WHAT IS A TOUCH SCREEN ?

Touch screen

is an electronic

visual display

that locates the

coordinates of

users touch

within the touch

area.

TOUCH

SCREE

N

types

RESISTIVE

CAPACITATI

VEINFRARED

RESISTIVE TOUCH

Most widely used in mobile phones

Water and dust resistance

Touch with fingers, stylus, etc.,

Life span of 35 million touches

CAPACITATIVE TOUCH

Most expensive than resistive

touch screens

Water, dust and scratch resistant

Touch only with fingers

INFRARED TOUCH

Z-FORCE

Z-Force is developed to work with a wide

range of touch enabled devices such as

smart phones, tablets, toys, home appliances,

e-readers, printer products and automotive

applications.

Z-Force is developed to provide outstanding

performance.

This is achieved through Neonode’s multi

sensing technology

WORKING PRINCIPLE

The frame is Integrated with printed

circuit board.

Contains IR-LED’s & Photo

transistors hidden behind the

bezel.

These are set on opposite sides of the

screen to create invisible IR-light

MULTI SENSING TECHNOLOGY

It performs with the speed of light.

ADVANTAGES:-

It is cheaper technology as compared to

the resistive and capacitative touch screens.

Long service life

It does not use the electrical properties of

the human body to track movement.

Long battery life

Touch con be activated by any thing

including finger, stylus, gloved hand

DISADVANTAGES:-

A raised bezel is placed around

the screen.

1ms response times are quite possible

with this new technology and there is little

to no lag.

CONCLUSION

Neonode could be a solid stock for

technology growth investors. The firm’s

unique technology, solid business model,

near-term revenues and long-term

contracts make it worth a second look.
