INTRODUCTION• Screenless displays,defined as a display

which helps to display and even transmit any information without the aid of screen.

• It is an interactive projection technology developed to solve the problems of device miniaturization.

• This technology has the main aim of displaying(or)transmitting the information without any help of the screen(or)the projector.

SCREENLESS DISPLAYS

VISUAL IMAGE

RETINAL DISPLAY

SYNAPTIC INTERFAC

TYPES:

TECHNOLOGY USED: 1.VISUAL IMAGE

Visual image is a type of screenless display,which recognizes any type of image or thing with the help of human eye.

This display can supply accurate depth cues and high-quality images and videos that can be viewed by the human eyes.

VISUAL IMAGE (contd..)

The main example of visual image is holograms:

TECHNOLOGY USED: 2. RETINAL DISPLAY

Retinal display are those class of displays in which the image is projected directly onto the human retina.

Retinal direct system promises of extreme privacy when computing work is done in public places.

VIRTUAL RETINAL DISPLAY is the technology used.

TECHNOLOGY USED:3. SYNAPTIC INTERFACE

In synaptic interface display the image is projected directly into human brain by bypassing the human eyes.

Success has been achieved in sampling usable video signals from the biological eyes of horseshoe-crab. The video signals from electronic cameras into the creatures’ brain are transmitted using BRAIN COMPUTER INTERFACE

BRAIN COMPUTER INTERFACE

APPLICATIONS:

Education Health care Training Improves Security Applications in Mobile Technology Hologram projection Screenless TV’s and Laptops

DISPLAY DEVICES:

Google glass Oculus Rift Eye tap Bionic lenses Head up displays Sony headman by “sony”

ADVANTAGES:

Low power requirements Higher resolution Greater portability Wider angle of view More accurate color Greater brightness and better contrast Ability to present 3D images Ability to present far-point images

LIMITATIONS:

The SYNAPTIC INTERFACE display is still under progress. Limited availability Many problems related to the eye sight can arise.
