 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本申请实施例提供的显示面板结构示意图；
图2为图1中A区域的放大示意图；
图3为本申请实施例提供的另一种显示面板的局部结构示意图。
 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。
本申请针对现有的显示面板，在进行镭射切割时产生的热辐射易对切割线附近的显示面板的结构造成影响的技术问题，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结构示意图。所述显示面板1包括：位于所述显示面板1上的切割线2，以及分别位于所述切割线2两侧的有效区10和无效区11，所述显示面板1沿所述切割线2进行镭射切割，所述无效区11用于切除，以使所述显示面板1的四角区域及上边框的“美人尖”位置形成倒角；净空区3，至少分布于所述切割线2的一侧，所述显示面板1对应所述净空区3的位置设置有凹槽（未标示），所述凹槽用于隔绝镭射切割时的热量传导。
如图2所示，为图1中A区域的放大示意图。此处仅以所述显示面板1的A区域为例进行说明，可以理解的是，所述显示面板的四角区域与所述A区域一致。所述净空区3位于所述切割线2的两侧，所述显示面板还包括切割识别标记4，所述切割识别标记4沿所述切割线2的延伸方向间隔分布，起到标记的作用。其中，所述无效区11的膜层上设置有导热金属层5，所述导热金属层5延伸至所述净空区3的边缘位置。所述导热金属层5具有导热速度快的特点，在所述显示面板进行镭射切割的过程中，切割产生的热辐射大多数被所述导热金属层5吸收，从而增加镭射热辐射向所述切割线2一侧的所述无效区11中传导的速率，进而减少热辐射向所述有效区10一侧传递，提高所述显示面板镭射切割的信赖性。
在一种实施例中，所述净空区3的延伸方向与所述切割线2的延伸方向一致。所述净空区3的宽度大于所述切割线2的宽度。
在一种实施例中，所述净空区3位于所述有效区10一侧的宽度大于等于位于所述无效区11一侧的宽度。由于所述有效区10一侧的所述净空区3的宽度较大，因此，进一步减小了镭射热辐射向所述有效区10一侧传递。
所述导热金属层5布满所述无效区11，其中，所述导热金属层5对应所述无效区11可以为整面设计；另外，也可以如图中所示，所述导热金属层5间隔的分布于所述无效区11内。所述导热金属层5可以呈条状分布，或者呈块状分布；其中，所述导热金属层5靠近所述切割线2一侧的分布密度大于远离所述切割线2一侧的分布密度；或者，所述导热金属层5靠近所述切割线2一侧的面积大于远离所述切割线2一侧的面积。当然，所述导热金属层5还可以为其他规则或不规则的形状，此处不做限定。
所述显示面板包括层叠设置的无机/有机膜层，所述凹槽对应所述净空区3设置，所述凹槽至少贯穿部分所述无机/有机膜层。所述无机/有机膜层包括缓冲层、栅绝缘层、间绝缘层、钝化层、平坦层、像素定义层中的一者或一者以上。其中，所述凹槽的深度可根据实际制程而确定，此处不做限定。
所述显示面板包括薄膜晶体管，所述导热金属层5在所述薄膜晶体管的制程中形成。例如，在所述薄膜晶体管的栅极制备的过程中，栅极金属层在对应所述无效区11的位置同时形成所述导热金属层5；或者，在所述薄膜晶体管的源漏极制备的过程中，源漏金属层在对应所述无效区11的位置同时形成所述导热金属层5。
在一种实施例中，所述无效区11内包括至少两层所述导热金属层5。比如，在形成所述薄膜晶体管的所述栅极和所述源漏极的过程中，分别在所述无效区11对应的位置形成层叠设置的所述导热金属层5。此设计可进一步加快镭射热辐射向所述无效区11一侧的传递速度，可进一步提高所述显示面板镭射切割的信赖性。所述导热金属层5还可以为所述显示面板中的其他能够快速导热的金属膜层制备。
如图3所示，为本申请实施例提供的另一种显示面板的局部结构示意图。与图2相比，图3中的无效区11内不设置所述导热金属层，而是将所述净空区3设置于所述切割线2靠近所述有效区10的一侧，通过调整所述净空区3与所述切割线2的相对位置，将所述净空区3移至所述切割线2的内侧，所述切割线2外侧无所述净空区3设计，热辐射能量可通过所述显示面板的膜层大部分导入外围的所述无效区11的切割废料中，而内侧有所述净空区3，可大幅度降低辐射热辐射传导至有所述效区域10内。在图中，所述切割识别标记4的设计与图2中的设计一致，均沿所述切割线2间隔分布。
在一种实施例中，在上述图3的基础上，所述无效区11内设置有所述导热金属层5，所述导热金属层5靠近所述切割线2设置。其中，所述导热金属层5的设置与上述图2中的描述一致，此处不再赘述。此设计可进一步加快镭射热辐射向所述切割线2外侧的所述无效区11中传导的速率。
综上所述，本申请提供的显示面板，通过对切割线附近的显示面板进行变更设计，即调整净空区与切割线的相对位置，将净空区设置于有效区一侧，使得热辐射能量通过介质膜层大部分导入外围的无效区中；或者通过在切割线外的无效区中添加辅助设计的导热金属层，增加镭射热辐射向切割线外的无效区中传导的速率；从而进一步降低镭射热辐射对显示面板的影响，提高显示面板的信耐性。
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。
