1985 SENSOR FRAMEFirst touch screen computerTOUCH SCREENtypes RESISTIVECAPACITATIVEINFRARED

RESISTIVE TOUCH Most widely used in mobile phones

Water and dust resistance

Touch with fingers, stylus, etc.,

Life span of 35 million touches8

CAPACITATIVE TOUCH Most expensive than resistive touch screens

Water, dust and scratch resistant

Touch only with fingers

INFRARED TOUCH

11 Z-forceZ-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 Neonodes multi sensing technologyWORKING PRINCIPLEThe frame is Integrated with printed circuit board.

Contains IR-LEDs & 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 hand16DISADVANTAGES:- 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 firms unique technology, solid business model, near-term revenues and long-term contracts make it worth a second look.
