Description

显示模组及显示系统 技术领域
本发明的实施例一般地涉及显示技术领域，尤其涉及一种显示模组及显示系统。
背景技术
现有的显示装置一般分为平面显示装置和曲面显示装置，其中，平面显示装置相对于曲面显示装置，由于其具有节省物理空间的优点而得到广泛应用，然而平面显示装置的出射光的强度的分布如图1(a)和图1(b)(图1(b)中X轴表示显示装置的其它位置到中间位置的距离；Y轴表示光的强度)所示，由显示装置的中间位置向两边光的强度依次减弱，因而给人眼的视觉体验不好，尤其是对大型的显示装置，显示装置两边的光的强度将更弱。
曲面显示装置是将显示装置做成有一定的弧度，如图2所示，使得显示装置的不同位置均正对人眼，这样可以使人获得最佳的视觉体验。但是这种曲面设计只能使在显示装置中间位置观看的人感觉到舒服，而并不能兼顾其它观看位置，且曲面设计使得显示装置占用的物理体积较大，从而使得曲面显示装置的应用受到一定限制。
发明内容
本发明的实施例提供一种显示模组及显示系统，可达到曲面显示的效果，且解决了曲面显示装置占用的物理空间较大的问题。
根据本发明的一方面，提供一种显示模组，包括显示面板和调光结构，所述调光结构设置于所述显示面板的出光侧；所述调光结构被构造成对所述显示面板发出的光进行调节，以使从所述显示面板发出的光向靠近人眼 位置处折射。

优选地，所述液晶层中的液晶分子的偏转角度能够由所述公共电极和所述电极组控制，使得液晶层呈现为等效光学组件，该等效光学组件使从显示面板发出的光向靠近人眼位置处折射。

优选地，每个电极组或每个电极能够被单独地施加电压。
优选地，所述显示面板为液晶显示面板或有机电致发光二级管显示面板。
进一步优选地，在所述显示面板为液晶显示面板的情况下，所述显示模组还包括彩色膜层或分光膜层；其中，所述彩色膜层或分光膜层设置在所述调光结构上，或者，所述彩色膜层或分光膜层设置在所述液晶显示面板上。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，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。
本发明实施例提供一种显示模组，如图3所示，包括显示面板10和调光结构20，调光结构20设置于显示面板10的出光侧。
调光结构20被构造成对显示面板10发出的光进行调节，以使从显示面板10发出的光向靠近人眼位置处折射。
其中，对于调光结构20的具体结构，以能对显示面板10发出的光进行调节，并使显示面板10发出的光向靠近人眼位置处折射为准。
需要说明的是，从显示面板10发出的光向靠近人眼位置处折射是指通过调节结构20可以调节显示面板10发出的光折射向人眼方向，但不限于折射向人眼，可以是人眼周围。
此处，对于调光结构20和显示面板10之间如何固定不进行限定，例如可以利用OCA((Optically Clear Adhesive，光学胶)将调光结构20和显示面板10固定(图3中未示意出OCA)。
根据本发明实施例提供的显示模组，由于调光结构可以调节显示面板发出的光向靠近人眼位置处折射，可以使得显示面板的不同位置发出的光均朝向人眼位置处折射，因而可实现曲面显示的效果，且使得人眼位置处即为视角最佳位置处，避免了现有的平面显示面板从中间位置向两边位置光的强度依次减弱的问题，且避免了现有曲面显示面板只有中间位置处为视角最佳位置处的问题。进一步地，由于本发明实施例中的显示模组是平面显示模组，其是通过光学的方法实现曲面显示效果，因而也解决了曲面显示装置占用的物理空间较大的问题。
优选地，如图4和图5所示，调光结构20为液晶面板30。液晶面板30包括对盒的第一基板301和第二基板302、以及设置在第一基板301和第二基板302之间的液晶层303。
第一基板301或第二基板302上设置有多个电极组40，每个电极组 40包括多个相互绝缘的电极401。
本领域技术人员应该明白，为了能够驱动液晶层303中的液晶分子发生偏转，上述液晶显示模组还包括公共电极50，公共电极50和电极组40可以设置在不同的基板上，共同驱动液晶分子偏转。例如，电极组40设置在第一基板301上，公共电极50设置在第二基板302上；或者，电极组40设置在第二基板302上，公共电极50设置在第一基板301上。在一个示例中，公共电极50可以设置成面状或板状。本发明实施例中以公共电极50设置在第二基板302为例进行示意。
本发明实施例通过液晶面板30调节显示面板10发出的光的方向的原理为：如图5所示，在施加在公共电极50上的电压相同或恒定的情况下，通过控制施加在电极组40中电极401上的电压发生变化，便可以控制与电极组40对应位置处的液晶分子的偏转状态发生变化，从而可以使得液晶层在与各个电极组40对应位置处的部分呈现不同的折射率，以使从显示面板10发出的光向靠近人眼位置处折射。当控制液晶面板30将显示面板10发出的光向靠近人眼位置处折射时，人眼位置处即为视角最佳位置处。
基于上述描述，本发明实施例中，控制液晶面板30中的液晶分子的偏转状态，便可以调节显示面板10发出的光向靠近人眼位置处折射，此时，液晶面板30中的液晶层的作用相当于一个光学组件，因而液晶层实际上可等效形成光学组件。其中，等效形成的光学组件例如可以是棱镜或透镜。
此处，通过控制施加在电极组40中电极401上的电压，可以使液晶面板30中的液晶层等效形成多种形态的光学组件。
示例性地，通过控制施加在电极组40中电极401上的电压，可以使液晶层与电极组40对应位置处的部分等效形成例如图6(a)和图6(b)所示的棱镜的形态。当控制施加在电极组40中电极401上的电压，使液晶层 等效形成如图6(a)所示的棱镜时，此时显示面板10发出的光均向中间位置折射，因此中间位置为视角最佳位置处；当控制施加在电极组40中电极401上的电压，使液晶层等效形成如图6(b)所示的棱镜时，此时由于显示面板10发出的光均向右侧位置折射，因此右侧位置为视角最佳位置处。
当然，通过控制施加在电极组40中电极401上的电压，还可以使液晶层与电极组40对应位置处的部分等效形成例如图7(a)或图7(b)所示的透镜形态。当控制施加在电极组40中电极401上的电压，使液晶等效形成如图7(a)所示的透镜时，此时显示面板10发出的光均向中间位置折射，因此中间位置处为视角最佳位置处；当控制施加在电极组40中电极401上的电压，使液晶层等效形成如图7(b)所示的透镜时，此时显示面板10发出的光均向右侧位置折射，因此右侧位置处为视角最佳位置处。
此处，控制施加在电极组40中电极401上的电压，使液晶层等效形成的光学组件并不限于图6(a)或图6(b)所示的棱镜，也不限于图7(a)或图7(b)所示的透镜，还可以是其它任意的光学组件。
需要说明的是，对于每个电极组40中电极401的个数应根据电极401的大小进行合理设置。
其中，每个电极401上施加的电压均可以单独控制，具体的，可根据人眼位置，控制电极组40中各电极401上施加的电压。
对于电极组40中电极401的形状不进行限定。
本发明实施例中，由于液晶面板30上设置有多个电极组40，每个电极组40中包括多个相互绝缘的电极401，因此可通过控制施加在电极组40中电极401上的电压，来控制液晶分子的偏转角度，而使得液晶层303与每个电极组40对应位置处的部分的等效折射率发生变化，从而调节显示面板10发出的光均向靠近人眼位置处折射。
优选地，电极组40包括多个条状电极401或多个阵列排布的电极401。
其中，对于条状电极，例如可以是如图8(a)所示的连续的条状电极 401，也可以是如图8(b)所示的不连续的条状电极401。对于阵列排布的多个电极401的形状，例如可以是如图8(b)所示的条状阵列；也可以是如图8(c)所示的方形阵列；或者是如图8(d)所示的圆形阵列。
优选地，显示面板10为液晶显示面板或有机电致发光二级管显示面板。
说明性地，如图9(a)所示，当显示面板10为液晶显示面板时，该液晶显示面板包括阵列基板101、对盒基板102及位于阵列基板101和对盒基板102之间的液晶层104。
在一个示例中，阵列基板101上的每个亚像素均可以包括薄膜晶体管和像素电极，像素电极与薄膜晶体管的漏极电联接；公共电极可以位于阵列基板101上或对盒基板102上。
如图9(b)所示，当显示面板10为有机电致发光二极管显示面板时，有机电致发光二极管显示面板的每个亚像素103均可以包括阳极1031、有机材料功能层1032以及阴极1033。其中，有机材料功能层1032至少包括发光层。
在此基础上，每个亚像素103还可以包括薄膜晶体管，且薄膜晶体管的漏极与阳极1031电联接。
进一步优选地，为了实现彩色显示，在显示面板10为液晶显示面板的情况下，显示模组还包括彩色膜层或分光膜层；其中，彩色膜层或分光膜层设置在调光结构20上，或者，彩色膜层或分光膜层设置在液晶显示面板上。
其中，对于彩色膜层和分光膜层的设置位置不进行限定，只要能实现彩色显示即可。
此处，分光膜层可将经过分光膜层的白光分成不同颜色的光，从而实现彩色显示。
需要说明的是，无论是将彩色膜层设置在调光结构20上，还是设置 在显示面板10上，彩色膜层中的光阻都应和显示面板10上的亚像素一一对应。
本发明实施例还提供一种显示系统，包括上述的显示模组。
本发明实施例提供的显示系统包括上述的显示模组，因而可以使得显示面板10不同位置发出的光均向靠近人眼位置处折射，从而使得人眼位置处即为视角最佳位置处。
优选地，上述显示系统还包括摄像头和控制器；摄像头用于追踪人眼位置；控制器用于控制调光结构20，使经调光结构20调节后的光，根据人眼位置的变化实时向靠近人眼位置处折射。
本发明实施例由于设置有摄像头和控制器，通过摄像头追踪到人眼位置后，可以通过控制器控制显示面板10发出的光经调光结构20调节后射向摄像头追踪到的人眼位置处，这样便可以确保无论人眼位置是在显示系统的中间位置还是两边位置，人眼位置处都为视角最佳位置处。
优选地，上述显示系统还包括与调光结构20相连的切换器；切换器用于控制调光结构20对显示面板10发出的光调节与否，以实现平面显示效果和曲面显示效果的转换。
其中，切换器用于根据用户需求控制调光结构20对显示面板10发出的光调节与否。当切换器控制调光结构20对显示面板10发出的光进行调节时，调光结构20便调节显示面板10发出的光向靠近人眼位置处折射，从而使得人眼位置为视角最佳位置处，此时可实现曲面显示的效果。当切换器控制调节结构20不对显示面板10发出的光进行调节时，显示面板10发出的光将不受调光结构20的影响，此时显示面板10即相当于一个正常的平面显示面板，此时可实现平面显示的效果。
本发明实施例，可根据用户需求控制调光结构20对显示面板10发出的光调节与否，满足用户的各种需求。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局 限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
