Description

液晶显示装置 技术领域
本申请涉及液晶显像设备技术领域，尤其涉及液晶显示装置及其视角色差改善方法。
背景技术
目前，大尺寸液晶显示面板大多采用负型VA(Vertical Alignment，垂直配向)液晶技术或IPS(In-Plane Switching，平面转换)液晶技术进行制造。VA液晶技术与IPS液晶技术相比具有生产效率高、制造成本低的优势，但在光学性质上，VA液晶技术与IPS液晶技术相比存在较明显的光学性质缺陷。然而，在商业应用方面，大尺寸液晶面板尤其需要较大的视角呈现，由于VA液晶技术的液晶显示面板存在视角色差的问题，其往往无法符合市场应用需求。
一般地，VA液晶技术是通过将影像像素组的各子像素再划分为主像素和次像素，藉由空间上向主像素和次像素给予不同的驱动电压来解决视角色差的缺陷。然而，该种像素设计往往需要再设计金属走线或TFT(Thin Film Transistor，薄膜晶体管)组件来驱动次像素，导致可透光开口区牺牲，这样不仅影响了液晶显示面板穿透率，还增加了背光模组的制作成本。

如图1至图3所示，本申请实施例提供的液晶显示装置，包括：背光模组10；液晶显示面板20，所述液晶显示面板20与所述背光模组10层叠设置，所述液晶显示面板20上设有阵列排布的多组影像像素组21，所述影像像素组21包括多个影像像素；液晶调光面板30，所述液晶调光面板30与所述液晶显示面板20层叠设置，且所述液晶显示面板20位于所述背光模组10与所述液晶调光面板30之间，并通过控制所述液晶调光面板30相对于不同组的所述影像像素组21的位置的驱动电压以实现控制所述液晶调光面板30中的液晶分子间进行视角光能量调适。
本实施例中，液晶显示面板20可以为VA(Vertical Alignment，垂直配向)型液晶显示面板20、TN(Twisted Nematic，扭曲向列型)型液晶显示面板20、OCB(Optically Compensated Birefringence，光学补偿弯曲排列)型液晶显示面板20、曲面显示面板、COA型液晶显示面板，也可以为不使用补偿膜偏光片的VA型液晶显示面板20、不使用补偿膜偏光片的TN型液晶显示面板20或不使用补偿膜偏光片的OCB型液晶显示面板20。在实际应用时，可以选择其中之一作为液晶显示装置的液晶显示面板20。当然，在本申请其他实施例中，也可以选择其他类型的液晶面板作为液晶显示装置的液晶显示面板20，在此不作唯一限定。
如图1至图3所示，本实施例中，液晶显示面板20上阵列排布的多组影像像素组21可以是RGB(Red，红色；Green，绿色；Blue，蓝色)影像像素组21、WRGB(White，白色；Red，红色；Green，绿色；Blue，蓝色)影像像素组21或RGBY(Red，红色；Green，绿色；Blue，蓝色；Yellow，黄色)影像像素组21，当然，该影像像素组21也可以是其他颜色的影像像素的组合，不限于此。其中，RGB影像像素组21包括红色影像像素211、绿色影像像素212以及蓝色影像像素213，同理，WRGB影像像素组21包括白色影像像素、红色影像像素211、绿色影像像素212以及蓝色影像像素213，RGBY影像像素组21包括红色影像像素211、绿色影像像素212、蓝色影像像素213以及黄色影像像素。此外，本实施例中，液晶显示面板20中液晶的灌注工艺与现有技术中的液晶的灌注工艺相同。
在使用过程中，背光模组10用于提供照射液晶显示面板20的背光，通过控制液晶显示面板20中不同影像像素组21的位置的驱动电压以改变液晶显示面板20中液晶分子的排列状态，从而实现液晶显示面板20成像的目的。而本实施例中，由于在液晶显示面板20上方还层叠设置有液晶调光面板30，因此，可以通过控制液晶调光面板30相对于不同组的影像像素组21的位置的驱动电压，改变液晶调光面板30中液晶分子的排列状态，使得液晶调光面板30中的液晶分子间进行视角光能量调适，从而达到全视角颜色均一的效果，改善了采用VA液晶技术的液晶显示装置视角色差的问题，满足市场应用需求。
如图1至图2所示，进一步地，所述液晶调光面板30上设有多个调光像素31，所述驱动电压 为所述液晶调光面板30上的各所述调光像素31的驱动电压。其中，该液晶调光面板30上的各调光像素31均可单独驱动，并且通过控制各调光像素31的驱动电压，能够使得液晶显示装置显示的图像可以根据不同的视角范围进行精确的调适，达到全视角颜色均一的效果，提升用户体验。
本实施例中，液晶调光面板30为PDLC(Polymer Dispersed Liquid Crystal，聚合物分散液晶)阵列液晶面板。其中，PDLC(聚合物分散液晶)是将LC(liquid crystal，低分子液晶)与预聚物Kuer UV65胶相混合，在一定条件下经聚合反应，形成微米级的液晶微滴352均匀地分散在高分子聚合物351网络中，再利用液晶分子的介电各向异性获得具有电光响应特性的材料，它主要工作在散射态和透明态之间并具有一定的灰度。
如图4所示，当PDLC阵列液晶面板的电源37的开关36导通时，位于PDLC阵列液晶面板中的液晶微滴352的光轴垂直于透光导电薄膜表面排列，与电场方向一致。此时，液晶微滴352的寻常光折射率与聚合物351的折射率基本匹配，二者之间无明显接口，聚合物分散液晶层35为一基本均匀的介质，入射光经玻璃板33、夹层34以及透光导电膜32之后到达聚合物分散液晶层35，然后再经对侧的透光导电膜32、透光导电膜32以及玻璃板33射出，其中，入射光在聚合物分散液晶层35中不会发生散射，其出射光线垂直于玻璃板33射出，因此，聚合物分散液晶层35呈透明状态。这样，观众能够从液晶显示装置的正面观看到色彩绚丽的画面。
如图5所示，当PDLC阵列液晶面板的电源37的开关36关闭或者控制PDLC阵列液晶面板的驱动电压大小变化时，位于PDLC阵列液晶面板中的液晶微滴352的光轴取向随机，呈现无序状态。此时，液晶微滴352的有效折射率与聚合物351的折射率不匹配，聚合物分散液晶层35中不能形成有规律的电场，入射光被强烈散射，入射光经玻璃板33、夹层34以及透光导电膜32之后在聚合物分散液晶层35中多方向反射、折射传播，然后再经对侧的透光导电膜32、透光导电膜32以及玻璃板33从多个方向不规则的射出，因此，聚合物分散液晶层35呈不透明状态或半透明状态。此时，液晶显示面板20可以根据观众的不同位置进行视角光能量调适，使得液晶显示面板20的正视角能量向大视角分配，从而保证观众所在的位置能呈现出与正面视角同样的画面色彩和画面质量。
如图1所示，进一步地，每个所述调光像素31与所述液晶显示面板20上的每一所述影像像素组21一一对应设置。如此设计，可以有效地减少液晶调光面板30的分辨率，同时可以减少液晶调光面板30上的驱动线路以及驱动组件的数目，增加该液晶调光面板30的透光率。当然，每个调光像素31也可以与液晶显示面板20上的相邻的若干个所述影像像素组21对应设置。需要进一步说明的是：该种像素设计适用于调光像素31局部区域的面积足够大，以至于人眼无法识别不同局部区域间的色度不均匀性的情形。
如图2所示，进一步地，每个所述调光像素31与所述影像像素组21中的每一所述影像像素一一对应设置。此时，液晶调光面板30中与液晶显示面板20上的每一影像像素一一对应设置的调光像素31均可独立控制驱动，以适当的补偿液晶显示面板20上不同颜色区块位置处的颜色呈现，而液晶显示面板20上不同颜色区块位置亦可以有特别加强局部色相呈现的功能，以强调高饱和色相的呈现。
如图3所示，进一步地，所述液晶调光面板30的两相对表面均设有透光导电膜32，并通过所述透光导电膜32的布线以控制所述液晶调光面板30中相对于不同组的所述影像像素组21的位置的驱动电压以实现控制所述液晶调光面板30中的液晶分子间进行视角光能量调适。其中，透光导电膜32可以为Ag、Pt、Cu或Rh等金属透光导电膜32，或者In、Sn、Zn和Cd的氧化物及其复合多元氧化物透光导电薄膜。优选地，该透光导电薄膜为ITO(Indium Tin Oxides，氧化铟锡)透光导电薄，ITO透光导电薄具有优良的透光率和导电性能。
如图1至图3所示，进一步地，所述背光模组10为所述液晶显示面板20提供背光，所述背光为照射所述液晶显示面板20的准直光。优选地，本实施例中，液晶显示装置的1/3亮度视角小于10°。例如液晶显示装置的1/3亮度视角可以为2°、4°、6°、8°等。如此设计，可以确保背光模组10发出的光透过液晶显示面板20后仍能维持正向光能量，使得光能量分布得到有效合理的分配，达到节能省电的目的。其中，1/3亮度视角是指在屏幕中心的亮度减小到最大亮度的1/3的时候的水平或者垂直方向的视角。
本实施例中，背光模组10中可以包括一个或多个的发光点。优选地，背光模组10包括多个发光点时，所述多个发光点与液晶显示面板20中每一影像像素一一对应设置，使得该背光模组10中各个发光点所照射出的准直光能够集中照射到液晶显示面板20中相应的影像像素上，使得从液晶显示面板20中出射的光能够维持正向光能量，提升光效率，从而达到有效运用光能量的目的。
具体地，背光模组10的发光点可以为灯泡、发光二极管、冷阴极荧光管、热阴极荧光管、电致发光片、有机电致发光片以及扁平荧光灯等。当然，本申请的其他实施例也可选择其他类型的发光光源作为背光模组10的发光点，在此不作唯一限定。此外，本实施例中，背光模组10的每一发光点处还可以设置相应的聚光组件。该聚光组件可以是聚光透镜，或者用于聚光的光学膜片等。这种情形下，背光模组10的发光点可选为一般的散射光的发光光源，该发光光源发出的散射光经聚光组件会聚后形成准直光，然后再照射到液晶显示面板20上。
进一步地，所述液晶显示装置还包括用于调制解调所述液晶显示装置接收的画面信号的信号调制解调器(图未示)以及与所述信号调制解调器电性连接的控制器(图未示)，所述控制器根据所述信号调制解调器调制调解的信号以控制所述液晶显示面板20的所述影像像素的驱动电压以及所 述液晶调光面板30的所述调光像素31的驱动电压。当液晶显示装置接收到画面信号后，通过信号调制解调器对该画面信号进行调制解调，然后经调制解调后的信号再传递到控制器中，控制器根据该信号控制液晶显示面板20的显像，同时也控制液晶调光面板30对不同视角范围观看的画面颜色调适，从而消除液晶显示装置视角色差的问题，使得观看者在不同视角位置均能够获得与正视角度相同的画面效果。
进一步地，所述液晶显示装置还包括与所述控制器电性连接且用于跟踪并判定观看者眼睛相对于所述液晶显示装置位置的人眼跟踪装置(图未示)。当观看者相对于液晶显示装置的位置改变时，人眼跟踪装置能够立即捕捉观看者的移动行为并检测观看者相对于液晶显示装置的新的位置信息。然后，人眼跟踪装置再将检测到的观看者相对于液晶显示装置的新的位置信息传递给控制器，由控制器根据该位置信息控制液晶调光面板30的驱动电压，适时调整液晶调光面板30中聚合物351液晶散射和透光程度的比例，不同的视角位置给予不同程度的光能量补偿量，改善观看者位置改变后的显像画质，从而达到所有的视角位置均无色差的显示效果。
进一步地，所述人眼跟踪装置为CCD测位装置。CCD(Charge Coupled Device，电荷耦合组件)，又称为图像控制器或者CCD图像传感器。其中，CCD测位装置具有分辨率高，灵敏度高，动态范围广，影像失真程度低以及感光面积大等优点。当然，根据实际情况和需求，在本申请的其他实施例中，人眼跟踪装置也可以为其他任何可以实现跟踪定位功能的设备，在此不作唯一限定。
本申请实施例还提供一种液晶显示装置视角色差改善方法，包括以下步骤：
提供背光模组10、液晶显示面板20以及液晶调光面板30；
通过所述背光模组10向所述液晶显示面板20中的影像像素组21进行背光照射；
将所述液晶调光面板30设置于所述液晶显示面板20上，并通过控制所述液晶调光面板30相对于不同组的所述影像像素组21的位置的驱动电压以实现控制所述液晶调光面板30中的液晶分子间进行视角光能量调适。
本申请实施例提供的液晶显示装置视角色差改善方法由于在液晶显示面板20上叠层设置有液晶调光面板30，通过控制液晶调光面板30相对于不同组的所述影像像素组21的位置的驱动电压，改变液晶调光面板30中液晶分子的排列状态，以使所述液晶调光面板30中的液晶分子间进行视角光能量调适，从而达到全视角颜色均一的效果，改善了采用VA液晶技术的液晶显示装置视角色差的问题，满足市场需求。
需要进一步说明的是：图1至图5中箭头所指的方向为光线照射的方向。
如图6所示，本申请实施例提供的液晶显示装置可包括：背光模组10；液晶显示面板20，设置于所述背光模组上，其中所述液晶显示面板包括多个阵列排布的影像像素；液晶调光面板30， 设置于所述液晶显示面板上，其中所述液晶调光面板具有一透明状态及一散射状态，在所述透明状态中所述液晶调光面板允许所述影像像素的影像被直接正面观看，在所述散射状态中所述液晶调光面板允许所述影像像素所发出的光线被折射调整。其中，所述背光模组10所发出的光线是直射至所述液晶显示面板的影像像素，所述背光模组所发出的光线及所述影像像素之间的角度偏差是等于或小于10度。其中，所述液晶调光面板具有至少二个调光区域301、302，所述至少二个调光区域301、302是对位于所述液晶显示面板20的两侧，用以调整所述影像像素所发出的光线，以改善大视角观看时的色偏问题。
综上所述可知本申请乃具有以上所述的优良特性，得以令其在使用上，增进以往技术中所未有的效能而具有实用性，成为一极具实用价值的产品。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的思想和原则之内所作的任何修改、等同替换或改进等，均应包含在本申请的保护范围之内。
