技术领域
本发明涉及显示技术领域，尤其涉及一种改善显示面板的大视角色偏的方法以及对应的显示面板。
背景技术
近年来，大尺寸显示面板在一般终端市场中的占比份额逐渐提高。然而，当显示面板尺寸逐渐加大后，使用者的视角范围也相应增加，这导致显示面板因大视角所引起的色度偏差问题逐步显现。
图1为当视角变化时显示面板发出的各波长的光的强度变化示意图。如图1所示，当视角由0°增加至60°后，用虚线箭头指示出了波长强度峰值的衰减情况。其中，在强度变化方面，蓝色波长(450-470nm)的强度衰减最为明显，而绿色波长(515-530nm)和红色波长(620-625nm)的强度衰减较不明显，从而导致了白点色度的偏移，影响了面板的显示效果。图2为白点色偏示意图(CIE 1931 xy)。如图2所示，当视角加大后，白点坐标从E点向箭头所示方向偏移。
发明内容
本发明提供了一种改善显示面板的大视角色偏的总的发明构思，以解决上述大视角色偏的技术问题。本发明通过对子像素增加遮挡的方式对子像素透射的光强度随视角的衰减差异进行补偿，从而改善显示面板的大视角色偏现象。

本发明所实现的有效效果是：通过对子像素增加遮挡的方式对子像素透射的光强度随视角的衰减差异进行补偿，从而改善了显示面板的大视角色偏现象，。
本发明的其它特征和优点将在随后的说明书中阐述，并且部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及说明书附图中所特别指出的结构来实现和获得。

具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
图3和图4共同示出了根据本发明的一实施例在显示面板中设置的光栅结构示意图，其中图3是侧面结构示意图，而图4是正面结构示意图。从图3和图4可以看出，在该实施例中，显示面板包括R、G、B子像素阵列301以及各子像素之间的BM区(即，不发光区域)。在子像素阵列301上方设置有与子像素阵列301平行的光栅302。该光栅302包括透光区303和不透光区304，不透光区304设置于BM区上方。
在图3和图4所示出的实施例中，仅在G子像素两侧的BM区上方设置光栅302的不透光区304。但这仅仅是示例性的而非限制性的。在另一实施例中，可以在G子像素两侧和R子像素两侧的BM区上方都设置有光栅302的不透光区304。
由于光栅302的不透光区304仅设置于BM区上方，因此光栅302不会对正面视角的显示造成影响。在图3和图4所示出的实施例中，随着视角增大，子像素G的光强度会受到光栅302的不透光区304的遮挡影响，从而在子像素G的光强度自身随视角衰减的基础上增加光栅302的不透光区304的遮挡造成的光强度衰减。光栅302的具体参数，例如不透光区304的大小和高低、不透光区304相对于子像素的位置等，可根据子像素随视角的光强度衰减情况进行设置。光栅302的不透光区304的形状也可以根据子像素阵列 的排列方式进行调整。
图5为不同视角下光栅对子像素的光强度衰减的示意图。如图5所示，随视角增大，子像素的光强度逐渐减小。图6为通过光栅对色偏进行改善的效果示意图。
设R、G、B子像素本身在视角为θ时的光强度衰减率分别为fR(θ)、fG(θ)、fB(θ)，视角为0时R、G、B透射的光强度分别为LvR、LvG、LvB，则视角θ对应的R、G、B光强度LvR′、LvG′、LvB′分别为：
Figure PCTCN2017092689-appb-000001
由于fR(θ)、fG(θ)、fB(θ)各不相同，所以LvR′:LvG′:LvB′≠LvR:LvG:LvB，并且其中fB(θ)衰减更明显，所以白点色坐标会发生偏移，例如在图6中从E点偏移到A点，颜色偏黄。
根据图3和图4所示出的实施例设置光栅302后，假定光栅302对光强度的衰减率为fbarrier(θ)，则视角θ对应的R、G、B光强度LvR″、LvG″、LvB″分别为：
Figure PCTCN2017092689-appb-000002
其中，使fG(θ)*fbarrier(θ)＝fB(θ)则可以将色差降低，例如在图6中白点坐标偏移到Ac点。由此可见通过设置光栅302对色偏进行了改善。
图7为根据本发明的一实施例在显示面板中设置的光栅的正面结构示意图。在该实施例中，可以在G子像素两侧和R子像素两侧的BM区上方都设置有光栅302的不透光区304。与上述结合图3-6所描述的实施例原理类似，通过设置光栅302可以对色偏进行改善。光栅302的不透光区304的参数可以根据R、G、B子像素的光强度衰减情况进行设置。光栅302的具体形状也可以根据像素阵列的排列方式进行调整。
图8为顶部发光型OLED的结构示意图。顶部发光型OLED从下往上包括：基层801、TFT(薄膜晶体管)、阳极802、PDL层(即，像素界定层)、发光层803、透明阴极804、彩色滤光片805以及玻璃806。在图8所示的实施例中，可以通过调整G子像素的对应PDL层的厚度H来调整G子像素随视角的光强度衰减情况。PDL层的厚度调整参数可以根据R、G、B子像素的光强度衰减情况进行设置。如图所示，增加G子像素的 PDL层的厚度H，这样由G子像素透射的光在大视角时被PDL层部分遮挡，因而G子像素的光强度发生衰减，从而可以使得在大视角时R、G、B子像素的光强度衰减相当，因此改善了由R、G、B子像素本身在大视角时的光强度衰减不一致造成的色偏现象。
在图8所示的实施例中，仅对G子像素的PDL层的厚度进行了调整。在不同的实施例中，可以对G子像素和R子像素的PDL层的厚度都进行调整。PDL层的厚度调整参数可以根据R、G、B子像素的光强度衰减情况进行设置。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
