I. INTRODUCTION
• Screenless display is the present evolving technology in the field of the
computer-enhanced technologies. It is going to be the one of the
greatest technological development in the coming future years.
• Several patents are still working on this new emerging technology
which can change the whole spectacular view of the screenless
displays.
• Screen less display technology has the main aim of
displaying (or) transmitting the information without any
help of the screen (or) the projector.
• Screen less displays have become a new rage of
development for the next GEN-X.

Screen less computing systems can be
divided mainly into 3 groups:
1. Visual image
2. Retinal direct
3.Synaptic interface

2.BACKGROUND
A.VISUAL IMAGE
• Visual Image screen less display includesany screen less image that the
eye can observe as shown in figure 1 and 2. The most public example of
Visual Image screen less display is a hologram

HOLOGRAM:
• Holograms were used mostly in communications as an alternative to screens.
Holograms could be conveyed directly, or they could be stored in various
storage devices.the storage device can be hooked up with a holoprojector in
order for the stored image to be accessed.
• Debatably, virtual reality and heads-up display in jet fighters also are included
in Visual Image category. In all of these cases, light is reflected off some
intermediate object before it reaches the retina.
• In the case of LCD panels the light is refracted from the back of the panel.
• The new software and hardware will enable the user to, in effect; make design
adjustments in the system to fit his or her particular needs, capabilities, and
preferences..

B.RETINAL DISPLAY
• Virtual retinal display systems are a class of screen less
displays in which images are projected directly onto the retina
• They are distinguished from visual imagesystems
because light is not reflected from some intermediate
object onto the retina.
• it is instead projected directly onto the retina. Retinal
Direct systems, once marketed, hold out the promise of
extreme privacy when computing work is done in public
places because most inquiring relies on viewing the same
light as the person who is legitimately viewing the
screen.

C. 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
• While such systems have yet to be implemented in humans, success has
been achieved in sampling usable video signals from the biological eyes
of a living horseshoe crab through their optic nerves, and in sending
video signals from electronic cameras into the creatures' brains.

3. THE WORKING PRINCIPLE
There are several original emergent ways for the technical growth of the
working principle of the screen less displays.
Some software’s are merging for the GEN-X wonder view. Any CPU
system that can run the mudoc software can present text that has been
set in interactive movable type.
Most of the mudocs that are consumed in the next few years will be
consumed with conventional personal computers, e-book readers, and
other kinds of display and projection devices that are now in use
Very soon it appears to be a new kind of input/output system will help
statement and interaction between the computer and the computer
user.

Visual Image can create and Work images of any size: the only control
is the amount of memory resources your system has.
Additional Software and Hardware Requirements:
• To facilitate the interactivity
• To provide the most healthful visual environment
for the user.
• Responding to a variety of user commands (using
voice, hand, foot, or other signal methods)
• Modifying output to compensate for changes in
user’s physiology or reaction time, etc.

4.VIRTUAL RETINAL DISPLAY STRUCTURE
AND IMPLEMENTATION.
A virtual retinal display (VRD), also known as a Retinal scan display (RSD), is a
new display knowledge that draws a raster display (like a television) directly onto
the retina of the eye.
The operator sees what appears to be a conservative show variable in space in
front of them. Like systems have been made by proud a defocused image right in
front of the user's eye on a small "screen", usually in the form of large sunglasses.
The drawback of these systems was the incomplete area covered by the
"screen", the high weight of the small televisions used to project the display,
and the fact that the image would appear focused only if the user was focusing
at a specific "depth".

Incomplete brightness made them useful only in indoor settings as well. Only
lately, a number of developments have made a true VRD system in practice.
Lively enough to be used during the day and adaptive optics have allowed systems to
dynamically correct for wrongdoings in the eye. The result is a high- resolution screen
less display with excellent color range and brilliance, far better than the best TV skills.

5.APPLICATIONS OF THE SCREENLESS
DISPLAY
The main use of the screen less displays are used for the growth of the mobile phones
which are mainly used by the old and unsighted people as this type of the creation of
the screen less displays was first done on the mobile phone named OWASYS 2CC.
This model is very useful for the old, blind, and even for the people with less
dream power.
Hologram projection is a result of a technological revolution that honestly
Latest laser skill are also implementing the singular method of the screen less display
through the company of the some 3D scope animation or the screen provides the
advantage of being united with the Laser Valve Video Projector that helps in
prouduse video images by the use of the laser light instead of the Xenon Arc lamps

Laser skills have given an edge over the other technologies as the LVP gives
the projector an excellent depth in the focus.
Screen less display’s major working principle can also be implemented in the
developing of the new screen less TV’s.
Imagine that watching the TV picture that seems to be strangely looking in the thin
air. The image just floats on in front of the viewer; this would be a latest developing
skill in the upcoming

Low power requirements- Only six diodes are required and a
few of a watts to deliver their images to the user’s eyes
Higher resolution images- The pixels in the images projected
by the diodes can be made smaller than is possible with any
CRT or flat panel display, so higher resolution can be
achieved. With retinal projectors, the only limitation in the
resolution of visual images will be the resolving power of the
users’ eyes.
Greater portability- The combination of diodes, lenses, and
processing components in a retinal projector system will weigh
only a few ounces.
Wider angle of view- Retinal projectors will be able to provide
a wider field of view than is possible with display screens
ADVANTAGES:

DISADVANTAGES:
All has its own advantages and disadvantages. Screen-less display
knowledge has also got some drawbacks.
It’s one of the major drawbacks is non-affordability due to high Cost per
unit.
Another disadvantage is its non- availability in major number as it is still
under growth.
The VRD is still under progress and Development.

6. FUTURE ENHANCEMENTS
For the future development of this emerging new technology,
several researches are being conducted and the several
renowned IT sector companies and other best labs present in
the world are handling over the project of screenless displays
Cool Google is developing the compact video camera which films
everything the wearer looks at and it directly sends the information to
the glasses hence there is no need of any screen or projector.
Multi touch is a human computer interaction technique and the hard-
wires devices which allow the users to compute without unoriginal
input devices.
Japanese scientists have discovered the pair of quick Glasses that
remembers where people last saw their items like: - keys, Handbags,
laptops, and cell phones.

Adobe systems are also working on development and arrangement cross stage
of the several applications which are to be viewed without the real screen
Adobe systems are also working on development and arrangement cross stage

Some laboratories are working under progress on the electron beam lithography which
includes the advanced improvement of the innovative screen less display

6.CONCLUSION:
The paper has attractively discussed screen less displays which
is one of the most developing CPU skills and has become a new
exciting rage for the upcoming generations as a field of the
innovative skill.
Due to the ability of having several compensations which are involved in the
making, designing, coding of the screen less, this needs plenty of information and
process for the development is still under the development.
Screen-less displays look ready to start a generation in the lineage of
projections, and that generation is the screen-less generation
