以下将参照相关图式，说明依本申请较佳实施例的触控显示装置，其中相同的组件将以相同的参照符号加以说明。
图1A为本申请的触控显示装置的一实施例的示意图。图1B为本申请的触控显示装置的一实施例的剖视示意图。在图1A与图1B中，一第一基板1包括一基板11、多条行导线12、多条列导线13、多个单位像素14、一导电保护线路15、一区域16、及一区域17。行导线12及列导线13交错形成一像素矩阵DM，单位像素14设置在像素矩阵DM内。第一基板1例如是有源矩阵基板。
基板11例如是绝缘透光基板，材料可以是刚性材料或是可挠曲材料，例如玻璃或塑料等。
导电保护线路15在制造过程中先与多条行导线12、多条列导线13连接，导电保护线路15布设在第一基板1上的像素矩阵DM外侧，因而在制造过程中作为短路布线可以提供静电保护功能，藉以将行导线12、列导线13电连接，使每个导线的电位相等，可消除静电导致液晶显示面板的损坏。
导电保护线路15可以和行导线12与列导线13一起制作，举例来说，导电保护线路15的区段151是和行导线12一起形成在基板11上，导电保护线路15的区段152是和列导线13一起形成在基板11上，区段151和区段152连接。由于行导线及列导线通常是金属导线，导电保护线路15也是金属导线。
区域16及区域17可以设置连接导线的导线驱动器，例如区域16设置行驱动器，行驱动器连接行导线12并输出行驱动信号到行导线12，区域17设置列驱动器，列驱动器连接列导线13并输出列驱动信号到列导线13。或者是区域16及区域17没有直接设置驱动器，而是设有用来连接导线驱动器的线路或连接垫，区域16的线路或连接垫连接行导线12，区域17的线路或连接垫连接列导线13，行驱动器及列驱动器透过扁平电缆或电路板等分别电性连接区域16以及区域17，因而分别电性连接行导 线12及列导线13，并能够分别输出行驱动信号及列驱动信号到行导线12及列导线13。
举例来说，行导线12是扫描线，包括多条扫描线S1～Sm，行驱动器是扫描驱动电路，行驱动信号是扫描驱动信号。列导线是数据线，包括多条数据线D1～Dn，列驱动器是数据驱动电路，列驱动信号是数据驱动信号。数据线D1～Dn与扫描线S1～Sm交错设置以定义出多个单位像素14。
在图1A中，导电保护线路15是沿第一基板1上的边缘设置。例如区段151沿平行于行导线12的边缘设置，区段152沿平行于列导线13的边缘设置。行导线12的相对二端分别连接导电保护线路15及区域16，列导线13的相对二端分别连接导电保护线路15及区域17。
以行驱动器设置在区域16来说，行驱动器连接行导线12，位在第一基板1上未有导电保护线路15的一侧，行驱动器电连接在第一基板1上未有导电保护线路15的一侧的行导线12。以列驱动器设置在区域17来说，列驱动器连接列导线13，位在第一基板1上未有导电保护线路15的一侧，列驱动器电连接在第一基板11上未有导电保护线路15的一侧的列导线13。行驱动器和列驱动器位在第一基板1上的不同侧。
另一方面，以行驱动器未直接设置在区域16来说，行驱动器电连接在第一基板1上未有导电保护线路15的一侧的行导线12。以列驱动器未直接设置在区域17来说，列驱动器电连接在第一基板11上未有导电保护线路15的一侧的列导线13。
图1C为本申请的单位像素的一实施例的示意图。如图1C所示，单位像素14的像素驱动组件包括一薄膜晶体管141以及一像素电容142。薄膜晶体管141作为开关用，闸极连接行导线12，源极连接列导线13，汲极连接像素电容142。行导线12上的扫描驱动信号可控制薄膜晶体管141导通，藉以让列导线13上的数据驱动信号写入像素电容142。
像素电容142是液晶电容，由二个电极构成。一般来说，液晶电容包括像素电极与共同电极，薄膜晶体管141的汲极则连接像素电极，共同电极连接一共同电压(Vcom)。在一些实施例中，共同电压的电压值可为0伏特(接地)。当薄膜晶体管141的闸极被行导线12施加一扫描 驱动信号而导通时，列导线13上的数据驱动信号的数据电压便透过薄膜晶体管141施加于像素电极，使像素电极与共同电极间产生一电压差，液晶电容储存数据驱动信号写入的电位差，以驱动两电极间的液晶分子转动。
像素电极与共同电极的材料可例如但不限于为铟锡氧化物(indium-tin oxide,ITO)或铟锌氧化物(indium-zinc oxide,IZO)等透明导电材料。
像素电极与共同电极的配置因不同类型显示面板有所差异，以横向电场效应显示面板来说，像素电极与共同电极皆形成在第一基板1，也就是与薄膜晶体管141形成在同一个基板11上，在这架构下，对向基板可以不用形成一整片的共通电极，因而较有空间形成触控电极。以多象限垂直配向面板或扭曲向列型面板来说，对向基板上形成一整片的共通电极，像素电极与薄膜晶体管141皆形成在第一基板1，第一基板1上的像素电极与对向基板上的共通电极构成液晶电容。
图1C是举例说明一般单位像素的基本组件，故只举出一个薄膜晶体管141以及一个像素电容142。在其他实施态样中，单位像素还可以包括多个薄膜晶体管和其他电容组件。在一实施例中，在各像素中更可具有一储存电极(未显示)，其可与第二电极形成一辅助电容。
回到图1A，导电保护线路15位在第一基板1上区域16和区域17的相对侧，导电保护线路15是短路布线的一部分，短路布线用于使行导线12的端部和列导线13的端部短路，以防止静电损伤显示面板，例如薄膜晶体管5的击穿和特征缺陷。
导电保护线路15与行导线12和列导线13要断开，液晶面板才能正常运作，将导电保护线路15从行导线12和列导线13可利用激光束沿图1所示的交替的长短虚线或虚线外侧断开。导电保护线路15是在第一基板1上原与行导线12与列导线13所连接的一短路布线经裁切后留存的部分。
由于导电保护线路15与行导线12和列导线13被切断后，液晶显示面板再次面临静电引起的问题，例如组件击穿和组件击穿引起的特性缺陷。为了避免此问题，在触控显示装置中，可将导电保护线路15与触控 电极电连接。
图2A为本申请的触控显示装置的一实施例的侧视示意图。图2B为本申请的触控显示装置的一实施例的侧视示意图。如图2A与图2B所示，导电保护线路15距离行导线12或列导线13一段距离，触控显示装置包括第一基板1、一第二基板2、一显示介质3及一密封件4。第二基板2与第一基板1相对而设。若使用横向电场效应显示的技術，显示介质3、第一基板1与第二基板2作为一横向电场效应显示面板。
显示介质3夹设在第一基板1与第二基板2的内侧间，显示介质3例如是液晶。密封件4夹设在第一基板1与所述第二基板2的内侧间，位在像素矩阵DM与导电保护线路15间，密封显示介质3。
第二基板2包括一基板21以及多个触控电极22，触控电极22形成在基板21上。导电保护线路15与触控电极22电连接。
另外，第二基板2可设有滤光层(图未出示)，第一基板1与第二基板2有配向膜等组件(图未出示)。
在图2A中，触控显示装置更包括一导电组件5，导电组件5夹设在所述第一基板1与所述第二基板2的内侧间，连接导电保护线路15与所述触控电极22的一延伸部23。导电保护线路15与所述触控电极22间的电连接是透过设置在第一基板1与第二基板2间的导电组件5。导电组件5可以直接接触导电保护线路15与所述触控电极22。
在图2B中，触控显示装置更包括一导电线路6，导电线路6位在第一基板1与第二基板2外，连接导电保护线路15与触控电极22的一延伸部23。导电保护线路15与所述触控电极22间的电连接是透过设置在第一基板1与第二基板2外的导电线路6，导电线路6可以透过连接线接触导电保护线路15与所述触控电极22。
在图2A与图2B的架构下，行导线12和列导线13能够单独操作。由于本液晶显示面板利用短路剩余线作为保护布线，所以可以省略形成防护布线的步骤。此外，将具有短路布线的常规基板作为第一基板1并将短路剩余线与第二基板2上的触控电极22电连接，导电保护线路15仍可以防止外部静电对显示面板引起的损坏。
在图3A中，导电控制组件7包括串接偏压配置相反的二个二极管 71、72电性连接在导电保护线路15及触控电极22间。二极管71、72位在第一基板1与第二基板2外，连接导电保护线路15与触控电极22的一延伸部23。导电保护线路15与所述触控电极22间的电连接是透过设置在第一基板1与第二基板2外的二极管71、72，二极管71、72可以透过连接线接触导电保护线路15与所述触控电极22。
在一般运作情况下，因二极管72逆偏于触控电极22，因此触控电极22上的信号不会传送到导电保护线路15。因二极管71逆偏于导电保护线路15，因此导电保护线路15上的小噪声也不会传送到触控电极22，使得触控电极22能独立运作。
当有静电产生的时后，因瞬间的电压会大于二极管71、72的逆偏压，因此二极管71、72会导通使得导电保护线路15和触控电极22电性连接，导电保护线路15可以防止外部静电对显示面板的像素引起的损坏。
在图3B中，导电控制组件7包括一切换开关73，选择性地将触控电极22电性连接至导电保护线路15或一触控电路81，切换开关73位在第一基板1与第二基板2外，连接导电保护线路15与触控电极22的延伸部23。导电保护线路15与所述触控电极22间的电连接是透过设置在第一基板1与第二基板2外的切换开关73，切换开关73可以透过连接线接触导电保护线路15与所述触控电极22。
一控制电路82控制切换开关73要电连接导电保护线路15或触控电路81。在一般运作情况下，控制电路82控制切换开关73，使触控电极22电连接到触控电路81，藉以进行常规的触控功能。在有静电产生的情况下，控制电路82控制切换开关73，使触控电极22电连接到导电保护线路15，藉以进行静电防护功能。
举例来说，控制电路82可采分时的方式切换触控电极22电连接的目标。例如每隔一段时间将切换开关73从触控电路81切到导电保护线路15，同时让触控电路81不进行触控功能以防受到导电保护线路15与触控电极22上的静电伤害；每隔一段时间再将切换开关73从导电保护线路15切到触控电路81，同时再让触控电路81与触控电极22进行触控功能，由于切换开关73没有让触控电极22与导电保护线路15电连接，导电保护线路15上的小噪声也不会传送到触控电极22，使得触控电极 22能独立运作。
控制电路82例如是显示面板中的控制器，触控电路81例如是触控侦测电路或是触控激励电路。
在图3A与图3B的架构下，行导线12和列导线13能够单独操作，触控电极22也能单独操作。由于本液晶显示面板利用短路剩余线作为保护布线，所以可以省略形成防护布线的步骤。此外，将具有短路布线的常规基板作为第一基板1并将短路剩余线与第二基板2上的触控电极22电连接，导电保护线路15仍可以防止外部静电对显示面板引起的损坏。
图4A为本申请的导电保护线路的电连接位置的示意图。如图4A所示，导电保护线路15的区段151直接作为端子连接图2A中的导电组件5。在第二基板2上触控电极22有对应的延伸部23作为端子连接图2A中的导电组件5，藉以实现电连接。另外，图4A只是以平行于行导线12的区段151为例，区段152也可以直接作为端子连接图4A中的导电组件5，并且在第二基板2上触控电极22有对应的延伸部23作为端子连接图2A中的导电组件5，藉以实现电连接。

另外，在图4B中，端部153或另一端部可作为端子电连接图2B中的导电线路6，在第二基板2上触控电极22有对应的延伸部23作为端子电连接到图2B中的导电线路6，藉以实现电连接。
另外，在图4B中，导电保护线路15的区段151延伸到端部153，端部153作为端子也可电连接图3A或图3B中的导电控制组件7，在第二基板2上触控电极22有对应的延伸部23作为端子电连接图3A或图3B中的导电控制组件7，藉以实现电连接。另外，图4B只是以平行于行 导线12的区段151为例，区段152也可以延伸到另一端部，另一端部位在区域17旁，另一端部作为端子电连接图3A或图3B中的导电控制组件7，并且在第二基板2上触控电极22有对应的延伸部23作为端子电连接图3A或图3B中的导电控制组件7，藉以实现电连接。

另外，触控电极22也可以彼此不相连接，各延伸部23分别连接触控电极22。
另外，图5A与图5B是举例说明触控电极22的排列方式，并非限定触控电极22的形状，一般触控电极22的单位形状是菱形。
在图5A与图5B中，区域24及区域25可以设置连接触控电极22的触控电路。或者是区域24及区域25没有直接设置触控电路，而是设有用来连接触控电路的线路或连接垫，触控电路透过扁平电缆或电路板等电性连接区域24以及区域25。
在图5A中，触控电极22是触控显示装置的部分触控电极，触控显示装置的另一部分的触控电极设置在第一基板1上。触控电极22可以是侦测电极或是激励电极。触控电极22有多行R1-Rx。

综上所述，本申请的触控显示装置中，导电保护线路与所述行导线及所述列导线电性隔离，与所述触控电极电性连接，因而可保护像素驱动组件防止受到静电引起的问题。

在图6A与图6B的架构下，行导线12和列导线13能够单独操作，触控电极22a、92也能单独操作。由于本液晶显示面板利用短路剩余线作为保护布线，所以可以省略形成防护布线的步骤。此外，将具有短路布线的常规基板作为第一基板1a并将短路剩余线与第二基板2a外侧的触控电极22a、92电连接，导电保护线路15仍可以防止外部静电对显示面板引起的损坏。
图7A至图7D为本申请的触控显示装置的一实施例的侧视示意图。如图7A至图7D所示，导电保护线路15距离行导线12或列导线13一段距离，触控显示装置包括第一基板1a、一第二基板2a、一显示介质3及一密封件4。第二基板2a与第一基板1a相对而设。

触控显示装置更包括一导电控制组件7，导电控制组件7位在第一基板1a与第二基板2a外，连接导电保护线路15与触控电极的一延伸部。导电保护线路15与所述触控电极间的电连接是透过设置在第一基板1a与第二基板2a外的导电控制组件7，导电控制组件7可以透过连接线接触导电保护线路15与触控电极。

在一般运作情况下，因二极管72逆偏于触控电极22a，因此触控电极22a上的信号不会传送到导电保护线路15。因二极管71逆偏于导电保护线路15，因此导电保护线路15上的小噪声也不会传送到触控电极22a， 使得触控电极22a能独立运作。
当有静电产生的时后，因瞬间的电压会大于二极管71、72的逆偏压，因此二极管71、72会导通使得导电保护线路15和触控电极22a电性连接，导电保护线路15可以防止外部静电对显示面板的像素引起的损坏。

控制电路82例如是显示面板中的控制器，触控电路81例如是触控侦测电路或是触控激励电路。
如图7C所示，由于图7C的导电控制组件7与图7A的导电控制组件7相同或类似，故相关的电路特性及运作可参考前述图7A的相关说明，故此不再坠述。
如图7D所示，由于图7D的导电控制组件7与图7B的导电控制组件7相同或类似，故相关的电路特性及运作可参考前述图7B的相关说明， 故此不再坠述。
在图7A至图7D的架构下，行导线12和列导线13能够单独操作，触控电极22a、92也能单独操作。由于本液晶显示面板利用短路剩余线作为保护布线，所以可以省略形成防护布线的步骤。此外，将具有短路布线的常规基板作为第一基板1a并将短路剩余线与第二基板2a外侧的触控电极22a、92电连接，导电保护线路15仍可以防止外部静电对显示面板引起的损坏。

综上所述，本申请的触控显示装置中，导电保护线路与所述行导线及所述列导线电性隔离，与所述触控电极电性连接，因而可保护像素驱动组件防止受到静电引起的问题。

第二基板2b包括一基板21以及多个触控电极22，触控电极22形成在基板21上。经裁切后留存的短路布线15与触控电极22电连接。
另外，第二基板2b可设有滤光层(图未出示)，第一基板1b与第二基板2b有配向膜等组件(图未出示)。
在图8A中，触控显示装置可包括一导电线路，导电线路位在第一基板1b与第二基板2b外，连接经裁切后留存的短路布线15与触控电极22。经裁切后留存的短路布线15与所述触控电极22间的电连接是透过设置在第一基板1b与第二基板2b外的导电线路，导电线路可以透过连接线 接触经裁切后留存的短路布线15与所述触控电极22。经裁切后留存的短路布线15与所述触控电极22间的电连接是提供制造过程时的静电防护保护。
在图8A的架构下，由于本液晶显示面板利用短路剩余线作为保护布线，所以可以省略形成防护布线的步骤。此外，将具有短路布线的常规基板作为第一基板1b并将短路剩余线与第二基板2b上的触控电极22电连接，经裁切后留存的短路布线15仍可以防止外部静电对显示面板引起的损坏。
然后，如图图8B所示，经裁切后留存的短路布线15与所述触控电极22间的电连接被移除，经裁切后留存的短路布线15改作为天线，电连接一通讯控制电路83。针对会留存的短路布线可以设计有天线图案，以利无线电的传输。这样可以有效利用短路布线15。
本实施例的组件也可以参考如图1A至图7D的实施例子中相同或对应标号的组件说明，故此不再坠述。
综上所述，本申请的触控显示装置中，经裁切后留存的短路布线与所述行导线及所述列导线电性隔离，与所述触控电极电性连接，因而可保护像素驱动组件防止受到静电引起的问题。
另外，在以上的实施例中，行导线12、列导线13、单位像素14、导电保护线路15、区域16、及区域17位在第一基板1的正面，第一基板1的区域16及区域17可以透过扁平电缆或电路板等分别电性行驱动器及列驱动器，行驱动器及列驱动器可以设置在第一基板1的背面，这种配置有利于窄边框的显示装置。
除了第一基板1的背面设置行驱动器及列驱动器外，为了有利于窄边框的显示装置，还可以去除部分的导电保护线路15，以省去部分导电保护线路15在第一基板1上所占的空间。举例来说，如图9A所示，导电保护线路15仅设置在行导线12的一端，在列导线13的二端未设有导电保护线路15；如图9B所示，导电保护线路15仅设置在列导线13的一端，在行导线12的二端未设有导电保护线路15。图9A及图9B关于导电保护线路15的变化也可应用在以上的实施例。省去部分导电保护线路15的作法可以是在裁切短路布线时，将不想留存的部分短路布线裁切 掉，剩下的短路布线作为导电保护线路15。
另外，在以上的实施例中，导电保护线路15可位在基板的侧边。举例来说，如图10所示，行导线12、列导线13、单位像素14、区域16、及区域17位在第一基板1的正面，导电保护线路15位在基板11的侧边，导电保护线路15包括二区段15A、15B分别位在基板11的不同侧边111、112。基板11的另外二个侧边可以不设有导电保护线路15，侧边111、112也未由导电保护线路15全部填满。
区段15A、15B是彼此连接，导电保护线路15例如是导电胶带黏在侧边111、112上，或是用L型金属板框在基板的侧边111、112上。
另外，第一基板1的区域16及区域17也可以透过扁平电缆或电路板等分别电性行驱动器及列驱动器，行驱动器及列驱动器可以设置在第一基板1的背面，这种配置有利于窄边框的显示装置。
以上内容是结合具体的优选实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
