SCREENLESS DISPLAYS

INTRODUCTIONScreenless display is the present evolving technology in the field of the computer-enhanced technologies.

Screen less display technology has the main aim of displaying (or) transmitting the information without any help of the screen (or) the projector.

1. VISUAL IMAGE Visual Image screen less display includes any

screen less image that the eye can perceive

Hologram is a technique that records the light scattered from an object, and then present it in a way that appears three dimensional.

WHAT IS HOLOGRAM?

Term used to describe a 3D computer generated environment which can be explored and interacted by a person

VIRTUAL REALITY

2. RETINAL DISPLAYVirtual retinal display systems are a class 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; it is instead projected directly onto the retina.

Retinal Display

3. SYNAPTIC INTERFACE

Synaptic Interface screen less video does not use light at all.

Visual information completely bypasses the eye and is transmitted directly to the brain.

APPLICATIONS OF THE SCREENLESS DISPLAY

Development of the mobile phones which are mainly used by the old and blind people.

Development of the screen less laptops. Screen less TV’s. Widely applicable in the field of hologram

projection Education, medical science, aerospace

and defence.

ADVANTAGES Low power requirements Higher resolution images Greater portability Wider angle of view Ability to present 3D images Greater brightness and better contrast

CONCLUSION

May be 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 the computer technology.
