Description

触摸屏拉线配置电路、显示面板及显示装置
本申请要求于2015年10月14日提交中国专利局、申请号为201510661015.7、发明名称为“触摸屏拉线配置电路、显示面板及显示装置”的中国专利申请的优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及显示领域，尤其涉及一种触摸屏拉线配置电路、显示面板及显示装置。
背景技术
触摸屏显示器(英文：Touch Screen)可以让使用者只要用手指轻轻地碰显示面板上的图符或文字就能实现对主机操作，这样摆脱了物理装置(例如：按键、鼠标等装置)的操作，使人机交互更为直截了当。主要应用于公共场所大厅信息查询、领导办公、电子游戏、点歌点菜、多媒体教学、机票、火车票预售、智能手机、智能电视和平板电脑等领域。
现有的触摸屏拉线配置电路所使用的讯号线一般使用液晶显示器(英文全称：Liquid Crystal Display,英文简称：LCD)在显示(英文：Display)的像素(英文：pixel)中使用的共通电压(英文：Voltage of common，英文简称V-com)电极，并利用V-com将触控扫描(英文全称：Touch SCAN，简称TP)讯号做空间区域讯分割，因此在面板显示上常会造成分割后的V-com的RC过大，并且RC的均匀性不好，导致面板造成闪烁(Flicker)或区域性显示器亮度不均匀，业内一般将显示器亮度不均匀称为mura。
下面结合图1来具体说明本发明所存在的缺点。
参阅图1，图1为现有技术提供的触摸屏拉线配置电路，如图1所示，其中，标号10表示触摸屏拉线配置电路的金属线(英文：metal line)，标号11表示触摸屏拉线配置电路的触控孔，标号12表示共通铟锡氧化物(英文：common indium Tin Oxide，英文简称：com ITO)，该公共铟锡氧化物在触摸屏领域的具体表现形式可以为ITO材质的透明导电膜；标号121表示被分割后 的ITO区间，如图1所示，金属线分布在com ITO上，通过触控孔10将金属线与V-com电极相连，并将集成电路(IC)的讯号传至每个ITO区间；如图1所示，由于被分割的ITO区间的位置不同，所以导致金属线经过被分割的ITO区间的个数也不一样，如图1所示，第一个ITO区间1210由于与IC离的较近，所以IC讯号传递至第一个ITO区间1210的电阻值较低，具体电阻值可以为R，为了叙述的方便，这里将单个ITO区间的电阻值标记为R；而离IC侧比较远的ITO区间，由于距离较远，例如，第五ITO区间1215，IC讯号传递至第五ITO区间1215需要穿过5个ITO区间，所以IC讯号传递至第一个ITO区间1210的电阻值较高，具体电阻值可以为5R。因此，在触摸屏的TP关闭后，触摸屏一般为显示状态，由于上述IC讯号传递至ITO区间的阻值较大，并且该阻值的分布不均匀，这样分割后的V-com的RC过大，RC分布不均匀，导致显示面板闪烁或区域性mura。

具体实施方式
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在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明具体实施方式提供的附图中两个相交的实线中如无圆点，则表示两个相交的实线未电连接，反之，下述附图中两个相交的实现中有圆点，则表示两个相交的实线电连接。
参阅图2，图2为本发明提供的第一较佳实施方式的触摸屏拉线配置电路示意图，如图2所示，该触摸屏拉线配置电路可以包括：com ITO内的ITO区间21、金属线22、触控孔23和集成电路IC；其中，在现有的触摸屏拉线配置电路增加了开关管组20，该开关管组20可以包括：多个开关管，多个开关管中每个开关管的G(栅)极均输入开关(switch)讯号，多个开关管的D(漏)极依次与金属线22的尾端连接，多个开关管的S(源)极输入至少一个电压讯号；上述switch讯号具体可以为：TP讯号未运作时处于高电平的讯号；上述电压讯号具体可以为：当触摸屏处于显示状态的V-com讯号。
在触摸屏领域，通常将靠近IC侧的一端称为首端(也可以成为头端)，将远离IC侧的一端称为尾端。上述IC的可以选用触摸显示屏的TP类的IC，具体的型号可以包括：FT5316(focal公司)的IC，当然也可以采用其他型号的IC进行替代，本发明具体实施方式并不限制上述IC的具体型号。
在触摸屏领域，TP讯号未运作具体可以包括：TP讯号未处于TP sensing(触控侦测区间)内；TP讯号未运作的区间包括但不限于：TP讯号处于LCD Display区间以及触摸屏处于前段检测区间(即IC尚未上线时)。
参阅图2，图2中的多个开关的S(源)极输入一个电压讯号，下面依据图2以及本发明第一较佳实施方式的工作原理来说明本发明第一较佳实施方式的效果，由于在尾端增加了开关管组20，当TP处于未运作时，switch讯号输出高电平，开关管组的所有开关管均导通，此时，电压讯号可以为V-com 讯号，V-com讯号可以从com ITO的首端和尾端输入到每个ITO区间；为了方便描述，这里还是将单个ITO区间的电阻设为R，则V-com讯号到每个ITO区间的电阻(为了描述的方便将V-com讯号到每个ITO区间的电阻称为R并)为并联连接的V-com讯号从首端输入到每个ITO区间的电阻和V-com讯号从尾端输入到每个ITO区间的电阻，R首表示V-com讯号从首端输入到每个ITO区间的电阻，R尾表示V-com讯号从尾端输入到每个ITO区间的电阻；以第一个ITO区间210为例，R首210＝R；R尾210＝5R，则R并210＝0.84R；以第三个ITO区间213为例，R首213＝3R；R尾213＝3R，则R并213＝1.5R；以第五个ITO区间215为例，R首215＝R；R尾215＝5R，则R并215＝0.84R；从上述计算可以看出，当采用本发明第一较佳实施方式的技术方案以后，以第一列为例，V-com讯号输入到第一列中每个ITO区间的电阻值从最大的5R降低到1.5R，最小的阻值从R降低到0.84R，所以本发明第一较佳实施方式降低了V-com讯号传递至ITO区间的阻值；另外，采用现有技术的方案中阻值的最大差值为4R，而采用本发明第一较佳实施方式的方案的阻值的最大差值为0.66R，所以本发明第一较佳实施方式的方案的阻值的均匀性好，所以本发明第一较佳实施方式能够有效的减少了显示面板闪烁或区域性mura。当TP处于运作时，即TP处于TP sensing内，此时Switch讯号输出低电平，开关管组20内的所有开关关闭，所有开关管不工作，V-com讯号也无法传递到ITO区间，这样就不会影响TP扫描。
参阅图2，由于本发明第一较佳实施方式中的switch信号在TP讯号未运行时为高电平，其不会影响触摸屏扫描，并且有效的减少了触摸屏的短路现象，因为如果在TP讯号处于TP sensing内switch信号也处于高电平时，由于switch信号处于高电平，则开关管组内所有的开关管均会开通，从而使得V-com讯号也能传递到每个ITO区间，由于TP讯号处于TP sensing内，所以当检测到触控讯号时，触控讯号也能够传递到ITO区间，此时ITO区间内有两个不同的讯号，这样很容易使得ITO区间短路(short)，所以switch信号在TP讯号未运行时为高电平能够有效的减少触摸屏的短路，降低故障率，提高安全性。
参阅图3，图3为本发明提供的第二较佳实施方式的触摸屏拉线配置电路示意图，如图3所示，该触摸屏拉线配置电路可以包括：com ITO内的ITO区 间31、金属线32、触控孔33和集成电路IC；其中，在现有的触摸屏拉线配置电路增加了开关管组30，该开关管组30可以包括：多个开关管，多个开关管中每个开关管的G(栅)极均输入开关(switch)讯号，多个开关管的D(漏)极依次与com ITO内金属线的尾端连接，多个开关管中相邻的开关管的S(源)极分别通过二条金属线32输入De电压讯号和Do电压讯号；上述switch讯号具体可以为：TP讯号未运作时处于高电平的讯号；在本发明第二较佳实施方式的第一种方案中，上述De电压讯号和Do电压讯号具体可以为：当触摸屏处于显示状态的V-com讯号。
在触摸屏领域，通常将靠近IC侧的一端称为首端(也可以成为头端)，将远离IC侧的一端称为尾端。
在触摸屏领域，TP讯号未运作具体可以包括：TP讯号未处于TP sensing(触控侦测区间)内；TP讯号未运作包括但不限于：TP讯号处于LCD Display区间和触摸屏处于前段检测时(即IC尚未上线时)。当IC尚未上线时，De电压讯号、Do电压讯号和switch讯号均可以由测试平台的针头提供，当然在实际应用中，上述讯号也可以由其他的设备或装置提供，例如通过测试专用IC来提供上述讯号。
参阅图3，图3中的多个开关管中相邻的开关管的S(源)极分别通过二条金属线32输入De电压讯号和Do电压讯号，下面依据图3以及本发明第二较佳实施方式的工作原理来说明本发明第二较佳实施方式的效果，由于在尾端增加了开关管组30，当TP处于未运作时，switch讯号输出高电平，开关管组的所有开关管均导通，此时，De电压讯号和Do电压讯号均可以为V-com讯号，V-com讯号可以从com ITO的首端和尾端输入到每个ITO区间；为了方便描述，这里还是将单个ITO区间的电阻设为R，则V-com讯号到每个ITO区间的电阻为并联连接的V-com讯号从首端输入到每个ITO区间的电阻和V-com讯号从尾端输入到每个ITO区间的电阻，采用现有技术的方案中阻值的最大差值为4R，而采用本发明第二较佳实施方式的方案的V-com讯号输入到第一列中每个ITO区间的电阻值从最大的5R降低到1.5R(具体的计算方法可以参见本发明第一较佳实施方式中的计算方法)，阻值的最大差值为0.66R(具体的计算方法可以参见本发明第一较佳实施方式中的计算方法)，所以本发明 第二较佳实施方式的方案的阻值的均匀性好，所以本发明第二较佳实施方式能够有效的减少了显示面板闪烁或区域性mura。当TP处于运作时，即TP处于TP sensing内，此时Switch讯号输出低电平，开关管组20内的所有开关关闭，所有开关管不工作，V-com讯号也无法传递到ITO区间，这样就不会影响TP扫描。
在本发明第二较佳实施方式的第二种方案中，上述De电压讯号和Do电压讯号具体可以为：当触摸屏处于前段检测(即IC尚未上线时)的一对正反向电压讯号。
在本发明的一个实施例中，上述正反向电压讯号具体可以包括：高电平电压讯号和低电平电压讯号，其中De电压讯号可以为高电平讯号，Do电压讯号可以为低电平讯号，在本发明的另一个实施例中，上述正反向电压讯号具体可以包括：低电平电压讯号和高电平电压讯号，其中De电压讯号可以为低电平讯号，Do电压讯号可以为高电平讯号。
在触摸屏领域，上述高电平电压讯号通常也可以称为正检测信号，上述低电平电压讯号通常也可以称为反检测讯号。
下面通过本发明第二较佳实施方式的第二种方案的实现原理来说明本发明第二较佳实施方式的第二种方案的效果，如图3所示，多个开关管中相邻的开关管的S(源)极分别通过二条金属线32输入De电压讯号和Do电压讯号，由于在尾端增加了开关管组30，当TP处于未运作时，switch讯号输出高电平，开关管组的所有开关管均导通，此时，De电压讯号和Do电压讯号可以分别为高电平电压讯号和低电平电压讯号，这样多个相邻的开关管分别输入De电压讯号和Do电压讯号，开关管导通后，De电压讯号和Do电压讯号分别通过相邻的金属线输入到相邻的ITO区间中，此时，相邻的ITO区间将显示亮暗交错的状态，如果com ITO中有ITO区间损坏，该损坏的ITO区间与其相邻的ITO区间将不会显示成亮暗交错的状态，这样检测人员就可以非常容易的区分出com ITO中损坏的ITO区间。所以本发明第二较佳实施方式的第二种方案具有易于检测损坏ITO区间的优点。当TP处于运作时，即TP处于TP sensing内，此时Switch讯号输出低电平，开关管组30内的所有开关关闭，所有开关管不工作，V-com讯号也无法传递到ITO区间，这样就不会影响TP扫 描。
参阅图4，图4为本发明提供的第三较佳实施方式的触摸屏拉线配置电路示意图，如图4所示，该触摸屏拉线配置电路可以包括：com ITO内的ITO区间41、金属线42、触控孔43和集成电路IC；其中，在现有的触摸屏拉线配置电路增加了首端开关管组40和尾端开关管组401，该首端开关管组40和尾端开关管组401均可以包括：多个开关管，多个开关管中每个开关管的G(栅)极均与开关(switch)讯号连接，多个开关管的D(漏)极依次与com ITO内金属线连接，多个开关管中相邻的开关管的S(源)极分别通过二条金属线42输入De电压讯号和Do电压讯号；上述switch讯号具体可以为：TP讯号未运作时处于高电平的讯号；在本发明第三较佳实施方式中，上述De电压讯号和Do电压讯号具体可以为：当触摸屏处于前段检测(即IC尚未上线时)的一对正反向电压讯号；com ITO内每条金属线输入的电讯号为同一电讯号，此设置是为了避免金属线的首端输入高电平电压讯号，金属线的尾端输入低电平电压讯号，这样会使得同一个ITO区间输入的电压讯号不同而无法显示。
在本发明的一个实施例中，上述正反向电压讯号具体可以包括：高电平电压讯号和低电平电压讯号，其中De电压讯号可以为高电平讯号，Do电压讯号可以为低电平讯号，在本发明的另一个实施例中，上述正反向电压讯号具体可以包括：低电平电压讯号和高电平电压讯号，其中De电压讯号可以为低电平讯号，Do电压讯号可以为高电平讯号。
在触摸屏领域，上述高电平电压讯号通常也可以称为正检测信号，上述低电平电压讯号通常也可以称为反检测讯号。
本发明第三较佳实施方式中的方案提供了首端开关管组和尾端开关管组，此种方案降低前段检测时De电压讯号和Do电压讯号输入到ITO区间的电阻，因为De电压讯号和Do电压讯号可以通过首端开关管组和尾端开关管组同时输入De电压讯号和Do电压讯号，此时De电压讯号和Do电压讯号输入到ITO区间的电阻与本发明第一较佳实施方式和本发明第二较佳实施方式中的V-com讯号到每个ITO区间的电阻类似，均为并联电阻，所以本发明第三较佳实施方式可以有效的降低前段检测时De电压讯号和Do电压讯号输入到ITO区间的电阻。
优选的，上述开关管均可以为TFT(英文全称：Thin Film Transistor，中文：薄膜晶体管)。当然在实际应用中，也可以选择其他类型的开关管，例如场效应管。
参阅图5、图6，图5为本发明提供的第四较佳实施方式的触摸屏拉线配置电路示意图，图6为首端开关管组的放大示意图，其中60表示首端开关管子组；如图5所示，该触摸屏拉线配置电路可以包括：com ITO内的ITO区间51、金属线52、触控孔53和集成电路IC；其中，在现有的触摸屏拉线配置电路增加了首端开关管组50和尾端开关管组501，该首端开关管组50和尾端开关管组501均可以包括：多个开关管，多个开关管中每个开关管的G(栅)极均输入开关(switch)讯号，多个开关管的D(漏)极依次与com ITO内金属线连接，多个开关管按顺序分成多个开关管子组，每个开关管子组中包括n(这里以n＝3个为例)个开关管，每个开关管子组中的三个开关管的S(源)极分别通过三条金属线52输入De电压讯号、Dm电压讯号和Do电压讯号；上述switch讯号具体可以为：TP讯号未运作时处于高电平的讯号；在本发明第四较佳实施方式中，上述De电压讯号、Dm电压讯号和Do电压讯号具体可以为：当触摸屏处于前段检测(即IC尚未上线时)的三种不同电压值的电压讯号；com ITO内每条金属线输入的电压讯号为同一电压讯号，此设置是为了避免金属线的首端输入一种电压讯号，而尾端输入另一种电压讯号，这样会使得同一个ITO区间输入的电压讯号不同导致ITO区间无法显示。
在本发明的一个实施例中，上述三种不同电压值的电压讯号具体可以包括：高电平电压讯号、中电平电压讯号和低电平电压讯号，其中De电压讯号可以为高电平讯号，Dm电压讯号可以为中电平电压讯号，Do电压讯号可以为低电平讯号，在本发明的另一个实施例中，上述三种不同电压值的电压讯号也可以进行更换，例如Do电压讯号可以为高电平讯号，Dm电压讯号可以为中电平电压讯号，De电压讯号可以为低电平讯号；当然也可以为Dm电压讯号可以为高电平讯号，De电压讯号可以为中电平电压讯号，Do电压讯号可以为低电平讯号；当然在实际应用中，还可以有其他的组合方式，本发明第四较佳实施方式中并不限制上述De、Dm、Do的具体属于何种电压讯号，只要上述De、Dm、Do电压讯号不同即可；这里不在赘述。
本发明第四较佳实施方式中的方案提供了首端开关管组和尾端开关管组，此种方案降低前段检测时三种电压讯号输入到ITO区间的电阻，因为三种电压讯号可以通过首端开关管组和尾端开关管组同时输入到ITO区间，此时三种电压讯号输入到ITO区间的电阻与本发明第一较佳实施方式和本发明第二较佳实施方式中的V-com讯号到每个ITO区间的电阻类似，均为并联电阻，所以本发明第四较佳实施方式可以有效的降低前段检测时三种电压讯号输入到ITO区间的电阻。但是其相比本发明第三较佳实施方式，由于其增加了一条金属线，所以其线路复杂，导致集成度增加，增加了成本。另外，如果取n大于3，则相应的多个开关管的连接方式与n等于3类似，其技术效果以及技术缺点也与n等于3类似，这里不再赘述。
此外，本发明还提供一种显示面板，该显示面板包括：触摸屏拉线配置电路。

参阅图2，图2中的多个开关的S(源)极输入一个电压讯号，下面依据图2以及本发明第一较佳实施方式的工作原理来说明本发明第一较佳实施方 式的效果，由于在尾端增加了开关管组20，当TP处于未运作时，switch讯号输出高电平，开关管组的所有开关管均导通，此时，电压讯号可以为V-com讯号，V-com讯号可以从com ITO的首端和尾端输入到每个ITO区间；为了方便描述，这里还是将单个ITO区间的电阻设为R，则V-com讯号到每个ITO区间的电阻(为了描述的方便将V-com讯号到每个ITO区间的电阻称为R并)为并联连接的V-com讯号从首端输入到每个ITO区间的电阻和V-com讯号从尾端输入到每个ITO区间的电阻，R首表示V-com讯号从首端输入到每个ITO区间的电阻，R尾表示V-com讯号从尾端输入到每个ITO区间的电阻；以第一个ITO区间210为例，R首210＝R；R尾210＝5R，则R并210＝0.84R；以第三个ITO区间213为例，R首213＝3R；R尾213＝3R，则R并213＝1.5R；以第五个ITO区间215为例，R首215＝R；R尾215＝5R，则R并215＝0.84R；从上述计算可以看出，当采用本发明第一较佳实施方式的技术方案以后，以第一列为例，V-com讯号输入到第一列中每个ITO区间的电阻值从最大的5R降低到1.5R，最小的阻值从R降低到0.84R，所以本发明第一较佳实施方式降低了V-com讯号传递至ITO区间的阻值；另外，采用现有技术的方案中阻值的最大差值为4R，而采用本发明第一较佳实施方式的方案的阻值的最大差值为0.66R，所以本发明第一较佳实施方式的方案的阻值的均匀性好，所以本发明第一较佳实施方式能够有效的减少了显示面板闪烁或区域性mura。当TP处于运作时，即TP处于TP sensing内，此时Switch讯号输出低电平，开关管组20内的所有开关关闭，所有开关管不工作，V-com讯号也无法传递到ITO区间，这样就不会影响TP扫描。
参阅图2，由于本发明第一较佳实施方式中的switch信号在TP讯号未运行时为高电平，其不会影响触摸屏扫描，并且有效的减少了触摸屏的短路现象，因为如果在TP讯号处于TP sensing内switch信号也处于高电平时，由于switch信号处于高电平，则开关管组内所有的开关管均会开通，从而使得V-com讯号也能传递到每个ITO区间，由于TP讯号处于TP sensing内，所以当检测到触控讯号时，触控讯号也能够传递到ITO区间，此时ITO区间内有两个不同的讯号，这样很容易使得ITO区间短路(short)，所以switch信号在TP讯号未运行时为高电平能够有效的减少触摸屏的短路，降低故障率，提高安全性。
