Description

拼接式显示屏 技术领域
本发明涉及显示技术领域，尤其涉及一种拼接式显示屏。
背景技术
在显示技术领域，液晶显示屏(Liquid Crystal Display，LCD)与有机发光二极管显示屏(Organic Light Emitting Diode，OLED)等平板显示装置已经逐步取代CRT显示屏。
LCD屏包括液晶显示面板、及背光模组，液晶显示面板本身不发光，需要由背光模组提供光源。进一步地，液晶显示面板由一彩色滤光片基板(Color Filter，CF)、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)、以及一填充于两基板间的液晶层(Liquid Crystal Layer)所构成，且CF基板与TFT基板均采用刚性的玻璃作为衬底，所以平板形式的液晶显示面板不可弯折。
OLED屏与LCD屏相比，具有薄、轻、宽视角、主动发光、发光颜色连续可调、成本低、响应速度快、能耗小、驱动电压低、工作温度范围宽、生产工艺简单、发光效率高及可柔性显示等优点，被誉为“梦幻显示器”。OLED屏按照驱动方式可以分为无源矩阵型(Passive Matrix，PM)OLED和有源矩阵型(Active Matrix，AM)OLED两大类，即直接寻址和薄膜晶体管(Thin Film Transistor，TFT)矩阵寻址两类。
现如今，拼接式显示屏在户外传媒、展馆、广场、演艺场所、监控设施等处广泛使用，供大众观看。如图1所示，现有的将数块液晶显示面板101拼接在一起的LCD拼接式显示屏100，由于各液晶显示面板101使用以刚性的玻璃作为衬底的CF基板与TFT基板，且每一液晶显示面板101均具有外围边框，在拼接处不可避免地存在黑区或黑线，造成画面看起来不流畅。
因此，有必要对拼接式显示屏进行改进，以改善观看效果，提升显示质量。
发明内容
本发明的目的在于提供一种拼接式显示屏，能够消除拼接处的黑区或黑线，使画面显示流畅，改善拼接式显示屏的观看效果。

在每相邻两块OLED显示屏的拼接处，该相邻两块OLED显示屏的非显示区均朝向弹性基板背后弯折，使得该相邻两块OLED显示屏的有效显示区无缝对接。
所述弹性基板的材料为聚酰亚胺。
所述弹性基板的材料为聚对苯二甲酸乙二酯。
所述非显示区内设置有OLED面板的驱动器，所述驱动器采用碳纳米管制作。

所述薄膜晶体管设在缓冲层上，所述缓冲层设在弹性基板上。
所述碳纳米管通过蒸镀制作在弹性基板上。
本发明还提供一种拼接式显示屏，包括数块相互拼接的OLED显示屏；每一OLED显示屏包括弹性基板、以及设在所述弹性基板上的OLED面板；所述OLED显示屏具有有效显示区、及位于所述有效显示区外围的非显示区；
在每相邻两块OLED显示屏的拼接处，该相邻两块OLED显示屏的非显示区均朝向弹性基板背后弯折，使得该相邻两块OLED显示屏的有效显示区无缝对接；
其中，所述非显示区内设置有OLED面板的驱动器，所述驱动器采用碳纳米管制作；

具体实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请同时参阅图2、图3、与图4，本发明提供一种拼接式显示屏，包括数块相互拼接的OLED显示屏1；每一OLED显示屏1包括弹性基板11、以及设在所述弹性基板11上的OLED面板13。OLED显示器件具有自发光的特性，无需为所述OLED面板13配置背光模组，因此由所述数块OLED显示屏1构成的拼接式显示屏更轻便、方便搬运和携带。
所述OLED显示屏1具有有效显示区AA、及位于所述有效显示区AA外围的非显示区DD，具体地，所述有效显示区AA对应于所述OLED面板13内排布有OLED显示器件能够实现显示功能的区域。
具体地，所述弹性基板11的材料优选为聚酰亚胺(Polymide，PI)或聚对苯二甲酸乙二酯(Polyethylene Terephthalate，PET)。
将弹性基板11远离OLED面板13的一侧定义为弹性基板11的背后，鉴于弹性基板11的材料性质具有可弯折性，在每相邻两块OLED显示屏1的拼接处，该相邻两块OLED显示屏1的非显示区DD均朝向弹性基板11背后弯折，使得该相邻两块OLED显示屏1的有效显示区AA无缝对接，能够消除拼接处的黑区或黑线，制作出无黑区或黑线的拼接式显示屏，使画面显示流畅，改善拼接式显示屏的观看效果。
具体地，所述非显示区DD内设置有OLED面板13的驱动器以及集成了面板周边电路的印刷电路板。由于非显示区DD要发生弯折，所述驱动器及印刷电路板均采用具有优异柔性的碳纳米管制作，防止驱动器及印刷电路板因弯折而断裂。
结合图5，所述有效显示区AA内设置有OLED面板13的驱动电路L，为了防止所述有效显示区AA靠近非显示区DD的部分内的驱动电路L因非显示区DD朝向弹性基板11背后弯折而出现断裂，所述驱动电路L亦采用具有优异柔性的碳纳米管制作。
所述碳纳米管通过蒸镀制作在弹性基板11上。
进一步地，所述驱动电路L包括多个薄膜晶体管T，所述薄膜晶体管T包括栅极21、覆盖所述栅极21的第一绝缘层22、设在所述第一绝缘层22上的有源层23、分别设在有源层23两侧上的源极241与漏极242、及覆盖所述有源层23、源极241、与漏极242的第二绝缘层25。所述薄膜晶体管T设在缓冲层20上，所述缓冲层20设在弹性基板11上。所述驱动电路L还包括设于第二绝缘层25上并通过贯穿第二绝缘层25的过孔与漏极242接触的阳极26。
综上所述，本发明的拼接式显示屏，对用于拼接的每一OLED显示屏设置弹性基板、以及设在所述弹性基板上的OLED面板，在每相邻两块OLED显示屏的拼接处，该相邻两块OLED显示屏的非显示区均朝向弹性基板背后弯折，使得该相邻两块OLED显示屏的有效显示区无缝对接，从而能够消除拼接处的黑区或黑线，使画面显示流畅，改善拼接式显示屏的观看效果。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明后附的权利要求的保护范围。
