Description

显示面板及显示器 技术领域
本发明属于显示技术领域，具体地讲，涉及一种显示面板及显示器。
背景技术
随着可穿戴应用设备如智能眼镜、智能手表等的逐渐兴起，显示行业对可挠曲显示器的需求也不断增加。有机发光二极管(Organic Light Emitting Diode，OLED)显示器具有自发光不需背光源、厚度薄、视角广、反应速度快等特点，从而具有可挠曲显示的天然优势。面对柔性OLED显示器的竞争，传统的液晶显示技术也逐渐采用柔性衬底往柔性、曲面等方向进行突破，由此可见，柔性、曲面显示的时代即将来临。
目前最新的柔性显示技术仍停留在曲面显示时代，在小尺寸领域通过在显示区域的边缘设置固定曲率半径的弧面显示区域提供视觉上更大的“全面屏”显示设备，但是仍存在曲率半径过大、外观功能大于实际功能的问题，其中关键待解决便是在小曲率半径弯曲时显示屏在光、电学方面的信赖性问题。通过实现小曲率半径的弯曲，显示装置可在显示区域的边缘以接近90°的角度弯曲，从而实现正面全面屏显示装置，同时弯曲后的显示区域可作为显示装置的侧面显示，通过赋予电源、音量、拍照、亮度调节、APP等控制图标，进一步丰富显示装置的应用可能性，这一点对于手持式显示装置尤为有利。
柔性衬底的开发使得传统的平面显示具备可挠曲的特性，为曲面显示提供了基本的硬件基础，但是现有显示技术中常用的扫描线等在弯折区、反复折叠区由于应力较大面临着信赖性的问题，这一点对于电学特性尤为重要，迫切需要需求相关的解决方法。
发明内容
为了解决上述现有技术，本发明的目的在于提供一种能够提高电学可靠性的显示面板及显示器。
根据本发明的一方面，提供了一种显示面板，其包括：平面基板以及由所述平面基板的边缘弯折形成的边框基板；扫描线，设置于所述平面基板上并延伸至所述边框基板上，所述扫描线的位于所述平面基板的边缘弯折处的部分的宽度大于所述扫描线的其他部分的宽度。
进一步地，所述显示面板还包括：阵列排布在所述平面基板上的M×N个第一像素；阵列排布在所述边框基板上的M×Q个第二像素，M、N和Q均为正整数；第N列第一像素和第1列第二像素分别位于所述平面基板的边缘弯折处的两侧，所述第二像素的沿行方向的宽度大于第1列第一像素至第N-1列第一像素中的第一像素的沿行方向的宽度，第N列第一像素中的第一像素的沿行方向的宽度大于第1列第一像素至第N-1列第一像素中的第一像素的沿行方向的宽度。

附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是根据本发明的实施例的显示面板的弯折前的状态图；
图2是根据本发明的实施例的显示面板的弯折后的状态图；
图3是根据本发明的实施例的各像素中采用的薄膜晶体管的结构示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中，为了清楚起见，夸大了层和区域的厚度。相同的标号在说明书和附图中始终用于表示相同或相近的元件。
图1是根据本发明的实施例的显示面板的弯折前的状态图。图2是根据本发明的实施例的显示面板的弯折后的状态图。
参照图1和图2，根据本发明的实施例的显示面板包括：M×N个第一像素P1、M×Q个第二像素P2、M条扫描线S1、S2……SM、N条第一数据线D1、D2……DN、Q条第二数据线D1、D2……DQ、平面基板10、边框基板20以及遮光结构30。M、N和Q均为正整数。应当说明的是，根据本发明的实施例的显示面板还可以包括其他必要的元器件。
显示面板可例如是液晶面板或者OLED显示面板，但本发明并不限制于 此。
虽然利用两个标号分别标识平面基板和边框基板，但在弯折前二者是一块整体的基板，利用两个标号仅是为了区别以及便于说明。通常而言，边框基板20是平面基板10的边缘部分。图1中虚线是弯折线(弯折处)，实际中并不存在。沿着弯折线进行弯折，使平面基板10与边框基板20垂直(即90°垂直)，这样形成曲面全面屏。当然，需要说明的是，也可以弯折呈其他角度。此外，图1中仅示出了平面基板10的一侧的边缘进行弯折，但本发明并不限制于此，例如可以根据实际需求对平面基板的两侧、三侧或者四侧进行弯折。在图2中，示出了平面基板10的相对两侧的边缘部分弯折后的状态图。
M×N个第一像素P1阵列排布在平面基板10上。M×Q个第二像素P2阵列排布在边框基板20上。
每条扫描线位于对应的同一行第一像素P1和第二像素P2的下方，但本发明并不限制于此。也就是说，每条扫描线设置于平面基板10上，且沿行方向延伸到边框基板20上。这样，每条扫描线势必横跨弯折处，为了避免扫描线在弯折处出现易短线的现象，在本实施例中，每条扫描线在弯折处被加宽，如此可以提高扫描线的抗折断能力，进而提高可靠性。
进一步地，扫描线在弯折处被加宽之后，可进一步地在扫描线的加宽部分的上方设置遮光结构30，该遮光结构30可例如是显示面板中的黑色矩阵结构，但本发明并不限制于此，这样可以防止环境光线通过加宽的扫描线形成反射而影响显示效果。遮光结构30的宽度可为10-100μm，具体依赖于弯折处的弯折曲率半径，通常较小的弯折曲率半径意味着较窄的宽度。
每条第一数据线设置于平面基板10上，并且每条第一数据线沿列方向延伸。每条第二数据线设置于边框基板20上，并且每条第二数据线沿列方向延伸。进一步地，第i列第一像素P1均连接到对应的第i条第一数据线Di，第j列第二像素P2均连接到对应的第j条第二数据线Dj，其中，1≤i≤N且1≤j≤Q。
连接第N列第一像素P1的第N条第一数据线DN位于第N列第一像素P1的远离平面基板10的边缘弯折处的一侧。连接第1列第二像素P2的第1 条第二数据线D1位于第1列第二像素P2的远离平面基板10的边缘弯折处的一侧。这样，由于各像素具有薄膜晶体管(未示出)，而薄膜晶体管连接到对应的数据线和扫描线，通过将第N条第一数据线DN和第1条第二数据线D1设置于远离弯折处，以使薄膜晶体管远离弯折处，从而避免薄膜晶体管处于弯折处而造成的驱动异常等问题。
此外，第N列第一像素P1和第1列第二像素P2分别位于弯折处的两侧，第二像素P2的沿行方向的宽度大于第1列第一像素P1至第N-1列第一像素P1中的第一像素P1的沿行方向的宽度，第N列第一像素P1中的第一像素P1的沿行方向的宽度大于第1列第一像素P1至第N-1列第一像素P1中的第一像素P1的沿行方向的宽度。如此，可使边框基板20所在的显示区的分辨率低于平面基板10所在的显示区分辨率，从一定程度上能够减少数据线及与之相关的数据驱动器驱动能力，节省制作成本。另一方面，由于边框基板20所在的显示区在功能上并非要求具有与平面基板10所在的显示区完全相同的显示能力，仅需要布置电源、音量、拍照、亮度调节、APP等拓展功能，因而对于显示分辨率的要求并不苛刻。
进一步地，第二像素P2的沿行方向的宽度等于第N列第一像素P1中的第一像素P1的沿行方向的宽度。这样，只需制作两种规格的像素即可，从而节省工序。
此外，当显示面板在显示时，第一像素P1和第二像素P2需要具有相同的存储电压。这样，无论显示面板为液晶面板还是为OLED显示面板，都能获得相同的亮度特性。
以下对各像素中采用的薄膜晶体管的结构进行简要描述。图3是根据本发明的实施例的各像素中采用的薄膜晶体管的结构示意图。
参照图3，根据本发明的实施例的各像素中采用的薄膜晶体管包括基板41、有源层42、栅极43、源极42a、漏极42b、像素电极44、公共电极45以及各绝缘层。
有源层42设置于基板41上，源极42a和漏极42b形成在有源层42的两侧。在有源层42上覆盖第一绝缘层46a。栅极43设置于第一绝缘层46a上， 在栅极43和第一绝缘层46a上覆盖第二绝缘层46b和第三绝缘层46c。在第三绝缘层46c上分别形成贯穿第二绝缘层46b、第三绝缘层46c和第一绝缘层46a的金属接触电极47a和47b，金属接触电极47a与源极42a接触，金属接触电极47b与漏极42b接触。在金属接触电极47a和47b上形成平坦层(也为绝缘)46d，在平坦层46d上形成公共电极45，在公共电极45和平坦层46d上形成间隔层(也为绝缘)46e，在间隔层46e上形成像素电极44，像素电极44贯穿间隔层46e和平坦层46d后与金属接触电极47b接触。
综上所述，根据本发明的实施例，通过在弯折处对扫描线进行加宽，从而提高扫描线在弯折处的抗折断能力，进而提升扫描线在弯折处的电学信赖性。此外，本实施例的显示面板能够实现90°小曲率半径弯曲，同时在边框显示区可实现电源、音量、拍照、亮度调节、APP等拓展功能，实现曲面全面屏显示功能，兼顾实用性与美观性。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
