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作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。
参照图1，根据本发明的触控面板包括阵列结构1、液晶层2、彩膜结构3、间隔层4和盖板结构5，其中，液晶层2则位于阵列结构1和彩膜结构3之间，间隔层4形成在彩膜结构3和盖板结构5之间。具体地，阵列结构1包括阵列基板101、以及依次形成在阵列基板101上的数据线层102、栅线层103和触控传输层104，而彩膜结构3包括彩膜基板301和RGB滤光层302，其中，彩膜基板301通过口字胶粘结至触控接收层502的下表面上，以使得间隔层4形成在口字胶围成的区域内，而RGB滤光层302形成在彩膜基板301的面向液晶层2的一侧，盖板结构5包括盖板501和触控接收层502，触控接收层502形成在盖板501的面向液晶层2的一侧，具体地，触控接收层502通过粘胶粘接在盖板501的下表面上，触控传输层104和触控接收层502能够作为电容的两个电极，当手指按压盖板5时，按压力致使盖板结构5和彩膜结构3之间的间隔层4发生形变，影响了触摸点附近两个电极之间的耦合，从而改变了这两个电极之间的电容量。检测互电容大小时，触控传输层104依次发出激励信号，触控接收层502同时接收信号，这样可以得到触控传输层104和触控接收层502之间的电容值大小，即整个触摸屏的二维平面的电容大小。根据触摸屏二维电容变化量数据，可以计算出每一个触摸点的坐标，从而能够为触控面板提 供3D触控信号，因而根据本发明的触控面板能够利用自身结构实现3D触控传感器功能，即能够实现内嵌3D触控传感器功能，而无需增加外部的压力触控传感器，并且对系统端无特殊要求，能够降低系统端的复杂度。
进一步地，根据本发明的触控面板还设有触控信号走线(未示出)，该触控信号走线将触控接收层502与控制芯片6相连，控制芯片6设置在阵列基板101上，控制芯片6能够接收触控接收层502的信号，通过分析触控接收层502的电量变化，从而可以分析触控传输层104和触控接收层502的电容变化，控制芯片6能够将该电容信号作为操作信号传输至主板，从而实现系统端的相应操作。
优选地，触控接收层502由ITO(Indium Tin Oxides，氧化铟锡)制成。
请参阅图2，示出本发明的触控面板中的驱动模块7的电路图，该驱动模块7将每一帧分成显示模式和触控模式，以控制所述触控传输层104的信号，在显示模式时，驱动模块7向触控传输层104提供显示信号，此时，触控传输层104用作显示时的公共电压层，在触控模式时，驱动模块7向触控传输层104提供触控信号。具体地，驱动模块7包括显示信号产生单元701、触控信号产生单元702和开关切换单元703，开关切换单元703用于在显示模式时将触控传输层104与显示信号产生单元701相连，在触控模式时将触控传输层104与触控信号产生单元702相连，此时，触控传输层104和触控接收层502之间会形成自电容，当手指按压盖板5时，按压力致使盖板结构5和彩膜结构3之间的间隔层4发生形变，致使触控传输层104和触控接收层502的电容发生变化，通过对前述电容变化量的检测，能够产生3D触控信号，因而能够实现内嵌3D触控传感器功能。因此，根据本发明的触控面板通过驱动模块7的开关切换单元703的分时控制，能够实现显示与触控一体化的效果。
可选地，间隔层4中可以填充有光学透明胶(Optical Clear Adhesive，OCA)或者光学透明树脂(Optical Clear Resin，OCR)，光学透明胶或者光学透明树脂具有粘合的作用，使得触控接收层502能够与盖板4结合得更紧密，并且光学透明胶或者光学透明树脂具有弹性，因此当手指按压盖板时，盖板501仍然能够发生形变，仍然能够使得触控传输层104和触控接收层502之间的电容发生变化，从而能够实现3D触控功能。
需要说明，数据线层102和栅线层103的位置可以互换，而不会影响触控面板的功能。
请参阅图3，示出触控传输层104和触控接收层502之间的位置关系，其中触控传输层104包括平行设置的多个触控传输部14，而触控接收层502包括平行设置的多个触控接收部52，例如触控传输部14的数量为30个，而触控接收部52的数量为18个，触控传输部44和触控接收部52之间呈垂直分布，因而能够确保触控电场覆盖触控面板的每一位置点，触控传输部44和触控接收部52交叉的部分能够形成互电容的两个电极，当手指按压盖板5时，按压力致使盖板结构5和彩膜结构3之间的间隔层4发生形变，影响了触摸点附近两个电极之间的耦合，从而改变了这两个电极之间的电容量。检测互电容大小时，触控传输层104依次发出激励信号，触控接收层502同时接收信号，这样可以得到触控传输层104和触控接收层502之间的电容值大小，即整个触摸屏的二维平面的电容大小。根据触摸屏二维电容变化量数据，可以计算出每一个触摸点的坐标，从而能够实现内嵌3D触控传感器功能。
需要说明，触控传输层104的触控传输部14和触控接收层502触控的接收部52之间能够有其他分布方式，例如呈45度角分布。
请参阅图4，示出触控传输层104和触控接收层502之间的电场分布，其中实线表示的电场线有一部分在盖板的远离阵列基板101的一侧分布，该部分电场线可以用于2D触控，而虚线表示的电场线则分布在触控传输层104和触控接收层502之间，因此当手指按压盖板时，盖板501仍然能够发生形变，仍然能够使得触控传输层104和触控接收层502之间的电容发生变化，从而能够实现3D触控功能。2D触控和3D触控可以通过分时控制实现，或者2D触控和3D触控信号可以同时收集，并同时传输至控制芯片6中进行分离处理。因此，根据本发明的触控面板能够同时实现2D触控和3D触控功能。
本发明提供的触控面板，其可以运用在各种移动终端中，例如，移动终端可以包括经无线接入网RAN与一个或多个核心网进行通信的用户设备，该用户设备可以是移动电话(“蜂窝”电话)、具有移动终端的计算机等，例如，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。又例如，该移动终端可以包括手 机、平板电脑、个人数字助理PDA、销售终端POS或车载电脑等。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
