背景技术
窄边框显示屏因其简洁、美观、相同尺寸可视面积大等优点，已成为高品质显示屏的主要发展趋势。随着平板显示的技术的飞速发展，对于窄边框技术提出了更高的要求，柔性显示由于其可弯折性，使其在窄边框技术上具有很大优势。
在现有的柔性显示上实现窄边框，通常为直接减少显示区外围的走线区宽度来实现窄边框效果；或是将两条对边边框区域进行弯曲形成曲面；或是利用将芯片集成在薄膜上的技术来缩小柔性显示屏幕的连接端的边框宽度；然而这些方法只能最多缩小三边的边框宽度，且缩小的程度有限，无法实现四边超窄边框乃至无边框。

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作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。
请参阅图1，本发明提供一种显示面板100，显示面板100具有显示侧和与显示侧相对的背侧。显示面板100包括显示区域10和边框区域20。
显示区域10包括四条边和四个角，所述四个角均非直角。
边框区域20围绕显示区域10，边框区域20内设有与所述四条边平行的四条折痕，所述四条折痕围成一个闭合的折痕框21，折痕框21设于靠近显示区域10的位置，折痕框21与显示区域10的距离优选为0.05mm～1mm。折痕框21将边框区域20划分为第一边框区域22和第二边框区域23。第一边框区域22位于显示区域10和折痕框21之间。第二边框区域23包括四个边框和连接每两个边框的转角部，所述转角部使四个边框沿折痕框21独立折叠。
本实施例中，边框区域20内设有薄膜封装结构24和用于显示区域10内的电路结构。薄膜封装结构24设于所述第二边框区域23内，且所述薄膜封装结构24为封闭封装结构，薄膜封装结构24封装显示面板100并保护显示面板 100，防止水分和氧气进入显示面板100内。所述电路结构位于薄膜封装结构24和显示区域10之间，所述电路结构包括数据信号电路结构和栅极驱动电路结构(GOA，Gate on Array)。
本发明通过将边框区域20的四个边框设计为可沿折痕框21独立折叠的形式，使得所述四个边框向显示面板100背侧弯折时，避免了显示面板100的薄膜封装结构24和电路结构的损坏，进而实现显示面板100的四边边框超窄化甚至无边框化，提高了屏占比。
将图1中显示面板100的局部放大如图2所示。在本发明实施例显示区域10的第一种实施方式中，显示区域10的四个角均设置为正圆角。由图2可知，相比与传统的显示面板中显示区域的四个角设置为直角，将本发明实施例中显示区域10的四个角设置为正圆角，使得显示区域10的边界与显示面板100转角的边界距离明显增加。显然，随着显示区域10的边界与显示面板100转角的边界距离的增加，薄膜封装结构24和显示区域10的边界距离也增加，使得显示面板100在经薄膜封装结构24封装后，有足够的距离有效防止水分和氧气进入到显示区域10内。而且将显示区域10的四个角设置为正圆角在增加显示区域10的边界与显示面板100转角的边界距离的同时也增加了电路结构走线的分布区域，使得电路结构的走线能够较容易地排布在边框区域20内。本实施例中将数据信号电路结构和栅极驱动电路结构的走线沿着显示区域10的四个正圆角分布，充分利用了增加的走线分布区域。
请参阅图3，在本发明实施例显示区域10的第二种实施方式中，与上述实施方式不同之处在于显示区域10的四个角设置为曲线，且所述四个角可以设置为不同类型或不同大小。将显示区域10的四个角设置为曲线同样可以增加显示区域10的边界距离显示面板100转角的边界距离，从而增加显示区域10的边界与薄膜封装结构24的距离，使得显示面板100经薄膜封装结构24封装后，增加的距离不仅可以增加边框区域20中电路结构走线的分布区域还可以避免外部的水分和氧气进入显示区域10损坏显示面板100，提高显示面板100的可靠性。
请参阅图4，在本发明实施例显示区域10的第三种实施方式中，与上述实施方式不同之处在于显示区域10的四个角设置为倒角，且所述四个角可以 设置为不同类型或不同大小。将显示区域10的四个角设置为倒角同样可以增加显示区域10的边界与薄膜封装结构24的距离和边框区域20中电路结构走线的分布区域，防止显示面板100经折叠封装后外部的水分和氧气进入显示区域10中对显示面板100造成损伤，提高显示面板100的可靠性。
本实施例中，显示区域10的所述四个角还可以设置成不同类型或不同大小的椭圆角或椎圆角来增加显示区域10与薄膜封装结构24的距离和边框区域20中电路结构走线的分布区域，有效防止封装后的显示面板100受水分和氧气的损坏，在实现显示面板四边边框窄边框或无边框的同时提升显示面板100的可靠性。
本发明实施例中，围绕显示区域10的边框区域20的第一边框区域22位于显示区域10和折痕框21之间。第二边框区域23围绕第一边框区域22设置。第二边框区域23的转角部使第二边框区域23的四个边框分别沿折痕框21独立折叠不影响其他边框的折叠方向及轨迹。具体的，所述第二边框区域23的所述转角部包括第一边和连接第一边的第二边。复参图2，在本发明实施例中转角部的第一种实施方式中，转角部A的第一边a和第二边b均为直线边，所述第一边a的一端和第二边b的一端呈直角连接，此时第一边a和第二边b的连接处为折痕框21的顶点。
请参阅图5，在本实施例中转角部的第二种实施方式中，与上述实施方式不同之处在于，转角部B的第一边a的一端和第二边b的一端连接形成斜边或折线边，并在连接处与折痕框21折痕转角位置相交。
请参阅图6，在本实施例中转角部的第三种实施方式中，与上述实施方式不同之处在于，转角部C的第一边a和第二边b均为弧形边，所述第一边a的一端与第二边b的一端连接，此时第一边a和第二边b的连接处为折痕框21的顶点。
上述转角部的三种实施方式中第一边和第二边直接相连的设置避免了相邻边框向显示面板100背部折叠180度时发生折叠，减少了显示面板100折叠后的厚度。结合本实施例中显示区域10四个角的非直角设置，所述第一边和第二边直接连接的方式同样可以增加显示区域10的边界距离显示面板100边界的距离，从而增加显示区域10与薄膜封装结构24的距离，避免外部的水分 和氧气进入显示区域10并增加边框区域20中电路结构走线的分布区域，提高显示面板100的可靠性。
请参阅图7，在本发明本实施例中转角部的第四种实施方式中，与上述三种实施方式的不同之处在于，转角部D的第一边a和第二边b通过一连接边连接，所述连接边包括第一段和垂直设置的第二段，即所述连接边为第一边框区域22的顶角，此时折痕框21的顶角为直角，第一边a通过折痕框21的顶角与第二边连接。将图7中显示面板100的转角部D局部放大如图8所示，两相邻边框与显示区域10的距离为d 3和d 4，所述连接边中第一段和第二段的长度为d 1和d 2，显示区域10的正圆角半径为r。本实施例中为保证显示面板100的电路结构的走线空间不会减少且薄膜封装结构24的可靠性，优选d 1、d 2、d 3、d 4和正圆角半径r的距离要求满足d 3-d 1<r，d 4-d 2<r，但不局限于此。此外，本实施方式中所述第二边框区域23中四个转角部D的连接边中第一段和第二段的长度优先相等，但不局限于此。
请参阅图9，在本发明实施例中转角部的第五种实施方式中，与上述实施方式不同之处在于，所述转角部E的连接边为弧形边，包括第一端和第二端，即即所述连接边为折痕框21的顶角，此时折痕框21的顶角为圆角，所述第一边a通过折痕框21的顶角的第一端和第二端与第二边b连接。
本实施例中，所述四个转角部还可以采用不同大小或不同类型的连接边。所述第一边和第二边通过连接边连接的方式使得第二边框区域23的所述四个边框相对于折痕框21的所述四条折痕内缩，不仅可以减少所述四个边框沿折痕框21弯折时的弯折应力，还可以确保所述四个边框可以在预设的折痕处进行准确的弯折。结合本实施例中显示区域10四个角的非直角设置，所述第一边和第二边通过连接边连接的方式进一步增加显示区域10的边界距离显示面板100边界的距离，从而增加显示区域10与薄膜封装结构24的距离，避免外部的水分和氧气进入显示区域10并增加边框区域20中电路结构走线的分布区域，提高显示面板100的可靠性。
本发明实施例中，转角部所在的第二边框区域23中的四个边框可分别沿折痕框21向显示面板100的背部独立折叠。如图10所示，图10为本实施例中第二边框区域23中的所述四个边框沿折痕框21折叠90度后的结构示意图。 由图10可知，采用独特的显示区域设计可实现显示面板的四边边框超窄化，提高屏占比。其中，第二边框区域23中的四个边框可分别沿折痕框21向显示面板100的背部折叠任意角度来满足显示面板100的不同需求，优选为折叠90度或180度
本发明所述显示面板采用特殊的显示区域设计和在边框区域内的电路结构进行特殊布线的方式，不仅可以满足足够电路结构的走线空间，防止水分和氧气进入显示面板中，还实现了显示面板的四边边框超窄化甚至无边框化，大大提高了显示区域的屏占比。
本发明还提供一种显示装置，所述显示装置包括上述显示器。所述显示装置可以为：主动发光显示面板(OLED，Organic Light Emitting Diode)、手机、平板电脑、电视机、显示器等具有显示功能的产品或部件。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
