Abstract

一种显示装置，采用黑白型的液晶显示面板（2），即在液晶显示面板（2）中不设置由色阻材料形成的彩色色阻层，并且在背光面板（1）与液晶层（23）之间设置有分光膜（3）。该分光膜（3）使背光面板（1）发出的光分为N种颜色的光，且每一种颜色的光投射至液晶显示面板（2）的对应的子像素上。这样，利用分光膜（3）代替现有液晶显示装置中的彩色色阻层，将背光面板（1）的白光分为不同颜色的光以实现彩色显示。由于分光膜（3）的分光效率一般可以超过30％，而彩色色阻层的分光效率一般在10％左右，因此，采用分光膜（3）可以降低显示装置的光损失，提高显示装置的光透过率，从而降低显示装置的功耗。

Description

显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示装置。
背景技术
随着显示技术的不断发展，有机电致发光显示面板(Organic Light Emitting Diode，OLED)、液晶显示面板(Liquid Crystal Display，LCD)、发光二极管(Light Emitting Diode，LED)显示面板及等离子显示面板(Plasma Display Panel，PDP)等平板显示面板发展迅速。
以现有的LCD为例，其主要由阵列基板、彩膜基板以及位于这两个基板之间的液晶分子组成。具体地，在阵列基板上设置有栅线、数据线、薄膜晶体管(TFT)以及像素电极。在彩膜基板上设置有黑矩阵、彩色色阻层以及公共电极。在栅线输入高电位的扫描信号时，与栅线连接的TFT处于开启状态。数据线加载的灰阶信号通过TFT施加到像素电极上，从而使像素电极与公共电极之间形成的电场控制液晶分子翻转。液晶分子对通过的背光源发出的光进行调制，使其以不同光强照射到彩膜基板的彩色色阻层上。彩色色阻层利用色阻滤光原理将白光分为红、绿、蓝三基色以实现彩色显示。由于彩色色阻层的色阻材料的光透过率较低，导致LCD的光损失较大，光透过率较低。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施例作进一步的详细描述。显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本发明保护的范围。
附图中各部件的形状和大小不反映显示装置的真实比例，目的只是示意说明本发明内容。
本发明实施例提供了一种显示装置。如图1a至图1d所示，该显示装置包括：发白光的背光面板1，位于背光面板1出光侧的黑白型的液晶显示面板2，以及位于液晶层23与背光面板1之间的分光膜3。液晶显示面板2包括相对设置的第一基板21与第二基板22，以及位于第一基板21与第二基板22之间的液晶层23。液晶显示面板2具有呈矩阵排列的多个像素。每一像素包括N个沿行方向排列的子像素，N为大于或等于3的整数。背光面板1发出的光经过分光膜3后分为N种颜色的光，且每一种颜色的光投射至液晶显示面板2的对应的子像素上。
需要说明的是，在本发明实施例提供的上述显示装置中，黑白型的液晶显示面板是指不设置由色阻材料形成的彩色色阻层的液晶显示面板。
本发明实施例提供的上述显示装置采用黑白型的液晶显示面板，即在液晶显示面板中不设置由色阻材料形成的彩色色阻层，并且在背光面板与液晶层之间设置有分光膜。该分光膜使背光面板发出的光分为N种颜色的光，且每一种颜色的光投射至液晶显示面板的对应的子像素上。这样，利用分光膜代替现有液晶显示装置中的彩色色阻层，将背光面板的白光分为不同颜色的光以实现彩色显示。由于分光膜的分光效率一般可以超过30％，而彩色色阻层的分光效率一般在10％左右，因此，采用分光膜可以降低显示装置的光损失，提高显示装置的光透过率，从而降低显示装置的功耗。
第一基板可以为阵列基板，第二基板可以为对置基板。当然第一基板也可以为对置基板，第二基板可以为阵列基板，在此不作限定。
根据一个实施例，N可以等于3。3种颜色的光可以分别为红色光、绿色光和蓝色光。
在具体实施时，如图2所示，分光膜3可以由若干呈周期分布的分光微结构31组成。分光微结构31例如可以为阶梯结构。当白光通过分光微结构31时，由于白光中不同波长的光通过该分光微结构31后的折射角不同，因此白光会分成不同颜色的光。每一颜色的光投射在液晶显示面板2中的对应的子像素20上，从而可以实现彩色显示。由于分光膜的具体结构和原理均与现有的分光膜的结构和原理相同，在此不作详述。
根据本发明的一个实施例，如图1a至图1d所示，第一基板21比第二基板22更靠近背光面板1。
如图1a至图1d所示，在第一基板21背向液晶层23的一侧以及在第二基板22背向液晶层23的一侧还可以设置有偏光片24。
如图1a所示，分光膜3可以位于背光面板1面向液晶显示面板2的一侧。
或者，如图1b所示，分光膜3可以位于第一基板21面向液晶层23的一侧。
或者，如图1c和图1d所示，分光膜3可以位于第一基板21面向背光面板1的一侧。
在第一基板21背向液晶层23的一侧还设置有偏光片24的情况下，如图1c所示，分光膜3可以位于偏光片24面向背光面板1的一侧。 或者，如图1d所示，分光膜3也可以位于第一基板21与偏光片24之间。
如图1a至图1d所示，液晶显示面板2与背光面板1例如可以通过封框胶4进行固定。
根据本发明的实施例，如图3所示，背光面板1可以为有机电致发光显示面板。有机电致发光显示面板具有呈矩阵排列的多个发光像素。至少一列相邻的发光像素对应的区域为列区域(图3中如附图标记11和12所示)。有机电致发光显示面板中发光列区域11与遮光列区域12交替排列。在进行显示时，发光列区域11中的发光像素发光，遮光列区域12中的发光像素不发光。
在液晶显示面板2中，至少一列像素对应的区域为单眼像素区域(图3中如附图标记01和02所示)。且左眼像素区域01与右眼像素区域02交替排列。在进行2D显示时，左眼像素区域01对应的像素与相邻的右眼像素区域02对应的像素显示相同的图像信息。在进行3D显示时，左眼像素区域01对应的像素显示左眼图像信息，右眼像素区域02对应的像素显示右眼图像信息。
有机电致发光显示面板中的发光列区域11发出的光经过液晶显示面板中的左眼像素区域01射向对应人左眼的方向，且经过液晶显示面板中的右眼像素区域02射向对应人右眼的方向。
在具体实施时，可以通过调整液晶显示面板与有机电致发光显示面板之间的距离，使有机电致发光显示面板中的发光列区域发出的光经过液晶显示面板中的左眼像素区域射向对应人左眼的方向，且经过液晶显示面板中的右眼像素区域射向对应人右眼的方向。具体原理与现有的3D显示装置的原理相同，在此不作详述。
在本发明实施例提供的显示装置中，有机电致发光显示面板控制显示的亮度，分光膜控制显示的色度，液晶显示面板通过控制液晶层中液晶分子的旋转控制有机电致发光显示面板的光经过分光膜和液晶层后出光的程度，即，液晶显示面板控制显示的灰度。通过控制有机电致发光显示面板的发光列区域以及控制液晶显示面板的显示内容，可以实现2D显示和3D显示的切换。但是在上述显示装置中，在进行3D显示时，只能在固定位置处才能看到较好的3D效果。只要人眼移动，就会出现串扰现象，从而使3D效果降低，甚至是没有3D效果。
因此，根据本发明的另一实施例，为了减轻或避免由于人眼移动导致的3D串扰问题，显示装置还可以包括人眼追踪控制模块。该人眼追踪控制模块配置为根据目标人眼的左右平移距离控制液晶显示面板的单眼像素区域沿行方向平移，或控制有机电致发光显示面板的列区域沿行方向平移。
下面通过两个具体的实施例分别进行说明。
实施例一、
人眼追踪控制模块配置为根据目标人眼的左右平移距离控制液晶显示面板的单眼像素区域沿行方向平移。
具体地，人眼追踪控制模块可以包括：

Figure PCTCN2016098496-appb-000005
确定液晶显示面板中单眼像素区域的计算平移距离ΔS，L为目标人眼与有机电致发光显示面板的距离，H为液晶显示面板的液晶层与有机电致发光显示面板的距离；以及
控制单元，配置为根据确定的计算平移距离ΔS，控制液晶显示面板的单眼像素区域沿与人眼移动方向一致的行方向平移整数个子像素的距离。即，当人眼向左平移时，液晶显示面板的单眼像素区域沿行方向向左平移。当人眼向右平移时，液晶显示面板的单眼像素区域沿行方向向右平移。
控制单元可以进一步配置为：根据确定的计算平移距离ΔS，按照
Figure PCTCN2016098496-appb-000006
计算平移倍数m，ΔX为液晶显示面板中一列子像素的宽度；
若平移倍数m为整数，则控制液晶显示面板的单眼像素区域沿行方向平移m个子像素的距离；
若平移倍数m不为整数，则将平移倍数m四舍五入后得到m′，并控制液晶显示面板的单眼像素区域沿行方向平移m′个子像素的距离。
以目标人眼向右平移为例进行说明。如图4所示，当目标人眼向右平移距离ΔP时，人眼向右平移距离ΔP与单眼像素区域(01和02)的计算平移距离ΔS满足公式
Figure PCTCN2016098496-appb-000007
因此，可以计算出单眼像素区域(01和02)的计算平移距离ΔS。由于液晶显示面板中的每一个单眼像素区域(01和02)是至少一列像素对应的区域，因此，当控制液晶显示面板中的单眼像素区域(01和02)平移时，只能是以子像素为最小单位进行平移。因此，当计算平移距离ΔS等于液晶显示面板中一列子 像素的宽度ΔX的整数倍时，即，
Figure PCTCN2016098496-appb-000008
中的平移倍数m为整数时，控制液晶显示面板的单眼像素区域(01和02)沿行方向向右平移m个子像素的距离，即平移ΔS。而当平移倍数m不为整数时，尽量使单眼像素区域(01和02)平移的距离既满足子像素宽度的整数倍，又与计算出的计算平移距离ΔS最接近。因此，先将平移倍数m四舍五入后得到m′，再控制液晶显示面板的单眼像素区域沿行方向向右平移m′个子像素的距离。例如，在图4中，液晶显示面板的单眼像素区域(01和02)向右平移了一个子像素的宽度。
实施例二、
人眼追踪控制模块配置为根据目标人眼的左右平移距离控制有机电致发光显示面板的列区域沿行方向平移。
例如，人眼追踪控制模块可以包括：
人眼追踪单元，配置为根据目标人眼向左或向右的平移距离ΔP，按照
Figure PCTCN2016098496-appb-000009
确定有机电致发光显示面板的列区域的计算平移距离ΔS′，L为目标人眼与有机电致发光显示面板的距离，H为液晶显示面板的液晶层与有机电致发光显示面板的距离；以及
控制单元，配置为根据确定的计算平移距离ΔS′，控制有机电致发光显示面板的列区域沿与人眼移动方向相反的行方向平移整数个发光像素的距离。即，当人眼向左平移时，有机电致发光显示面板的列区域沿行方向向右平移。当人眼向右平移时，有机电致发光显示面板的列区域沿行方向向左平移。
控制单元可以进一步配置为：根据确定的计算平移距离ΔS′，按照
Figure PCTCN2016098496-appb-000010
计算平移倍数m，ΔX′为有机电致发光显示面板中一列发光像素的宽度；
若平移倍数m为整数，则控制有机电致发光显示面板的列区域沿行方向平移m个发光像素的距离；
若平移倍数m不为整数，则将平移倍数m四舍五入后得到m′，并控制有机电致发光显示面板的列区域沿行方向平移m′个发光像素的距离。
以目标人眼向右平移为例进行说明。如图5所示，当目标人眼向右平移距离ΔP时，人眼向右平移距离ΔP与列区域(11和12)的计算平移距离ΔS′满足公式
Figure PCTCN2016098496-appb-000011
因此，可以计算出列区域(11和12) 的计算平移距离ΔS′。由于有机电致发光显示面板中的每一个列区域(11和12)是至少一列发光像素对应的区域，因此，当控制有机电致发光显示面板中的列区域(11和12)平移时，只能是以发光像素为最小单位进行平移。因此，当计算平移距离ΔS′等于有机电致发光显示面板中一列发光像素的宽度ΔX′的整数倍时，即，
Figure PCTCN2016098496-appb-000012
中的平移倍数m为整数时，控制有机电致发光显示面板中的列区域(11和12)沿行方向向左平移m个发光像素的距离，即平移ΔS′。而当平移倍数m不为整数时，尽量使列区域(11和12)平移的距离既满足发光像素宽度的整数倍，又与计算的计算平移距离ΔS′最接近。因此，先将平移倍数m四舍五入后得到m′，再控制有机电致发光显示面板中的列区域(11和12)沿行方向向左平移m′个发光像素的距离。
在具体实施时，人眼追踪控制模块中的人眼追踪单元可以设置在液晶显示面板的出光侧。当人眼追踪控制模块配置为根据目标人眼的左右平移距离控制液晶显示面板的单眼像素区域沿行方向平移时，控制单元可以集成在液晶显示面板中的驱动芯片上。当人眼追踪控制模块配置为根据目标人眼的左右平移距离控制有机电致发光显示面板的列区域沿行方向平移时，控制单元可以集成在有机电致发光显示面板中的驱动芯片上，在此不作限定。
本发明实施例提供的上述显示装置采用黑白型的液晶显示面板，即在液晶显示面板中不设置由色阻材料形成的彩色色阻层，并且在背光面板与液晶层之间设置有分光膜。该分光膜使背光面板发出的光分为N种颜色的光，且每一种颜色的光投射至液晶显示面板的对应的子像素上。这样，利用分光膜代替现有显示装置中的彩色色阻层，将背光面板的白光分为不同颜色的光以实现彩色显示。由于分光膜的分光效率一般可以超过30％，而彩色色阻层的分光效率一般在10％左右，因此，采用分光膜可以降低显示装置的光损失，提高显示装置的光透过率，从而降低显示装置的功耗。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
