What is Screen less Display?
Present evolving technology in the field of the computer-enhanced technologies. To transmit any information without the aid of screens.The countdown for the first screenless display has started now currently from the month of May 2014 onwards.

3 Groups of Screen less technology
Visual image Retinal direct Synaptic interface

VISUAL IMAGEThe eye or the retina can recognize any screen less image.Principle - light gets reflected by the intermediate object before reaching the retina.The intermediate object can be holograms, windows, or even LCDs.

VIRTUAL RETINAL DISPLAY
Allowing the image directly to be projected on to the retinaNo real image is produced It uses narrow band colorCoherent light Allows short transient light emission

SYNAPTIC INTERFACEThe visual image is directly given to the brain.Success in sampling video signals from eyes of horseshoe crab through their nerves. Brain-computer Interfaces - direct communication between the brain and the external device.

DISADVANTAGES
Prototypes and special experimental models are now being built, but their cost per unit is high.The VRD technology is still under progress and Development.

ENHANCEMENT PROJECTS
Microsoft in 2001 began the work on an idea for an Interactive table that mixes both physical and Virtual worldsMulti touch - a human computer interaction techniqueJapanese scientists have invented the pair of intelligent Glasses that remembers where people last saw their keys,Handbags, iPod, and mobile phones.Google Glass
