Emitters and Detectors for Infrared (IR) Touchscreens

Application note

presents a general overview of different

technologies and their features.

1. Introduction

This paper will give an overview on IR-based

touchscreen technologies with a special

focus on infrared emitting diodes (IREDs)

and photodetectors to be used in such

applications. It shall help touchscreen

designers to select suitable IR components

for their system and provide some general

optoelectronic guidelines.

Touchscreens as a popular user interface

are more and more common. Applications

span from public information systems to

customer self-service terminals. Thus, as a

logical step, more and more devices today

feature this kind of user interface, e.g. bank

automatic teller machines (ATMs), personal

digital assistants (PDAs), mobile phones and

PC displays. The widespread popularity is

actively supported by standard computer

based operating systems, like e.g.

Windows^®7.

Traditionally, IR touchscreens have faced

three criticisms: Size, cost, and ambient light

sensitivity. The first two concerns stem from

traditional matrix-based systems. However,

new technology and slim packages enable a

significant decrease in bezel height

combined with a decrease in cost. Camera-

based systems go even further by reducing

significantly the number of parts at the cost

The rapid development of CMOS imaging

sensors and the development of high power

infrared (IR) emitters in slim packages have

led to a series of new optical touchscreen

technologies. Many of them contain

proprietary technology and solutions. Tab. 1
