Description

显示面板及其制造方法、显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板及其制造方法、显示装置。
背景技术
随着显示技术的发展和显示需求的提高，对显示装置、尤其是曲面显示装置的要求也逐渐提高。曲面显示装置具备的优点在于观看者处于合适位置时，眼睛到曲面显示装置的显示面板的各点的距离大致相同，理论上可以达到更好的观看效果。
现有技术中，通常是利用机械力使显示面板发生弯曲后，通过形状固定的曲形背板将其形状固定，最终形成曲面显示装置。但是，在通过机械力使显示面板发生弯曲以形成曲面显示面板后，显示面板的曲率是固定的。当观看者处于不同位置时或不合适的位置时，观看者的眼睛到曲面显示装置的显示面板的各点的距离会有较大的差异，使得观看效果不佳。
因此，基于现有技术制造的曲面显示装置，无法适应观看者位置的改变，缺乏灵活性。

具体实施方式
下面结合说明书附图对本发明实施例的实现过程进行详细说明。需要注意的是，自始至终相同或类似的附图标记表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
参见图1，本发明实施例提供一种显示面板，包括相对设置并封装在一起的上基板1和下基板2。所述显示面板还包括电控变形膜层3，电控变形膜层3设置于上基板1的背向下基板2的表面上。
电控变形膜层3配置为根据施加到电控变形膜层3上的电压调节自身的曲率，并使得上基板1的曲率和下基板2的曲率同步调节。例如，电控变形膜层3配置为能够根据施加到电控变形膜层3上的电压的幅度调节自身的曲率。
本实施例中，通过在上基板1的背向下基板2的表面上设置可调曲率的电控变形膜层3，在需要调节显示面板曲率时，可以改变施加于电控变形膜层3的电压，使电控变形膜层3的曲率改变并带动封装在一起的上基板1和下基板2同步改变曲率，以适应观看者位置的变化，实现显示面板曲率的灵活调节。
电控变形膜层3可以由电致感应材料形成，电致感应材料可以为电致感应形状记忆聚合物(Shape Merrory Polyers，SMP)。电致感应SMP材料既有导电性能，又有良好的形状记忆功能。能够通过调节施加到电控变形膜层上的电压改变曲率，从而使封装在一起的上基板和下基板的曲率同步调节，以实现对于显示面板的曲率的灵活调节。可 选的，电控变形膜层3的形状和大小与上基板1匹配，电控变形膜层3的不同端可以分别与下基板2上的电源信号线和接地信号线电连接。需要说明的是，电控变形膜层3的不同端可以是电控变形膜层3的相邻的端，也可以是相对的端。例如，在电控变形膜层3为矩形形状时，电控变形膜层的不同端可以是矩形的相邻的两边所对应的端部，也可以是矩形的对边所对应的端部。为了使电控变形膜层3加电后的形变符合显示面板的形变要求，可以选择电控变形膜层3的相对的两端分别与下基板2上的电源信号线和接地信号线电连接。其示意图如图3所示，电控变形膜层3的一端与电源V电连接，另一端与地GND电连接。当然，也可以使电控变形膜层的多个端部中的一端或两端与电源V电连接，并且使没有与电源V电连接的其它端部中的一端或两端与地GND电连接。通过使电控变形膜层3的不同端分别与电源信号线和接地信号线电连接，可以使电控变形膜层3能够更好的被控制，从而避免发生局部形变过大或过小。电控变形膜层3也可以与显示面板之外的电源和地电连接，即，在显示面板之外为电控变形膜层3供电。但是基于简化显示面板的外部结构和减少显示面板整体体积的考虑，例如，电控变形膜层3的不同端可以直接与下基板2上的电源信号线和接地信号线电连接。即，电源信号线和接地信号线设置于下基板2上，由此减少显示面板的整体体积。如图2所示，提供第一导电部件4和第二导电部件5。电控变形膜层3的一端可以通过第一导电部件4与下基板2上的电源信号线(未示出)电连接，电控变形膜层3的另一端可以通过第二导电部件5与下基板2上的接地信号线(未示出)电连接。当然，如果需要使显示面板在形变时为特殊的曲面，可以使电控变形膜层3的相邻端分别与下基板2上的电源信号线和接地信号线电连接；或者，可以使电控变形膜层3的多个端部中的一端与下基板2上的电源信号线电连接，其它端与接地信号线电连接，在此不再赘述。
为了对电控变形膜层的供电线路进行保护，提高显示面板的安全性，可以有如下设置：下基板2的朝向上基板1的表面上设置有与电源信号线电连接的供电保护电路6，电控变形膜层3的相对的两端中的一端通过第一导电部件4与供电保护电路6电连接。供电保护电路6的数目例如可以为多个。供电保护电路6与电控变形膜层3连接的示意图如图4所示。本实施例中，通过供电保护电路6对电控变形膜层3 的供电线路进行保护。
可选的，供电保护电路6包括第一薄膜晶体管M1，具体的连接方式可以如图5所示，第一薄膜晶体管M1的栅电极和源电极与电源信号线电连接，第一薄膜晶体管M1的漏电极与第一导电部件4电连接。本实施例中，以二极管方式连接的第一薄膜晶体管M1作为供电保护电路6，这样的供电保护电路容易实现。此外，在下基板2为阵列基板时，可以与下基板2上的用于驱动像素阵列的薄膜晶体管同步形成供电保护电路，由此可以节省工序。
为了对显示面板进行静电防护，提高显示面板的安全性，可以有如下设置：下基板2朝向上基板1的表面上设置有与接地信号线电连接的静电防护电路7，电控变形膜层3的相对的两端中的另一端通过第二导电部件5与静电防护电路7电连接。静电防护电路7的数目例如可以为多个。静电防护电路7与电控变形膜层3连接的示意图如图6所示。本实施例中，通过设置与电控变形膜层3电连接的静电防护电路7，可以使电控变形膜层3作为显示面板的静电防护层，为显示面板提供静电防护。
可选的，静电防护电路7包括第二薄膜晶体管M2和第三薄膜晶体管M3，具体的连接方式可以如图7所示，第二薄膜晶体管M2的栅极和源电极、第三薄膜晶体管M3的漏电极与第二导电部件5电连接，第二薄膜晶体管M2的漏电极、第三薄膜晶体管M3的栅电极和源电极与接地信号线电连接。本实施例中，以二极管方式连接的第二薄膜晶体管M2和第三薄膜晶体管M3作为静电防护电路，这样的静电防护电路容易实现。此外，在下基板2为阵列基板时，可以与下基板2上的用于驱动像素阵列的薄膜晶体管同步形成静电防护电路，由此可以节省工序。
电控变形膜层3用于供电线路保护、静电防护的具体说明如下。
如图8所示，在显示面板工作正常时，电源V提供直流高电平，电流I依次流经第一薄膜晶体管M1、电控变形膜层3、第二薄膜晶体管M2，最终至地GND。
如图9所示，在显示面板工作过程中在表面聚集较多的正电荷时，可视为由电源V1提供交流电压，电流I依次流经电控变形膜层3、第二薄膜晶体管M2，最终至地GND。
如图10所示，在显示面板工作过程中在表面聚集较多的负电荷时，可视为由电源V1提供交流电压，地GND的电压高于电控变形膜层3上的负电荷的电压，因此地GND向电控变形膜层3放电，电流I依次流经第三薄膜晶体管M3至电控变形膜层3。
需要说明的是，在下基板2为阵列基板的情况下，下基板2上形成有像素单元阵列，像素单元阵列通常设置有GOA电路。该GOA电路可以设置于像素单元阵列的一边(即单边驱动)，也可以设置于像素单元阵列的两边(即双边驱动)。可选的，GOA电路设置于像素单元阵列的两边，从而使两则的非显示区均匀，有利于实现窄边框的显示面板。相应的，与电控变形膜层3电连接的电源信号线和提供供电线路保护的供电保护电路6设置于像素单元阵列的一边，与电控变形膜层3电连接的接地信号线和提供静电防护的静电防护电路7可以设置于像素单元阵列的另一边。
可选的，电控变形膜层3的材料为电致感应SMP材料。本实施例中，电致感应SMP材料既有导电性能，又有良好的形状记忆功能。能够通过调节施加到电控变形膜层上的电压改变其曲率，从而使封装在一起的上基板1和下基板2的曲率同步调节，由此实现对于显示面板曲率的灵活调节。
可选的，电控变形膜层3的厚度为100um至200um。
可选的，下基板2为阵列基板，上基板1为彩膜基板或封装基板。例如，在显示面板为液晶显示装置的显示面板的情况下，上基板1为彩膜基板，下基板2为阵列基板。当然，相应的还需要在上基板1和下基板2之间设置液晶。又例如，在显示面板为LED显示装置的显示面板的情况下，上基板1为封装基板，下基板2为阵列基板。当然，相应的还需要在下基板2上设置LED发光器件。在此不再赘述。
本发明实施例的有益效果如下：通过在上基板的背向下基板的表面上设置可调曲率的电控变形膜层，在需要调节显示面板的曲率时，可以改变施加于电控变形膜层的电压，使电控变形膜层的曲率改变并带动封装在一起的上基板和下基板同步改变曲率，以适应观看者位置的变化，实现显示面板曲率的灵活调节。

可选的，所述方法还可以包括：在封装上基板和下基板之前，在下基板上形成供电保护电路和静电防护电路，供电保护电路与电源信号线电连接，静电防护电路与接地信号线电连接。在所形成的显示面板中，可以使供电保护电路设置于下基板上的电源信号线及与电源信号线电连接的第一导电部件之间，并且使静电防护电路设置于下基板上的接地信号线及与接地信号线连接的第二导电部件之间。
本发明实施例的有益效果如下：通过在上基板的背向下基板的表面上设置可调曲率的电控变形膜层，在需要调节显示面板的曲率时，可以改变施加于电控变形膜层的电压，使电控变形膜层的曲率改变并带动封装在一起的上基板和下基板同步改变曲率，以适应观看者位置的变化，实现对于显示面板曲率的灵活调节。
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。
