一、觸摸屏簡介(Materials and Systematic Solution)
觸摸屏是英文叫Touch Panel,其本質(zhì)是傳感器,它由觸摸檢測部件和觸摸屏控制器組成。觸摸檢測部件安裝在顯示器屏幕前面,用于檢測用戶觸摸位置,接受后送觸摸屏控制器;觸摸屏控制器的主要作用是從觸摸點(diǎn)檢測裝置接收觸摸信息,并將它轉(zhuǎn)換成觸點(diǎn)坐標(biāo)送給CPU,同時能接收CPU發(fā)來的命令并加以執(zhí)行。觸摸屏具有堅(jiān)固耐用、反應(yīng)速度快、節(jié)省空間、易于交流等許多優(yōu)點(diǎn)。利用這種技術(shù),只要用手指輕輕地指碰計(jì)算機(jī)顯示屏上的圖符或文字就能實(shí)現(xiàn)對主機(jī)操作,從而使人機(jī)交互更為直接了當(dāng),這種技術(shù)極大方便了那些不懂電腦操作的用戶。觸摸屏的應(yīng)用范圍非常廣闊,主要有公共信息的查詢,如電信局、稅務(wù)局、銀行、電力等部門的業(yè)務(wù)查詢;城市街頭的信息查詢;此外還可廣泛應(yīng)用于企業(yè)辦公、工業(yè)控制、軍事指揮、電子游戲、點(diǎn)歌點(diǎn)菜、多媒體教學(xué)、房地產(chǎn)預(yù)售等,觸摸屏也開始走入家庭。
Touch panel is a sensor, which consists of touch detection parts, and touch panel controller. Touch detection components are installed in front of the monitor screen to detect the touch location, and send the evacuation to the touch panel controller; Touch Screen Controller's primary role is to receive detection device information from the touch-point touch, and will convert them into a contact coordinates given to CPU which at the same time can receive commands and implement. Touch plane has a lot of performances: sturdy and durable, high reaction speed, space-saving, easy to exchange and so on. With this technology, as long as the fingers gently touch the computer screen or text on the icons, it will be able to achieve the master operation, thus make the machine interaction much more straightforward. This technique provides great convenience to those who do not know computer operation. Touch panel has very broad range of applications, mainly in public information inquiries, such as the bureau, tax, banking, electricity and other sectors of business inquiries; city streets information inquiries; also can be widely used in corporate offices, industrial control, military command, electronic games, multi-media teaching, real estate pre-sales and so on. Touch screen will also come into family in the future.
二、觸摸屏分類及特點(diǎn):
(Types of Touch Panel and Characters)
觸摸屏可分為紅外線式、電阻式、表面聲波式和電容式觸摸屏四種,它們之間性能比較如下:

三、材料配套解決方案(Materials and Systematic Solution)
目前市場上的觸摸屏與電阻式觸摸屏與電容式觸摸屏為主,我司針對該兩種類型的觸摸屏根據(jù)工藝制程形成配套的材料解決方案。
Currently the resistive touch panel and capacitive touch panel are very popular. Our company develops the materials according to the manufacturing process.

藍(lán)色框( )內(nèi)物料為我司配套產(chǎn)品。
②、電容式觸摸屏配套物料(Capacitive Touch Panel and Material)
電容屏的工藝流程因結(jié)構(gòu)不同而異,目前大部分廠家做的都是層與層之間的貼合工作,對此目前我們主要引進(jìn)了用于貼合的OCA與UV膠。
The process of capacitance touch panel varies due to the structure. Most manufacturers are doing between layers of fitting work, which at present we mainly introduce the OCA and UV glue for fitting.
