Description

触控显示装置及触控显示器 技术领域
本申请涉及显示技术领域，尤其涉及一种触控显示装置及触控显示器。
 背景技术
内嵌式触控显示装置（In Cell Touch Display）是将触控电极集成于显示面板中，并且通过分时驱动的方式实现显示面板的触控功能和显示功能。由于内嵌式触控技术不用在显示面板制程之后再单独制作触控功能层，从而简化了触控显示装置的制程，并且有利于实现显示装置的轻薄化设计。因此，内嵌式触控设计已经成为触控显示装置的主流设计方案。
内嵌式触控技术在液晶显示装置中的应用十分广泛，但同时也存在着诸多问题，其中一个最严重的问题就是触控电极与背光铁框之间的寄生电容问题。如图1所示，液晶显示装置10包括液晶面板LC1和背光模组BL1；其中，触控电极11集成于液晶显示面板LC1中，背光模组BL1包括背光膜材13和支撑所述背光膜材13的背光铁框12。触控电极11和背光铁框12之间会形成虚拟电容器C。由于虚拟电容器C的电容耦合效应，触控电极11上接收到的周期性的触控信号会对虚拟电容器C产生充电和放电的效果，从而影响触控信号对触控电极11的充放电时间，进而影响触控效果。另外，触控信号对虚拟电容器C周期性的充放电作用会引起位于虚拟电容器C中的背光膜层13的震动，从而产生高频噪音，影响产品的使用效果。
 技术问题
