5AP920.1505-01 触摸屏面板 用以取代机械式的按钮面板

5AP920.1505-01 触摸屏面板（Touch Panel），又称为“触控屏”或“触控面板”，是一种可接收触头等输入信号的感应式液晶显示装置。当接触屏幕上的图形按钮时，屏幕上的触觉反馈系统可根据预先编程的程序驱动各种连接设备，用以取代机械式的按钮面板，并借由液晶显示画面制造出生动的影音效果。触摸屏面板作为一种新型的电脑输入设备，是简单、方便、自然的人机交互方式，给多媒体系统以全新的面貌，是极富吸引力的全新多媒体交互设备，主要应用于公共信息查询、工业控制、军事指挥、电子游戏、多媒体教学等领域。5AP920.1505-01 触摸屏面板主要分为电容式触摸屏和电阻式触摸屏两种。电容式触摸屏是直接用手指接触触摸使用，如手机；电阻式触摸屏则必须用触笔直接接触，且需要一定的压力，因为它是通过压力使上下两层ITO发生电流感应来工作的。

5AP920.1505-01 Touch Panel, also known as “touch screen” or “touch panel”, is an inductive LCD display device that can receive input signals such as contacts. When touching the graphic buttons on the screen, the tactile feedback system on the screen can drive various connecting devices based on pre programmed programs to replace mechanical button panels and create dynamic audio and video effects through the LCD display screen. As a new type of computer input device, touch screen panels are a simple, convenient, and natural way of human-computer interaction, giving multimedia systems a new look. They are highly attractive new multimedia interaction devices, mainly used in public information inquiry, industrial control, military command, electronic games, multimedia teaching and other fields. 5AP920.1505-01 Touch screen panels are mainly divided into two types: capacitive touch screens and resistive touch screens. A capacitive touch screen is used to directly touch with fingers, such as a mobile phone; A resistive touch screen must be in direct contact with a stylus and requires a certain amount of pressure, as it works by inducing current in the upper and lower layers of ITO through pressure
