一种液晶透镜模组及3D显示装置A liquid crystal lens module and 3D display device

技术领域technical field

本实用新型涉及3D显示技术领域，尤其涉及一种液晶透镜模组及3D显示装置。The utility model relates to the technical field of 3D display, in particular to a liquid crystal lens module and a 3D display device.

背景技术Background technique

在日常生活中人们是利用两只眼睛来观察周围具有空间立体感的外界景物的，三维（3D）显示技术就是利用双眼立体视觉原理使人获得三维空间感，其主要原理是使观看者的左眼与右眼分别接收到不同的影像，由观看者两眼之间的瞳距产生的位置差异，使存在“双眼视差”的两副图像构成一对“立体图象对”，而“立体图像对”在经由大脑分析融合后使观看者产生立体感。In daily life, people use two eyes to observe the external scene with a three-dimensional sense of space. Three-dimensional (3D) display technology uses the principle of binocular stereo vision to enable people to obtain a sense of three-dimensional space. The main principle is to make the viewer's left The eye and the right eye receive different images respectively, and the position difference caused by the interpupillary distance between the viewer's two eyes makes the two images with "binocular parallax" constitute a "stereoscopic image pair", while the "stereoscopic image "Right" makes the viewer feel three-dimensional after being analyzed and fused by the brain.

目前，3D显示技术有裸眼式和眼镜式两大类。所谓裸眼式就是通过在显示器上进行特殊的处理，把经过编码处理的3D视频影像独立送入人的左右眼，从而令用户无需借助立体眼镜即可裸眼体验立体感觉。Currently, there are two types of 3D display technologies: glasses-free and glasses-based. The so-called naked-eye type is to send the coded 3D video images to the left and right eyes independently through special processing on the display, so that users can experience the stereoscopic feeling without the help of stereoscopic glasses.

目前，实现裸眼3D显示的显示装置为在诸如液晶显示器（LCD）的光源阵列前方设置光屏障（Barrier）或透镜光栅等遮蔽物，如图1所示，通过透镜光栅可以将显示装置发出的光线汇聚在其焦点上的原理，使左眼像素发出的光射向观看者的左眼，右眼像素发出的光射向观看者的右眼，实现3D显示的效果。At present, a display device that realizes naked-eye 3D display is to set a light barrier (Barrier) or a lens grating in front of a light source array such as a liquid crystal display (LCD). As shown in Figure 1, the light emitted by the display device can The principle of converging on its focal point makes the light emitted by the left-eye pixel shoot to the viewer's left eye, and the light emitted by the right-eye pixel shoots to the viewer's right eye, realizing the effect of 3D display.

为了实现三维显示，现有技术中的一种方案是在显示屏上增加一层液晶透镜，如图2所示，液晶透镜一般是由上基板、下基板、以及在两个基板之间的液晶层组成的，上基板和下基板分别具有条状电极和面电极；在3D显示模式时，通过对不同位置的条状电极通入不同的电压，产生不同的电场强度，使对应的液晶分子发生不同程度的偏转，从而使液晶层产生透镜的效果。In order to realize three-dimensional display, one solution in the prior art is to add a layer of liquid crystal lens on the display screen. The upper substrate and the lower substrate have strip electrodes and surface electrodes respectively; in the 3D display mode, different voltages are applied to the strip electrodes at different positions to generate different electric field strengths, so that the corresponding liquid crystal molecules generate Different degrees of deflection, so that the liquid crystal layer produces the effect of a lens.

在图2所示的液晶光栅的结构中，当相邻的条状电极之间的具有较大的间隙，例如超过30μm，会造成位于相邻条状电极中间的液晶分子与其他区域的液晶分子取向不一致。并且，在相邻的条状电极之间在通入不同电压的信号时，会在两者之间产生水平电场，影响位于两者之间的液晶分子发生偏转，如图3所示，虚线所示为正常的液晶分子取向方向，由于V1和V2之间产生的水平电场，实线所示的液晶分子会发生微小的偏转。这些取向不一致的液晶分子会造成液晶透镜的串扰问题，即显示装置的右眼像素发出的光，会因液晶分子的不正常取向，射向观看者的左眼；显示装置的左眼像素发出的光，会因液晶分子的不正常取向，射向观看者的右眼，影响3D的显示效果。In the structure of the liquid crystal grating shown in Figure 2, when there is a large gap between adjacent strip electrodes, for example, more than 30 μm, the liquid crystal molecules in the middle of the adjacent strip electrodes will be separated from the liquid crystal molecules in other regions. Inconsistent orientation. Moreover, when signals of different voltages are passed between adjacent strip electrodes, a horizontal electric field will be generated between them, which will affect the deflection of the liquid crystal molecules located between them, as shown in Figure 3, indicated by the dotted line Shown as the normal alignment direction of liquid crystal molecules, due to the horizontal electric field generated between V1 and V2, the liquid crystal molecules shown by the solid line will be slightly deflected. These liquid crystal molecules with inconsistent orientation will cause the problem of crosstalk of the liquid crystal lens, that is, the light emitted by the right-eye pixel of the display device will be emitted to the left eye of the viewer due to the abnormal orientation of the liquid crystal molecules; the light emitted by the left-eye pixel of the display device Light, due to the abnormal orientation of the liquid crystal molecules, will be emitted to the right eye of the viewer, affecting the 3D display effect.

因此，如何降低液晶透镜3D显示的串扰问题，是本领域技术人员亟需解决的技术问题。Therefore, how to reduce the crosstalk problem of the liquid crystal lens 3D display is a technical problem urgently needed to be solved by those skilled in the art.

具体实施方式Detailed ways

下面结合附图，对本实用新型实施例提供的液晶透镜模组及3D显示装置的具体实施方式进行详细地说明。The specific implementation manners of the liquid crystal lens module and the 3D display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

附图中各层厚度和区域大小形状不反映液晶透镜模组的真实比例，目的只是示意说明本实用新型内容。The thickness of each layer and the size and shape of the area in the accompanying drawings do not reflect the real proportion of the liquid crystal lens module, and the purpose is only to illustrate the content of the utility model.

本实用新型实施例提供的液晶透镜模组，如图4所示，具体包括：液晶透镜1、位于液晶透镜1下表面的第一偏光片2，以及位于液晶透镜1上表面的第二偏光片3；The liquid crystal lens module provided by the embodiment of the present invention, as shown in Figure 4, specifically includes: aliquid crystal lens 1, afirst polarizer 2 positioned on the lower surface of theliquid crystal lens 1, and a second polarizer positioned on the upper surface of theliquid crystal lens 1 3;

第一偏光片2和第二偏光片3的光透过轴方向相互平行。The light transmission axis directions of thefirst polarizer 2 and thesecond polarizer 3 are parallel to each other.

本实用新型实施例提供上述液晶透镜模组，在液晶透镜的上下表面分别设置第一偏光片和第二偏光片，且第一偏光片和第二偏光片的光透过轴方向一致。由于液晶透镜内部的液晶分子取向不一致和水平方向扭曲等问题，透过第一偏光片的偏振光在经过液晶透镜的作用后，会造成一部分偏振光的偏振方向发生变化，而第二偏光片能过滤这部分偏振方向发生变化的偏振光，减少由这部分偏振方向发生变化的偏振光引起的液晶透镜3D显示的串扰问题。The embodiment of the present invention provides the above-mentioned liquid crystal lens module. The first polarizer and the second polarizer are respectively arranged on the upper and lower surfaces of the liquid crystal lens, and the directions of the light transmission axes of the first polarizer and the second polarizer are consistent. Due to problems such as inconsistent orientation of liquid crystal molecules inside the liquid crystal lens and distortion in the horizontal direction, after the polarized light passing through the first polarizer passes through the action of the liquid crystal lens, the polarization direction of a part of the polarized light will change, while the second polarizer can The part of the polarized light whose polarization direction changes is filtered to reduce the crosstalk problem of the liquid crystal lens 3D display caused by the part of the polarized light whose polarization direction changes.

在具体实施时，如图4所示，液晶透镜1一般设置有多个透镜单元4，在3D显示模式时，每个透镜单元4会对透过第一偏光片1的偏振光起透镜作用，将左眼像素发出的光射向观看者的左眼，右眼像素发出的光射向观看者的右眼，实现3D显示的效果。During specific implementation, as shown in FIG. 4 , theliquid crystal lens 1 is generally provided with a plurality oflens units 4, and in the 3D display mode, eachlens unit 4 acts as a lens for the polarized light passing through thefirst polarizer 1, The light emitted by the left-eye pixel is directed to the left eye of the viewer, and the light emitted by the right-eye pixel is directed to the right eye of the viewer to realize the effect of 3D display.

一般地，在显示器5中一个像素单元由三个亚像素组成，例如红、绿、蓝三个亚像素单元，在3D显示模式下，可以在奇数的亚像素列上显示左眼看到的画面，偶数的亚像素列上显示右眼看到的画面；当然也可以以n个亚像素列为一个周期，间隔显示左眼和右眼看到的画面，在此不做具体限定。Generally, a pixel unit in the display 5 is composed of three sub-pixels, such as three sub-pixel units of red, green, and blue. In the 3D display mode, the picture seen by the left eye can be displayed on the odd-numbered sub-pixel columns. Even-numbered sub-pixel rows display images viewed by the right eye; of course, n sub-pixel rows may be used as a period to display images viewed by the left eye and right eye at intervals, which is not specifically limited here.

在具体实施时，上述显示器5可以液晶（LCD）显示面板、有机电致发光（OLED）显示面板、等离子体（PDP）显示面板、或阴极射线（CRT）显示器等，在此不做限定。During specific implementation, the above-mentioned display 5 may be a liquid crystal (LCD) display panel, an organic electroluminescence (OLED) display panel, a plasma (PDP) display panel, or a cathode ray (CRT) display, etc., which are not limited herein.

并且，当3D显示装置应用于LCD显示面板时，由于LCD显示面板中具有偏光片，因此，在液晶透镜模组中可以省去位于液晶透镜下方的第一偏光片，将第二偏光片的光透过轴方向与LCD显示面板中的偏光片的光透过轴方向设置为一致。或者，直接省去LCD显示面板中的偏光片，在此不做限定。Moreover, when the 3D display device is applied to an LCD display panel, since the LCD display panel has a polarizer, the first polarizer located under the liquid crystal lens can be omitted in the liquid crystal lens module, and the light from the second polarizer The transmission axis direction is set to be consistent with the light transmission axis direction of the polarizer in the LCD display panel. Alternatively, the polarizer in the LCD display panel is directly omitted, which is not limited here.

在3D显示模式时，如图10b所示，第一透明电极04和第二透明电极05未加电压，液晶层03中的液晶沿第一方向平行排列，对通过的偏振光无作用，下基板02具有的凸透镜结构对通过的偏振光进行调制，使其在凸透镜结构的焦点汇聚。In the 3D display mode, as shown in Figure 10b, no voltage is applied to the firsttransparent electrode 04 and the secondtransparent electrode 05, and the liquid crystals in theliquid crystal layer 03 are arranged in parallel along the first direction, which has no effect on the passing polarized light. The convex lens structure of 02 modulates the passing polarized light so that it converges at the focal point of the convex lens structure.
