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.

TYPES:

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.

6. VISUAL IMAGE (contd..)
The main example of visual image is holograms:

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

14. DISPLAY DEVICES:
 Google glass
 Oculus Rift
 Eye tap
 Bionic lenses
 Head up displays
 Sony headman by “sony”

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.
