this ppt tells about the screenless display,its working ,application and its advantages and disadvantages

1. SCREENLESS
DISPLAY

2.  Screen less display is a present evolving technology in field of
computer technologies.
 Screen less display as the name suggest is a technology that aims
at displaying or transmitting the information without any help of
screen or projector.
 Screen less displays has become a new rage of development for
the next GEN-X.
 Screen less display is mainly divided into 3 groups:
o Visual image
o Retinal direct
o Synaptic interface

4.  Visual Image screen less display includes any
screen less image that an eye can perceive.
 In this case, light is reflected off some intermediate
object (LCD panel, hologram, etc.) before it reaches
the retina.
 The most common example of visual screen less
display is hologram.
 Other examples include lcd panels, tablet
computers and smart phones.

7.  Holograms are used in telecommunication as an alternative to
screens.
 Holograms could be transmitted directly or they can be
stored in various storage devices(such as holo discs).
 The storage device can be hooked up with holo projector in
order to access the stored image.

9.  Visual retinal display systems are a class of
screenless display in which images are projected
directly onto the retina.
 Once marked retinal display systems holds on the
promise of high privacy as retinal display system
sends light only to the pupils of marked person
retina.
 They are distinguished from visual image system
because light is not reflected from some
intermediate image onto the retina; it is instead
projected directly into the retina.

11.  Synaptic Interface screen less video does not use
light at all.
 Visual info directly bypasses the eyes and is
transmitted directly to brain.
 This system has yet to be implemented on humans.
 But success has been achieved in sending video
signals from electronic cameras into the brain of
living horseshoe crab.

13. • There are several new technological developments for the working
principle of screenless display.
• MUDOC software is used for the working of screenless display.
• In future years mudoc software could be installed in our computers,
laptops and other kind of display devices and it would facilitate
communication and interaction between computer and computer
user.
• The working principle of screenless display involves :
• Creating visual catalog file with visual image:
• Visual image give you the ability to create files in eye file format for
use in visual catalog program
• The eye file format creates catalogs of images in logical sub
grouping.

14. • There is a FILE EXPORT PROJECT command that creates eye
file that include all the image that are currently loaded into
visual catalog program. When this command is selected you
are prompted to enter a filename for the eye file that is to be
created.
• The FILE EXPORT EDITOR command allows you to pack and
choose those image that you want to include in catalog file
and thus one can view those images which are included in
catalog files using MUDOC software.

15.  Development of mobile phones which are mainly used by old
and blind people. This was first done in mobile phone named
OWASYS 2CC.
 Screen less display technology is used for development of
screen less laptops. This type of laptops would be very
portable and would be a green solution to landfills.
 Widely used in the field of hologram projection.
 Latest laser technology are also implementing the special
technique of screen less display.

17.  Low power requirement : only six diodes are required and a
few of watts to deliver the image.
 Higher resolution images : the pixels in the images projected
by diodes can be made smaller so higher resolution can be
achieved.
 Great portability
 Wider angle of view
 More accurate color
 Greater brightness and better contrast.
 Ability to present 3d images.

18.  For the future development of this emerging new technology,
several researches are being conducted and several renowned
it companies and best labs around the world are handling
over the project of screen less display.
 MICROSOFT in 2001 began the work on an idea for an
interactive table that mixes both physical and virtual worlds.
 Japanese scientists have invented the glasses that remembers
where people last saw their keys, handbags, ipod, mobile
phones.
 Several laboratories are working on the electron beam
lithography which includes advance enhancements of screen
less display.
 Screen less display promises the cost effective aspect and
also brighter future in the computer application.
