Description

触控显示面板、触控方法及触控显示装置 【技术领域】
本申请涉及显示技术领域，特别是涉及一种触控显示面板、触控方法及触控显示装置。
【背景技术】
触摸显示屏作为一种输入媒介，是目前最简单、方便的一种人机交互方式。触控显示面板依照其感测方式的不同而大致分为电阻式触控显示面板、电容式触控显示面板、光学式触控显示面板、声波式触控显示面板以及电磁式触控显示面板。由于电容式触控显示面板具有反应时间快、可靠度桂以及耐用度高等优点，因此，电容式触控显示面板己被广泛地使用于电子产品中。
如图1所示，现有电容式触控显示面板在显示区域A内，驱动导线Tx与接收导线Rx分别用两层ITO(Indium Tin Oxide，氧化铟锡)导电材料层制作，设置在不共面的两平行面上且相互电性绝缘，多个长条状的驱动导线Tx沿X方向排列，多个长条状的接收导线Rx沿Y方向(与X方向垂直)排列。接收导线Rx的触控信号传输线3可以从显示区域的下侧连接到处理芯片1；而驱动导线Tx的触控信号传输线4则需要从显示区域的左右两侧引出，沿Y方向延伸后连接到处理芯片1，因此，显示区域的左右两侧存在着触控信号传输线区域2。另一方面，为了规避显示屏上摄像头和听筒的设置区域，将触摸显示屏设置有一缺口，缺口的设置切断了阵列分布的驱动导线Tx和接收导线Rx，为了避免出现线路中断，利用触控信号传输线将缺口侧边的驱动导线Tx和接收导线Rx连接起来，触控信号传输线设置在缺口下方。本申请的发明人发现，现有的触控信号传输线布置方法不仅占据了显示区域的面积，降低了显示 屏的屏占比，不利于实现全屏化，而且也会导致缺口边缘的像素缺失，影响计算精度，进而影响识别效果。
【发明内容】
本申请提供一种触控显示面板及其触控设计方法和触控显示装置，用于解决现有技术中，为了规避显示屏上摄像头和听筒的设置区域而导致的屏占比降低以及像素缺失，影响触控识别效果的问题。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种触控显示面板，所述触控显示面板包括：多条沿第一方向设置的驱动导线、多条沿第二方向设置的接收导线，其中，所述第一方向和所述第二方向相互垂直，所述驱动导线和所述接收导线构成耦合电容，所述耦合电容用于将触控动作转化为触控信号；所述触控显示面板的其中一侧设置有U形缺口，所述U形缺口将所述触控显示面板划分为三个独立的线路体系，其中，所述线路体系中的所述驱动导线和所述接收导线在所述U形缺口处均可形成独立的回路，使得所述触控信号可通过所述回路传输；所述触控显示面板还包括多个连接块，所述连接块包括驱动连接块以及接收连接块，其中：所述驱动连接块设置在所述驱动导线的两端，并将相邻的两根驱动导线电连接，使得所述驱动导线形成回路；所述接收连接块设置在所述接收导线的两端，并将相邻的两根接收导线电连接，使得所述接收导线形成回路。
为解决上述技术问题，本申请采用的另一个技术方案是：提供一种触控方法，所述触控方法包括：提供一触控显示面板，所述触控显示面板包括：多条沿第一方向设置的驱动导线、多条沿第二方向设置的接收导线，其中，所述第一方向和所述第二方向相互垂直，所述驱动导线和所述接收导线构成耦合电容，所述耦合电容用于将触控动作转化为触控信号；所述触控显示面板的其中一侧设置有缺口，所述缺口将所述触控 显示面板划分为若干个独立的线路体系，其中，所述线路体系中的所述驱动导线和所述接收导线在所述缺口处均可形成独立的回路，使得所述触控信号可通过所述回路传输；判断触控动作所在的线路体系；根据所述触控动作所在的所述线路体系进行信号处理；输出与所述信号处理结果对应的显示面板触控效果。
为解决上述技术问题，本申请采用的又一个技术方案是：提供一种触控显示装置，所述触控显示装置包括触控显示面板，所述触控显示面板包括：多条沿第一方向设置的驱动导线、多条沿第二方向设置的接收导线，其中，所述第一方向和所述第二方向相互垂直，所述驱动导线和所述接收导线构成耦合电容，所述耦合电容用于将触控动作转化为触控信号；所述触控显示面板的其中一侧设置有缺口，所述缺口将所述触控显示面板划分为若干个独立的线路体系，其中，所述线路体系中的所述驱动导线和所述接收导线在所述缺口处均可形成独立的回路，使得所述触控信号可通过所述回路传输。
上述实施例的有益效果是：通过将设置缺口的触控显示面板划分为若干个独立的线路体系，每个线路体系中的驱动导线和接收导线在缺口处均可形成独立的回路，因此每个回路可仅需要一条触控信号传输线进行信号传输，从而减小了触控信号传输线占用的无效区的面积，提升了屏占比，另外一方面，由于触控显示面板每个区域的触控点坐标是由每个独立的线路体系进行计算得到的，计算精度较高，识别结果更加精确。

请参阅图2和图3，图2是本申请触控显示面板的整体结构示意图，图3是图2中圈B位置处的局部放大示意图。触控显示面板100包括：多条沿第一方向设置的驱动导线10、多条沿第二方向设置的接收导线20，第一方向和第二方向相互垂直，驱动导线10和接收导线20构成耦合电容，耦合电容用于将触控动作转化为触控信号；触控显示面板100的其中一侧设置有缺口30，缺口30将触控显示面板100划分为若干个独立的线路体系，线路体系中的驱动导线10和接收导线20在缺口30处均可形成独立的回路，使得触控信号可通过回路传输。
具体地，驱动导线10和接收导线20位于触控显示面板100的不同层上，且在两层之间设置有绝缘层使其相互绝缘，相互绝缘的驱动导线10和接收导线20相互感应，构成耦合电容，当触控显示面板100接收到触控动作时，该触控动作改变了耦合电容的相对位置，使其之间电场发生变化，从而产生触控信号，该触控信号可以通过独立的线路体系进行传输。在本实施例中，驱动导线10沿水平方向排布，接收导线20沿竖直方向排布。
显示屏幕上存在摄像头和听筒，为了不影响摄像头和听筒发挥其作用，在触控显示面板100对应摄像头和听筒所在区域设置有缺口30，由于不同型号手机，显示屏幕上摄像头和听筒的位置不固定，且摄像头和听筒也有可能是分开设置的，因而，在触控显示面板100上设置缺口30的位置以及数量也不确定。例如：缺口30的数量可以有1个，其位置可以位于触控显示面板100的上方，下方，左方或者右方，同样可以位 于左上角以及右上角等区域；缺口30的数量也可以有2个，其位置可以位于触控显示面板100的同侧，也可以位于触控显示面板100的异侧，当然也可以位于相邻两侧等位置。在本实施例中，设置有一个缺口30，该缺口30位于触控显示面板100上方中间位置，使得触控显示面板100左右两侧的像素单元数目相等。
进一步地，触控显示面板100还包括多个连接块40，连接块40包括驱动连接块42以及接收连接块44，驱动连接块42设置在驱动导线10的两端，并将相邻的两根驱动导线10电连接，使得驱动导线10形成回路；接收连接块44设置在接收导线20的两端，并将相邻的两根接收导线20电连接，使得接收导线20形成回路。
具体地，在本实施例中，由于驱动导线10是水平排布地，因而驱动连接块42沿触控显示面板100的竖直方向排布在触控显示面板100的竖直两侧边缘上以及缺口30的竖直两侧边缘上，且竖直排布的每个驱动连接块42的相异两端分别连接两根相邻的驱动导线10，从而可以形成驱动导线10传输回路。由于接收导线20是竖直排布地，因而接收连接块44沿触控显示面板100的水平方向排布在触控显示面板100的水平两侧边缘上及缺口30的水平底部边缘上，且水平排布的每个接收连接块44的相异两端分别连接两根相邻的接收导线20，从而可以形成接收导线20传输回路。
进一步地，触控显示面板100还包括多个触控信号传输线50以及处理芯片60，触控信号传输线50将每个独立的线路***的触控信号传输到处理芯片60中。具体地，触控信号传输线50一端与连接块40连接，另一端与绑定垫62电连接，绑定垫62进一步与处理芯片60电连接，从而将每个回路中的触控信号传输给处理芯片60，处理芯片60用于根据触控信号传输线50传输的触控信号计算该触控信号所在的触控 点位置，进而根据该触控点位置形成相应的触控效果。
进一步地，触控信号传输线50与同一个回路中的其中一个连接块40电连接。具体地，同一个回路可以是驱动导线10与两个驱动连接块42构成的驱动回路，触控信号传输线50与其中一个驱动连接块42电连接，从而将驱动回路中的触控信号传输给处理芯片60，也可以是接收导线20与两个接收连接块44构成的接收回路，触控信号传输线50与其中一个接收连接块44电连接，从而将接收回路中的触控信号传输给处理芯片60。
进一步地，缺口30为U形结构，缺口30将触控显示面板100划分为三个独立的线路体系。当然，在其他实施例中，缺口30的形状也可以是其他规则或不规则形状，例如梯形以及正六边形等形状，独立的线路体系是根据缺口30的形状进行具体的划分的，例如正六边形的缺口可以将触控显示面板100划分为5个独立的线路体系。
进一步地，在本实施例中，线路体系包括第一线路体系C1、第二线路体系C2以及第三线路体系C3，第一线路体系C1自缺口30的U形底边所在的行向远离缺口30方向延伸至触控显示面板100的边缘；第二线路体系C2从缺口30的其中一条侧边所在的列向背离缺口30方向延伸至触控显示面板100的边缘；第三线路体系C3从缺口30的另外一条侧边所在的列向背离缺口30方向延伸至触控显示面板100的边缘。
在本实施例中，对于触控信号传输线50与驱动连接块42的电连接关系可以如下设置：在第一线路体系C1中，触控信号传输线50与触控显示面板100两侧中的任一侧的驱动连接块42连续相连，或者与两侧的驱动连接块42交叉相连。在第二线路体系C2中，触控信号传输线50与远离缺口30一侧的驱动连接块42连续相连。在第三线路体系C3中，触控信号传输线50与远离缺口30一侧的驱动连接块42连续相连。
对于触控信号传输线50与接收连接块44的电连接关系可以如下设置：触控信号传输线50仅与触控显示面板100的第一线路体系C1远离缺口30一侧的接收连接块44连续相连。
进一步地，线路体系中的触控点与触控显示面板100中的像素单元一一对应；第一线路体系C1包括(m-w)行和n列像素单元，第二线路体系C2包括w行像素单元和x 1列像素单元，第三线路体系C3包括w行像素单元和x 2列像素单元，其中，m表示所述触控显示面板100包含的所述像素单元总行数，n表示所述触控显示面板100包含的所述像素单元总列数，w表示所述缺口30占据的所述像素单元行数，x 1、x 2表示所述缺口30两侧的所述触控显示面板100包含的所述像素单元列数，m、n、w、x 1、x 2为自然数，且w＜m，x 1+x 2＜n。具体地，触控显示面板100识别触控动作的原理是对触控显示面板100中的像素单元的位置坐标进行识别，像素单元的位置坐标即构成了触控点的位置坐标，因而线路体系中的触控点与触控显示面板100中的像素单元一一对应。根据3个线路体系所包含的像素单元行数和列数，可以计算出第一线路体系C1包含的像素单元数为：
P1＝(m-w)×n；
第二线路体系C2包含的像素单元数为：
P2＝x 1×w；
第三线路体系C3包含的像素单元数为：
P3＝x 2×w。
为了方便计算，本实施例中，将U型缺口30设置在触控显示面板100中间位置，进而该缺口30正好平分驱动导线10回路，即x 1＝x 2使得缺口30左右两侧的第二线路体系C2和第三线路体系C3的像素数相等，即P2＝P3＝x 1×w。
可选地，请参阅图4，并请继续参阅图3，图4是本申请触控显示面板另一实施例中的线路体系划分示意图。在其他实施例中，线路体系也可以划分为：第一线路体系C1a自缺口30的U形其中一条侧边所在的列向远离缺口30方向延伸至触控显示面板100的边缘；第二线路体系C2a从缺口30的底边向背离缺口30方向延伸至触控显示面板100的边缘；第三线路体系C3a从缺口30的另外一条侧边所在的列向背离缺口30方向延伸至触控显示面板100的边缘。
此时，第一线路体系C1a包括m行像素单元和x 1列像素单元，第二线路体系C2a包括(m-w)行和(n-x 1-x 2)列像素单元，第三线路体系C3a包括m行像素单元和x 2列像素单元。第一线路体系C1a包含的像素单元数为：
P1a＝m×x 1；
第二线路体系C2a包含的像素单元数为：
P2a＝(m-w)×(n-x 1-x 2)；
第三线路体系C3a包含的像素单元数为：
P3a＝m×x 2。
本申请实施例相对于其它实施例的线路体系划分方法的好处在于：本申请的实施例将不受缺口30影响的区域作为一个面积较大的线路体系，将受缺口30影响的区域作为其余面积较小的线路体系，当处理芯片60对触控点的坐标进行计算时的计算量要相对其他划分方法的要小，因而，在对触控显示面板100的线路***进行划分时，要优选将触控显示面板100划分为一个大的线路体系以及若干小的线路体系，进而减小处理芯片60的计算复杂度。
上述实施例的有益效果是：通过将设置U型缺口30的触控显示面板100划分为若干个独立的线路体系，并在每个回路中设置一对连接块 40，并将其中一个连接块40通过触控信号传输线50连接至处理芯片60，从而将触控显示面板100接收到的触控动作通过每个独立的线路体系转化成触控信号后通过连接块40和触控信号传输线50传输给处理芯片60，进而由处理芯片60计算触控点所在的像素单元，输出对应像素单元的触控显示效果。由于每个回路仅需要一条触控信号传输线50进行信号传输，在设置缺口30一侧，由于不设置触控信号传输线，而且在不含缺口30一侧，触控信号传输线的数量减半，从而减小了无效区的面积，提升了屏占比，另外一方面，由于触控显示面板100每个区域的触控点坐标是由每个独立的线路体系进行计算得到的，计算精度较高，识别结果更加精确。
请参阅图5，并请参阅图3，图5是本申请触控方法一实施例的流程示意图。所述触控方法包括：
S10：提供一触控显示面板100，该触控显示面板100为前文所述的触控显示面板100。该触控显示面板100可以有多种结构形式，请参阅图6A-6C，图6A至6C是本申请另一实施例中不同的触控显示面板的结构示意图。图6A中的触控显示面板200包括一显示面板210以及一配置于显示面板上的触控单元220，触控单元220可内建于显示面板210中。举例而言，显示面板210可为一液晶显示面板，其包括一薄膜晶体管阵列基板212、一彩色滤光片基板214以及一液晶层216，其中液晶层216位于薄膜晶体管阵列基板212与彩色滤光片基板214之间，而触控单元220则配置于彩色滤光片基板214的内表面上。换言之，触控单元220位于彩色滤光片基板214以及液晶层216之间，即所谓的内建式设计(In-cell design)。显示面板210亦可以是有机发光显示面板(Organic light emitting display panel)、电泳显示面板(Electrophoretic display panel)或是等离子体显示面板(Plasma display panel)。触控单元220除了可内建 于显示面板210中，还可以采用其他方式与显示面板210结合，如图6B与图6C所示。请先参照图6B，触控单元220可以形成于彩色滤光片基板214的外表面上，即所谓的整合式设计(On-cell design)。当然，触控单元220亦可以先制作于一基板(例如是辅助基板230)上，再将已形成有触控单元220的基板230贴附于彩色滤光片基板214的外表面上，如图6C所示，即所谓的外贴式设计(Added-on design)。值得注意是，图6C中的基板230(即辅助基板230)以及触控单元220即构成触控基板T。由上可知，本申请的触控单元220可制作于一彩色滤光基板214、一薄膜晶体管阵列基板212或一辅助基板230上，但是并不以此为限。
进一步执行步骤S20：判断触控动作所在的线路体系。
判断触控动作的线路体系进一步包括如下子步骤：
判断触控动作是否在第一线路体系C1。假设触控动作所在的触控点的坐标为(R i，T j)，i表示触控点所在的像素单元列，j表示触控点所在的像素单元行。因为第一线路体系C1包含包括(m-w)行和n列像素单元，当0≤i≤n且0≤j＜(m-w)时，则判断该触控点位于第一线路体系C1。
若判断结果为所述触控动作不在所述第一线路体系C1，则判断所述触控动作是否在所述第二线路体系C2。具体地，当触控点不符合第一线路体系C1中点的坐标范围时，进一步判断该触控点是否位于第二线路体系C2，当0≤i≤x 1且(m-w)≤j≤m时，则判断该触控点位于第二线路体系C2。
若判断结果为所述触控动作不在所述第二线路体系C2，则判断所述触控动作是否在所述第三线路体系C3。当触控点不符合第二线路体系C2中点的坐标范围时，进一步判断该触控点是否位于第三线路体系C3，具体地，当n-x 2≤i≤n且(m-w)≤j≤m时，则判断该触控点位于第三线路体系C3。
若判断结果为所述触控动作不在所述第三线路体系C3，则所述触控动作无效。具体地，若触动点的坐标既不符合第一线路体系C1，又不符合第二线路体系C2和第三线路体系C3，则判断该触控点无效即该触控动作无效。
得到触控动作的判断结果后，进一步执行如下步骤：
S30：根据触控动作所在的线路体系进行信号处理。例如，第一线路体系C1根据触控动作产生触控信号，进而通过连接第一线路体系C1的触控信号传输线50将触控信号传输给处理芯片60。
S40：输出与信号处理结果对应的显示面板触控效果。具体地，处理芯片60接收上述任一线路体系通过触控信号传输线50传输的触控信号，并进行信号处理，从而形成对应的触控效果，经由触控显示面板100进行显示。
请参阅图7，并请继续参阅图3，图7是本申请触控方法另一实施例的流程示意图。触控方法包括如下步骤：
S100：接收触控动作。由前文所述的触控显示面板100接收触控动作。
S210：判断触控动作是否在第一线路体系C1。假设触控动作所在的触控点的坐标为(R i，T j)，i表示触控点所在的像素单元列，j表示触控点所在的像素单元行。因为第一线路体系C1包含包括(m-w)行和n列像素单元，当0≤i≤n且0≤j＜(m-w)时，则判断该触控点位于第一线路体系C1。
若判断结果为该触控点位于第一线路体系C1，则进一步执行步骤S300：信号处理。具体地，由第一线路体系C1将触控动作产生的触控信号经由触控信号传输线50传输给处理芯片60，由处理芯片60根据触控信号判断触控点的坐标，进而得到触控点对应的像素单元。
若判断结果为该触控点不位于第一线路体系C1，则进一步执行步骤S220：判断触控动作是否位于第二线路体系C2。具体地，当0≤i≤x 1且(m-w)≤j≤m时，则判断该触控点位于第二线路体系C2。若判断结果为该触控点位于第二线路体系C2，则进一步执行步骤S300：信号处理。具体地，由第二线路体系C2将触控动作产生的触控信号经由触控信号传输线50传输给处理芯片60，由处理芯片60根据触控信号判断触控点的坐标，进而得到触控点对应的像素单元。
若判断结果为该触控点不位于第二线路体系C2，则进一步执行步骤S230：判断触控动作是否位于第三线路体系C3。具体地，当n-x 2≤i≤n且(m-w)≤j≤m时，则判断该触控点位于第三线路体系C3。若判断结果为该触控点位于第三线路体系C3，则进一步执行步骤S300：信号处理。具体地，由第三线路体系C3将触控动作产生的触控信号经由触控信号传输线50传输给处理芯片60，由处理芯片60根据触控信号判断触控点的坐标，进而得到触控点对应的像素单元。
若判断结果为该触控点不位于第三线路体系C3，则该触控点无效，触控显示面板100不进行相应操作。
对触控动作进行信号处理后进一步执行步骤S400：形成触控效果。具体地，由处理芯片60根据触控点对应的像素单元，形成与对应像素单元相应的触控效果，并经由触控显示面板100显示。
上述实施例的有益效果是：通过将触控显示面板的触控区域划分为多个相互独立的线路体系，每次仅发生触控动作的线路体系工作，而其余线路体系不工作，减少了处理芯片的计算复杂度。而且将缺口所在区域的坐标点从整体线路体系中去除，使得处理芯片的处理结果更加精确。
本申请还提供了一种触控显示装置300，请参阅图8，图8是本申 请一实施例触控显示装置的结构示意图。该触控显示装置300包括上述实施例中的触控显示面板100，且该触控显示装置300的触控设计方法为上述实施例中的触控设计方法，触控显示面板100的结构以及触控设计方法请参阅前文，此处不再赘述。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
