本发明涉及触控显示领域，具体地，涉及压力感应触控屏。The invention relates to the field of touch display, in particular to a pressure-sensitive touch screen.
背景技术Background technique
触摸屏因具有易操作性、直观性和灵活性等优点，已成为个人移动通信设备和综合信息终端如平板电脑和智能手机、超级笔记本电脑等的主要人机交互手段。触摸屏根据不同的触控原理可分为电阻触摸屏、电容触摸屏、红外触摸屏和表面声波(SAW)触摸屏等四种主要类型。其中电容触摸屏具有多点触控的功能，反应时间快、使用寿命长和光透过率较高，用户使用体验优越，同时随着工艺的逐步成熟，良品率得到显著提高，电容屏价格日益降低，目前已成为中小尺寸信息终端触控交互采用的主要技术。Due to its advantages of ease of operation, intuition, and flexibility, the touch screen has become the main means of human-computer interaction for personal mobile communication devices and comprehensive information terminals such as tablet computers, smart phones, and supernotebook computers. Touch screens can be divided into four main types according to different touch principles: resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave (SAW) touch screens. Among them, the capacitive touch screen has the function of multi-touch, fast response time, long service life and high light transmittance, and the user experience is superior. At present, it has become the main technology used in touch interaction of small and medium-sized information terminals.
但是电容触摸屏仅感知屏体所在平面(X，Y轴二维空间)的触摸位置，难以支持垂直于屏体平面(Z轴)的触摸参数感知。However, the capacitive touch screen only senses the touch position on the plane of the screen body (X, Y axis two-dimensional space), and it is difficult to support the touch parameter perception perpendicular to the screen body plane (Z axis).
因而，目前的触摸屏相关技术仍有待改进。Therefore, the current touch screen related technology still needs to be improved.
