3D, 也可称之为三维立体或三维， 3D 成像技术不同于二维平面成像技 术， 将三维图像信息压缩到一个二维平面中， 势必会使图像失真， 不能准备的 反应图像中各个像素点真实空间位置，二维平面所展示的三维图像是通过色彩 的明暗、 物体的大小等信息来表达的， 人们通过心理暗示作用再结合二维平面 中的色彩的明暗、物体的大小等信息来主观判断二维平面中的各个像素点离人 眼的距离， 而不是真实的物理景深。
三维显示区别于二维就是要用各种方法给观看者带来视觉的深度感知， 使之自然或不自然获得画面中第三维度的信息，这种感知方法对人眼来说就是 真三维和假三维的区别。 所以， 对于三维立体成像技术而言， 还原三维立体空 间中的真实物理景深非常重要，是也是使人眼能够感知到三维立体图像的最关 键的因素。
目前普遍存在的需要佩戴眼镜的三维显示技术是利用双眼视差的原理来 实现的， 佩戴眼镜在短时间内观看静态的立体图像时并不明显， 但当观看立体 电视时， 由于人眼长时间处于这种不十分自然且紧张的观看状态， 便会感到极 不舒适及非常疲劳。 另一方面由于需要佩戴眼镜观看， 所以只适合于观看电影 等特殊场合， 对于广告展示来说是不可能的， 而且佩戴的眼镜对光线具有过滤 作用， 所以导致观看图形时光线较暗， 对眼睛非常不好。
所以目前越来越多的人热衷于研究棵眼三维显示技术， 目前的棵眼三维 显示技术主要有光屏障式（Barrier ), 柱状透镜 (Lenticular Lens)技术、 指向光 源（ Directional Backlight ), MLD三维显示技术、 全息三维技术以及体三维显 示技术六种。棵眼式 3D技术最大的优势便是摆脱了眼镜的束缚，但是分辨率、 可视角度和可视距离等方面还存在很多不足。
光屏障式三维显示技术利用了安置在背光模块及 LCD 面板间的视差障 壁， 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 条紋会遮挡右眼； 同理， 应该由右眼看到的图像显示在液晶屏上时， 不透明的 条紋会遮挡左眼， 通过将左眼和右眼的可视画面分开， 使观者看到 3D影像。 光屏障式三维显示技术的优点是与既有的 LCD液晶工艺兼容， 因此在量产性 和成本上较具优势， 但是缺点是采用此种技术的产品影像分辨率和亮度会下 降， 而且可视角度也有限制。
柱状透镜三维显示技术的原理是在液晶显示屏的前面加上一层柱状透 镜， 使液晶屏的像平面位于透镜的焦平面上， 这样在每个柱透镜下面的图像的 像素被分成几个子像素， 这样透镜就能以不同的方向投影每个子像素。 于是双 眼从不同的角度观看显示屏， 就看到不同的子像素。 柱状透镜三维显示技术的 虽然相比视差屏障三维显示技术而言， 图像的亮度不会降低， 但是分辨率依然 会下降， 而且相关制造与现有 LCD液晶工艺不兼容， 需要投资新的设备和生 产线， 成本较高。
指向光源 （Directional Backlight ) 3D 技术实现的方法是通过搭配两组
LED,配合快速反应的 LCD面板和驱动方法，让 3D内容以排序方式进入观看 者的左右眼， 由于互换影像产生视差， 进而让人眼感受到 3D三维效果。 这种 技术具有很大的优势， 在 3D显示的亮度和分辨率上都能够得到保障， 但是由 于其还是利用了人们的左右目艮视差原理来使图像在人的大脑中加工形成三维 图像， 所以人在观看的时间较长之后还是容易出现疲劳， 头晕等现象。
2009年 4月， 美国 PureDepth公司宣布研发出改进后的棵眼 3D技术 —— MLD ( multi-layer display多层显示）， 这种技术能够通过一定间隔重叠的 两块液晶面板， 实现在不使用专用眼镜的情况下， 观看文字及图画时所呈现 3D影像的效果。 本技术由于只有两块液晶面板， 所以呈现的影像的景深有限， 三维显示效果较差， 而较多的液晶面板又会降低显示影像的亮度。 全息三维技术利用镜面反射镜像的原理能够产生非常逼真的立体效果，但 在动态显示方面需要非常高的空间光调制器以及超高速的数据处理系统，这两 个技术限制了这种技术的发展， 使之目前还不能很好的运用到现实生活中。
体三维显示技术则与其他立体显示技术不同的是，它是真正能够实现动态 效果的 3D技术， 它可以让你看到科幻电影中一般"悬浮"在半空中的三维透视 图像。 体三维显示技术目前大体可分为扫描体显示 （Swept- Volume Display), 和固态体显示 （Solid-Volume Display)两种。
全息三维技术以及体三维显示技术相比光屏障式 （Barrier ), 柱状透镜 (Lenticular Lens)技术、 指向光源（ Directional Backlight )三维显示技术而言， 各像素点或者各像素点的像不在同一个平面上， 具有真实的景深， 所以观看 3D影像时， 用户不会产生眩晕、 头痛及眼睛疲劳等副作用， 而且屏幕的分辨 率和亮度不会降低， 对观看 3D影像的视觉及角度没有太大的限制， 但是由于 体视三维显示设备相比普通的 2D显示设备而言结构要复杂很多， 而且由于结 构的因素， 所以体积较大， 成本较高， 而且其不与现有的 LCD面板兼容， 所 以开发生产成本更高。
【发明内容】
本发明的目的就是为了解决现有技术存在的问题，提出了一种电致折射率 改变的 3D显示设备和显示方法。
本发明的构思如下：
对于二维显示屏（例如液晶显示屏）而言， 各像素点在同一平面上， 所以 显示的画面为二维画面， 但是如果有一种显示设备的各像素点不在同一平面 上， 各像素点离人眼的距离与实际所显示的三维画面的景深相对应， 而由于各 像素点显示不同的画面时离人眼的距离不同，所以各像素点离人眼的距离是变 化的， 由于像素点非常小， 所以采用机械的方式移动像素点几乎是不可能的， 但是我们可以将各像素点的虚像（由于像素点与其像均在人眼的同侧， 所以其 必定为虚像）离人眼的距离与实际所显示的三维画面的景深相对应， 即离人眼 距离最远的像素点的虚像所对应的像素点显示的画面的景深最远。 而根据筷子在水中成像的原理可知， 方形柱状体的折射率越大， 在方形柱 状体与人眼相对的面的物体在人眼中成像离人眼越近， 所以， 根据这个原理， 只要我们改变方形柱状体的折射率， 即可改变该物体在人眼中成像离人眼距离 的远近， 将每一个方形柱状体与各像素点相对应， 即可实现各像素点在人眼中 所称的虚像距离人眼的距离不同， 从而形成真实的物理景深。
本发明的具体技术方案如下：
本发明提供一种基于电致折射率改变的 3D显示设备， 该设备包括二维平 面显示屏、 一设置于显示屏前端的平板状的透明电光晶体阵列， 所述电光晶体 阵列由与显示屏像素点相同数量的方柱状的电光晶体组成，每个电光晶体的与 显示屏平行的截面与显示屏像素点的大小相同，且各电光晶体与显示屏像素点 相正对， 该 3D显示设备还包括向各电光晶体施加电压的透明电极以及与电极 电性连接的控制模块，所述控制模块用于控制电极向电光晶体施加与该电光晶 体相正对像素点的景深相对应的电压。
各电光晶体为一次电光效应晶体。
所述各电光晶体为横向电光效应晶体， 所述电极相对设置电光晶体的两 侧， 设置在电光晶体两侧的电极与电光晶体阵列垂直， 且设置在电光晶体两侧 的两电极相互平行。
横向相邻的电光晶体之间共用一电极，纵向相邻的电光晶体之间分布有连 接电极和控制模块的透明导线， 导线与电极垂直。
所述电光晶体为钽铌酸锂或钽铌酸钾。
所述透明电光晶体阵列的厚度为 1 mm~1 m。
所述二维显示屏为液晶显示屏。
本发明还提供一种基于电致折射率改变的 3D显示方法， 该方法包括： 在二维显示屏前端设置平板状的透明电光晶体阵列，所述电光晶体阵列由 与二维显示屏像素点相同数量的方柱状的电光晶体组成，每个电光晶体的与显 示屏平行的截面与二维显示屏像素点的大小相同，且各电光晶体与二维显示屏 像素点相正对，通过一控制模块向电光晶体施加与该电光晶体相正对像素点的 景深相对应的电压。
所述各电光晶体为横向电光效应晶体，所述控制模块与向电光晶体施加电 压的电极电性连接， 所述电极相对设置电光晶体的两侧， 设置在电光晶体两侧 的电极与电光晶体阵列垂直， 且设置在电光晶体两侧的两电极相互平行。
横向相邻的电光晶体之间共用一电极，纵向相邻的电光晶体之间分布有连 接电极和控制模块的透明导线， 导线与电极垂直。
与该电光晶体相正对的像素点的景深与各电光晶体施加的电压的一次方 成反比。
所述电光晶体为钽铌酸锂或钽铌酸钾。
所述透明电光晶体阵列的厚度为 1 mm~1 m。
所述二维显示屏为液晶显示屏。
本发明有益的技术效果在于：
相较于现有技术， 本发明利用筷子在水中成像的原理， 将电光晶体阵列设 置于二维显示屏的前面即可实现真实的物理景深， 结构筒单， 成本低廉， 体积 较小。 而且本发明的 3D显示设备所显示的影像可以棵眼光看， 而且由于各像 素点在电光晶体中所成的像为等大的虚像，所以其该显示设备显示的三维影像 的分辨率、 亮度均没有改变， 由于具有真实的物理景深， 所以在观看本发明的 3D显示设备所显示的三维影像时不会出现疲劳的问题。
由于本发明可以在现有的二维显示设备上改进，所以可以直接在现有的液 晶显示面板加工和改进即可实现， 升级成本低廉。
而且本发明的 3D显示设备可以实现二维和三维显示的转换， 能够满足人 们的多种观看需要。
本发明将各电光晶体之间的电极设置在电光晶体的两侧，且与二维显示屏 垂直， 同时横向相邻的电光晶体之间共用电极， 能够使得两电光晶体之间的间 隔非常小， 从而不影响显示设备的分辨率， 另一方面， 通过共用电极， 节省了 材料成本。
【附图说明】 图 1为本发明的原理示意图；
图 2为本发明实施例显示设备侧面结构示意图；
图 3为本发明实施例显示设备正面结构示意图；

【具体实施方式】
为了使发明的目的、技术方案及优点更加清楚明白， 以下结合附图及实施 例， 对本发明进行进一步详细说明。 应当理解， 此处所描述的实施例仅用以解 释本发明， 并不用来限定本发明。
在介绍本发明的实施例之前， 先介绍下本发明的原理， 如图 1 中的 （a ) 图所示， 在透明的方形柱状晶体 10的下方为一物体 20, 在该透明的方形柱状 晶体 10的上方为人眼 30, 根据折射原理， 人眼 30透过该透明的方形柱状晶 体 10所看到的物体 20的像 40a, 实际上要比实际的物体离人眼的距离要近， 当将该透明的方形柱状晶体 10 的折射率调高， 而该透明的方形柱状晶体 10 的形状和大小不变， 同时该方形柱状晶体 10与物体 20的相对位置也不变，如 图 1 中的（b )图所示，则会发现，人眼透过该晶体 10观看到物体 30的像 40b 要比之前的像 40a距离人眼的距离要更近一点， 即物体 20透过该晶体 10在 人眼中的成虚像离人眼的距离发生了改变， 而虚像的大小没有发生改变。 所以 可以根据折射率的调整来调整显示屏的各像素点所显示的画面在人眼中所称 虚像的距离， 从而对不同的像素点进行区别调整， 从而形成整个画面的景深。
根据上述的原理， 本发明提供了一种基于电致折射率改变的 3D显示设备 和显示方法。
实施例 1
如图 2-4所示， 本实施例提供了一种基于电致折射率改变的 3D显示设备 50, 该设备 50包括一个二维液晶平板显示屏 51、 一设置于该显示屏 51前端 (即该显示屏 51显示面的前方）的平板状的透明电光晶体阵列 52, 所述电光 晶体阵列 52由多个相同形状和大小的电光晶体 521组成， 每个电光晶体 521 的形状为长方体形的柱状， 且柱状体的底面为正方形， 柱状体的底面 5211 与 显示屏 51相对，所述液晶平板显示屏 51包括多个相同大小的方形像素点 511 , 柱状体的地面 5211与像素点 511的大小相同，各电光晶体 521与各像素点 511 相正对， 在各电光晶体 521的相对的两侧面 5212分别设置有两透明导电材料 制成的平板形电极 5213, 两电极 5213的大小与两侧面 5212的大小相同 （两 电极 5213也可比两侧面 5212小）， 且两电极 5213与显示屏垂直， 在两各电 光晶体 521 的分界线上分布有连接电极的导线 5214, 所述导线 5214也是采 用透明材料制成。所述各电光晶体 521为横向电光效应晶体，横向相邻的电光 晶体之间共用一电极 5213,纵向相邻的电光晶体之间分布连接电极 5213的透 明导线 5214, 连接电极的导线 5214与电极 5213垂直。
各电光晶体外包覆有一层透明的绝缘薄膜（图中未示出）， 以防止电光晶 体的导电性能对电极的影响。
该显示设备还包括一控制模块 53, 所述导线 5214连接电极和控制模块 53,控制模块 53控制向电光晶体 521施加与该电光晶体 521相正对像素点的 景深相对应的电压， 具体的， 本实施例中， 与该电光晶体相正对的像素点的景 深与各电光晶体施加的电压的一次方成反比， 由于横向相邻的电光晶体之间用 电极 5213, 所以控制模块 53控制位于各电光晶体之间的电极的电量的大小， 从而控制向各电光晶体施加的电压。
在本实施例中所述电光晶体为钽铣酸锂或钽铣酸钾，所述电光晶体阵列的 厚度为 2cm (厚度最小为 1 mm , 厚度最大为 1 mm ), 所述电极和导线材料为 Zn〇。
如图 5所示， 本实施例还提供一种采用上述基于电致折射率改变的 3D显 示设备从而实现 3D显示方法， 该方法包括：
S1： 获取所显示 3D图像各像素点的景深数据；
S2:计算向电光晶体施加的与该电光晶体相正对的像素点的景深成反比的 电压；
S3: 计算位于两电光晶体之间的电极的电量大小；
S4: 通过控制模块向两电光晶体之间的电极施加相应的电量。 通过上述的 3D显示设备以及显示方法， 可以通过控制模块控制向各晶体 施加的电压， 从而达到控制各晶体的折射率的目的， 当人眼通过各晶体看到的 各像素点所成的虚像离人眼的距离与实际上要显示的三维景物各像素点的物 理景深成正比时，则人眼可以通过该显示设备看到真实的具有物理景深的三维 影像， 可以实现棵眼光看的目的。 总之， 以上实施例仅用以说明本发明的技术方案而非限制， 尽管参照较佳 实施例对本发明进行了详细说明， 本领域的普通技术人员应当理解， 可以对本 发明的技术方案进行修改或者等同替换， 而不脱离本发明技术方案的精神和范 围， 其均应涵盖在本发明的权利要求范围当中。
