ZFORCE AIR TECHNOLOGY | 02

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.


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.

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.

Contd.HISTORY


Types of Touchscreen


Types of TouchscreenResistiv

e Most widely used in mobile phones. Water and dust resistance. Touch with fingers, stylus, etc. Life span of 35 million touches.


Types of TouchscreenCapacitiv

e More expensive than resistive touch screens. Water, dust and scratch resistant. Touch only with fingers.


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.


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.


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.


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.

Working : zForce Technology


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.


Comparision


ApplicationAirBar

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)


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.


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.

Contd.Advantages


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


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.


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.
