0005-4050-450 GEA

0005-4050-450触摸屏（Touch Panel）又称为“触控屏”、“触控面板”，是一种可接收触头等输入讯号的感应式液晶显示装置，当接触了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式驱动各种连结装置，可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。

0005-4050-450从1974开始出现世界上最早的电阻式触摸屏以来，随着科技的发展和应用需 求的增长，各种触摸技术相继诞生以适应各种行业和层次的应用。如今，已经形成了商业化的触摸屏技术包括：电阻技术触摸屏、电容技术触摸屏、红外线技术触 摸屏、表面声波（SAW）技术触摸屏等，并已广泛应用到了手机、平板电脑、零售业、公共信息查询、多媒体信息系统、医疗仪器、工业自动控制、娱乐与餐 饮业、自动售票系统、 教育系统等许多领域。

0005-4050-450触摸屏技术是继键盘、鼠标、手写板、语音输入后最为普通百姓所易接受的计算机输入方式。利用这种技术，用户只要用手指轻轻地触碰计算机显示屏上的图符或文字就能实现对主机操作，从而使人机交互更为直截了当。这种技术极大方便了用户，是极富吸引力的全新多媒体交互设备。

0005-4050-450触摸屏的本质是传感器，它由触摸检测部件和触摸屏控制器组成。触摸检测部件安装在显示器屏幕前面，用于检测用户触摸位置，接受后送触摸屏控制器；触摸屏控制器的主要作用是从触摸点检测装置接收触摸信息，并将它转换成触点坐标送给CPU，同时能接收CPU发来的命令并加以执行。

005-4050-450 Touch Panel, also known as “touch screen” and “touch panel”, is an inductive liquid crystal 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 connection devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio-visual effects through the LCD screen.

005-4050-450 Since the earliest resistive touch screen appeared in the world in 1974, with the development of science and technology and the growth of application demand, various touch technologies have been born one after another to adapt to various industries and levels of applications. Nowadays, commercial touch screen technologies have been formed, including resistance technology touch screen, capacitance technology touch screen, infrared technology touch screen, surface acoustic wave (SAW) technology touch screen, etc., and have been widely used in many fields, such as mobile phones, tablet computers, retail, public information inquiry, multimedia information systems, medical instruments, industrial automatic control, entertainment and catering industry, automatic ticketing system, education system, etc.

005-4050-450 touch screen technology is the most acceptable computer input method for ordinary people after keyboard, mouse, tablet and voice input. With this technology, users can operate the host computer by lightly touching the icons or characters on the computer display screen with their fingers, thus making human-computer interaction more straightforward. This technology is very convenient for users, and it is an attractive new multimedia interactive device.

005-4050-450 The essence of a touch screen is a sensor, which consists of a touch detection component and a touch screen controller. The touch detection part is instal in front of that display screen, is used for detect the touch position of the user, and is sent back to the touch screen controller; The main function of the touch screen controller is to receive touch information from the touch point detection device, convert it into contact coordinates and send it to the CPU, and at the same time, it can receive the commands sent by the CPU and execute them.
