This document discusses screenless displays, which aim to display or transmit information without using a screen or projector. It describes several types of screenless displays including visual image displays, retinal displays, and synaptic interfaces. Visual image displays recognize images through the eye, retinal displays project images directly onto the retina, and synaptic interfaces send information directly to the brain. Examples of screenless displays mentioned are Google Glass and holograms. Screenless displays are used in medical imaging and have potential applications in various sectors. Advantages include accurate colors, high resolution, and low power; disadvantages are the cost and limited availability currently.

3.  Screenless 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
WHY I CHOOSE THIS TOPIC SCREENLESS DISPLAY

4.  The first screen-less
display that needs
mentioning is Google
Glass.
 Google Glass sits on the
face like a pair of glasses,
and on one eye it has a
block of glass that allows
you to see augmented
reality
FIRST SCREEN-LESS DISPLAY

5.  Visual Image Display
 Retinal Display
 Synaptic Interface
TYPES OF SCREENLESS DISPLAY

6.  The visual image is a type
of screenless display,
which recognizes any type
of image or thing with the
help of the human eye
VISUAL IMAGE DISPLAY
 The following is the example of
the visual image display:
 virtual reality goggles

7.  Retinal display as the name itself
indicates the display of image
directly onto the retina.
 Instead of using some
intermediate object for light
reflection to project the images,
 This display directly projects the
image onto the retina.
RETINAL DISPLAY

8.  Synaptic interface means sending information directly
to the human brain without using any light.
 This technology is already tested on humans and most
of the companies started using this technology for
effective communication, education, business
and security system.
Synaptic interface

9. Example of screenless display
 Hologra
m
A three-dimensional image
reproduced from a pattern
of interference produced
by a split coherent beam of
radiation

10.  Screenless displays are used
mainly in medical holography for
medical imaging applications.
 They are expected to find
applications in commercial,
consumer, aerospace & defense,
and automotive sectors.
 They are currently used in
holographic displays
APPLICATIONS OF SCREENLESS DISPLAY

11. ADVANTAGES OF SCREENLESS DISPLAY
 Screenless display provides more accurate
colors, higher resolution images, and wider
angle of view.
 It requires low power and provides higher levels
of brightness & contrast.

12. DISADVANTAGES OF SCREENLESS DIPLAY
 Currently very expensive
 Very limited quantities available
 Uncertainty regarding vision and general
health problems
