本申请针对现有技术的显示面板，存在显示面板的下边框较宽，不利于实现窄边框发展的技术问题，本实施例能够解决该缺陷。
如图1所示，为本申请实施例提供的显示面板未绑定前的结构示意图。所述显示面板1包括显示区2以及外围的边框区3，所述边框区3设有绑定区31和走线区32；所述走线区32包括位于所述显示区2相对两侧的第一走线区321，和位于所述显示区2另外一侧的第二走线区322，以及所述第一走线区321与所述第二走线区322的交叉位置靠近所述显示区2一侧的走线预留区323，所述第二走线区322位于所述显示区2与所述绑定区31之间。实际生产中，只要不影响布线，所述绑定区31可以与所述走线区32的部分区域形成重叠，以合理利用所述边框区3的空间。另外，图中为了方便示意，将所述走线预留区323与所述第一走线区321以及所述第二走线区322隔开用以区分，实际生产中，所述走线预留区323与所述第一走线区321以及所述第二走线区322相互连通。
结合图2所示，为本申请实施例提供的显示面板绑定后的结构示意图。所述显示面板包括薄膜晶体管层（未标示）、像素单元层（未标示）以及触控层4等其他常规膜层。所述显示面板的触控方式可以为面内触控或者是外挂式触控。本实施例仅以所述触控层4为互容式触控为例进行说明，当然并不限制于此。
所述触控层4对应所述显示区2设置，包括相互交叉且绝缘设置的第一电极链41与第二电极链42。所述第一电极链41在与所述第二电极链42交叉的位置断开，并通过过桥411将触控电极412电连接，所述第二电极链42包括相互连接的感应电极421。所述触控电极412与所述感应电极421之间形成电容，用以实现触控功能。
在所述边框区3的走线区32内设置有连接所述触控层4与柔性电路板5的触控走线6。所述触控走线6包括设于所述第一走线区321并连接所述第一电极链41的第一走线61，和设于所述第二走线区322并连接所述第二电极链42的第二走线62。一所述第一走线61对应连接一所述第一电极链41，一所述第二走线62对应连接一所述第二电极链42。
在一种实施例中，所述第一走线61均匀的布设于所述显示区2两侧的所述第一走线区321内。
所述柔性电路板5对应所述绑定区31绑定于所述显示面板上，所述柔性电路板5呈分段式设计，包括设置有引线的引线区51。所述引线区51又包括位于所述引线区51两端的第一引线区511和中间的第二引线区512。其中，所述第一引线区511在对应所述第一走线区321与所述第二走线区322的交叉位置呈预设倾斜角设置，并且所述第一引线区511朝所述走线预留区323一侧倾斜设置。所述第二引线区512与所述第二走线区322水平设置。即所述引线区51向所述显示区2一侧呈弧形或弯折状设置。所述第一走线61沿所述第一走线区321经由所述走线预留区323与所述第一引线区511电连接，所述第二走线62沿所述第二走线区322布设并与所述第二引线区512电连接。由于连接所述第一电极链41的所述第一走线61不用通过所述第二走线区322就能实现与所述柔性电路板5的连接，从而大大减小显示面板的下边框宽度，实现窄边框。
在一种实施例中，所述第一引线区511的所述预设倾斜角在0°~90°之间。即所述第一引线区511与所述第二引线区512可以位于同一水平线上；或者，所述第一引线区511远离所述第二引线区512的一端向所述显示区一侧靠近，比如所述预设倾斜角呈30°、45°、60°设置。
在所述触控层4制备的过程中，至少在所述触控层4对应所述第二走线区322的两侧边角处切除一部分，形成所述走线预留区323；即可以将对应所述第一走线区321与所述第二走线区322交叉位置的所述触控电极412和/或所述感应电极421切除一部分形成所述走线预留区323；或者所述触控电极412和/或所述感应电极421避开所述走线预留区323设计。
所述触控层4与所述走线预留区323相邻部分的边界与所述走线预留区323的边界相匹配。所述触控层4的所述第一电极链41和/或所述第二电极链42与所述走线预留区323相邻部分的边界线为弧线、直线或者折线及其组合等。
在一种实施例中，所述第一引线区511与所述触控层4之间的宽度大于等于所述第一走线区321的宽度。即所述第一走线61可以完全布设于所述走线预留区323内与所述第一引线区511连接；或者一部分所述第一走线61布设于所述走线预留区323内，另外一部分所述第一走线61直接在所述第一走线区321内与所述第一引线区511连接。
所述第一走线61位于所述走线预留区323的部分与相邻所述第一电极链41和/或所述第二电极链42的边界线平行。即所述第一走线61经过所述走线预留区323时，可以沿着此处的所述第一电极链41或所述第二电极链42的边界线排布，比如可以呈直线、曲线或折线等方式排布。
在一种实施例中，所述第一引线区511靠近所述走线预留区323一侧的边界线与所述第一电极链41和/或所述第二电极链42对应所述走线预留区323的边界线一致。
在一种实施例中，所述柔性电路板5包括至少两所述第二引线区512，所述第二走线62分别与至少两所述第二引线区512电连接。由于具有多个所述第二引线区512，可以减少所述第二走线62由于聚集在一起而占用的空间，因此，可以进一步实现窄边框化。
本申请提供的显示面板，通过在第一走线区与第二走线区的交叉位置的内侧设置走线预留区，即触控层的电极在该交叉位置处切除一部分而设置该走线预留区；且柔性电路板采用分段设计且在对应该交叉位置倾斜设置；从而使得连接触控电极的第一走线不用通过第二走线区就能实现与柔性电路板的连接，从而有效减小显示面板的下边框宽度，实现窄边框。
综上所述，虽然本申请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申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
