Description

一种触控屏中引线的制作方法、触控屏及电子设备 技术领域
本发明涉及触控感测技术领域，尤其涉及一种触控屏中引线的制作方法、触控屏及电子设备。
背景技术
随着触控技术和移动终端技术的发展，越来越多的移动终端采用触控方式进行人机交互。触控屏除了可以用手指直接触控操作以外，还可以通过主动笔或者被动笔替代手指进行触控输入操作。主动笔的原理是触控屏通过耦合电容接收主动笔发送的信号。
触控屏根据手指、主动笔或者被动笔的触控操作，产生触控信息并感测具体的触控位置。触控屏通常包括具有感应通道和/或驱动通道的显示区域(VA，View Area)以及具有感应通道引线和/或驱动通道引线的非显示区域，显示区域用于被所述手指、主动笔或者被动笔触发产生触控信息；非显示区域则不应被所述手指、主动笔或者被动笔触发产生触控信息。主动笔触发所述触控屏的非显示区域的感应通道引线和/或驱动通道引线，而造成显示区域冒点(感应通道和/或驱动通道被误触发)的概率大于手指或者被动笔。
因此，如何避免非显示区域的走线被触发成为现有技术中亟需解决的技术问题。
发明内容
有鉴于此，本发明提供一种触控屏中引线的制作方法、触控屏及电子设备，其减少了感应通道引线和/或驱动通道引线的走线宽度,避免了由此造成的所述触控屏的误触发。
本发明提供一种触控屏中引线的制作方法，包括：对所述触控屏的ITO通道图案引线所在的区域进行整体印刷；采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。
本发明还提供一种触控屏，所述触控屏包括传输接触位置信号的感应通道 引线和/或驱动通道引线，所述感应通道引线和/或驱动通道引线为对所述触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。
本发明还提供一种电子设备，包括：如上述任一种的触控屏。
由以上技术方案可见，本发明实施例对触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。因此，本发明实施例减少了感应通道引线和/或驱动通道引线的走线宽度。当主动笔接触到非显示区域时接触到感应通道引线和/或驱动通道引线的机会减少，因此在显示区域发生冒点的风险降低，避免了由此造成的所述触控屏的误触发。

具体实施方式
参见图1a和图1b，触控屏的感应通道引线和/或驱动通道引线11经过采用常规镭射印刷工艺(例如，GFF镭射印刷工艺)制作后形成感应通道引线和/或驱动通道引线12，通常因为印刷工艺限制，感应通道引线和/或驱动通道引线的走线宽度做得比较大，且具有大面积的金属通道的残留。在采用主动笔操作触控屏时，主动笔对所述触控屏的非显示区域进行点击，由于感应通道引线和/或驱动通道引线的走线宽度大，而主动笔点击到所述感应通道引线和/或驱动通道引线，造成在显示区域发生触控位置的误触发，从而出现冒点的现象，影响触控屏的用户使用体验。
本发明实施例对触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。因此，本发明实施例减少了感应通道引线和/或驱动通道引线的走线宽度。当主动笔接触到非显示区域时接触到感应通道引线和/或驱动通道引线的机会减少，因此在显示区域发生冒点的风险降低，避免了由此造成的所述触控屏的误触发。
当然，实施本发明的任一技术方案必不一定需要同时达到以上的所有优点。
为了使本领域的人员更好地理解本发明中的技术方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于本发明保护的范围。
下面结合本发明附图进一步说明本发明具体实现。
实施例一
本发明实施例提供一种基于主动笔应用的触控屏中引线的制作方法。
参见图2，所述方法包括：
步骤S101、对所述触控屏的ITO通道图案引线所在的区域进行整体印刷。
具体地，所述触控屏为GFF(Glass+Film+Film)结构触控屏。但本发明并 不局限于GFF(Glass+Film+Film)结构触控屏，本发明可应用于所有采用激光镭射工艺制作的触控屏中。
在本发明实施例一具体实现中，所述步骤S101具体为：
对所述触控屏的ITO通道图案引线所在的区域采用银浆进行整体印刷。
参见图1b，由于现有的GFF镭射工艺对于触控屏的ITO通道图案引线分别进行镭射印刷处理，则会造成感应通道引线和/或驱动通道引线12的走线宽度过大，尤其是走线拐角部分的宽度过大。
参见图3，本发明实施例对触控屏的ITO通道图案引线所在的区域31采用银浆进行整体印刷，即并不是仅如图1b仅针对通道图案引线12部分分别进行镭射印刷处理。
具体地，所述银浆由银或其化合物、助熔剂、粘合剂和稀释剂配制而成。
步骤S102、采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。
所述预设阈值为本领域技术人员根据所述激光工艺镭射所能够达到的最小值进行设定。
具体地，所述预设阈值为0.1mm。从而实现所述感应通道引线和/或驱动通道引线小于采用图1b方式获得的感应通道引线和/或驱动通道引线12的走线宽度。
因此，本发明实施例能够实现令所述感应通道引线和/或驱动通道引线的走线宽度尽可能缩小，从而保证所述主动笔接触到非显示区，并不会触碰到所述感应通道引线和/或驱动通道引线。因此所述触控屏的显示区域不会因感应通道和/或驱动通道对应的感应通道引线和/或驱动通道引线被触发而发生冒点，避免了由此造成的所述触控屏的误触发。
本发明实施例对触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。因此，本发明实施例减少了感应通道引线和/或驱动通道引线的走线宽度。当主动笔接触到非显示区域时接触到感应通道引线和/或驱动通道引线的机会减少，因此在显示区域发生冒点的风险降低，避免了由此造成的所述触控屏的误触发。
实施例二
本发明实施例二除上述步骤S101——S102外，在本发明一具体实现中，参见图4，所述步骤S102包括：
S1021、采用预设的第一激光镭射图案镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。
所述第一激光镭射图案为可实现令所述走线宽度更小的激光镭射图案，例如，圆形、长方形等任意多边形。
参见图5，采用预设的第一激光镭射图案镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线51。
在本发明另一具体实现中，参见图6，所述步骤S102还包括步骤：
S1022、将所述整体印刷产生的多余的金属块打碎并分离出所述感应通道引线和/或驱动通道引线所在的区域。
本申请对所述步骤S1021和步骤S1022的前后顺序不进行限定，即本申请所述步骤S1021可以在本申请所述步骤S1022之前，本申请所述步骤S1021也可以在本申请所述步骤S1022之后。
在本发明实施例再一具体实现中，所述步骤S1022具体为：
采用预设的第二激光镭射图案将所述整体印刷产生的多余的金属块打碎并分离出所述感应通道引线和/或驱动通道引线所在区域。其示意图如图7所示，其中多余的金属块71被分离出所述感应通道引线和/或驱动通道引线所在区域，避免多余的大面积的金属块与所述感应通道引线和/或驱动通道引线连接，造成所述触控屏的误触发。
参见图8，将所述整体印刷产生的多余的金属块82打碎并分离出所述感应通道引线和/或驱动通道引线所在区域，形成的最小走线宽度的所述感应通道引线和/或驱动通道引线81，同图1b中的感应通道引线和/或驱动通道引线12相比，图8中的感应通道引线和/或驱动通道引线81的走线宽度要小得多。
本发明实施例将所述多余的大面积金属块打碎并分离出所述感应通道引线和/或驱动通道引线所在区域，打碎并分离出所述感应通道引线和/或驱动通道引线所在区域的金属小块形成悬浮金属块。所述悬浮金属块的形状可以为菱形，正方形，长方形，例如图9所示的菱形悬浮金属块91。所述悬浮金属块的形状也可以采用圆形悬浮金属块101，例如图10所示。
所述第一激光镭射图案和所述第二激光镭射图案可以为相同图案也可以为不同图案。
本申请实施例对所述悬浮金属块的形状和所述悬浮金属块的排布间隙和大小不进行限定。
本发明实施例对触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。因此，本发明实施例减少了感应通道引线和/或驱动通道引线的走线宽度。当主动笔接触到非显示区域时接触到感应通道引线和/或驱动通道引线的机会减少，因此在显示区域发生冒点的风险降低，避免了由此造成的所述触控屏的误触发。
实施例三
本发明实施例提供一种触控屏，所述触控屏包括传输接触位置信号的感应通道引线和/或驱动通道引线，所述感应通道引线和/或驱动通道引线为对所述触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。
具体地，所述触控屏为GFF(Glass+Film+Film)结构触控屏。但本发明并不局限于GFF(Glass+Film+Film)结构触控屏，本发明可应用于所有采用激光镭射工艺制作的触控屏中。
在本发明实施例一具体实现中，所述对所述触控屏的ITO通道图案引线所在的区域进行整体印刷具体为：
采用银浆对所述触控屏的ITO通道图案引线所在的区域进行整体印刷。
参见图1b，由于现有的GFF镭射工艺对于触控屏的ITO通道图案引线分别进行镭射印刷处理，则会造成感应通道引线和/或驱动通道引线12的走线宽度过大，尤其是走线拐角部分的宽度过大。
参见图3，本发明实施例对触控屏的ITO通道图案引线所在的区域31采用银浆进行整体印刷，即并不是仅如图1b仅针对通道图案引线12部分分别进行镭射印刷处理。
具体地，所述银浆由银或其化合物、助熔剂、粘合剂和稀释剂配制而成。

具体地，所述预设阈值为0.1mm。从而实现所述感应通道引线和/或驱动通道引线小于采用图1b方式获得的感应通道引线和/或驱动通道引线12的走线宽 度。
因此，本发明实施例能够实现令所述感应通道引线和/或驱动通道引线的走线宽度尽可能缩小，从而保证所述主动笔接触到非显示区，并不会触碰到所述感应通道引线和/或驱动通道引线。因此所述触控屏的显示区域不会因感应通道和/或驱动通道对应的感应通道引线和/或驱动通道引线被触发而发生冒点，避免了由此造成的所述触控屏的误触发。
本发明实施例对触控屏的ITO通道图案引线所在的区域进行整体印刷，并采用激光工艺镭射出走线宽度小于预设阈值的感应通道引线和/或驱动通道引线，所述预设阈值为根据所述激光工艺镭射所能够达到的最小值进行设定。因此，本发明实施例减少了感应通道引线和/或驱动通道引线的走线宽度。当主动笔接触到非显示区域时接触到感应通道引线和/或驱动通道引线的机会减少，因此在显示区域发生冒点的风险降低，避免了由此造成的所述触控屏的误触发。

至此，已经对本主题的特定实施例进行了描述。其它实施例在所附权利要求书的范围内。在一些情况下，在权利要求书中记载的动作可以按照不同的顺序来执行并且仍然可以实现期望的结果。另外，在附图中描绘的过程不一定要求示出的特定顺序或者连续顺序，以实现期望的结果。在某些实施方式中，多任务处理和并行处理可以是有利的。
在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序 开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
上述实施例阐明的系统、装置、模块或单元，具体可以由计算机芯片或实体实现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可以为个人计算机、膝上型计算机、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
为了描述的方便，描述以上装置时以功能分为各种单元分别描述。当然，在实施本申请时可以把各单元的功能在同一个或多个软件和/或硬件中实现。
本领域内的技术人员应明白，本申请的实施例可提供为方法、系统、或计 算机程序产品。因此，本申请可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本申请可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。

这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
在一个典型的配置中，计算设备包括一个或多个处理器(CPU)、输入/输出接口、网络接口和内存。
内存可能包括计算机可读介质中的非永久性存储器，随机存取存储器(RAM)和/或非易失性内存等形式，如只读存储器(ROM)或闪存(flash RAM)。内存是计算机可读介质的示例。

还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
