Projected Capacitive Touch Screen

Specification

How it works
Once the panel is touched, there is capacitance generated between finger, touch panel surface & ITO coating. When the diamond pattern is scanned sequently, the capacitance of the diamond pattern underneath the finger is the highest, other capacitance is proportional to the distance between finger and touched area; the scanned diamond in X- coordinate will tell us which diamond pattern the finger locates in, likewise in Y-coordinate the same operation will detect the finger location, through the data obtained by scanning and weighted calculation on X,Y coordinates we can figure out the accurate area touched on panel ;

Benifit


Zoom in?zoom out?rotation: Applicable in controlling the image zoom out or zoom or rotation by two fingers touch
Sliding function: Slide text and images
Drag out: Drag out a subject to different location or into another subject
Multi-touch: it allows two fingers to control the panel simultaneously; multi-touch is fulfilled by touch panel and its software kits, able to identify multi points. Such function is completed by different action
Long life expectancy: Scoring life for resistive touch panel is 100 –thousand times (press sensing), and 225 million times for projected capacitive touch panel (capacitance induction)
Capacitive touch panel has better optical performance than resistive touch panel. Multi-layer projected capacitive transmission can reach 88%, while resistive touch panel is 83%. When used under strong light, it can show clear contents. Also it has high sensitivity , diverse operation, water-proof, anti - electromagnetic radiation advantages
High resolution to achieve good writing effect

Application


PC?Mobile phone?hand-held instrument ?E-book?GPS?information terminal?writing pad?game machine etc.
