An optical head-mounted display (OHMD) is a wearable device that has the capability of reflecting projected images as well as allowing the user to see through it, similar to augmented reality technology.
In these presentation ,we have discussed about E-paper technology and it's construction,advantages,disdvantages and applications. Also, future scopes of E-paper have been discussed.
A liquid-crystal display (LCD) is a flat panel display, electronic visual display, or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly.
LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden, such as preset words, digits, and 7-segment displays as in a digital clock. They use the same basic technology, except that arbitrary images are made up of a large number of small pixels, while other displays have larger elements.
LCDs are used in a wide range of applications including computer monitors, televisions, instrument panels, aircraft cockpit displays, and signage. They are common in consumer devices such as DVD players, gaming devices, clocks, watches, calculators, and telephones, and have replaced cathode ray tube (CRT) displays in most applications. They are available in a wider range of screen sizes than CRT and plasma displays, and since they do not use phosphors, they do not suffer image burn-in. LCDs are, however, susceptible to image persistence.
The LCD screen is more energy efficient and can be disposed of more safely than a CRT. Its low electrical power consumption enables it to be used in battery-powered electronic equipment. It is an electronically modulated optical device made up of any number of segments filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome. Liquid crystals were first discovered in 1888. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes
E-paper is one of the types of displays, which have a unique property of being flexible. also it acn be used similarly as a paper. the files that need to be accessed on it should be loaded by certain interfaces.
Electronic Paper is also called Electronic ink DisplayUnlike conventional backlit flat panel displays which emit light, E-paper displays reflect light like ordinary paper.It can be described as an easily transportable electronic display device that looks like real paper and can be rewritten millions of times.
E-paper is a portable, reusable storage and display medium that looks like paper but can be repeatedly written on (refreshed) - by electronic means - thousands or millions of times.
E-paper is a revolutionary material that can be used to make next generation electronic displays. It is portable reusable storage and display medium that look like paper but can be repeatedly written one thousands of times. These displays make the beginning of a new area for battery power information applications such as cell phones, pagers, watches and hand-held computers etc.
Like traditional paper, E-paper must be lightweight, flexible, glare free and low cost. Research found that in just few years this technology could replace paper in many situations and leading us ink a truly paperless world.

3. HISTORY
• Cathode ray tube was discovered by Johann Hittorf in
1869 in primitive Crookes tubes.
•He observe that some unknown rays were emitted
from the cathode which could cast shadows on a
glowing wall of tube.
• In 1890, Arthur Schuster and William Crookes
demonstrated cathode ray could be deflected by
electric field and magnetic field respectively. In 1907
Boris Rosing used CRT in the receiving end of an
experimental video signal to form a picture
4. WHAT IS
CATHOD
E RAY
TUBE?
The cathode ray tube (CRT) is a vacuum tube
containing an electron gun (a source of
electrons) and a fluorescentscreen, with
internal or external means to accelerate and
deflect the electron beam.
A fluorescent screen coated with fluorescent
material to show images from X-ray.
5. How CRTS work and display?
A CRT monitor contains millions of tiny red green and blue phosphorus dots
that glow when struck by an electron beam that travels across the screen to
create a visual image in a CRT monitor tube the cathode is a heated filament
the heated filament is a vacuum created inside a glass tube the electrons are
negative and the screen gives a positive charge so the screen glows
6. BASIC CATHOD RAY TUBE
The CRT uses and evacuated glass envelope which is large deep heavy and
relatively fragile
7.
8. LCD
Also Know as Liquid crystal display
• Liquid crystal display is a thin flat panel display deice
used for electronically displaying information such as
text , images and moving pictures.
• LCD is used in computer monitors Televisions
Instrument panes, Gaming devices etc.
• Polarization of light is used here to display objects.
9. Liquid crystals
• Liquid crystals are liquid chemicals in a state
that has properties between those conventional
liquid and solid crystals .That is a liquid crystal
may flow like a liquid but its may be oriented in
a crystal like way.
• Liquid crystal molecules are aligned precisely
when subjected to electric fields as like as in he
way metal shaving line up in the filed of a
magnet .When properly aligned , the liquid
crystals allow light to pass through
10. The most popular liquid
crystal structure is the
noematic liquid crystal
NLC when they are in a
pneumatic face liquid
crystals are a bit like a
liquid their molecules can
move around and shuffle
paste one and other but
they all point in broadly
the same direction
The liquid is normally
transparent but if it is
subjected to a strong
electric field ions moves
through it and disturb the
well ordered crystal
structure causing the
liquid to polarize and
hence turned off opaque
the removal of the applied
field along the crystal
structure to the form and
the material regains its
transparency
11. The polarization property of light is used in LCD screen to
switch its colored pixels of on at the back of the screen there is
a bright light that shines out towards the weavers in front of
this there are the millions of pixels each one made up of
smaller area called Sub pixels they are colored red green or
blue
Each pixel has a polarizing glass filter behind it and another in
front of it at 90°
12. Liquid crystals can adopt a twisted up structure and when we
apply electricity to them they straighten out again this is the key
how LCD display turn pixel
on and off
13. • In between the two polarizing
filters there is a tiny twisted
noematic liquid crystal that can be
switched on or off electrically
• When it is switched on it rotates
the liquid pass through it through
90° effectively not allowing light to
flow through the two polarizing
filters and making the pixels look
dark
14. Each pixel is controlled by a separate transistor that
can switch it on or off many times each second .
It also very the amount of light that pass hence
giving different shades of red blue green to each
Pixels.
Which in result collectively from a image.
