液晶透镜和立体显示装置技术领域 The liquid crystal lens and a stereoscopic display apparatus Technical Field

[0001] 本发明涉及液晶技术领域,尤其涉及液晶透镜和立体显示装置。 [0001] The present invention relates to liquid crystal technology, and more particularly relates to a stereoscopic display device and a liquid crystal lens.

背景技术 Background technique

[0002] 人的双眼基本处于同一平面,但两眼间有一定的间距,因此观看物体时视线会形成一个交叉角度,角度越大,立体感和距离感就越强。 [0002] The human eye substantially in the same plane, but there is a certain distance between the eyes, so the line of sight when viewing the object will form a crossing angle, the larger the angle, the greater the sense of distance and three-dimensional sense. 由于交叉角度的存在,双眼看到的画面并不相同,也就是产生了“视差”,两幅具有视差的画面经过大脑处理后得到完整的立体影像,或者说三维(three-dimensional,简称3D)影像。 Because of the crossing angle, the eyes do not see the same picture, which is produced "parallax", two images having parallax brain after treatment to obtain a complete three-dimensional image, or three dimensional (three-dimensional, referred to as 3D) image. 裸眼就是说不用戴3D眼镜也可以看得出3D效果。 That is the naked eye without wearing 3D glasses you can also see the 3D effect.

[0003] 立体显示设备是利用人眼视差的特征来显示3D效果。 [0003] The stereoscopic display device using characteristics of the human eye to display parallax 3D effect. 通常立体显示设备将具有视差的图片输出到立体显示器上,然后将这种立体视差图片传送给观看者的左右眼,进而合成立体图像。 Typically the stereoscopic display device having a parallax image output to the stereoscopic display, and then transfers this image to a stereoscopic disparity of the viewer's left and right eyes, and thus a stereoscopic image synthesis.

[0031] 液晶层14设置于第一电极结构12和第二电极结构16之间,其包括沿初始排列方向排列的多个液晶分子。 [0031] The liquid crystal layer 14 disposed between the first electrode structure 12 and the second electrode structure 16, which comprises a plurality of liquid crystal molecules are aligned along the initial alignment direction. 第一配向层13设置于液晶层14与第一电极结构12之间,第二配向层15设置于液晶层14与第二电极结构16之间。 A first alignment layer 13 is disposed between the liquid crystal layer 14 and the first electrode structure 12, a second alignment layer 15 disposed between the structure 14 and the second electrode 16 of the liquid crystal layer. 液晶层14内包括有沿初始排列方向排列的液晶分子。 The liquid crystal layer 14 includes liquid crystal molecules in the initial alignment direction of the arrangement. 第一配向层13和第二配向层15相互配合以使液晶分子沿初始排列方向排列。 A first alignment layer 13 and the second alignment layer 15 cooperate with each other so that the liquid crystal molecules are aligned along the initial alignment direction.

[0032] 液晶透镜的产生过程,如下所述: [0032] The production process of the liquid crystal lens, as follows:

在第一条形电极组121a上施加第一电压VI,在第一条形电极组121b上施加零电压或参考电压Vref。 Applying a first voltage VI on the first strip electrode group 121a, or zero voltage is applied to the reference voltage Vref on the first strip electrode group 121b. 这样,在第一条形电极组121a和第一条形电极组121b形成一电压差,进而产生电场。 Thus, the first strip electrode group 121a and the first strip electrode group 121b is formed a difference voltage, thereby generating an electric field. 液晶层14内的液晶分子在电场的作用下排列方向发生改变,根据液晶分子在液晶层14内的排布情况,不同区域的液晶分子的偏向角度不同,使得液晶分子的折射率呈现抛物线形变化,进而形成透镜,达到使得液晶层14具有透镜的效果,相邻的两个第一条形电极121之间的液晶分子的折射率呈现抛物线形变化,形成透镜。 Liquid crystal molecules in the liquid crystal layer 14 under the action of an electric field changes the arrangement direction, the liquid crystal molecular arrangement in the case of the liquid crystal layer 14, the deflection angle of the liquid crystal molecules different in different regions, so that the refractive index of the liquid crystal molecules exhibits a parabolic change , thus forming a lens, to the liquid crystal layer 14 having a lens effect, the refractive index of the liquid crystal molecules between two adjacent first strip electrode 121 exhibits a parabolic change, the lens is formed.

[0033] 在第二条形电极组161a上施加零电压或参考电压Vref (或者说第二条形电极组161a与第一条形电极组121b相互电性连接),在第二条形电极组161b上施加第一电压Vl(或者说第二条形电极组161b与第一条形电极组121a相互电性连接)。 [0033] The zero voltage is applied on the second strip electrode group 161a or the reference voltage Vref (or the second strip electrode groups 161a and 121b of the first set of stripe-shaped electrodes electrically connected to each other), the second strip electrode groups applying a first voltage Vl (or the second strip electrode group 161b and the first strip electrode group 121a is electrically connected to each other) on 161b. 这样,在第二条形电极组161a和第二条形电极组161b形成一电压差,进而产生电场。 Thus, the second strip electrode group 161a and the second strip electrode group 161b is formed a difference voltage, thereby generating an electric field. 液晶层14内的液晶分子在电场的作用下排列方向发生改变,根据液晶分子在液晶层14内的排布情况,不同区域的液晶分子的偏向角度不同,使得液晶分子的折射率呈现抛物线形变化,进而形成透镜,达到使得液晶层14具有透镜的效果,相邻的两个第二条形电极161之间的液晶分子的折射率呈现抛物线形变化,形成透镜。 Liquid crystal molecules in the liquid crystal layer 14 under the action of an electric field changes the arrangement direction, the liquid crystal molecular arrangement in the case of the liquid crystal layer 14, the deflection angle of the liquid crystal molecules different in different regions, so that the refractive index of the liquid crystal molecules exhibits a parabolic change , thus forming a lens, to the liquid crystal layer 14 having a lens effect, the refractive index of the liquid crystal molecules between two adjacent second strip electrode 161 exhibits a parabolic change, the lens is formed.

[0034] 另外,在第一条形电极组121a、第一条形电极组121b、第二条形电极组161a和第二条形电极组161b上施加的电压不局限于上述的一种方式,只要可以形成液晶透镜即可。 [0034] Further, the voltage applied to the 121b, the second strip electrode group 161a and the second strip electrode groups 161b first strip electrode group 121a, a first set of strip-shaped electrodes is not limited to the above-described way, As long as the liquid crystal lens can be formed.

[0035] 如果光线由垂直于第二基板17的方向入射,先经过相邻的两个第二条形电极161之间的液晶分子形成的透镜,再经过相邻的两个第一条形电极121之间的液晶分子形成的透镜,再由第一基板11射出。 [0035] If light is incident perpendicular to the direction of the second substrate 17, the first through the lens of the liquid crystal molecules between two adjacent second strip electrode 161 is formed, through two adjacent first strip electrode the liquid crystal molecules is formed between the lens 121, and then emitted by the first substrate 11.

[0036] 相较于现有技术,本发明实施例米用第一电极结构12和第二电极结构16各自分为2组电极(第一条形电极组121a和第一条形电极组121b,第二条形电极组161a和第二条形电极组161b),驱动方式简单。 [0036] Compared to the prior art, for example, 16 meters with the first electrode structure are each divided into two groups of electrodes (a first electrode group 121a and strip-shaped first strip electrode group 12 and the second electrode structure 121b embodiment of the present invention, The second strip electrode group 161a and the second strip electrode group 161b), a simple drive. 第一电极结构12和第二电极结构16电极区域很窄,光线透过率高。 First electrode structure 12 and second electrode structures electrode region 16 is narrow, high light transmittance. 第一条形电极组121a和第一条形电极组121b,第二条形电极组161a和第二条形电极组161b中心处电场方向为横向,因此中心处液晶分子排布平行度高,折射率分布理 The first electrode group 121a and strip-shaped first strip electrode group 121b, 161b the direction of the electric field at the center of the second electrode strip and the second strip electrode group 161a is set laterally, thus at the center of the liquid crystal molecules are arranged parallel to the high refraction rate distribution management
