0005-4050-450 触摸屏 感应式液晶显示装置

【产品详情】

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。

【英文介绍】

0005-4050-450 Touch Panel (Touch Panel), also known as "touch screen", "touch panel", is an inductive liquid crystal display device that can receive touch input signals, when touching the graphic button on the screen, the haptic feedback system on the screen can drive various connecting devices according to pre-programmed programs. It can be used to replace the mechanical button panel and create a vivid audio and video effect through the LCD display screen.

Since 1974, when the world's earliest resistive touch screen appeared, with the development of science and technology and the growth of application needs, various touch technologies have been born to adapt to various industries and levels of application. Today, commercialized touch screen technologies that have been formed include: Resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, surface acoustic wave (SAW) technology touch screen, etc., and has been widely used in mobile phones, tablet computers, retail, public information inquiry, multimedia information system, medical instruments, industrial automatic control, entertainment and catering industry, automatic ticketing system, education system and many other fields.

0005-4050-450 touch screen technology is the most acceptable computer input method for ordinary people after keyboard, mouse, handwriting pad and voice input. Using this technology, the user can operate the host computer as long as the finger gently touches the graph or text on the computer display screen, so that the human-computer interaction is more straightforward. This technology is extremely convenient for users and is a very attractive new multimedia interactive device.

0005-4050-450 The essence of the touch screen is a sensor, which is composed of touch detection components and touch screen controllers. The touch detection component is installed in front of the display screen to detect the user's touch position and accept the rear touch screen controller; The main function of the touch screen controller is to receive touch information from the touch point detection device, and convert it into contact coordinates to the CPU, and at the same time receive the command sent by the CPU and execute it.
