3. INTRODUCTION
 ‘SCREEN LESS DISPLAY’ As the name implies
the display of several things without the use of
screens using projector.
t is one of the TOP 10 emerging technologies in IT
 It is the one of the top 10 emerging
technologies in IT field.
 We will be using Screen less display technology
during 2020’s

4. Types of screen less displays
 It involves the following 3 different working
principles.
1. Visual image.
2. Virtual retinal display.
3. Synaptic interface.

5. VISUAL IMAGE screen less display
 Visual Image screen less display includes any
image that the eye can perceive.
 It is made by illuminating with lasers or display in
a darkened room with carefully directed lighting.
 EX: hologram, LCD panel & cockpit window.

6. HOLOGRAM
 Hologram is a photographic recording of a light
field, rather than of an image formed by a lens.
 It is used to display a fully 3-D image of subject,
which is seen without the using of any special
glasses.
 These are saved in HOLOLOIDS.

7. Working principle of hologram

8. Products using HOLOGRAM
air touch
system.

9. VIRTUAL RETINA DISPLAY
 Virtual retinal display systems are a type of
screen less displays in which images are
projected directly onto the retina.
 They are distinguished from visual image
systems because light is not reflected from
some intermediate object onto the retina
 As the video falls directly on to retina of
a intended viewer it is highly secured.

10. VIRTUAL RETINA DISPLAY
•Virtual retinal display systems are a class of screen
less displays in which images are projected directly
onto the retina as shown in below figure.

11. Working of VRD

12. APPLICATIONS:

13. SYNAPTIC INTER FACE
 Synaptic Interface it is the interface b/w brain
and eye.
 Visual information completely bypasses the
eye and is transmitted directly to brain.
 While such systems have yet to be
implemented in humans.

14. Camera sends
images to electrode
implant

15. ADVANTAGES
 Wider angle of view- Retinal projectors will be
able to provide a wider field of view than is
possible with display screens.
 Greater brightness and better contrast-
Retinal projectors can provide higher levels of
contrast and brightness than any other display
system.

16. DISADVANTAGES
 The principle disadvantage is that Virtual
retinal display (VRD) is not yet available in the
significant number.
 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.

17. CONCLUSION
 The future technologies makes our life even
better for the development of mankind in all
aspects of life.
 We should effectively apply these technologies in
reasonable situations and make life easier.
 Physically and Mentally challenged people also
have to be equipped with latest technologies, to
enable them to live a peaceful life.
