本申请主张在2014年11月21日在中国提交的中国专利申请号No.201410676885.7的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及触摸技术领域，特别是指一种触摸显示面板及触摸显示装置。
背景技术
目前市场上的触摸屏包括外挂式触摸屏和集成触摸屏，集成触摸屏是在生产液晶显示面板的同时把触摸板集成进去。集成触摸屏的集成方式有两种，一种是将触摸板的功能集成在液晶显示面板的彩膜基板上方(也称为on-cell集成方式)，另一种是将触摸板的功能集成在液晶显示面板的彩膜基板和阵列基板之间(也称为in-cell集成方式)。
on-cell集成方式是常用的一种集成方式，为了不影响触摸显示面板的透过率，现有技术中在彩膜基板朝向阵列基板的一侧采用透明导电层制作发射电极，并在彩膜基板的另一侧采用透明导电层制作接收电极。但是由于发射电极位于彩膜基板内侧，触摸信号可能会干扰液晶偏转，影响触摸显示面板的显示效果。另外薄膜晶体管上的信号也会与触摸信号相互干扰，降低触摸显示面板的灵敏度；并且对于共用公共电极模式的显示面板来说，存在公共电极信号和触摸信号分时复用的问题；而且对于TN(扭曲向列性)显示面板来说，位于彩膜侧的透明导电层会屏蔽Touch(触摸)信号；同时，由于透明导电层的电阻率较高，采用透明导电层来制作发射电极和接收电极，会使得触摸显示面板的负载较大，灵敏度进一步降低。
发明内容

下面结合附图以及具体的实施例对本公开的触摸显示面板进行进一步地介绍：
实施例一
现有技术采用透明导电层在彩膜基板内侧制作发射电极，导致触摸信号可能会干扰液晶偏转，影响触摸显示面板的显示效果。另外薄膜晶体管上的信号也会与触摸信号相互干扰，降低触摸显示面板的灵敏度；并且对于利用共用的公共电极(请确认此处的修改是否正确？)制作发射电极的显示面板来说，存在公共电极信号和触摸信号分时复用的问题，导致公共电极信号和触摸信号扫描时间不够，无法实现产品的大尺寸和高PPI(每英寸像素数)。同时，由于透明导电层的电阻率较高，采用透明导电层来制作发射电极和接收电极，会使得触摸显示面板的负载较大，灵敏度进一步降低，为了减少负载，需要加宽外围引线，不利于产品的窄边框化，只适合做小尺寸的触摸显示面板。
为了解决上述问题，本实施例提供了一种触摸显示面板。如图1所示，本实施例的触摸显示面板包括彩膜基板、阵列基板、彩膜基板和阵列基板之间的液晶层，彩膜基板包括第一衬底基板3，阵列基板包括第二衬底基板7，第一衬底基板3和第二衬底基板7上分别贴附有偏光片1和偏光片8，彩膜基板和阵列基板之间通过封框胶9封装在一起。
其中，第一衬底基板3背离阵列基板的一侧设置有多个相互平行、由透明导电层形成的第二电极，第二电极位于第一衬底基板3和偏光片1之间；在第一衬底基板3朝向阵列基板的一侧设置有多个相互平行、由金属制成的第一电极，第一电极在垂直于第一衬底基板3方向上的投影完全落入黑矩阵4中，本实施例中，第一电极为发射电极5，第二电极为接收电极2。本实施例利用黑矩阵4不透光的原理，采用不透光的金属制作发射电极5，发射电极5在垂直于第一衬底基板3方向上的投影落入黑矩阵4中，这样发射电极5并不影响触摸显示面板的透光率。具体地，可以采用Mo、Al、Cu或Ag等导电性能较好的金属制作发射电极5，可以降低触摸显示面板的负载，进而降低触摸显示面板的功耗，提高触摸显示面板的灵敏度；同时能够减小外围 引线的宽度，利于产品的窄边框化及实现大尺寸的触摸显示面板。
其中，发射电极5可以设置在黑矩阵4和第一衬底基板3之间，还可以设置在黑矩阵4远离第一衬底基板的一侧上。如果发射电极5设置在黑矩阵4和第一衬底基板3之间，由于金属一般都会反光，则发射电极5可能会影响触摸显示面板的显示效果，因此，优选将发射电极5设置在黑矩阵远离第一衬底基板的一侧上。
进一步地，触摸显示面板还包括设置在发射电极5和液晶层之间的透明屏蔽层6，透明屏蔽层6可以采用透明导电层制成，透明屏蔽层6可以屏蔽触摸信号对液晶偏转的影响，保证触摸显示面板的显示效果，该透明屏蔽层还可以屏蔽薄膜晶体管上信号和触摸信号之间的相互干扰，保证触摸显示面板的灵敏度。另外，对于利用共用的公共电极制作发射电极的触摸显示面板来说，还解决了公共电极信号和触摸信号分时复用的问题，进而能够使TN模式的触摸显示面板实现大尺寸和产品高PPI。
本实施例中，在黑矩阵4限定出的像素区域内还形成有第二平坦层16，在第二平坦层16上形成有彩色滤光层14，在彩色滤光层14上形成有第一平坦层15，透明屏蔽层6位于第一平坦层15上。即第一衬底基板3背离液晶层的一侧依次形成有接收电极2和偏光片1；第一衬底基板3朝向液晶层的一侧依次形成黑矩阵4、发射电极5、第二平坦层16、彩色滤光层14、第一平坦层15和透明屏蔽层6。
其中，如图2和图3所示，发射电极5可以设计成如10所示的条状，通过发射电极外围走线11与外部电路连接；接收电极2可以设计成如12所示的菱形，通过接收电极外围走线13与外部电路连接，进一步地，接收电极2还可以设计成条状或网状。
在制作本实施例的触摸显示面板时，可以先在第一衬底基板3上依次形成黑矩阵4、发射电极5、第二平坦层16、彩色滤光层14、第一平坦层15、透明屏蔽层6和隔垫物，之后与制作好的阵列基板进行对盒，再在第一衬底基板3背离阵列基板的一侧形成接收电极2，最后在彩膜基板和阵列基板上贴附偏光片，形成触摸显示面板。
进一步地，还可以在第一衬底基板3的一侧形成接收电极2，再在第一 衬底基板3的另一侧依次形成黑矩阵4、发射电极5、第二平坦层16、彩色滤光层14、第一平坦层15、透明屏蔽层6和隔垫物，之后与制作好的阵列基板进行对盒，最后在彩膜基板和阵列基板上贴附偏光片，形成触摸显示面板。
实施例二
现有技术采用透明导电层在彩膜基板内侧制作发射电极，导致触摸信号可能会干扰液晶偏转，影响触摸显示面板的显示效果。另外薄膜晶体管上的信号也会与触摸信号相互干扰，降低触摸显示面板的灵敏度；并且对于利用共用公共电极制作发射电极的显示面板来说，存在公共电极信号和触摸信号分时复用的问题，导致公共电极信号和触摸信号扫描时间不够，无法实现产品的大尺寸和高PPI。同时，由于透明导电层的电阻率较高，采用透明导电层来制作发射电极和接收电极，会使得触摸显示面板的负载较大，灵敏度进一步降低，为了减少负载，需要加宽外围引线，不利于产品的窄边框化，只适合做小尺寸的触摸显示面板。
为了解决上述问题，本实施例提供了一种触摸显示面板。如图4所示，本实施例的触摸显示面板包括彩膜基板、阵列基板、彩膜基板和阵列基板之间的液晶层，彩膜基板包括第一衬底基板3，阵列基板包括第二衬底基板7，第一衬底基板3和第二衬底基板7上分别贴附有偏光片1和偏光片8，彩膜基板和阵列基板之间通过封框胶9封装在一起。
其中，第一衬底基板3背离阵列基板的一侧设置有多个相互平行、由透明导电层形成的第二电极，第二电极位于第一衬底基板3和偏光片1之间；在第一衬底基板3朝向阵列基板的一侧设置有多个相互平行、由金属制成的第一电极，第一电极在垂直于第一衬底基板3方向上的投影完全落入黑矩阵4中，本实施例中，第一电极为发射电极5，第二电极为接收电极2。本实施例利用黑矩阵4不透光的原理，采用不透光的金属制作发射电极5，发射电极5在垂直于第一衬底基板3方向上的投影落入黑矩阵4中，这样发射电极5并不影响触摸显示面板的透光率。具体地，可以采用Mo、Al、Cu或Ag等导电性能较好的金属制作发射电极5，可以降低触摸显示面板的负载，进而降低触摸显示面板的功耗，提高触摸显示面板的灵敏度；同时能够减小外围引线的宽度，利于产品的窄边框化及实现大尺寸的触摸显示面板。
其中，发射电极5可以设置在黑矩阵4和第一衬底基板3之间，还可以设置在黑矩阵4远离第一衬底基板的一侧上。如果发射电极5设置在黑矩阵4和第一衬底基板3之间，由于金属一般都会反光，则发射电极5可能会影响触摸显示面板的显示效果，因此，对金属采用消影工艺制作或尽量窄细化以达到人眼不可视的程度。
进一步地，触摸显示面板还包括设置在发射电极5和液晶层之间的透明屏蔽层6，透明屏蔽层6可以采用透明导电层制成，透明屏蔽层6可以屏蔽触摸信号对液晶偏转的影响，保证触摸显示面板的显示效果，该透明屏蔽层还可以屏蔽薄膜晶体管上信号和触摸信号之间的相互干扰，保证触摸显示面板的灵敏度。另外，对于利用共用的公共电极制作发射电极的触摸显示面板来说，还解决了公共电极信号和触摸信号分时复用的问题，进而能够使TN模式的触摸显示面板实现大尺寸和产品高PPI。
本实施例中，在黑矩阵4限定出的像素区域内形成有彩色滤光层14，在彩色滤光层14上形成有第一平坦层15，透明屏蔽层6位于第一平坦层15上。即第一衬底基板3背离液晶层的一侧依次形成有接收电极2和偏光片1；第一衬底基板3朝向液晶层的一侧依次形成黑矩阵4、发射电极5、彩色滤光层14、第一平坦层15和透明屏蔽层6。
其中，如图2和图3所示，发射电极5可以设计成如10所示的条状，通过发射电极外围走线11与外部电路连接；接收电极2可以设计成如12所示的菱形，通过接收电极外围走线13与外部电路连接，进一步地，接收电极2还可以设计成条状或网状。
在制作本实施例的触摸显示面板时，可以先在第一衬底基板3上依次形成黑矩阵4、发射电极5、彩色滤光层14、第一平坦层15、透明屏蔽层6和隔垫物，之后与制作好的阵列基板进行对盒，再在第一衬底基板3背离阵列基板的一侧形成接收电极2，最后在彩膜基板和阵列基板上贴附偏光片，形成触摸显示面板。
进一步地，还可以在第一衬底基板3的一侧形成接收电极2，再在第一衬底基板3的另一侧依次形成黑矩阵4、发射电极5、彩色滤光层14、第一平坦层15、透明屏蔽层6和隔垫物，之后与制作好的阵列基板进行对盒，最 后在彩膜基板和阵列基板上贴附偏光片，形成触摸显示面板。
以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
