 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发明的一些实施例，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是本发明柔性触控屏结构的平面示意图；
图2是图1中A-A的横截面图；
图3是图1中B-B的横截面图；
图4A至图4C是本发明无机线路层的各种断面示意图；及
图5是本发明柔性触控屏的制作方法的方块流程图。
 本发明的最佳实施方式
在具体实施方式中提及“实施例”意指结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的不同位置出现的相同用语并非必然被限制为相同的实施方式，而应当理解为与其它实施例互为独立的或备选的实施方式。在本发明提供的实施例所公开的技术方案启示下，本领域的普通技术人员应理解本发明所描述的实施例可具有其他符合本发明构思的技术方案结合或变化。
请参照图1所示，图1为本发明柔性触控屏结构的平面示意图。如1图所示，本发明提供一种柔性触控屏结构1，包括基板11、图案层2及驱动芯片3。如图所示的基板11为玻璃、聚乙烯(PET)、聚甲基丙烯酸甲酯(polymethyl methacrylate；PMMA)、环烯烃聚合物(cyclo olefin polymer；COP)、聚酰亚胺（polyimide；PI）等基底材料。当基板11使用硬质玻璃时，本发明的触控屏也能够应用在硬质触控屏中。然而在其他不同的实施例中，所述基板11也可以是薄膜晶体管液晶显示器(TFT-LCD)、低温多晶硅有机发光二极管(LTPS-OLED)、等离子（即电浆）或激光显示（LDT）的显示屏。
请一并参照图2所示，所述图案层2设置在所述基板11上。所述图案层2包括多个发射电极22(Tx)和多个接收电极21(Rx)，各所述发射电极22和各所述接收电极21相互间隔且交叉设置。驱动芯片3设置在所述基板11的一端，也就是底端。
所述驱动芯片3包括至少一缺陷探测线31和多根导电线路35。所述至少一缺陷探测线31间隔的围绕各所述发射电极22和各所述接收电极21且邻近所述基板11的边缘15设置。各所述导电线路35分别电性连接各所述发射电极22和各所述接收电极21。所述驱动芯片3通过量测所述至少一缺陷探测线31的电信号(图略)，所述电信号反馈所述基板11的所述边缘15是否存在缺陷(裂纹、破损等)，从而达到快速检测柔性触控屏1的边缘15是否具有缺陷的效果。
具体而言，当所述基板11的所述边缘15存在缺陷而延伸至所述缺陷探测线31时，通过量测所述缺陷探测线31的电信号，例如电流、电阻等发生改变，即能够得知所述柔性触控屏1的边缘15是否存在缺陷，以进行必要维护处理。
请一并参照图3所示，还包括设置在所述基板11上的无机线路层4，所述无机线路层4邻设于所述至少一缺陷探测线31的一侧且远离所述边缘15设置。所述至少一缺陷探测线31的数量优选为2个，例如第一缺陷探测线32和第二缺陷探测线33。所述第一缺陷探测线32和所述第二缺陷探测线33分别布设于所述无机线路层4的两侧且电性连接所述驱动芯片3。所述第一缺陷探测线32、所述第二缺陷探测线33和所述无机线路层4分别包围各所述发射电极22和各所述接收电极21。
所述第一缺陷探测线32和所述第二缺陷探测线33并未连接任何所述发射电极22和任何所述接收电极21，且所述第一缺陷探测线32和所述第二缺陷探测线33的材质与各所述导电线路35相同，例如金、铜、铁或其合金。
请一并参考图4A至图4C所示，图4A的所述无机线路层4例如为单一实心线路；图4B的所述无机线路层4为多条并列的梯状线路，在如图4B下方的图示为其横截面图；图4C的所述无机线路层4为多个彼此交错的方块状线路。根据上述不同的线路结构，将所述无机线路层4分段或分块强化效果更佳；然而从制作简易程度来看，所述无机线路层4为单一实线更容易制作，视实际需要而改变。因此，通过设置在所述第一缺陷探测线32和所述第二缺陷探测线33之间的无机线路层4，会对基板11具有强化结构的作用，也就是说，所述无机线路层4在柔性触控屏结构1上能够防止缺陷进一步的向内延伸。
此外，如图1至图3的实施例中，还包括设置在所述基板11的绝缘层12和设置在所述绝缘层12上的保护层13。所述图案层2则包括设置在所述绝缘层12上的多个桥接金属23。各所述桥接金属23横跨各所述接收电极21以电性连接任二相邻接的所述发射电极22。所述保护层13例如为玻璃、防刮柔性薄膜或其他适合的盖板。如图2所示，各所述发射电极22和各所述接收电极21同层设置。有关本实施例的图案层2仅以图2为例作说明，但并不以此为限。
请一并参照图5所示，本发明还提供一种柔性触控屏结构1的制作方法，包括以下步骤:步骤S10，提供基板11。步骤S20、在所述基板11上形成图案层2，所述图案层2包括形成有多个发射电极22(Tx)、多个接收电极21(Rx)、至少一缺陷探测线31和多根导电线路35，各所述发射电极22和各所述接收电极21相互间隔且彼此交叉，所述至少一缺陷探测线31形成在各所述发射电极22和各所述接收电极31外围且邻近所述基板11的边缘15，各所述导电线路35分别电性连接各所述发射电极22和各所述接收电极21。
步骤S30，在所述基板11的一端形成所述驱动芯片3，所述驱动芯片3电性连接各所述发射电极22(Tx)、各所述接收电极21(Rx)、所述至少一缺陷探测线31和多根导电线路35。当所述驱动芯片通过量测所述至少一缺陷探测线31的电信号时，所述电信号反馈所述基板11的所述边缘15是否存在缺陷。
在步骤S20中，还包括形成在所述基板11上的无机线路层4，所述无机线路层4形成于所述至少一缺陷探测线31的一侧且远离所述边缘15设置。所述至少一缺陷探测线31的数量为2个，例如第一缺陷探测线32和第二缺陷探测线33，各所述缺陷探测线31分别形成在所述无机线路层4两侧且电性连接所述驱动芯片3，各所述缺陷探测线31和所述无机线路层4分别包围各所述发射电极22和各所述接收电极21。
具体而言，当所述基板11的所述边缘15存在缺陷而延伸至所述缺陷探测线31时，通过量测所述缺陷探测线31的电信号，例如电流、电阻等发生改变，即能够得知所述柔性触控屏1的边缘15是否存在缺陷，以进行必要维护处理。通过设置在所述第一缺陷探测线32和所述第二缺陷探测线33之间的无机线路层4，会对基板11具有强化结构的作用，也就是说，所述无机线路层4在柔性触控屏结构1上能够防止缺陷进一步的向内延伸。若对所述第二缺陷探测线33进行加电压量测时，如果电信号正常，则能够立刻得知缺陷并未延伸到基板11内部；反之，若所述电信号异常，则柔性触控屏1损坏率提高。因此通过本发明的所述缺陷探测陷31的设计，有效掌握柔性触控屏1品管品质，达到品质提升与降低成本的效果，同时减少产品变异对造成客户端的品质风险。
在形成所述图案层2前，还包括形成在所述基板11的绝缘层12和形成在所述绝缘层12上的保护层13。所述图案层则包括形成在所述绝缘层12上的多个桥接金属23，各所述桥接金属23横跨各所述接收电极21以电性连接任二相邻接的所述发射电极22。在步骤S30中，所述至少一缺陷探测线31、各所述导电线路35和所述驱动芯片3优选为同一制程且同层制成。
再者，所述无机线路层4例如为单一实心线路、多条并列的梯状线路或多个彼此交错的方块状线路，视需要而改变。所述基板11则为玻璃、聚乙烯(PET)、聚甲基丙烯酸甲酯(polymethyl methacrylate；PMMA)、环烯烃聚合物(cyclo olefin polymer；COP)、聚酰亚胺（polyimide；PI）或为TFT-LCD、LTPS-OLED的显示屏。所述保护层13例如为玻璃、防刮柔性薄膜或其他适合的盖板。
综上所述，虽然本发明结合其具体实施例而被描述，应该理解的是，许多替代、修改及变化对于那些本领域的技术人员将是显而易见的。因此，其意在包含落入所附权利要求书的范围内的所有替代、修改及变化。
