附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例，而非对本发明的限制。
图1a为一种已知双视场显示器的局部结构示意图；

具体实施方式
图1a示出了一种已知的双视场显示器。显示面板10上贴合有光栅，例如能够提高双视图像精细度的狭缝光栅11。该狭缝光栅11是一种由交错排列的透明条纹和遮光条纹构成的光学器件。如图1b所示，狭缝光栅11的透明条纹对应透光区111，使得多个像素的一小部分能够露出，遮光条纹对应遮光区112，使得多个像素全部或部分被覆盖。这样一来，位于显示装置左侧左视区12的用户可以通过狭缝光栅11的透光区111看到显示面板10上 的一部分像素(包括多个第一显示区101)；位于显示装置右侧右视区13的用户可以通过狭缝光栅11的透光区111看到显示面板10上的另一部分像素(包括多个第二显示区102)。左视区12和右视区13之间的区域为串扰区14，该区域可以同时看到第一显示区101和第二显示区102的像素，因此显示的画面会产生串扰，所以串扰区13一般不作为用户的观测区。
然而，由于狭缝光栅11与像素所在的平面具有数百微米的距离，所以像素会在透光区111的部分区域产生漏光。例如，当用户位于左视区12时，应该在右视区13看到的第二显示区102的像素会透过透光区111的上下边缘将光线出射至左视区12，从而使得位于左视区12的用户看到的画面产生串扰。这样一来，即使用户位于左视区12或右视区13，当用户偏上或偏下观看显示面板10时，仍然会受到第二显示区102或第一显示区101像素出射光的影响。从而限制了用户的观看角度，降低了显示装置的显示效果和用户体验。
本发明实施例提供一种双视场显示器及其制造方法、驱动方法，解决了双视场显示器用户视角受限的问题。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本发明专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置 改变后，则该相对位置关系也可能相应地改变。
本发明实施例提供一种双视场显示器，如图2a所示，包括相对设置的彩膜基板20和阵列基板(图中未示出)，彩膜基板20或阵列基板的一侧设置有狭缝光栅11。如图2b所示，彩膜基板20包括多个像素单元201和围绕每个像素单元201的第一黑矩阵202。
如图2c所示，狭缝光栅11可以包括间隔设置，并呈矩阵形式排列的遮光区112和透光区111。
透光区111部分露出两个水平方向上相邻的像素单元201。
此外，如图2b所示，上述双视场显示器还可以包括用于防止透光区111的上边缘区域A和/或下边缘区域B漏光的阻光部300。
遮光区112可以部分覆盖至少两个水平方向上相邻的像素单元201，并完全覆盖对应遮光区112位置的第一黑矩阵202。当遮光区112覆盖的像素单元201的数量越多，光栅制作精度和难度越低，但是画面的精细度也会降低。因此，本领域技术人员可以综合考虑显示效果和生产成本对遮光区112的尺寸进行设计。本发明实施例是以遮光区112部分覆盖两个水平方向上相邻的像素单元201(图2a中覆盖水平方向相邻的两个像素单元201L和201R)为例进行的说明。
需要说明的是，第一，彩膜基板20或阵列基板的一侧设置有狭缝光栅11，可以是指，由于彩膜基板20和阵列基板对盒设置，因此，狭缝光栅11可以位于阵列基板靠近所述彩膜基板20的一侧表面；或者，位于彩膜基板20远离所述阵列基板的一侧表面，即位于由彩膜基板20和阵列基板构成的显示面板10的出光侧一侧的表面。本发明实施例以，狭缝光栅11位于显示面板10的出光侧一侧的表面为例进行说明，但对狭缝光栅11的设置位置不进行限定。
第二，遮光区112部分覆盖至少两个相邻的像素单元201，这里的部分覆盖，由图2c所示，可以是，遮光区112覆盖了两个相邻的像素单元201L和201R的大部分面积。而透光区111部分露出两个相邻的像素单元201，可以是，未被遮光区与112覆盖的小部分像素单元201裸露于透光区111，其中，遮光区112的面积大于透光区111的面积。这样一来，通过一个遮光区112分别对像素单元201L和201R进行遮挡，以使得位于显示面板左侧的用 户通过与上述遮光区112相邻的透光区111看到像素单元201L；位于右侧的用户通过上述透光区111看到像素单元201R，以实现双视场。
在此情况下，通过设置于透光区111的上边缘区域A和/或下边缘区域B漏光的阻光部300，当位于显示面板左侧用户偏上或偏下观看显示面板10时，该阻光部300可以阻挡像素单元201L的光线通过透光区111的上边缘区域A和/或下边缘区域B出射至人眼，而引起画面串扰，以保证用户能够清晰的看到像素单元201R。当用户位于显示面板右侧时同理可得。
本发明实施例提供一种双视场显示器，该双视场显示器包括相对设置的彩膜基板和阵列基板，彩膜基板或阵列基板的一侧设置有狭缝光栅，彩膜基板包括多个像素单元和围绕每个像素单元的第一黑矩阵。狭缝光栅包括间隔设置，并呈矩阵形式排列的遮光区和透光区。其中，透光区部分露出两个相邻的像素单元；该双视场显示器还包括用于防止透光区的上边缘和/或下边缘区域漏光的阻光部。这样一来，通过上述阻光部，有效地阻止了光线从狭缝光栅透光区的上边缘或下边缘区域出射至人眼。从而提高了用户在左视区或右视区的观看视角，避免了由于偏上或偏下观看画面时，产生串扰现象。
在一个示例中，上述阻光部300包括位于彩膜基板上，对应透光区111的上边缘区域A和/或下边缘区域B的第二黑矩阵301。
例如，上述第二黑矩阵301的宽度W’大于等于透光区111的宽度W。这样一来，可以保证第二黑矩阵301与透光区111在宽度方向，即图2b中的水平方向上无间隙，从而有效防止像素单元201的光线从透光区111的上边缘区域A或下边缘区域B出射至人眼，导致漏光现象的出现而引起图像的串扰。
在一个示例中，如图3b所示，第二黑矩阵301的形状为梯形，该梯形的短底边位于透光区111内。这样一来，采用梯形的第二黑矩阵301能够在防止漏光的同时，避免由于设置第二黑矩阵301，而导致与第二黑矩阵301相接触的亚像素的面积大大减小，从而降低了显示装置的开口率。
在一个示例中，第一黑矩阵202与第二黑矩阵301为一体结构。这样一来，能够在制作第一黑矩阵202的同时完成第二黑矩阵301的制作，从而简化制作工艺。
需要说明的是，像素单元201可以包括相互平行排列的至少一个红色亚 像素2010、一个绿色亚像素2011以及一个蓝色亚像素2012。本发明对各个亚像素的排列顺序并不进行限制。如图2a-2c所示，狭缝光栅11的遮光区112覆盖了两个相邻的像素单元201，而该像素单元201只包括了依次排列的红色亚像素2010、绿色亚像素2011以及蓝色亚像素2012。因此，每个遮光区112覆盖的像素单元201均相同，这样一来，对于整个显示面板而言，对应透光区111的上边缘区域A和下边缘区域B的亚像素的颜色是固定的，例如对应透光区111的上边缘区域A的亚像素为红色亚像素2010，对应透光区111的下边缘区域B的亚像素为蓝色亚像素2012。在实际生产加工过程中，由于制作工艺以及制作精度等因素的影响，阻光部300不可能100％的将从透光区111的上边缘区域A和下边缘区域B出射的光线完全遮挡。这样未经过阻光部300完全遮挡的光线出射至人眼后，使得每一个透光区111的上边缘区域A发出红色的光，每一个透光区111的下边缘区域B发出蓝色的光，从而可能导致整个显示面板出现固定颜色的串扰。
为了进一步避免出现上述串扰现象，本发明实施例中的像素单元201可以至少包括四个亚像素，其中至少两个亚像素的颜色相同。例如，如图3b所示，像素单元201包括依次排列的一个红色亚像素2010、一个绿色亚像素2011、一个蓝色亚像素2012以及又一个红色亚像素2010。像素单元201下边缘的像素单元201’包括依次排列的一个绿色亚像素2011、一个蓝色亚像素2012、一个红色亚像素2010以及又一个绿色亚像素2011。其它像素单元201在此不再一一举例。这样一来，可以避免因每一个像素单元201内的亚像素的数量和顺序均相同导致整个显示面板出现固定颜色的串扰。
以下对像素单元201至少包括四个亚像素，其中至少两个亚像素的颜色相同的情况进行举例说明。
实施例一
如图3a所示，狭缝光栅11的遮光区112部分覆盖两个相邻的像素单元201L和201R，并完全覆盖对应上述遮光区112的第一黑矩阵202。如图3b所示，每个像素单元201包括四个亚像素，从而避免因每一个像素单元201内的亚像素的数量和顺序均相同而导致整个显示面板出现固定颜色的串扰。
透光区111部分露出两个相邻的像素单元201，并完全露出对应上述透光区111的第一黑矩阵202。
透光区111的上边缘区域A和下边缘区域B设置有呈梯形状的，用于防止透光区111的上边缘区域A和下边缘区域B漏光的第二黑矩阵301。该第二黑矩阵301的长底边大于等于透光区111的宽度L2，并且第二黑矩阵301与第一黑矩阵202为一体结构。
在本实施例中，通过一个遮光区112分别对像素单元201L和201R进行遮挡，以使得位于显示面板左侧的用户通过与上述遮光区112相邻的透光区111看到像素单元201L；位于右侧的用户通过上述透光区111看到像素单元201R。在此基础上，通过设置第二黑矩阵301，可以对像素单元201从透光区111的上边缘区域A和下边缘区域B漏出的光线进行吸收。这样一来，当用户的视角微幅度在相对于水平面5度以内偏上或偏下观看时，可以，降低双视场显示器的画面串扰。
实施例二
本实施例与实施例一的不同之处在于，每个像素单元201所包括的四个亚像素之一为用于显示黑色画面的暗态亚像素2013，如图4b所示，以满足用户对视角微幅度进一步调高的要求。
上述暗态亚像素2013可以包括红色亚像素2010，或绿色亚像素2011，或蓝色亚像素2012。
上述阻光部300可以包括暗态亚像素2013对应透光区111的上边缘区域A和/或下边缘区域B的部分。这样一来，在设置有上述第二黑矩阵301的基础上，还可以通过由显示黑色画面的暗态亚像素2013构成上述阻光部300，从而使得用户的视角微幅度进一步增大时，能够防止透光区111的上边缘区域A和/或下边缘区域B的部分漏光，而引起画面的串扰。
需要说明的是，暗态亚像素2013可以包括上述红色亚像素2010，或上述绿色亚像素2011，或上述蓝色亚像素2012。例如，当像素单元201中红色亚像素2010、绿色亚像素2011、蓝色亚像素2012之一显示黑色画面时，该亚像素构成上述暗态亚像素2013。例如，如图4b所示，像素单元201包括依次排列的一个红色亚像素2010，一个绿色亚像素2011、一个蓝色亚像素2012以及一个暗态亚像素2013，其中暗态亚像素2013由红色亚像素2010构成。当双视场显示器接收到用于显示黑色画面的控制信号时，位于该像素单元201中最后一行的红色亚像素2010位置处的液晶发生偏转，使得无光线 透过上述红色亚像素2010，这时显示面板对应该红色亚像素2010的位置显示黑色画面，因此该位置处的红色亚像素2010构成暗态亚像素2013。
同理，像素单元201下边缘的像素单元201’包括依次排列的绿色亚像素2011、蓝色亚像素2012、红色亚像素2010以及由绿色亚像素2011构成的暗态亚像素2013。其它位置的像素单元与此相似。
由于每个像素单元201中不同亚像素的排列顺序并不固定，因此可以避免因每一个像素单元201内的亚像素的数量和顺序均相同而导致整个显示面板出现固定颜色的串扰。
在本实施例中，通过一个遮光区112分别对像素单元201L和201R进行遮挡，以使得位于显示面板左侧的用户通过与上述遮光区112相邻的透光区111看到像素单元201L；位于右侧的用户通过上述透光区111看到像素单元201R。在此基础上，通过设置第二黑矩阵301，可以对像素单元201从透光区111的上边缘区域A和下边缘区域B漏出的光线进行吸收。另外，通过设置位于每个像素单元201中用于显示黑色画面的暗态亚像素2013，可以减小从透光区111的上边缘区域A和下边缘区域B漏出的光线。
这样一来，在设置用于吸收漏光的第二黑矩阵301的基础上，通过改变狭缝光栅11的透光区111和遮光区112的尺寸，并在像素单元201中设置暗态亚像素2013，可以使用户的视角微幅度在20度以内偏上或偏下观看时，显示画面不会发生串扰。从而提高了用户的视角微幅度。此外，由于每个像素单元201包括四个亚像素，其中一个亚像素为显示黑色画面的暗态亚像素2013，因此该双视场显示器在垂直方向上的分辨率降低为3/4。在保证较高的视角微幅度的前提下，进一步地可以提高双视场显示器在垂直方向上的分辨率。
实施例三
本实施例与实施例二的不同之处在于，每个像素单元201包括五个亚像素，其中一个亚像素为用于显示黑色画面的暗态亚像素2013，如图5a所示。
像素单元201包括依次排列的一个红色亚像素2010，一个绿色亚像素2011、一个蓝色亚像素2012、一个红色亚像素2010以及一个暗态亚像素2013。例如，位于该像素单元201中最后一行的暗态亚像素2013由绿色亚像素2011构成，当双视场显示器接收到用于显示黑色画面的控制信号时，位于该像素 单元201中最后一行的绿色亚像素2011位置处的液晶发生偏转，使得无光线透过上述绿色亚像素2011，这时显示面板对应该绿色亚像素2011的位置显示黑色画面。而该位置处的绿色亚像素2010构成暗态亚像素2013。
同理，像素单元201下边缘的像素单元201’包括依次排列的一个蓝色亚像素2012、一个红色亚像素2010、一个绿色亚像素2011、一个蓝色亚像素2012以及一个由红色亚像素2010构成的暗态亚像素2013。其它位置的像素单元与此相似。
在本实施例中，通过一个遮光区112分别对像素单元201L和201R进行遮挡，以使得位于显示面板左侧的用户通过与上述遮光区112相邻的透光区111看到像素单元201L；位于右侧的用户通过上述透光区111看到像素单元201R。在此基础上，通过设置第二黑矩阵301可以对像素单元201从透光区111的上边缘区域A和下边缘区域B漏出的光线进行吸收。另外，通过设置位于每个像素单元201中用于显示黑色画面的暗态亚像素2013，可以减小从透光区111的上边缘区域A和下边缘区域B漏出的光线。
这样一来，在设置用于吸收漏光的第二黑矩阵301的基础上，通过改变狭缝光栅11的透光区111和遮光区112的尺寸(由于遮光区112覆盖的像素单元201包括五个亚像素，因此该遮光区111的长度增加)，并在像素单元201中设置暗态亚像素2013，可以使用户的视角微幅度在20度以内偏上或偏下观看时，显示画面不会发生串扰。从而提高了用户的视角微幅度。此外，由于每个像素单元201包括五个亚像素，其中一个亚像素为显示黑色画面的暗态亚像素2013，因此该双视场显示器在垂直方向上的分辨率降低为4/5。因此该实施例三提供的方案的分辨率高于实施例二提供的方案。此外，实施例三中，透光区111的长度L较实施例二大，因此显示图案没有实施例二的精细。
当然，上述仅仅是对200PPI(Pixels per inch，每英寸所拥有的像素)的双视场显示装置中，狭缝光栅11结构以及暗态亚像素2013设置的举例说明。本领域技术人员，可以根据实际显示器性能的需要，综合考虑分辨率、抗串扰程度以及画面精细程度等因素，对狭缝光栅11结构以及暗态亚像素2013的数量进行设置。例如对于更高PPI(400PPI)的显示装置，可以增大每个像素单元201中的亚像素的数量，包括增加暗态亚像素2013的数量。以达到 降低画面串扰目的。其它设置方案在此不再一一举例，但都应当属于本发明的保护范围。
采用上述方案降低或消除画面串扰，例如在像素单元201中设置用于显示黑色画面的暗态亚像素2013时，需要增大遮光区112的面积以对暗态亚像素2013进行覆盖。因此，本发明实施例中，在制作狭缝光栅11时，透光区111的长度L可以小于等于竖直方向上两个相邻透光区111中心间距S的一半，如图5a所示。
本发明实施例还提供一种双视场显示器的制造方法，包括：
S101、提供阵列基板和彩膜基板，其中彩膜基板包括多个像素单元201和围绕每个像素单元的第一黑矩阵202；
S102、制作狭缝光栅11，其中该狭缝光栅11包括间隔设置并呈矩阵形式排列的遮光区112和透光区111；
S103、制作用于防止透光区111的上边缘区域A和/或下边缘区域B漏光的阻光部300；以及
S104、对盒彩膜基板和阵列基板，并且将狭缝光栅11设置于彩膜基板或阵列基板的一侧，使得透光区111部分露出两个水平方向上相邻的像素单元201。
需要说明的是，上述步骤S104中，将狭缝光栅11设置于彩膜基板或阵列基板的一侧是指，狭缝光栅11位于阵列基板靠近所述彩膜基板20的一侧表面；或者，位于彩膜基板20远离所述阵列基板的一侧表面，即位于由彩膜基板20和阵列基板构成的显示面板10的出光侧一侧的表面。
通过形成阻光部，有效地阻止了光线从狭缝光栅透光区的上边缘或下边缘区域出射至人眼。从而提高了用户在左视区或右视区的观看视角，避免了由于偏上或偏下观看画面时，产生串扰现象。
在一个示例中，上述步骤S103包括：
在彩膜基板上，对应透光区111的上边缘区域A和/或下边缘区域B的位置制作第二黑矩阵301。
例如，第二黑矩阵301的宽度W’大于等于透光区111的宽度W2。这样一来，可以保证第二黑矩阵301与透光区111在宽度方向，即图2b中的水平方向上无间隙，从而有效防止像素单元201的光线从透光区111的上边缘 区域A或下边缘区域B出射至人眼，导致漏光现象的出现而引起图像的串扰。
在一个示例中，上述在彩膜基板上，对应透光区111的上边缘区域A和/或下边缘区域B的位置制作第二黑矩阵301包括：
在第一黑矩阵202的上边缘区域A和/或下边缘区域B制作呈梯形状的第二黑矩阵301。其中，上述梯形的短底边位于透光区111内。这样一来，采用梯形的第二黑矩阵301能够在防止漏光的同时，避免由于设置第二黑矩阵301，而导致与第二黑矩阵301相接触的亚像素的面积大大减小，从而降低了显示装置的开口率。
在一个示例中，第一黑矩阵202与第二黑矩阵301可以为一体结构。这样一来，能够在制作第一黑矩阵202的同时完成第二黑矩阵301的制作，从而简化制作工艺。
在一个示例中，采用上述方案降低或消除画面串扰，例如在像素单元201中设置用于显示黑色画面的暗态亚像素2013时，需要增大遮光区112的面积以对暗态亚像素2013进行覆盖。因此，上述步骤S102可以包括：
在制作狭缝光栅11时，透光区111的长度L可以小于等于竖直方向上两个相邻透光区111中心间距S的一半，如图5a所示。
在一个示例中，上述步骤S102可以包括：遮光区112可以部分覆盖至少两个水平方向上相邻的像素单元201，并完全覆盖对应遮光区112位置的第一黑矩阵202。当遮光区与112覆盖的像素单元201的数量越多，光栅制作精度和难度越低，但是画面的精细度也会降低。因此，本领域技术人员可以综合考虑显示效果和生产成本对遮光区112的尺寸进行设计。本发明实施例是以遮光区112部分覆盖两个水平方向上相邻的像素单元201(图2a中覆盖水平方向相邻的两个像素单元201L和201R)为例进行的说明。
本发明实施例还提供一种双视场显示器的驱动方法(即向如上所述的实施例二或三双视场显示器的阵列基板输入显示信号以进行显示的方法)，在像素单元201包括暗态亚像素2013的情况下，上述方法包括：
S201、向阵列基板输入控制信号。
S202、阵列基板根据所述控制信号，控制暗态亚像素2013对应位置处的液晶进行偏转，使得双视场显示器对应暗态亚像素2013的位置显示上述黑色画面。
例如，暗态亚像素2013对应位置处的液晶偏转至一定角度，并遮挡该显示器背光源从该位置出射的光线时，双视场显示器的显示面板上对应暗态亚像素2013的位置显示黑色画面。
在本实施例中，暗态亚像素对应狭缝光栅透光区的上边缘和/或下边缘的部分可以构成阻光部。通过上述阻光部，有效地阻止了光线从狭缝光栅透光区的上边缘或下边缘区域出射至人眼。从而提高了用户在左视区或右视区的观看视角，避免了由于偏上或偏下观看画面时，产生串扰现象。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
