随着全面屏的发展，为了提高屏占比，需要减小显示屏的下边界的宽度，如图1所示，现有玻璃衬底芯片 (chip on glass，COG)模组包括衬底基板10、显示区域11、位于显示区域11下方的驱动芯片20以及柔性电路板（FPC）30；其中下边框的尺寸由FPC绑定区的宽度a、柔性电路板至FPC之间的宽度（WOA区宽度）b、驱动芯片20的宽度c以及数据线的扇出线的宽度d组成。
然而，这种显示面板结构的边框尺寸比较大，因此出现了图2所示的结构。图2中的显示面板的下边框尺寸主要由数据线的扇出线的宽度d、驱动芯片20的宽度c组成，结合图3，柔性电路板30的输出端子31通过连接线32与驱动芯片20的引脚21连接。
 技术问题
虽然有效地减小了下边框的宽度，然而，连接线（WOA走线）32的长度较长，该连接线32包括两个竖直部和水平部，导致连接线的阻抗较大。且随着驱动芯片引脚的增多，越靠近IC内侧的引脚对应的连接线的阻抗越大，从而增大了信号的衰减以及功耗。

本发明提供一种显示面板，其包括显示区域和绑定区域，所述绑定区域设置有多个第二输入端子，多个所述第二输入端子位于所述绑定区域的两侧，至少其中一侧的各第二输入端子与所述绑定区域的下边缘的距离不同，所述第二输入端子用于将柔性电路板绑定在所述显示面板上。
本发明还提供一种显示装置，其包括上述显示面板。

请参照图4至8，图4为本发明显示面板的结构示意图。
本发明的柔性电路板40用于连接驱动芯片20和电路板（图中未示出）。
柔性电路板40包括：两个第一输出部41和第一输入部42，所述第一输入部42和所述第一输出部41分别设置于柔性电路板的不同侧。其中第一输入部41包括多个第一输入端子（图中未示出）。当然可以理解的，所述输出部41的数量不限于两个。
第一输出部41设于所述第一输入部42上，所述第一输出部41与所述第一输入部42电性连接，其中两个所述第一输出部41分别位于所述柔性电路板40的相对两侧；结合图5，其中所述第一输出部41包括多个第一输出端子，至少其中一个所述第一输出部41中各第一输出端子43与所述第一输出部41的顶端之间的距离不同。比如从左至右，第一输出端子43与第一输出部的顶端之间的距离依次为h1至h6，h1至h6各不相等。当然，h1至h6的高度只要不同即可，并不需要规律性变化。
如图5或6所示，其中为了进一步减小连接线的长度，沿预设方向上，其中一个所述第一输出部41中的第一输出端子43与所述第一输出部41的顶端（M点）之间的距离逐渐增大。该预设方向可以为从左至右或者从右至左的方向。比如，在一实施方式中，在沿所述驱动芯片20的几何中心向两侧延伸的方向上，其中一个或者两个所述第一输出部41的高度逐渐增大。比如从中间至左方向上，所述第一输出部41的高度逐渐增大，从中间至右方向上，所述第一输出部41的高度也逐渐增大。第一输出端子43设置在第一输出部41的顶端，此外，还可以简化制程工艺，降低生产成本。
所述第一输出部41与所述第一输入部42电性连接。结合图5至8，其中所述第一输出部41通过多条连接线50与所述驱动芯片20连接。
在一实施方式中，为了简化制程工艺，所述第一输出部41的形状为直角梯形，所述第一输出部41的顶边44相对于水平线倾斜设置。其中左侧的第一输出部41与水平线之间的夹角为钝角，右侧的第一输出部41与水平线之间的夹角为锐角。其中所述第一输出部41的侧边与所述第一输出部41的底边之间垂直，所述第一输出部41的顶边44与所述第一输出部41的侧边之间倾斜。当然，可以理解的，所述第一输出部41的形状不限于直角梯形，还可以为其他形状。
其中，为了进一步减小连接线的长度，所述第一输出部41包括多个第一输出端子43，其中多个第一输出端子43平行设置。
且所述第一输出端子43的顶边（最上方的边）与所述第一输出部41的顶边44抵接。为了进一步减小连接线的长度，在一实施方式中，多个所述第一输出端子43位于所述第一输出部41的顶端。比如，所述第一输出端子的顶边与所述第一输出部41的顶边44抵接，可以省去靠近柔性电路板侧的竖直方向的连接线。可以理解的，所述第一输出部41的顶边44的形状可以为弧形或者其它形状，第一输出端子43的顶边的形状可以为弧形或者其它形状。
为了提高连接的稳定性，所述第一输出端子43的顶边与所述第一输出部41的顶边44平行。如图5至8所示，在一实施方式中，所述第一输出端子43的形状为直角梯形或者长方形。当然，所述第一输出端子43的形状也可为其他形状。
为了进一步减小连接线的阻抗，所述第一输入端子与所述第一输出端子43之间通过走线连接，所述走线的材料包括铜、金以及银中的至少一种。其中所述第一输入端子与所述第一输出端子43对应。
可以理解的，位于驱动芯片20的右侧的第一输出部41的结构与左侧的第一输出部41的结构相同，在一实施方式中，两者相对于竖直线对称设置，在此不再赘述。当然可以理解的，位于驱动芯片20右侧的第一输出部41的结构还可与图2中的相同。
由于对现有的柔性电路板的结构进行改进，具体是将至少一输出部中的输出端子与所述第一输出部的顶端之间的距离不同，因此可以省去了靠近柔性电路板侧的竖直方向的连接线，因而减小了连接线的长度，从而降低了连接线的阻抗，进而减小连接线的功耗以及降低信号的衰减。
返回图4，本发明还提供一种显示面板包括显示区域11和绑定区域101，所述绑定区域101设置有多个第二输入端子（图中未示出），多个所述第二输入端子位于所述绑定区域101的两侧，至少其中一侧的各第二输入端子与所述绑定区域的下边缘的距离不同，所述第二输入端子用于将柔性电路板40绑定在所述显示面板上。所述柔性电路板40为上述任意一种柔性电路板。当然，所述第一输出部41的最大高度不能超过绑定区域101的顶端。
此外显示面板还可包括：驱动芯片20，还可包括衬底基板10，显示区域11、驱动芯片20以及柔性电路板40均设于衬底基板10上。
其中显示区域11包括多条数据线和扫描线，驱动芯片20与所述显示区域11电性连接，比如驱动芯片20与显示区域11的数据线连接。结合图5至8，驱动芯片20包括多个引脚21。所述引脚21通过连接线50与所述第一输出端子43连接。第一输出端子43的数量与引脚21的数量匹配。驱动芯片20还可包括接入端子，所述接入端子靠近显示区域侧，所述接入端子与所述数据线连接。
两个所述第一输出部41设于所述驱动芯片20的两侧，具体位于所述引脚21的两侧。
如图5至7所示，所述连接线50包括彼此连接的水平部51和竖直部52。其中水平部51的另一端与第一输出端子43连接。竖直部52的另一端与引脚21连接。在一实施方式中，所述连接线50的形状为倒L形。在部分实施例中，连接线50和基板上的绑定端子可以分布在不同的金属层，例如图6中连接线50形成在绑定端子之下的金属层，通过通孔换线至绑定端子所在的金属层，避免连接线之间在用于柔性电路板的绑定端子处发生短路。
如图8所示，所述连接线50可相对于水平线倾斜设置。
其中，为了进一步降低功耗以及减小高频信号的衰减，所述连接线50的阻抗大于所述柔性电路板40中走线的阻抗。在一实施方式中，所述连接线50的截面结构包括Mo、Al以及Mo，所述柔性电路板40中走线的材料包括铜、金以及银中的至少一种。
本发明还提供一种显示装置，其包括上述显示面板。所述显示装置可包括背光模块。
本发明的柔性电路板、显示面板及装置，其中柔性电路板包括第一输入部；至少一个第一输出部，设于所述第一输入部上，所述第一输出部与所述第一输入部电性连接，所述第一输入部和所述第一输出部分别设置于柔性电路板的不同侧；其中所述第一输出部包括多个第一输出端子，至少其中一个所述第一输出部中各第一输出端子与所述第一输出部的顶端之间的距离不同；由于至少一输出部中的各第一输出端子与所述第一输出部的顶端之间的距离不同，因此减小了连接线的长度，从而降低了连接线的阻抗，进而减小了连接线的功耗以及降低了信号的衰减。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
