Summary
Pricing
Touch screen revenues will increase from $4.3 B in 2009 to $13 B by 2016; touch industry is
growing 10 times faster than display industry.
 The overall average selling price of touch panels will increase nearly 8% between 2007 and
2015. In many applications, increases in panel sizes and functionality mix will offset price
declines for older panels.
 For projected capacitive pricing to become more competitive, lower-cost technologies (such as
single substrate, transparent conductor patterning, on-cell) are needed.

Projected Capacitive Construction
All projected capacitive designs have two key features in common:
The ITO layer lies behind the touch surface and is fully protected
 No Moving Parts

The most common design incorporates the concept shown below:
Projected Capacitive Technology
The most recent addition to projected capacitive technology is Multi-Touch
Multi-Touch Projected Capacitive Sensor
Projected Capacitive Technology
There are Two Projected Capacitive Sensing Methods:
Self-Capacitance (Rarely Used Now)
 Mutual Capacitance (Most Common)

Mutual – How it Works
Contains grid of sensing and driving lines to determine touch location.
 Makes use of the fact that most conductive objects are able to hold a charge if they are very close
together. If another conductive object, like a finger, bridges the gap, the charge field is interrupted
and detected by the microcontroller, resulting in a touch.
 Mutual Capacitance , compared to self-capacitance makes it easier to identify the specific touch
points.

Projected Capacitive Technology
Scanning

Projected Capacitive touch screens are “scanned”, meaning they are made up of a matrix
of rows and columns that are “read” one by one to get a reading or count.
How it Works

To get an exact coordinate, the results from several row/column intersections are read and
the counts are used to triangulate the exact touch location.
Benefits



The touch points are extremely precise and the resolution is usually 1024 by 1024 (ten bit).
Scanning also has an advantage of being free of coordinate drift.
Without the issue of coordinate drift, projected capacitive touch screens do not have to be
calibrated by the end-user.
