过区域条状排列时,人眼在平行条状的方向存在视点,因此可以看到三维显示效果。比如,当形反射层的反射区域和透过区域横向以条状排列时,人眼在横向方向可以看到三维显示效果,当形反射层的反射区域和透过区域纵向以条状排列时,人眼在纵向方向可以看到三维显示效果。当图形反射层的反射区域和透过区域在横向与纵向同时以孔状排列时,可通过调整显示的内容,使人眼在横向和纵向两个方向的不同视点都能看到三维显示效果。When the reflection area and the transmission area of the pattern reflection layer are arranged in a strip shape, the human eye has a viewpoint in a direction parallel to the strip, so that a three-dimensional display effect can be seen. For example, when the reflective area and the transmissive area of the reflective layer are arranged in a strip shape in the lateral direction, the human eye can see a three-dimensional display effect in the lateral direction, and when the reflective area of the reflective layer and the longitudinal direction of the transmissive area are arranged in a strip shape, The human eye can see the three-dimensional display effect in the longitudinal direction. When the reflective area and the transmissive area of the pattern reflective layer are arranged in a hole shape at the same time in the horizontal direction and the longitudinal direction, the three-dimensional display effect can be seen by the human eye in different viewing directions in both the horizontal direction and the vertical direction by adjusting the displayed content.
