3. INTRODUCTION
 zForce® is Neonode Inc’s innovative optical 2D
touch technology.
 zForce is an abbreviation for “zero force necessary”
 It gives a number of major advantages compared
with traditional touch technologies, like capacitive or
resistive.
 With zForce, any type of screen or display can be
used.
 In fact, zForce works with any surface – flat, round or
any other shape.
 Another advantage is that any type of object can be
used – a finger or a stylus, a car key, fingernails,
gloves and ordinary pens.

4. HISTORY
 The first ever touchscreen was developed by E.A
Johnson at the Royal Radar Establishment, Malvern,
UK in the late 1960s.
 In 1971 Dr. Sam Hurst, founder of Elographics
developed the first touch opaque sensor “Elograph”
at the University of Kentucky.
 In 1983, Hewlett-Packard introduced the HP-150, a
home computer with touch screen technology.
 In 1993, Apple released the Newton PDA, equipped
with Handwriting Recognition.

5.  In 2001, childhood friends Magnus Goertz and Thomas
Eriksson founded Neonode.
 In 2009, Neonode released the touch-technology zForce
(zero force).
 In 2010, Sony launched their e-reader based on the zForce
technology.
 In the same year, zForce was awarded the title "Best New
Technology of the Year" by the magazine Mobil.
 The technology has been developed since 2011 and is now
implemented into a variety of touch devices such as
tablets and automotive appliances.

HISTORY

6. Types of Touchscreen
ZFORCE AIR TECHNOLOGY | 06

7. Types of Touchscreen
Resistive
 Most widely used in mobile phones.
 Water and dust resistance.
 Touch with fingers, stylus, etc.
 Life span of 35 million touches.
ZFORCE AIR TECHNOLOGY | 07

8. Types of Touchscreen
Capacitive
 More expensive than resistive touch screens.
 Water, dust and scratch resistant.
 Touch only with fingers.
ZFORCE AIR TECHNOLOGY | 08

9. Types of Touchscreen
Infrared
 The most expensive of these three types, these are
however the most resistant kind.
 The major difference is that in spite of using
capacitors across the ends of the screen, infrared
radiations are applied.

10. zForce : A Next Generation Alternative
 zForce technology is
based on light fields.
 As the light is interrupted
by fingers or objects, the
system notes the
position.
Basic Concept
 Other objects than fingers are therefore possible to use,
since the screen responds to any type of material.
ZFORCE AIR TECHNOLOGY | 10

11. Working : zForce Technology
 zForce consists of a set of infrared emitters and
detectors, an optical light guide, control electronics and
control software.
 The emitters pulse infrared light just above the touch
surface.
 A change in detected light indicates an object touch.
 By combining the measured value from more than one
detector, the touch position and object size are
calculated.
 The output from zForce can be used to identify actions
such as gestures and sweeps.
ZFORCE AIR TECHNOLOGY | 11

12.  A plastic light guide is
located under the bezel on
top of the display.
 It serves to reflect and
focus light are shown
attached to an around the
zforce display.
Contd.
 The zforce Technology pulses an infrared light across the screen
at a rate of up to 120 times a second so the grid is continuously
refreshed.
 As the user’s fingers move across the screen, the grid’s
coordinates where the screen is touched are converted into
mathematical algorithms in a process that is unique to Neonode.

14.  zForce has a touch resolution of 250 DPI which enables precision
writing with thin objects such as a pen or a stylus.
 zForce is developed for operating temperatures ranging from
-40°C to +85°C which enables usage in very harsh environments.
 The control software includes, among other functions, advanced
algorithms which calibrate the system by adjusting the power to the
emitters.
 Compensations are made for dust and other small particles on the
surface as well as for variation in component quality and ambient
light conditions.
 Calibration is carried out continuously during normal operation and
no extra calibration is necessary (either in production or by the
end-user).
In Addition.

15. Comparision

16. Application
AirBar
 AirBar projects an invisible
light field all over your
screen. When your finger,
pen or brush breaks the
light, you interact with the
screen without actually
touching it.
 No calibration, no having
to point in special places,
no drama.
 AirBar retails at US$49
(£33)
ZFORCE AIR TECHNOLOGY | 16

17. Advantages
 It does not require a
glass overlay.
 This translates to
better light
transmission and
subsequently better
display quality.
 It does not require
any force.
 It supports
interactions using a
finger, a stylus, or
even a gloved hand.
ZFORCE AIR TECHNOLOGY | 17

18. Other not-so-obvious benefits include the following:
 It is cheaper than capacitive touch screen
solutions
 It supports multi-touch
 It consumes minimal power
 It is not sensitive to Radio Frequency Interference
(RFI) or Electromagnetic Interference (EMI)
 It is able to provide high resolutions.

Advantages
ZFORCE AIR TECHNOLOGY | 18

19.  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.
Limitations

20. Future Scope
 zForce AIR technology present unlimited
opportunities including: car windscreens, home
glass partitions, television displays, automotive
infotainment displays, and foldable displays which
are the future of mobile devices.
 Neonode’s AirBar is planned to be a platform for
enabling other technologies such as virtual reality,
gaming, and mouse functionalities.
 Neonode’s technology for transparent displays can
touch and gesture enable selected sections of the
display at a cost low enough to be applied to a whole
range of devices from entry level to premium models.

21. Conclusion
 Optical touch screens like zForce technology offer a
cheaper and more versatile alternative to more
popular touchscreens like resistive and capacitive
types.
 Neonode zForce is set to replace capacitive touch
screens.
 Back to using infrared bezel sensing touchscreens of
the past.
 Neonode has already licensed zForce to companies
that include Sony and Barnes & Noble.
 So, we can expect to see this technology
implemented into the next generation of phones,
tablets and e-readers.
