Description

3D显示装置及 3D显示方法 技术领域
本发明属于 3D (Three Dimensions) 显示领域， 更具体地讲， 涉及一种具 有 OLED (Organic Light Emitting Diode)显示器的 3D显示装置和 3D显示方 法。

有机发光二极管 （Organic Light Emitting Diode, OLED) 显示器具有自发 光的特色， 无需背光源， 可以做得更轻、 更薄的同时， 还具有省电、 节约成本 等优点； 而且， 有机发光二极管显示器具备高亮度、 宽视角、 高对比度、 可挠 曲、 低能耗的特性， 因此受到广泛的关注。
有机发光二极管显示器包括主动式有机发光二极管（Active Matrix Organic Light Emitting Diode , AMOLED ) 显示器和被动式有机发光二极管 （Passive Matrix Organic Light Emitting Diode ， PMOLED)显示器。 AMOLED显示器具 有可大尺寸化、 省电、 高解析度、 面板寿命长等优点， 在显示屏幕朝向大尺寸 全彩色方向发展的今天倍受青睐。
AMOLED显示器包括衬底， 薄膜晶体管 （Thin Film Transistor, TFT) 基 板， 有机发光层 （即 OLED层）和阴极基板层。 其中， TFT作为开关来控制流 向每个像素的电流流向； 有机发光层则在电场驱动下， 通过载流子注入和复合 而发光。 有机发光二极管发光原理是用氧化铟锡 （Indium Tin Oxide, ITO) 透 明电极和金属电极分别作为器件的阳极和阴极， 在一定电压驱动下， 电子和空 穴分别从阴极和阳极注入到电子和空穴传输层， 电子和空穴分别经过电子和空 穴传输层迁移到发光层， 并在发光层中相遇， 形成激子并使发光分子激发， 后 者经过辐射弛豫而发出可见光。辐射光可从 ΙΤΟ—侧观察到， 金属电极膜同时 也起了反射层的作用。
3D显示技术已成为目前显示领域的发展趋势。 目前， 3D显示技术一般是 采用双目视差原理来实现， 即将两幅视差图像 （即左、 右视差图像） 显示在二 维显示屏上， 然后利用一定的技术使观看者的左、 右眼分别只能看到显示屏上 的左、 右视差图像。
现有的 3D显示技术主要包括偏振光 3D显示技术、快门 3D显示技术和分 色 3D显示技术。 其中， 偏振光 3D显示技术一般采用分割空间的方法， 因而 会损失一半的分辨率， 降低了 3D显示的效果，视角也受到影响且易引起串扰; 快门 3D显示技术一般采用分割时间的方法， 容易引起画面闪烁， 也易引起串 扰； 分色 3D显示技术利用互补色原理并滤掉了大部分颜色， 使得画面颜色严 重失真、 亮度也严重下降， 因而大大降低了 3D显示的效果。 发明内容
为解决上述现有技术所存在的问题， 本发明的目的在于提供一种 3D显示 装置及 3D显示方法， 使第一图像 （即左视差图像） 和第二图像 （即右视差图 像） 高度分离； 而且反应速度较快、 对比度更高、 视角较大。

如前所述， 本发明针对现有技术中的缺陷， 提供了一种 3D显示装置， 包 括显示单元和眼镜， 其中， 所述显示单元包括多个紫外发光像素和多个可见发 光像素， 所述眼镜至少包括第一镜片和第二镜片， 所述第一镜片用于将所述紫 外发光像素发出的紫外光转换成可见光， 所述第二镜片用于直接接收所述可见 发光像素发出的可见光。
进一步地， 所述显示单元优选地采用有机发光二极管 （ Organic Light Emitting Diode, OLED) 显示器； 所述第一镜片优选地采用荧光镜片。 为了更好地阐述本发明的技术特点和结构， 以下结合实施例及其附图进行 详细描述。 在以下实施例中， 优选地， 采用可大尺寸化的主动式有机发光二极 管 (Active Matrix Organic Light Emitting Diode, AMOLED )显示器作为显示单 元为例进行详细说明， 当然， 显示单元也可以采用其他的有机发光二极管显示 器（例如被动式有机发光二极管（Passive Matrix Organic Light Emitting Diode ， PMOLED) 显示器） 或者能实现本发明目的的其他类型显示器。 图 1为本发明一实施例提供的 3D显示装置的显示单元的像素分布示意图。 如图 1所示， 本发明一实施例提供的 3D显示装置的显示单元包括多组沿 方向 A (即行方向） 交错排列的紫外发光像素 110和可见发光像素 120， 而在 方向 B (即列方向） 上均为紫外发光像素 110或可见发光像素 120， 其中， 紫 外发光像素 110包括第一紫外发光亚像素 111、 第二紫外发光亚像素 112和第 三紫外发光亚像素 113， 可见发光像素 120包括第一可见发光亚像素 121、 第 二可见发光亚像素 122和第三可见发光亚像素 123。第一紫外发光亚像素 111、 第二紫外发光亚像素 112和第三紫外发光亚像素 113为可以提供不同波长紫外 光的多个相邻的有机发光二极管电路， 其中紫外光的发光波长由有机发光二极 管电路的发光材料控制， 其发光材料可以为含咔唑类、 含芴类、 含三苯胺类、 五联苯类等有机化合物； 第一可见发光亚像素 121、 第二可见发光亚像素 122 和第三可见发光亚像素 123为可以提供不同可见色光的多个相邻的有机发光二 极管电路， 其中可见光的发光波长由有机发光二极管电路的发光材料控制。在 本实施例中，不同可见色光分别为红光、绿光和蓝光。在一些其他的实施例中， 不同可见色光还可以包括黄光， 即可见发光像素可以提供的不同组合的多种可 见色光， 例如红光、 绿光、 蓝光和黄光。
在每个紫外发光像素 110中， 第一紫外发光亚像素 111、 第二紫外发光亚 像素 112和第三紫外发光亚像素 113沿行方向 A顺序排列；在每个可见发光像 素 120中， 第一可见发光亚像素 121、 第二可见发光亚像素 122和第三可见发 光亚像素 123也沿行方向 A顺序排列。 同时， 紫外发光像素 110和可见发光像 素 120沿行方向 A依次间隔排列。 当然， 在本发明中， 显示单元的像素排布并不以图 1所示为限， 在另一实 施例中， 如图 2所示， 在每个紫外发光像素 110中， 第一紫外发光亚像素 111、 第二紫外发光亚像素 112和第三紫外发光亚像素 113沿行方向 A顺序排列；在 每个可见发光像素 120中，第一可见发光亚像素 121、第二可见发光亚像素 122 和第三可见发光亚像素 123也沿行方向 A顺序排列；而紫外发光像素 110和可 见发光像素 120沿方向 B依次间隔排列。换句话说， 紫外发光像素 110和可见 发光像素 120沿方向 B交错排列， 而在方向 A上均为紫外发光像素 110或可 见发光像素 120。
或者， 在另一实施例中， 如图 3所示， 紫外发光像素 110和可见发光像素 120沿方向 A交错排列，而在方向 B上均为紫外发光像素 110或可见发光像素 120； 而在每个紫外发光像素 110中， 第一紫外发光亚像素 111、 第二紫外发光 亚像素 112和第三紫外发光亚像素 113沿行方向 B顺序排列；在每个可见发光 像素 120中， 第一可见发光亚像素 121、 第二可见发光亚像素 122和第三可见 发光亚像素 123也沿行方向 B顺序排列。 或者， 在另一实施例中， 如图 4所示， 紫外发光像素 110和可见发光像素 120沿方向 B交错排列，而在方向 A上均为紫外发光像素 110或可见发光像素 120； 而在每个紫外发光像素 110中， 第一紫外发光亚像素 111、 第二紫外发光 亚像素 112和第三紫外发光亚像素 113沿行方向 A顺序排列；在每个可见发光 像素 120中， 第一可见发光亚像素 121、 第二可见发光亚像素 122和第三可见 发光亚像素 123也沿行方向 A顺序排列。 当然， 在本发明中， 紫外发光像素 110和可见发光像素 120也可以采用其他的方式来进行排列。
参照图 1和图 5， 本实施例提供的 3D显示装置还包括眼镜， 其中， 眼镜 至少包括第一镜片 210和第二镜片 220， 其中， 第一镜片 210为荧光镜片， 其 用于将所述紫外发光像素 110发出的紫外光转换成可见光； 第二镜片 220为普 通的光学镜片，其用于直接接收可见发光像素 120发出的可见光，第二镜片 220 除了对可见发光像素 120发出的可见光的光谱强度（即光强）进行一定比例的 衰减 （下面将详细描述）， 其并不对可见发光像素 120发出的可见光做其他任 何改变。 为了匹配可见发光像素 120所发出的可见光， 紫外发光像素 110中第 一紫外发光亚像素 111、 第二紫外发光亚像素 112和第三紫外发光亚像素 113 的发光波长要与第一镜片 210相匹配， 当紫外发光像素发出的紫外光透过眼镜 的第一镜片 210后， 第一镜片 210用于将所述第一紫外发光亚像素、 第二紫外 发光亚像素和第三紫外发光亚像素所发射的紫外光分别转换为三原色光， 即红 光、 绿光和蓝光， 因此， 第一紫外发光亚像素、 第二紫外发光亚像素和第三紫 外发光亚像素所发出的紫外光的波长是各不相同的。 例如， 第一镜片 210用于 将所述第一紫外发光亚像素所发射的紫外光转换为红光； 第一镜片 210用于将 所述第二紫外发光亚像素所发射的紫外光转换为绿光； 第一镜片 210用于将所 述第三紫外发光亚像素所发射的紫外光转换为蓝光。
由于第一镜片 210将紫外光转换为可见光后， 转换后的可见光的亮度要小 于转换前的紫外光的亮度， 因此， 为了消除透过第一镜片 210和第二镜片 220 画面的亮度差， 第二镜片 220的透光率由紫外发光像素所发出的紫外光的光谱 强度 （即光强） 与该紫外光透过第一镜片 210后转换为可见光的光谱强度 （即 光强）所确定， 即第二镜片 220的透光率为紫外发光像素所发出的紫外光透过 第一镜片 210后转换为可见光的光谱强度 （即光强）与紫外发光像素所发出的 紫外光的光谱强度 （即光强） 的比值。 其中一种较为优选的是： 紫外发光像素 所发出的紫外光透过第一镜片 210后转换为可见光的亮度与可见发光像素所发 出的可见光透过第二镜片 220后的亮度的比为 1:1。 本实施例提供的 3D显示原理如图 5所示。 在紫外发光像素 110发出紫外 光的光谱图 （图 5中 （a) 图所示） 中， 其光谱频率在紫外光范围内。 当紫外 发光像素 110发出的紫外光透过眼镜中的第一镜片 210后， 紫外发光像素 110 发出的紫外光会发生红移现象， 这样， 第一镜片 210将所述紫外发光像素 110 发出的紫外光转换成可见光， 转换成的可见光的光谱频率在可见光范围内， 如 图 c所示。 在可见发光像素 120发出可见光的光谱图 （图 5中 （b ) 图所示） 中， 其光谱频率在可见光范围内。 当可见发光像素 120发出的可见光透过眼镜 中的第二镜片 220后，第二镜片 220可改变可见发光像素 120发出的可见光的 亮度来匹配紫外发光像素 110发出的紫外光透过第一镜片 210后转换成的可见 光的亮度， 其发光光谱如图 5中的 （c) 图所示。 由第一镜片 210转换成的可 见光与通过第二镜片 220的可见光共同进入观看者的视网膜， 进而合成 3D画 面。
本发明还提供了一种基于上述 3D显示装置的 3D显示方法，具体参照图 6， 其示出基于上述 3D显示装置的 3D显示方法的流程示意图。
如图 6所示， 基于上述 3D显示装置的 3D显示方法包括：
51、 控制多个紫外发光像素发出紫外光而显示第一画面（即左视差图像）， 同时控制多个可见发光像素发出可见光而显示第二画面 （即右视差图像）。
52、 利用第一镜片将所述紫外发光像素发出的紫外光转换成可见光， 同时 利用第二镜片直接接收所述可见发光像素发出的可见光。
本发明的实施例提供的 3D显示装置， 包括具有多个紫外发光像素和多个 可见发光像素的显示单元和与之相配合的眼镜， 在裸眼的情况下， 可见光像素 能够通过人眼进入视网膜形成 2D显示画面。 佩戴眼镜后， 紫外发光像素发出 的紫外光通过为荧光镜片的第一镜片而红移至可见光， 与通过第二镜片的可见 光共同进入观看者的视网膜， 合成 3D画面。 因此该 3D显示装置可使左、 右 视差图像高度分离； 而且该装置反应速度快、 对比度高、 视角大、 3D显示效 果好。 需要说明的是， 在本文中， 诸如第一和第二等之类的关系术语仅仅用来将 一个实体或者操作与另一个实体或操作区分开来， 而不一定要求或者暗示这些 实体或操作之间存在任何这种实际的关系或者顺序。 而且， 术语 "包括"、 "包 含"或者其任何其他变体意在涵盖非排他性的包含， 从而使得包括一系列要素 的过程、 方法、 物品或者设备不仅包括那些要素， 而且还包括没有明确列出的 其他要素， 或者是还包括为这种过程、 方法、 物品或者设备所固有的要素。在 没有更多限制的情况下， 由语句 "包括一个…… "限定的要素， 并不排除在包 括所述要素的过程、 方法、 物品或者设备中还存在另外的相同要素。 虽然本发明是参照其示例性的实施例被具体描述和显示的， 但是本领域的 普通技术人员应该理解， 在不脱离由权利要求限定的本发明的精神和范围的情 况下， 可以对其进行形式和细节的各种改变。
