Description

显示面板、其制作方法和显示装置 技术领域
本发明的实施例一种显示面板、其制作方法和显示装置。
背景技术
常用的被动偏光式3D显示装置，如图1中所示包括：顺次设置的背光单元1、第一偏光片2、阵列基板3、彩膜基板4、第二偏光片5和图案位相差膜片(Patterned Retarder Film)6。彩膜基板4的朝向阵列基板3的一侧(膜面上)设置有黑矩阵，黑矩阵包括多条矩阵条41。其中，矩阵条的宽度为h，彩膜基板的厚度与第二偏光片的厚度的总和为D。图1中角A是彩膜基板4的膜面上相邻矩阵条41之间的一个像素区的最大正确透光角度，角B是该3D显示装置的垂直视角，也是角A发生折射后的角度。因此，根据折射定律可知该垂直视角的一半B/2＝arc sin(折射率×sin(A/2))，其中，角A＝2arc tan(h/2D)、折射率为一定值，一般可取值为1.5。
在垂直视角B范围之内，用户可以看到较理想的三维图像；在垂直视角B之外，由于左右眼睛中的图像会发生串扰从而得到的三维图像效果较差。如果是一般的显示器，则用户的可视角度较小，从而得到的图像质量会下降。为了扩大垂直视角的范围，现有技术中通常采用在彩膜基板的与阵列基板相反的一侧且与黑矩阵对应的位置处设置遮光条或者在第二偏光片与图案位相差膜片之间与黑矩阵对应的位置处设置遮光条。但是，这样会使显示装置的开口率下降，导致显示器的亮度降低，从而使得用户看到的图像效果较差。
发明内容
本发明的实施例提供一种显示面板、其制作方法和显示装置，在增加显示器的可视角度的同时保证了较高的开口率，而且提高了显示器的亮度以及图像质量。
一方面，本发明的实施例提供一种显示面板，包括：阵列基板；彩膜基板，与所述阵列基板对盒且包括黑矩阵；多个遮光条，设置在所述彩膜基板 的远离所述阵列基板的一侧；电极，夹着所述多个遮光条设置，其中所述黑矩阵包括多个矩阵条，所述多个遮光条的每个对应于所述黑矩阵的矩阵条之一，所述遮光条的材料为聚合物分散液晶材料或者电致变色材料。
另一方面，本发明的实施例提供一种显示面板的制作方法，包括：形成阵列基板和彩膜基板；将所述阵列基板与所述彩膜基板对盒；在所述彩膜基板的远离所述阵列基板的一侧并与所述彩膜基板的黑矩阵中的矩阵条相对应的位置处形成电极和遮光条，使得所述电极夹着所述遮光条，其中，所述遮光条的材料为聚合物分散液晶材料或者电致变色材料。
再一方面，本发明的实施例提供一种显示装置，包括如上所述的显示面板。
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1为一种显示面板的示例性结构图；
图2为本发明的实施例提供的一种显示面板的结构示意图；
图3为本发明的实施例提供的另一种显示面板的结构示意图；
图4为本发明的实施例提供的又一种显示面板的结构示意图；以及
图5为本发明的另一实施例提供的一种显示面板的结构示意图。
具体实施方式
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。
本发明的实施例提供一种显示面板，参照图2所示，该显示面板包括：阵列基板3和彩膜基板4，彩膜基板4中包括黑矩阵，该黑矩阵包括多个矩阵条41，该显示面板还包括：遮光条7以及夹着遮光条7设置的电极10(图 1中未示出)，其中：
遮光条7设置在彩膜基板4的远离阵列基板3的一侧，并与黑矩阵中的矩阵条41相对应。
其中，遮光条7的材料可以为聚合物分散液晶(Polymer Dispersed Liquid Crystal，简称PDLC)材料或者电致变色材料。
PDLC材料和电致变色材料能够根据施加在其上的电压的变化而呈现透光和不透光状态。本实施例中的遮光条采用PDLC或者电致变色材料制作形成，可以根据用户的视角的范围而选择是否给采用PDLC或者电致变色材料形成的遮光条施加电压，以保证用户的视角在显示器的可视角度范围内，并且不降低显示器的开口率。
本发明的实施例提供的显示面板，在彩膜基板的与阵列基板相反的一侧且与黑矩阵中的矩阵条对应的位置处设置有由PDLC材料或者电致变色材料形成的遮光条，当用户的视角在显示器的可视角度范围内时，给遮光条施加电压使得遮光条呈现透明状态；当用户的视角超过显示器的可视角度范围时，不给遮光条施加电压，使得遮光条呈现不透光状态，从而使得显示器的透光面积保持不变，从而在增加显示器的可视角度的同时保证了较高的开口率。而且，提高了显示器的亮度，提高了图像质量。
示例性地，参照图3所示，该显示面板的电极10包括：第一透明导电层8和第二透明导电层9，其中：第一透明导电层8形成在彩膜基板4和遮光条7之间。
示例性地，遮光条7完全覆盖第一透明导电层8。
示例性地，第一透明导电层8包括多个第一透明电极条。
示例性地，第一透明导电层8的每个第一透明电极条的宽度与遮光条的宽度相同。
第二透明导电层9形成在遮光条7上，完全覆盖遮光条7和彩膜基板4。
示例性地，第一透明导电层和第二透明导电层均可以采用混合有氟的氧化铟锡(Indium Tin Oxide，简称ITO)、氧化锌或氧化铟锌等无机材料制作形成。第一透明导电层和第二透明导电层均可以是采用喷墨打印、蒸镀或者光刻等工艺形成的。
本实施例中提供的显示面板中的遮光条的材料为PDLC，当用户与显示 装置相对的垂直视角在显示装置的可视角度A范围内时，可以采用给第一透明导电层和第二透明导电层施加电压，从而在第一透明导电层和第二透明导电层之间产生电场，给具有PDLC材料的遮光层施加电场，从而PDLC材料的性质发生变化，使得遮光条呈现透明状态，进而不影响光透过即透光面积不变，保证了显示装置的开口率。当用户与显示装置相对的垂直视角超出显示设备的可视角度A范围时，不给第一透明导电层和第二透明导电层施加电压，遮光条上的PDLC材料发生可逆变化，从而使得遮光条呈现不透明状态，进而光线经过矩阵条打到遮光条上的光被挡住，可以通过的光线为打到遮光条最左侧的光线，这样显示设备的最大可视角度A＝2arc tan(h/D)；其中，h为遮光条的宽度，D为遮光条与矩阵条之间的距离。因此，明显的可以得到显示装置的可视角度A变大。同时，显示装置的开口率相比较之前也保持不变。从而在增大显示设备的视角的同时，保证了显示设备的开口率。
示例性地，遮光条7的宽度大于或等于黑矩阵中矩阵条41的宽度。
黑矩阵中矩阵条41的宽度小于或等于预设宽度。
示例性地，黑矩阵中的矩阵条的宽度的变化范围此处不作唯一的限定，但是必须满足显示设备的最大可视角度在通过本发明实施例中的改进之后比现有技术方案中的大。
示例性地，PDLC材料或者电致变色材料可以是通过涂敷工艺完成的，涂敷完成后，可以采用紫外光照射使得PDLC材料或者电致变色材料固化成型。
示例性地，该预设宽度是发明人已知的矩阵条的宽度。本实施例中的矩阵条的宽度小于现有方案中的矩阵条的宽度，但是并没有影响显示器的开口率和显示亮度，在实际的生产中需要的制作矩阵条的材料减少，极大的节省了生产成本。
当该显示面板为用于三维(three dimensional，简称3D)显示装置的显示面板时，参照图4所示，示例性地，该显示面板还包括：
形成在阵列基板3的远离彩膜基板4的一侧并覆盖阵列基板3的第一偏光片2。
形成在遮光条7上并覆盖遮光条7和彩膜基板4的第二偏光片5。

可选的，当该显示面板为用于3D显示装置的显示面板时，参照图5所示，显示面板的遮光条的上下两个面上分别有第一透明导电层和第二透明导电层时，另一种可行的方案为：
第二偏光片5可以是形成在第二透明导电层9上并完全覆盖第二透明导电层9。
