Description

柔性显示屏和显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种柔性显示屏和显示装置。
背景技术
目前，柔性显示屏由于具备自发光、可弯折挠等优点，因此具有非常好的发展前景。显示屏包括显示区和连接显示区的引线区，引线区设置有连接显示区的引线。为了提高显示区相对于显示屏的占比和实现窄边框，引线区一般弯折设置。然而，现有外接驱动芯片的柔性显示屏在引线区弯折后，使得显示区难以弯折，因此，现有的外接驱动芯片的柔性显示屏无法兼顾窄边框显示和具有弯折性。

下文的公开提供了许多不同的实施方式或例子用来实现本发明的不同结构。为了简化本发明的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本发明。此外，本发明可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。此外，本发明提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
请一并参阅图1-图3，本发明实施方式的柔性显示屏100包括显示区10和引线区20。引线区20连接显示区10边缘。引线区20包括呈弯折状的多个弯折部22，沿弯折部22弯折的方向R，弯折部22呈渐缩形状，相邻的两个弯折部22之间与显示区10限定有柔性显示屏100的弯折轴102。
上述柔性显示屏100中，呈弯折状的弯折部22可减小柔性显示屏100的边框，并且，弯折部22呈渐缩形状使得相邻两个弯折部22之间与显示区10可限定出弯折轴102，使得柔性显示屏100可以沿着弯折轴102弯折，从而使得柔性显示屏100可以同时兼顾窄边框显示和具有弯折性。
具体地，引线区20上形成有多条引线24，引线24用于与外部电路连接。沿弯折部22弯折的方向，多条引线24聚拢以使引线24的排布形状与弯折部22相配。
可以理解，显示区10包括显示面12和背面14。显示面12和背面14相背设置。显示面12用于显示信息，例如文字及图像等信息。
在一个例子中，在制造柔性显示屏100时，可先将一整块的显示屏切割以形成显示区10和引线区20，并使弯折部22在平铺时沿远离显示区10的长边缘15方向呈渐缩形状，然后在引线区20上形成聚拢的引线24，最后将带引线24的弯折部22弯折至显示区10的背面14，从而可以使得显示区10的面积与柔性显示屏100的正面轮廓面积比值较大，使得柔性显示屏100具有窄边框显示。
如图3所示，弯折轴102沿Y方向延伸，在弯折部22弯折至显示区10的背面14时，柔性显示屏100可以沿着弯折轴102弯折，以使柔性显示屏100的X方向的区域重叠，如图2所示，从而使得柔性显示屏100具有弯折性，有利于将柔性显示屏100弯折形成不同的形状，例如弧形，对折形等。
在某些实施方式中，柔性显示屏100包括柔性OLED(Organic Light-Emitting Diode，有机发光二极管)。
柔性OLED具有低功耗、制造成本低等优点，从而可以降低柔性显示屏100的成本。
在某些实施方式中，显示区10呈矩形，在弯折部22平铺时，弯折部22沿远离显示区10的长边缘15方向呈渐缩形状，如图3所示。
如此，矩形的显示区10容易制造成型，并符合用户使用柔性显示区10观看显示信息的习惯，从而可以提高用户体验。
在某些实施方式中，弯折部22的数量为两个，两个弯折部22并排设置，两个弯折部22均连接于显示区10的同一个长边缘15，如图3所示。
如此，弯折部22位于显示区10的同一个长边缘15，使得弯折轴102大致与显示区10的短边缘16平行，进而使得柔性显示屏100更加容易沿着弯折轴102弯折。
请参阅图4，在某些实施方式中，引线区20还包括呈矩形的连接部25，相邻的两个弯折部22通过连接部25连接显示区10。连接部25和与连接部25连接的两个弯折部22均位于显示区10的同一长边缘15。
如此，弯折部22弯折至显示区10的背面14后，在显示区10显示信息时，连接部25可呈现为位于显示区10边缘的黑色区域，这样可以适当地增加保证柔性显示屏100的非显示区的面积，从而满足不同的用户需求。
可以理解，连接部24上也形成有连接显示区10的引线，引线可以是直角弯折或直线或它们的组合，设置连接部24可以增加柔性显示屏100可弯折的区域面积。
如图4所示，弯折轴102可以位于弯折区域110内，相较于省略连接部的柔性显示屏100，例如图3的示例，连接部24增加了柔性显示屏100沿X方向的弯折区域面积，有利于柔性显示屏100在不同的位置弯折。
具体地，在一个实施方式中，弯折部22的数量为两个，两个弯折部22并排设置，两个弯折部22通过一个连接部25连接显示区10的同一长边缘15，如图4所示。
如此，由连接部25形成的非显示区位于显示区10的长边缘15一侧，使得柔性显示屏100的布局更加协调，以提高用户体验。
请参阅图5，在另一个实施方式中，显示区10的每个长边缘15均连接有一个连接部25和两个弯折部22，每个长边缘15上的两个弯折部22并排设置。
如此，显示区10的上下边缘位置均形成有非显示区，以满足用户的需求。
综上，弯折部22和连接部25的具体位置可以根据实际情况具体设定。
请再次参阅图3，在某些实施方式中，显示区10呈矩形并包括垂直连接的第一边缘17和第二边缘18，引线区20连接第一边缘17并延伸至第一边缘17与第二边缘18的连接处。
具体地，显示区10包括多列显示像素，显示像素通过引线区20上的引线24与外部电路连接，外部电路通过引线24可以驱动控制显示像素显示不同的信息。
引线区20连接第一边缘17并延伸至第一边缘17与第二边缘18的连接处，使得引线区20上的引线24可以连接显示区10的每一列像素，从而使得外部电路可以驱动显示区10中的每一个区域都能显示信息内容。
请参阅图3-6，在某些实施方式中，柔性显示屏100包括第一电路板40和第一芯片50。第一电路板40连接第二边缘18。第一芯片50设置在第一电路板40上。
第一电路板40例如为柔性电路板，第一电路板40可以连接外部元件，例如电源。第一芯片50可以通过COF(Chip On Flex)技术设置在第一电路板40上。 第一电路板40连接外部电路可以为柔性显示屏100的显示区10提供电压，以使显示区10发光，进而可以显示文字及图像等信息，第一芯片50控制显示区10显示的内容。例如，与引线区20连接的外部电路可用于连接显示区20的列像素电极，第一芯片50可用于连接显示区10的行像素电极。
请参阅图7，在某些实施方式中，柔性显示屏100还包括卷边部30，卷边部30连接第二边缘18并呈弯折状，沿卷边部30弯折的方向，卷边部30呈渐缩形状。第一芯片50设置在卷边部30上，第一芯片50与显示区10电连接。第一电路板40连接卷边部30。
具体地，第一芯片50可以通过COG(Chip On Glass)技术将第一芯片50设置在卷边部30上。在卷边部30平铺时，可先将第一芯片50设置在卷边部30上，然后将带第一芯片50的卷边部30弯折至显示区10的背面14。
可以理解，卷边部30上可形成有引线以连接显示区10及第一芯片50，并连接显示区10及第一电路板40。
请参阅图3-图5，在某些实施方式中，柔性显示屏100包括第二电路板60和第二芯片70，第二电路板60连接弯折部22，第二芯片70设置在第二电路板60上。
具体地，第二芯片70可以为gate(栅极)芯片和/或SD(漏极/源极)芯片。第二芯片70可以驱动显示区10显示文字、图像等内容。
当然，第二电路板60也可以为柔性电路板，第二芯片70例如通过COF技术设置在第二电路板60上。
请参阅图7，在某些实施方式中，第二电路板60可以省略，第二芯片70直接设置在弯折部22上。第二芯片70例如通过COG技术固定在弯折部22上。
本发明实施方式的显示装置包括以上任一实施方式的柔性显示屏100。显示装置可以包括壳体，壳体可以将柔性显示屏100固定形成具体形状。
上述显示装置中，呈弯折状的弯折部22可减小柔性显示屏100的边框，并且，弯折部22呈渐缩形状使得相邻两个弯折部22之间与显示区10可限定出弯 折轴102，使得柔性显示屏100可以沿着弯折轴102弯折，从而使得柔性显示屏100可以同时兼顾窄边框显示和具有弯折性。
显示装置例如是具有以上柔性显示屏100的电视机、手机、平板电脑等电子设备。
