2. What is screenless display
technology
Screenless Display Technology is a system of
transferring information/data through an
electronic video source without using screen.
Screenless Display technology has the main aim of
displaying or transmitting information without any
help of the screen (or) the projector.

3. Basic Display of SDT

4. Three part division of SDT
The SDT is divided into mainly three parts i.e.
there three main concepts used in SDT.They
are as follows:
 Visual Image
 Retinal Direct
 Synaptic Interface

5. 1. Visual Image
• Visual Image Screenless Display includes any
screenless image that the eye can perceive.
• These system works by focussing a laser beam
that generates a plasma environment from
the oxygen and nitrogen present in air, thus
displays holographic images i.e. 3D floating
objects in mid air (3D technology).

6. Display of Visual Image:

7. 2. Retinal Direct
• Virtual display systems are a class of
screenless displays in which images are
projected directly onto the retina .
• In 3D technology user requires glasses to wear
in order to view the 3D image but by inserting
Retinal Display technology user don’t require
any glasses to view any image.

9. 3. Synaptic Interface
• Synaptic Interface is a concept which is based
on Brain-Computer Interface.
• The working of BCI is that it creates the
pathway between the brain and an external
device.
• This concept helps the computer to read and
interpret signals directly from the brain .

10. Display of Synaptic Interface:

11. Working Principle of SDT
• Working of Screen less Display Technology is
based on its three concepts i.e. Visual Image,
Retinal Display and Synaptic Interface.
• The technology allows synaptic interfaces that
bypasses the eye altogether, transmitting
visual information directly to the brain.
• We can see things because when light
bounces on an object and enters our eye; light
focuses on the retina to form an image.

13. Applications of SDT
• Mobile Technology
• Hologram Projections
• Latest Laser technology
• Magical Air Display

15. Future Enhancements
• In the future the world may be dominated
with the screen less display technologies and
this enriches the world of technological
empowerment in the field of computer
technology.
• Screen less displays promises the cost
effective aspect and also brighter future in the
information technology.
