Description

显示面板及其显示装置 技术领域
本发明涉及显示领域，尤其涉及一种显示面板及其显示装置。
 背景技术
在设计柔性显示面板时，为了防止外界的应力进入功能区域而破坏功能性线路，通常会在线路的最外围加入防裂纹线路（Anti-Crack线）；尤其是目前生产工艺中的玻璃切割工艺下，切割显示面板时在面板周边会产生外力，当外力进入面板时，防裂纹线路最先承受应力，当外部应力过大时，防裂纹线路会断裂，阻断外力进入面板内部；避免内部功能性线路受到外力产生断裂。
为了避免上述外力产生断裂风险，在面板的四周设置防裂纹线路结构，起到了阻断裂纹扩展的作用，但也带来新的问题。
如图1所示,为现有面板的防裂纹线路结构示意图，由于防裂纹线路91为大块金属，呈栅栏型相互连接环绕面板，其阻抗较低，且距离切割道92较近，易吸引电荷；故对产品进行静电测试时，防裂纹线路91较容易炸伤并且将电荷传到至面板内部的工作线路93，造成面板无法正常工作。
因此，有必要提供一种新的显示面板及显示装置，以克服现有技术存在的问题。
 技术问题
本发明的目的在于，提供一种显示面板及显示装置，本发明防裂纹线路可保证阻断外力进入面板内部，并且防止防裂纹线路电荷积累过多造成静电测试时面板内部的工作线路炸伤，从而保护显示面板边缘走线的完整性，避免走线断裂而造成面板异常。
 技术解决方案
为了解决上述问题，本发明提供一种显示面板包括功能区和围绕所述功能区的外围区；其中，在所述功能区设置有一外围工作线路，所述外围工作线路邻近于所述外围区；所述外围区包括围绕所述功能区的防裂纹线路，所述防裂纹线路包括多个沿所述功能区侧边的延伸方向平行排列的阻挡条，每个所述阻挡条上具有间隔设置的凸起结构。
进一步的，其中所述凸起结构呈三角形。
进一步的，其中所述凸起结构半圆形。
进一步的，其中所述凸起结构成对设置于所述阻挡条两侧。
进一步的，其中所述凸起结构设置于所述阻挡条上远离所述功能区的一侧。
进一步的，其中所述凸起结构等距离间隔排布。
进一步的，其中所述阻挡条等距离间隔排布。
进一步的，其中所述阻挡条及所述凸起结构的材料为金属。
进一步的，其中所述外围工作线路包括外围信号线或环形检测线。
本发明还提供一种显示装置，包括以上所述的显示面板。
 有益效果
本发明的有益效果在于：提供一种显示面板及显示装置，通过设置防裂纹线路可保证阻断外力进入面板内部，并且防止防裂纹线路上设置凸起结构用于聚集电荷，电荷积累过多造成静电测试时仅炸伤所述防裂纹线路，可进一步提高电阻，从而提高所述防裂纹线路的静电防护能力。即使电荷积累也不会影响面板内部的工作线路，从而保护显示面板边缘走线的完整性，避免走线断裂造成面板异常。

在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。

本实施例将从显示面板的角度进行描述，该显示面板可以集成在显示装置中，显示装置可以包括手机、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
实施例1
请参阅图2-图4所示，本发明第一实施例提供一种显示面板100，包括功能区10和围绕所述功能区10的外围区20；其中，在所述功能区10设置有外围工作线路30，所述外围工作线路30邻近于所述外围区20；所述外围区20包括围绕所述功能区10的防裂纹线路40，所述防裂纹线路40包括多个沿所述功能区10侧边的延伸方向平行排列的阻挡条1，每个所述阻挡条1上具有间隔设置的凸起结构2。
在显示面板100静电测试时，由于尖端放电的原理，所述凸起结构2用于聚集电荷，电荷会聚集在凸起结构2附近，凸起结构2附近容易炸伤；由于所述防裂纹线路40无供显示面板100信号的作用，所以所述防裂纹线路40炸伤不影响显示面板100工作；炸伤后会将附近所述防裂纹线路40烧断，相当于减小金属面积，进一步提高电阻，从而提高所述防裂纹线路40的静电防护能力。
当显示面板100侧面受到垂直于该侧面外力时，所述防裂纹线路40朝向外力的表面形成与该外力接触的接触面，当所述防裂纹线路40为直线型线段时，由于所述防裂纹线路40与该外力垂直其受力最大。
根据力学知识易知，当所述防裂纹线路40具有所述凸起结构2时，所述防裂纹线路40朝向外力的接触面为与外力不垂直的表面，即外力方向与所述防裂纹线路40的接触面不垂直，则外力施加于所述防裂纹线路40的所述凸起结构2时，外力分解为与所述凸起结构2的接触面垂直的一个垂直分离和与接触面平行的一个平行分力，且由力学知识易知，这两个分力均小于该外力，则所述防裂纹线路40的所述凸起结构2将该外力分解为比该外力小且朝向其他方向的两个分力，可以在显示基板切割、取放或转移过程中缓解产生裂纹的状况，如果外力过大，即，将施加的外力分解之后形成的分力仍然可以达到显示面板100产生裂纹的临界应力，由于所述防裂纹线路40具有所述凸起结构2，在显示面板100平面内，沿所述防裂纹线路40的延伸方向，即沿与所述防裂纹线路40的排列方向垂直的方向，在相同的直线距离内，具有所述凸起结构2的所述防裂纹线路40实际长度较长，裂纹在扩展的过程中会有能量消耗，所述防裂纹线路40可以有效阻止裂纹的扩展，使裂纹在显示面板100平面内的发展的直线距离很短。
因此，本发明提出具有所述凸起结构2的所述防裂纹线路40，所述凸起结构2用来进一步阻止裂纹的扩展。
请参阅图3所示，本实施例中，所述凸起结构2呈三角形。
请参阅图4所示，为图3中的所述防裂纹线路40的受力分析示意图，由于所述凸起结构2呈三角形，其外侧面为斜面，与施加于侧边的外力F不垂直，可以将该外力F分解，可以将该外力F分解，将该外力F分解为朝向其他方向且均小于该外力的两个分力F1、F2，可以有效缓解在显示面板100切割、取放或转移过程中产生裂纹的状况，且多个述凸起结构2位于所述防裂纹线路40上，所述防裂纹线路40的实际长度较长，可以有效阻止裂纹的扩展，使裂纹在显示面板100平面内的发展的直线距离较短，避免影响显示效果。为使形成的所述防裂纹线路40的阻挡效果更佳，可以根据实际设置在90°～120°范围内选择所述凸起结构2三角形中两个斜边所呈角度。
本实施例中，所述凸起结构2等距离间隔排布。这样排布可以均分电荷，有助于减少所述防裂纹线路40整体的静电防护能力。
本实施例中，所述阻挡条1等距离间隔排布。这样排布可以均分电荷，有助于减少所述防裂纹线路40整体的静电防护能力。
本实施例中，所述阻挡条1及所述凸起结构2的材料为金属。采用金属材料是方便制作工艺，避免生产中多次替换材料带来的时间损失。
请参阅图2所示，本实施例中，所述外围工作线路30包括外围信号线3或环形检测线4。所述外围工作线路30为显示面板100的内部功能性线路，其中外围信号线1是信号或数据传输线路，环形检测线2是检测面板电路是否良好的检测线路。
本实施例中，在显示面板100的最外围加入所述防裂纹线路40，也可保证在生产工艺中的玻璃切割工艺下，切割显示面板100时在周边产生的外力进入显示面板100时，所述防裂纹线路40最先承受应力，当外部应力过大时，所述防裂纹线路40会断裂，阻断外力进入显示面板100内部；从而能避免所述外围工作线路30受到外力产生断裂。
实施例2
请参阅图5所示，本发明第二实施例中，所述凸起结构2呈半圆形。其与第一实施例的区别在于，仅仅是所述凸起结构2由呈三角形变换为呈半圆形。
请参阅图6所示，为图5中的所述防裂纹线路40的受力分析示意图，由于所述凸起结构2呈半圆形，其外侧面为曲面，与施加于侧边的外力F不垂直，可以将该外力F分解，可以将该外力F分解，将该外力F分解为朝向其他方向且均小于该外力的两个分力F3、F4，且所述凸起结构2为弯曲状，多个述凸起结构2位于所述防裂纹线路40上，所述防裂纹线路40的实际长度较长，可以有效阻止裂纹的扩展，使裂纹在显示面板100平面内的发展的直线距离较短，避免影响显示效果。
请参阅图3、图5所示，本实施例中，所述凸起结构2成对设置于所述阻挡条1两侧。
实施例3
请参阅图7所示，在本发明第三实施例中，所述凸起结构2呈三角形，所述凸起结构2设置于所述阻挡条1上远离所述功能区10的一侧。其受力分解原理与图4相同，在此不做赘述。
实施例4
请参阅图图8所示，在本发明第三实施例中，所述凸起结构2呈半圆形，所述凸起结构2设置于所述阻挡条1上远离所述功能区10的一侧。其受力分解原理与图6相同，在此不做赘述。
当然，在其他实施例中，所述凸起结构2左右间隔设置于所述阻挡条1的两侧。其受力分解原理与图4、图6相同，在此不做赘述。
本发明还提供一种显示装置，包括以上所述的显示面板100。
本实施例提供的显示装置的工作原理，与前述显示面板100的实施例工作原理一致，具体结构关系及工作原理参见前述显示面板100实施例，此处不再赘述。
本发明的有益效果在于：提供一种显示面板及显示装置，通过设置防裂纹线路可保证阻断外力进入面板内部，并且防止防裂纹线路上设置凸起结构用于聚集电荷，电荷积累过多造成静电测试时仅炸伤所述防裂纹线路，可进一步提高电阻，从而提高所述防裂纹线路的静电防护能力。即使电荷积累也不会影响面板内部的工作线路，从而保护显示面板边缘走线的完整性，避免走线断裂造成面板异常。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
