3. 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.
5. 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.
7. 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.
10. 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
12. APPLICATIONS:
Education
Health care Training
Improves Security
Applications in Mobile Technology
Hologram projection
Screenless TV’s and Laptops
13.
14. DISPLAY DEVICES:
Google glass
Oculus Rift
Eye tap
Bionic lenses
Head up displays
Sony headman by “sony”
15.
16. 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
17. LIMITATIONS:
The SYNAPTIC INTERFACE display is still under
progress.
Limited availability
Many problems related to the eye sight can
arise.
