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.
