Description

裸眼3D显示装置 技术领域
本发明涉及显示技术领域，特别是涉及一种裸眼3D显示装置。
 背景技术
随着显示技术的发展，越来越多的用户开始使用各种显示装置进行社交娱乐活动；特别是裸眼3D显示装置的使用，使得用户不需要使用任何外部装置（如3D眼镜）即可欣赏3D画面。
现有的裸眼3D显示装置主要是利用双眼视差的原理使人产生3D感觉，即通过对入射光的光路进行调节，使人的左眼能够接收到左眼影像，人的右眼能够接收到右眼影像，且左眼影像和右眼影像不会互相串扰。
现有的裸眼3D显示装置主要包括光栅式（barrier type）裸眼3D显示装置和透镜式（lens type）裸眼3D显示装置。
光栅式裸眼3D显示装置的结构如图1所示，其包括显示面板11以及光栅单板12，该光栅式裸眼3D显示装置主要是利用光栅档板对左眼影像L（或右眼影像R）进行遮挡，使得用户的左眼（或右眼）能够接收到左眼影像L（或右眼影像R），而不能接收到右眼影像R（或左眼影像L），使人能够欣赏到3D画面的效果。
透镜式裸眼3D显示装置的结构如图2所示，其包括显示面板21以及透镜22，该透镜式裸眼3D显示装置主要是利用透镜对入射光线不同方向的折射，使得用户的左眼（或右眼）接收到左眼影像L（或右眼影像R），而不能接收到右眼影像R（或左眼影像L），使人能够欣赏到3D画面的效果。
但是现有的裸眼3D显示装置一般由RGB三色子像素构成，其不同的子像素在空间不同位置是规则排列的。因此在裸眼3D显示装置中，由于光栅档板12或透镜22对入射光方向的调节以及光线的放大，使用户观看裸眼3D显示装置时会看到RGB子像素交替的彩色条纹或者黑白交替条纹，这种条纹就是摩尔纹，摩尔纹的产生会影响3D画面的显示质量。
为了改善裸眼3D显示装置产生的摩尔纹现象，裸眼3D显示装置的设计者会在光栅档板12（或透镜22）与显示面板11（或显示面板21）之间、或光栅档板12（或透镜22）外侧设置一散射屏（light diffuser）。这样由显示面板11（或显示面板21）发射出来的光线经散射屏后发生散射，导致产生的摩尔纹减轻。
虽然设置散射屏可以减轻摩尔纹，但是由于散射屏同时将左眼信号和右眼信号均进行了散射处理，导致最终显示画面的3D串扰变大，影响裸眼3D显示装置的显示品质。
故，有必要提供一种裸眼3D显示装置，以解决现有技术所存在的问题。

在图中，结构相似的单元是以相同标号表示。
请参照图3A-图3C，图3A为本发明的裸眼3D显示装置的第一优选实施例的结构示意图；图3B为本发明的裸眼3D显示装置的第一优选实施例的散射模块的结构示意图；图3C为本发明的裸眼3D显示装置的第一优选实施例的左眼画面和右眼画面的对比示意图。
本优选实施例的裸眼3D显示装置30包括显示面板31、裸眼3D面板32、画面比较模块33以及散射模块34。显示面板31用于显示左眼画面L以及右眼画面R；裸眼3D面板32用于对左眼画面L的出射光线的出射角度以及右眼画面R的出射光线的出射角度进行调整；画面比较模块33用于将左眼画面L的灰阶与对应位置的右眼画面R的灰阶进行比较，并产生比较结果；散射模块34用于根据比较结果，对左眼画面L的出射光线以及右眼画面R的出射光线中的至少部分进行散射处理。
在本优选实施例中，显示面板31为两视点显示面板，裸眼3D面板32为光栅式裸眼3D面板，散射模块34为聚合物分散液晶薄膜，该散射模块34设置在裸眼3D面板32的出光面上。
请参照图3B，图3B为本发明的裸眼3D显示装置的第一优选实施例的散射模块的结构示意图。聚合物分散液晶（polymer dispersed liquid crystal，PDLC）薄膜是一种通过调控电压控制透过率的智能调光薄膜。PDLC薄膜将分子液晶341分散于透明的聚合物基体中，聚合物为液晶微滴提供稳定的网络结构，分子液晶341形成微米或纳米尺寸的液晶微粒。该PDLC薄膜两端没有施加电压时，液晶分子341是无序排列的，入射光线入射之后在液晶分子341与聚合物基体的界面上多次折射与反射，显示出白色的散射态（如图3B的左图所示）。该PDLC薄膜两端施加电压时，液晶分子341会沿着电场的方向排列，从而入射光线入射之后不会发生反射和折射，而直接透射出去（如图3B的右图所示）。
因此聚合物分散液晶薄膜包括多个散射处理单元342以及多个电压施加单元343，散射处理单元342用于对显示面板31的不同位置的出射光线进行散射处理；电压施加单元343用于给相应的散射处理单元342施加控制电压。同时左眼画面L和对应的右眼画面R均包括多个画面比较区域311，画面比较区域311、散射处理单元342以及电压施加单元343一一对应，即散射处理单元342可通过相应的电压施加单元343对相应的画面比较区域311的出射光线进行散射处理。
本优选实施例的裸眼3D显示装置30使用时，首先画面比较模块33对每个画面比较区域311的左眼画面L的灰阶和右眼画面R的灰阶进行比较。
如一画面比较区域311内的左眼画面L的灰阶与右眼画面R的灰阶的差值小于设定值，则认为左眼画面L和右眼画面R在灰阶上差异不大，对该画面比较区域311的出射光线进行散射处理并不会造成严重的左眼画面L和右眼画面R的串扰现象，同时还可减轻该画面比较区域311的摩尔纹现象。因此设定散射模块34对该画面比较区域311内的左眼画面L的出射光线以及右眼画面R的出射光线进行散射处理。
如一画面比较区域311内的左眼画面L的灰阶与右眼画面R的灰阶的差值大于等于设定值，则认为左眼画面L和右眼画面R在灰阶上差异较大，如对该画面比较区域311的出射光线进行散射处理，可能会造成比较严重的左眼画面L和右眼画面R的串扰现象；因此设定散射模块34不对所述画面比较区域311内的左眼画面L的出射光线以及右眼画面R的出射光线进行散射处理。
具体如图3C所示，其中A1和A2的画面比较区域311的左眼画面L和对应位置的右眼画面R的灰阶差异较大，表现出来即左眼画面L和右眼画面R在该画面比较区域311内为完全不同灰阶的物品，即设定散射模块34不对A1和A2区域的左眼画面L的出射光线以及右眼画面R的出射光线进行散射处理。
B1和B2的画面比较区域311的左眼画面L和对应位置的右眼画面R的灰阶差异较小，表现出来即左眼画面L和右眼画面R在画面比较区域311内为差不多相同灰阶的物品，即设定散射模块34对B1和B2区域的左眼画面L的出射光线以及右眼画面R的出射光线进行散射处理。
随后左眼画面L的出射光线和右眼画面R的出射光线由显示面板31出射，经光栅式裸眼3D面板调整左眼画面L的出射光线的出射角度以及右眼画面R的出射光线的出射角度（即将在左眼画面L的出射光线的光路上的右眼画面R的出射光线全部阻挡掉，以及将在右眼画面R的出射光线的光路上的左眼画面L的出射光线全部阻挡掉）。
然后散射模块34根据画面比较模块33的比较结果，对左眼画面L的出射光线以及右眼画面R的出射光线中的至少部分进行散射处理。
具体为：当画面比较模块33设定散射模块34对某个画面比较区域311的左眼画面L的出射光线以及右眼画面R的出射光线进行散射处理时，则散射模块34中对应的电压施加单元343不给相应的散射处理单元342施加控制电压，这样该画面比较区域311对应的聚合物分散液晶薄膜中的液晶分子341处于白色的散射态，即散射处理单元342对相应画面比较区域311的显示面板31的出射光线进行散射处理。
当画面比较模块33设定散射模块34不对某个画面比较区域311的左眼画面L的出射光线以及右眼画面R的出射光线进行散射处理时，则散射模块34中对应的电压施加单元343给相应的散射处理单元342施加控制电压，这样该画面比较区域311对应的聚合物分散液晶薄膜中的液晶分子341沿规则方向排列，即散射处理单元342对相应画面比较区域311的显示面板31的出射光线不会进行散射处理，该出射光线直接从散射模块34透射出去。
这样散射模块34即完成了左眼画面L的出射光线以及右眼画面R的出射光线（显示面板31的出射光线）中的至少部分的散射处理。
最后散射模块34处理后的出射光线被人眼接收，这样用户可以欣赏到串扰现象小以及摩尔纹现象也较小的3D显示画面。
本优选实施例的裸眼3D显示装置通过设置画面比较模块以及散射模块，对部分显示画面的出射光线进行散射处理，可以在不增大显示画面的串扰的基础上，减少裸眼3D显示装置的摩尔纹现象。
请参照图4，图4为本发明的裸眼3D显示装置的第二优选实施例的结构示意图。本优选实施例的裸眼3D显示装置40包括显示面板41、裸眼3D面板42、画面比较模块43以及散射模块44。本优选实施例和第一优选实施例的区别在于散射模块44设置在显示面板41以及裸眼3D面板42之间。
本优选实施例的裸眼3D显示装置40使用时，首先画面比较模块43对每个画面比较区域的左眼画面L的灰阶和右眼画面R的灰阶进行比较。
随后左眼画面L的出射光线和右眼画面R的出射光线有由显示面板41出射。
然后散射模块44根据画面比较模块43的比较结果，对显示面板41出射的左眼画面L的出射光线以及右眼画面R的出射光线中的至少部分进行散射处理。
最后散射模块44处理后的出射光线经光栅式裸眼3D面板调整后被人眼接收，这样用户同样可以欣赏到串扰现象小以及摩尔纹现象也较小的3D显示画面。
本优选实施例的裸眼3D显示装置通过设置画面比较模块以及散射模块，对部分显示画面的出射光线进行散射处理，可以在不增大显示画面的串扰的基础上，减少裸眼3D显示装置的摩尔纹现象。
请参照图5，图5为本发明的裸眼3D显示装置的第三优选实施例的结构示意图。本优选实施例的裸眼3D显示装置50包括显示面板51、裸眼3D面板52、画面比较模块53以及散射模块54。本优选实施例和第一优选实施例的区别在于该裸眼3D面板52为透镜式裸眼3D面板。
由于透镜式裸眼3D面板的具体工作原理与光栅式裸眼3D面板的具体工作原理类似，均能达到用户的左眼（或右眼）接收到左眼画面L（或右眼画面R），而不能接收到右眼画面R（或左眼画面L）的效果。因此本优选实施例的裸眼3D显示装置50的具体工作原理与上述的第一优选实施例中的相关描述相同或相似，具体请参见上述裸眼3D显示装置的第一优选实施例中的相关描述。
请参照图6，图6为本发明的裸眼3D显示装置的第四优选实施例的结构示意图。本优选实施例的裸眼3D显示装置60包括显示面板61、裸眼3D面板62、画面比较模块63以及散射模块64。本优选实施例和第二优选实施例的区别在于该裸眼3D面板62为透镜式裸眼3D面板。
由于透镜式裸眼3D面板的具体工作原理与光栅式裸眼3D面板的具体工作原理类似，均能达到用户的左眼（或右眼）接收到左眼画面L（或右眼画面R），而不能接收到右眼画面R（或左眼画面L）的效果。因此本优选实施例的裸眼3D显示装置60的具体工作原理与上述的第二优选实施例中的相关描述相同或相似，具体请参见上述裸眼3D显示装置的第二优选实施例中的相关描述。
请参照图7，图7为本发明的裸眼3D显示装置的第五优选实施例的结构示意图。本优选实施例的裸眼3D显示装置70包括显示面板71、裸眼3D面板72、画面比较模块73以及散射模块74。本优选实施例的裸眼3D显示装置70与第一优选实施例的裸眼3D显示装置30的区别在于，该裸眼3D显示装置70的显示面板71为多视点显示面板，在本优选实施例中为四视点电视面板。
该四视点显示面板可同时显示两个左眼画面以及两个右眼画面，这样用户可在不同的角度观看到相应的左眼画面以及右眼画面，从而更好的实现画面的3D效果。
这里设定四视点显示面板同时显示第一左眼画面L1、第二左眼画面L2、第一右眼画面R1以及第二右眼画面R2。其中第一左眼画面L1和第一右眼画面R1显示一视点的3D画面，第二左眼画面L2和第二右眼画面R2显示另一视点的3D画面。这样画面比较模块73包括对应第一左眼画面L1和第一右眼画面R1的多个画面比较区域以及对应第二左眼画面L2和第二右眼画面R2的多个画面比较区域。每个画面比较区域都对应散射模块74的一散射处理单元以及一电压施加单元。
画面比较模块73将第一左眼画面L1（或第二左眼画面L2）的灰阶与对应位置的第一右眼画面R1（或第二右眼画面R2）的灰阶进行比较，并产生比较结果。
散射模块74根据比较结果，对左眼画面（第一左眼画面L1或第二左眼画面L2）的出射光线以及右眼画面（第一右眼画面R1或第二右眼画面R2）的出射光线进行散射处理或不进行散射处理。
当然这里也可设置其他多视点显示面板，其工作原理与上述相似，这里不做详细阐述。
优选的，请参照图3A、图3B以及图3C，如电压施加单元343可以对施加在散射处理单元342上的控制电压进行调整，则散射单元34可以根据一画面比较区域311内的比较结果，确定电压施加单元343给相应的散射处理单元342施加的控制电压。
如某画面比较区域311内的左眼画面L的灰阶与对应位置的右眼画面R的灰阶的差值较大，则散射单元34通过电压施加单元343给相应散射处理单元342施加较大的控制电压，以减少散射处理单元342对该画面比较区域311出射的出射光线的散射处理，或散射处理单元342不对该画面比较区域311出射的出射光线进行散射处理。
如某画面比较区域311内的左眼画面L的灰阶与对应位置的右眼画面R的灰阶的差值较小，则散射单元34通过电压施加单元343给相应散射处理单元342施加较小的控制电压或不施加控制电压，以增大散射处理单元342对该画面比较区域311出射的出射光线的散射处理。
由于电压施加单元343的控制电压可以调整，因此对出射光线的散射处理更加灵活，可以更好的减少裸眼3D显示装置的摩尔纹现象以及画面串扰现象。
本发明的裸眼3D显示装置通过设置画面比较模块以及散射模块，对部分显示画面的出射光线进行散射处理，可以在不增大显示画面的串扰的基础上，减少裸眼3D显示装置的摩尔纹现象；解决了现有的裸眼3D显示装置的摩尔纹现象较为严重或显示画面的串扰较大的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
