一种立体显示装置与立体投影显示系统A stereoscopic display device and a stereoscopic projection display system

技术领域technical field

本申请涉及显示技术领域，具体涉及一种立体显示装置与立体投影显示系统。The present application relates to the field of display technology, and in particular, to a stereoscopic display device and a stereoscopic projection display system.

背景技术Background technique

立体投影显示由于具有更好的沉浸感和显示效果，近年来已经得到了广泛的应用，如3D电影等；立体投影显示技术通常采用双眼视差的原理，使得观察者两只眼睛分别观察到具有视差的不同图像信息，以此产生立体视觉；常见的立体投影显示分为两种：时序式立体投影显示和偏振式立体投影显示，时序式立体投影显示需要投影仪具有高帧率，将对应于左、右眼的图像在时序上依次交叉投影显示在屏幕上；对于偏振式立体显示来说，如果采用单个投影仪实现偏振式的立体投影显示，则需要时序上交叉显示匹配不同偏振态的图像，使得左右眼在时序上依次观察到各自对应的图像信息，因此这种方法依然牺牲了帧率，要想实现高帧率立体显示，需要投影仪具有2倍的帧率。因此，现有的技术方案为单个投影仪实现高帧率显示带来了巨大挑战，尤其是以液晶显示面板作为空间光调制器，由于液晶显示面板相应频率的限制，导致很难实现高帧率。Stereoscopic projection display has been widely used in recent years due to its better immersion and display effect, such as 3D movies, etc. Stereoscopic projection display technology usually adopts the principle of binocular parallax, so that the observer's two eyes are observed with parallax respectively. There are two types of stereoscopic projection displays: sequential stereoscopic projection display and polarized stereoscopic projection display. Sequential stereoscopic projection display requires the projector to have a high frame rate, which will correspond to the left , The images of the right eye are cross-projected and displayed on the screen in sequence; for polarized stereoscopic display, if a single projector is used to realize polarized stereoscopic projection display, it is necessary to cross-display images matching different polarization states in time sequence. The left and right eyes can observe their corresponding image information in sequence, so this method still sacrifices the frame rate. To achieve high frame rate stereoscopic display, the projector needs to have twice the frame rate. Therefore, the existing technical solutions bring great challenges to the realization of high frame rate display by a single projector, especially when the liquid crystal display panel is used as the spatial light modulator, due to the limitation of the corresponding frequency of the liquid crystal display panel, it is difficult to achieve a high frame rate .

在一具体的实施例中，如图3所示，调制组件12为LCD，LCD包括：第一起偏片121、液晶盒122以及第一检偏片123。In a specific embodiment, as shown in FIG. 3 , the modulation component 12 is an LCD, and the LCD includes: a first polarizer 121 , a liquid crystal cell 122 and a first analyzer 123 .

第一起偏片121设置于转换光束的光路上，其用于将入射的转换光束变成偏振光束；具体地，第一起偏片121可以采用正面偏振状态相同的偏振片，即第一起偏片121具有第一偏振方向，可以将第一起偏片121设置成与二维微透镜阵列匹配的二维单元结构，或者也可以不将其设置为二维单元结构，而只是一体化结构，只要能够对入射的光束的偏振态进行起偏即可。The first polarizer 121 is disposed on the optical path of the converted light beam, and is used to convert the incident converted light beam into a polarized light beam; specifically, the first polarizer 121 can be a polarizer with the same front polarization state, that is, the first polarizer 121 With the first polarization direction, the first polarizer 121 can be set as a two-dimensional unit structure matching with the two-dimensional microlens array, or it can also not be set as a two-dimensional unit structure, but only an integrated structure, as long as it can The polarization state of the incident light beam may be polarized.

液晶盒122设置于偏振光束的光路上，其用于对偏振光束进行调制，输出调制光束；具体地，液晶盒122包括像素单元20，通过对每个像素单元20中的子像素的驱动电压进行调控，可以实现对子像素的调控。The liquid crystal cell 122 is arranged on the optical path of the polarized light beam, which is used to modulate the polarized light beam and output the modulated light beam; The regulation can realize the regulation of the sub-pixels.

The light beams of different polarization directions emitted by the unit 20 are matched; preferably, the first analyzer 121 is a two-dimensional unit structure, the analyzer unit corresponds to the pixel unit 20 one-to-one, and the first analyzer unit and the first sub-pixel unit 21 Correspondingly, the second analyzer unit and the second sub-pixel unit 22, so that each analyzer unit is matched with sub-pixels in different spatial positions to ensure that light beams of the same color can be converted into light beams of two polarization states.

对于使用LCD来作为调制组件12的应用场景来说，由于采用了二维微透镜阵列作为面角转换组件11，一方面通过二维微透镜阵列对光束的调控作用，提高了LCD中不透光结构(比如：黑矩阵或薄膜晶体管电路)所导致的光效损失，提高了LCD的最大输出亮度；另一方面利用二维微透镜阵列本身就可以实现彩色的像素分离，光源光束能通过微透镜111实现空间位置上的分离，从而能够避开LCD中的薄膜晶体管导线，提高了光束通过LCD时的效率，无需利用彩色滤光膜来进行像素分离，避免了彩色滤光膜带来的光效损失，使得光效利用率提高，同时也降低了LCD的热负载，提高了显示效果和可靠性。For the application scenario of using LCD as the modulation component 12, since the two-dimensional microlens array is used as the surface angle conversion component 11, on the one hand, the control effect of the two-dimensional microlens array on the light beam improves the opacity in the LCD. The loss of light efficiency caused by the structure (such as: black matrix or thin film transistor circuit) increases the maximum output brightness of the LCD; on the other hand, the two-dimensional microlens array itself can achieve color pixel separation, and the light source beam can pass through the microlens. 111 realizes the separation of spatial positions, thus avoiding the thin film transistor wires in the LCD, improving the efficiency of the light beam passing through the LCD, without using a color filter film for pixel separation, avoiding the light effect brought by the color filter film The loss increases the utilization rate of light efficiency, reduces the heat load of the LCD, and improves the display effect and reliability.

在一具体的实施方式中，结合图4与图5，微透镜111的形状为六边形，第一子像素单元21包括三个第一子像素，第二子像素单元22包括三个第二子像素，即每个微透镜111与六个圆形的子像素组成的像素单元对应。In a specific embodiment, referring to FIG. 4 and FIG. 5 , the shape of the micro-lens 111 is a hexagon, the first sub-pixel unit 21 includes three first sub-pixels, and the second sub-pixel unit 22 includes three second sub-pixels. The sub-pixels, that is, each microlens 111 corresponds to a pixel unit composed of six circular sub-pixels.

当光束301R和光束302R以两个不同的角度照射到LCD时，微透镜111将入射角度不同的光束301R和光束302R分别会聚到第一子像素211R和第二子像素212R，实现不同角度的光源对子像素的选择性照明；1231a-1232a为偏振方向不同的检偏单元，它们能够使得同一颜色的光束在不同空间位置的偏振态不同，使得不同空间位置的不同偏振态的光束可以分别进入人的左眼和右眼，从而实现立体显示。When the light beam 301R and the light beam 302R are irradiated to the LCD at two different angles, the microlens 111 condenses the light beam 301R and the light beam 302R with different incident angles to the first sub-pixel 211R and the second sub-pixel 212R respectively, so as to realize light sources of different angles Selective illumination of sub-pixels; 1231a-1232a are analyzer units with different polarization directions, which can make the polarization states of the same color beam different in different spatial positions, so that the beams of different polarization states in different spatial positions can enter the human body respectively. the left eye and right eye of the device to achieve stereoscopic display.

Since the images displayed by these two groups of pixels have parallax, stereoscopic display can be realized.

在另一实施方式中，如图7所示，第一子像素213R设置在相邻的两个第二子像素223R以及223B之间，第一子像素213G设置在相邻的两个第二子像素223R以及223G之间，第一子像素单元213沿着圆周方向旋转预设角度(比如60°)后与第二子像素单元223重合，第一子像素213B设置在相邻的两个第二子像素223G以及223B之间，子像素的排列方式为两组子像素彼此穿插排列，其工作原理与图6类似，在此不再赘述。In another embodiment, as shown in FIG. 7 , the first sub-pixel 213R is disposed between two adjacent second sub-pixels 223R and 223B, and the first sub-pixel 213G is disposed between two adjacent second sub-pixels Between the pixels 223R and 223G, the first sub-pixel unit 213 is rotated along the circumferential direction by a preset angle (for example, 60°) and then overlaps with the second sub-pixel unit 223, and the first sub-pixel 213B is arranged in two adjacent second Between the sub-pixels 223G and 223B, the arrangement of the sub-pixels is that two groups of sub-pixels are interspersed with each other, and the working principle is similar to that in FIG.

本实施例提供了一种高帧率立体显示的方案，采用匹配了二维微透镜阵列的调制组件，每个微透镜覆盖了至少六个子像素；角空间上分离的光源光束被输入至二维微透镜阵列进行面角转换，在通过微透镜后，角空间上分离的光束在面空间上分离，从而使得同一颜色的光源光束从不同的角度照射到调制组件上，能够通过微透镜将光束会聚到相应的子像素上，每组子像素通过空间积分可以实现全彩显示；而且由于仅通过一个面角转换组件就实现了光源光束从角空间到面空间的转换，结构简单。此外，由于采用了二维微透镜阵列作为面角转换组件，一方面通过二维微透镜阵列对光束的调控作用，提高了LCD中不透光结构所导致的光效损失，提高了LCD的等效开口率，提高了最大输出亮度，另一方面利用二维微透镜阵列本身实现了彩色的像素分离，避免了使用彩色滤光膜带来的光效损失，使得光效利用率进一步提高，同时也降低了LCD的热负载，提高了显示效果和可靠性。另外，每个像素单元包含两组子像素单元，两组子像素单元对应的检偏片经过像素化设计，使得两组子像素单元出射的光束的偏振方向相互垂直，以分别显示两幅具有视差的图像信息；使用者在佩戴了偏振眼镜后，可以观察到立体显示信息；而且由于两种偏振状态的出射光束是同时显示的，因此不会牺牲刷新频率，采用响应速度不是很快的LCD也可以实现高帧率立体显示。This embodiment provides a high frame rate stereoscopic display solution, using a modulation component matched with a two-dimensional microlens array, each microlens covers at least six sub-pixels; the light source beams separated in angular space are input to the two-dimensional The microlens array performs surface angle conversion. After passing through the microlens, the beams separated in the angular space are separated in the surface space, so that the light source beams of the same color are irradiated on the modulation components from different angles, and the beams can be converged by the microlenses. To the corresponding sub-pixels, each group of sub-pixels can achieve full-color display through spatial integration; and because only one surface angle conversion component is used to realize the conversion of the light source beam from the angular space to the surface space, the structure is simple. In addition, due to the use of a two-dimensional microlens array as the surface angle conversion component, on the one hand, the control effect of the two-dimensional microlens array on the light beam improves the light efficiency loss caused by the opaque structure in the LCD, and improves the etc. of the LCD. The effective aperture ratio improves the maximum output brightness. On the other hand, the use of the two-dimensional microlens array itself realizes the color pixel separation, which avoids the loss of light efficiency caused by the use of color filters, and further improves the light efficiency utilization rate. The thermal load of the LCD is also reduced, and the display effect and reliability are improved. In addition, each pixel unit includes two groups of sub-pixel units, and the analyzers corresponding to the two groups of sub-pixel units are designed to be pixelated, so that the polarization directions of the light beams emitted by the two groups of sub-pixel units are perpendicular to each other, so as to display two images with parallax respectively. After wearing polarized glasses, the user can observe the stereoscopic display information; and because the outgoing beams of the two polarization states are displayed at the same time, the refresh frequency will not be sacrificed, and the use of LCD with a low response speed is also possible. High frame rate stereoscopic display can be achieved.
