Description

移动终端及其触摸显示单元、触控按键
【技术领域】
本发明涉及移动终端触摸显示器触控控制的技术领域，具体是涉及一种移动终端及其触摸显示单元、触控按键。
【背景技术】
随着手机行业的发展，相对于将触摸面板设置在液晶面板上使用的原有方法，将触摸面板功能与液晶面板一体化的研究日渐盛行。触摸面板和液晶面板的一体化包括“In-cell”方法和“On-cell”两种方法。In-cell 是指将触摸面板功能嵌入到液晶像素中的方法；而On-cell 是指将触摸面板功能嵌入到彩色滤光片基板和偏光板之间的方法。新一代的Oncell 和Incell 市场份额将在未来几年得到快速增长。
在制作触摸显示面板时，通常根据客户会要求在有效显示区下方设置感应图案，感应图案通过触摸该感应图案的方法来实现独立按钮的功能。对于使用Incell或者Oncell的LCD来说，比较通用的做法是先把按键图案做在FPC（Flexible Printed Circuit，柔性电路板）上，再把FPC 贴在盖板上，最后通过贴合将LCD和盖板贴合。
触摸面板的驱动控制分为2部分控制，分别独立控制有效显示区和感应图案的Touch功能。请参阅图1，图1是现有技术移动终端的触摸显示屏的结构示意图，图中的标号1为有效显示区，标号2为独立感应图案触控区。
从上述分析可知，现有技术主要存在以下缺点：1、结构复杂，需要1个单独的FPC sensor以及2个Touch 控制单元；2、制程复杂，需要一次FPC与盖板的贴合制程。
【发明内容】

根据本发明一优选实施例，所述第一、第二开关组分别包括3个开关。
根据本发明一优选实施例，所述测试引线端板的数量为两个，且每一测试引线端板均包括3个引线端，3个引线端分别与所述第一、第二开关组内的开关连接。
根据本发明一优选实施例，所述第一开关组的开关为TFT开关，所述TFT开关的源极与触摸面板，漏极与触控传感器连接，栅极连接开关控制器。
根据本发明一优选实施例，所述第二开关组的开关为TFT开关，所述TFT开关的源极连接液晶模组，漏极连接触控传感器，栅极连接开关控制器。
为解决上述技术问题，本发明另一方面提供一种触摸显示单元，所述触摸显示单元包括上述实施例中所述的触控按键。
进一步地，本发明实施例还提供一种移动终端，所述移动终端包括上述实施例中所述的触摸显示单元。
相对于现有技术，本发明提供的移动终端及其触摸显示单元、触控按键，通过增加开关和开关控制信号，对Cell test PAD（测试引线端板）进行复用，使用Cell test PAD作为延伸区的传感器，进一步将额外的Touch功能整合到Cell上。技术改进及优点：1、不需要额外的Sensor FPC，使触摸显示单元的结构更加简单；2、省掉FPC与盖板贴合的工艺，使触摸显示单元的制程简化；3、提高Touch功能的整合度；4、提高驱动的整合度；5、提高Panel的利用效率。

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的一部分实施例，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它实施例，都属于本发明保护的范围。
请一并参阅图2和图3，图2是本发明触控按键一优选实施例的电路结构示意图；图3是触摸显示单元的结构示意简图。在LCD下边沿（Border）区域为非有效显示区，通常LCD下Border左右侧分别会留有Cell test pad，完成Cell点灯测试后这些PAD都处于不必使用的状态。本发明实施例正是利用这些PAD，作为传感器使用，对cell test PAD进行复用。
该触控按键包括触控传感器100、第一开关组200以及第二开关组300；每一开关组均包括多个开关，第一开关组200内开关的一端分别与触控面板（图中未标示）连接，另一端分别与触控传感器100连接；第二开关组300内开关的一端分别连接于触控传感器100，另一端分别连接于液晶模组（图中未标示）；触控传感器100与触摸显示单元的触摸按键区500重合。需要说明的是，本发明实施例中的Cell类型可包括非内嵌TP Cell、 Incell、 Oncell等。
优选地，该触控传感器100为触摸显示单元的测试引线端板，该测试引线端板设于触摸显示单元显示区400的边沿。第一开关组200断开，第二开关组300闭合时，测试引线端板用于液晶模组的点灯测试；第一开关组200闭合，第二开关组300断开时，测试引线端板作为触控传感器，用于侦测触摸按键区的触摸信号。
具体而言本发明是对Cell进行复用设计，左右两侧的cell test PAD分别增加第一开关组200（图中Q1、Q2、Q3…）和增加第二开关组300（P1、P2、P3…）；在本实施例中该第一、第二开关组分别包括3个开关，当然，在其他实施例中可以包括多个开关，此处对开关的数量不做具体限定。该第一开关组200和第二开关组300的开关均可以为TFT开关，例如P型、N型、C型等。而Cell test PAD形状并不限于图中所示的方形，还可以为圆形等，在本领域技术人员的理解范围内，此处不再一一列举。
当第一开关组的开关为TFT开关时，该TFT开关的源极与触摸面板，漏极与触控传感器100连接，栅极连接开关控制器或者开关信号输入源（图中未示），开关控制器或者开关信号输入源用于给该TFT开关提供开关信号。
当第二开关组的开关为TFT开关时，该TFT开关的源极连接液晶模组，漏极连接触控传感器100，栅极连接开关控制器或者开关信号输入源（图中未示），同样的，开关控制器或者开关信号输入源用于给该TFT开关提供开关信号。
测试引线端板的数量可以为两个，且每一测试引线端板均包括3个引线端，3个引线端分别与第一、第二开关组内的开关连接。当然，测试引线端板的数量也可以为多个。左右两侧分别在第一开关组200的输入侧增加一个触摸面板控制（TP control）信号。
在Cell 测试的时候，对第一开关组200提供关闭信号，对第二开关组300提供开启信号，使用cell test pad作为测试信号的输入端，以完成cell 测试；如图4所示，图4为使用cell test pad进行cell 测试的电路结构示意简图。
本实施例中，盖板上不用使用额外的FPC制作Sensor，直接贴合盖板和LCD，左右两侧的Cell test PAD与延伸需要的触摸按键区重叠，使用cell test PAD作为延伸按键的Sensor PAD。请参阅图5，图5是cell test PAD作为延伸按键的Sensor PAD的结构示意图。其中，本实施例中延伸区的Touch Sensor不限于自容型和互容型。
在利用Cell Test pad充当 Touch sensor的作用进行Cell 测试的时候，对第一开关组200提供开启信号，对第二开关组300提供关闭信号，Cell Test pad充当 Touch sensor的作用，侦查Touch信号，来实现触摸按键功能。如图6所示，图6为Cell Test pad作为 Touch sensor使用的电路结构示意简图。
相对于现有技术，本发明提供的用于触摸显示单元的触控按键，通过增加开关和开关控制信号，对Cell test PAD（测试引线端板）进行复用，使用Cell test PAD作为延伸区的传感器，进一步将额外的Touch功能整合到Cell上。技术改进及优点：1、不需要额外的Sensor FPC，使触摸显示单元的结构更加简单；2、省掉FPC与盖板贴合的工艺，使触摸显示单元的制程简化；3、提高Touch功能的整合度；4、提高驱动的整合度；5、提高Panel的利用效率。
进一步地，本发明实施例还提供一种触摸显示单元，该触摸显示单元包括一种触控按键。
该触控按键包括触控传感器100、第一开关组200以及第二开关组300；每一开关组均包括多个开关，第一开关组200内开关的一端分别与触控面板（图中未标示）连接，另一端分别与触控传感器100连接；第二开关组300内开关的一端分别连接于触控传感器100，另一端分别连接于液晶模组（图中未标示）；触控传感器100与触摸显示单元的触摸按键区500重合。需要说明的是，本发明实施例中的Cell类型可包括非内嵌TP Cell、 Incell、 Oncell等。
优选地，该触控传感器100为触摸显示单元的测试引线端板，该测试引线端板设于触摸显示单元显示区400的边沿。第一开关组200断开，第二开关组300闭合时，测试引线端板用于液晶模组的点灯测试；第一开关组200闭合，第二开关组300断开时，测试引线端板作为触控传感器，用于侦测触摸按键区的触摸信号。
具体而言本发明是对Cell进行复用设计，左右两侧的cell test PAD分别增加第一开关组200（图中Q1、Q2、Q3…）和增加第二开关组300（P1、P2、P3…）；在本实施例中该第一、第二开关组分别包括3个开关，当然，在其他实施例中可以包括多个开关，此处对开关的数量不做具体限定。该第一开关组200和第二开关组300的开关均可以为TFT开关，例如P型、N型、C型等。而Cell test PAD形状并不限于图中所示的方形，还可以为圆形等，在本领域技术人员的理解范围内，此处不再一一列举。
