Screenless
Display
Introduction
Display without screen
Display directly into retina of
eye
One of the TOP 10 emerging
technologies in IT field.
Types of Screenless Display
Visual Image
SD
Synaptic Interface
Retinal Direct Display
Visual Image SD
Working
◦ Illuminating with lasers
◦ Display in A darkened room
◦ two-dimensional surfaces make 3D View
Example,
◦ Hologram
Working Of Hologram
More about Hologram
Different angles of viewer makes objects from
different perspectives just like real object.
Appear to move as viewer walk and look at
them from different angles.
Changes colors or include views of completely
different objects, depending on how you look at
them.
Virtual Retinal Display
Images are projected directly onto the retina of
eye
Unlike Visual Image SD, no reflection of light is
needed from an intermediate object onto the
retina
The user sees what appears to be a
conventional display floating in space in front of
them.
Schematic Diagram of VRD
Historical Background
The VRD was invented at the
University of Washington in the
Human Interface Technology Lab in
1991.
More about VRD
Contains adaptive optics that correct
irregularities in the eye.
Unlike Visual Image SD, it can be viewed
daytime too
Synaptic Interface
No light---- No Eye Display
Uses Brain computer interface
Image is send directly to brain without
the use of eye
Synaptic Interface - Diagram
Camera
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.
