LCD and LED are the two most used digital display these days. LCD video wall offers higher resolution compared to the LED video wall. The LCD video wall is only for indoor, but LED is for both environments, indoor and outdoor displays. Know more features about LCD and LED.

1. LED BACKLIT LCD WALL
VS
TRUE LED VIDEO WALL

2. TYPES OF VIDEO WALL
¢ Primarily Three Types of Video Walls
— LED Backlit LCD Video Wall
— TRUE LED Video Wall
— Rear Projection (Cube) Video Wall (Not discussed in this
document)
TRUE LED VIDEO WALL REAR PROJECTION

3. LCD LED VIDEO WALL BASICS
¢ LED LCD Video Walls are:
— LCD Video wall have Liquid crystal front layer with
¢ CCFL backlight (Old technology)
¢ LED backlight (New technology)
— These are wrongly called as LED Video Wall
— We will call them LCD Video Wall in this presentation
— Manufactured by Samsung / LG / Sharp / Panasonic

5. TRUE LED VIDEO WALL BASICS
¢ Made up of individual modules with surface mounted pixels
which are clusters of red, green & blue LED’s
¢ When the signal is given, the red, green & blue LED’s will
give an output in the combination of the required display
colour for each pixel to generate the final image
¢ Directly designed, manufactured & maintained by us for the
last 25 years

7. COST OF OWNERSHIP
¢ Typical life of 7-10 years
¢ 3 years warranty &
Comprehensive AMC
thereafter for as low as 8%
¢ Individual pixels/modules
can be replaced/repaired
¢ Comprehensive AMC
which includes all parts
¢ Typical life of 3-5 years
¢ Company warranty for 3
years, expensive AMC
thereafter
¢ In case of damage / failure
whole panel needs to be
replaced
¢ Expensive accessories like
scalar / switcher / video
processors / cables required

8. MAINTENANCE
¢ Front panel is glass
(delicate) & needs
moisture free air
conditioned environment
¢ Incase of panel damage or
failure entire panel needs
to be replaced
— Increased downtime
— Increased Cost
¢ Company warranty -
Lengthy and cumbersome
¢ Ruggedized - IP-65
protection for extreme
weather conditions
¢ Modularized – Onsite
replacement - Reduce
downtime, reduce cost
¢ In-house maintenance

9. BRIGHTNESS
¢ Lacs of LED’s emitting light
¢ Light source i.e. LED’s are directly
exposed to the viewer
¢ No reflection problem as no glass in
front
¢ >= 2000 cd/m2 (nits) for Indoor range
and >= 7500 cd/m2 (nits) for outdoor
¢ Low decay factor
¢ 100s of backlight LED/CCFL
¢ Light source is behind a glass panel
¢ Even after AR coating reflection can
not be avoided due to glass frontage
¢ Presence of reflecting surface and low
non self illuminating crystals causes
low level of brightness in LCD
— Higher brightness panels have 700 nits per
panel (Not per m2)
¢ High decay resulting in low brightness

10. WEATHERPROOF
¢ Completely weatherproof
solution(IP 65) viewable
under direct sunlight
¢ Do not get affected because
of rain fog or sunlight.
¢ Resin coated body bears
harsh weather conditions.
¢ Electronic components like
chips, circuits and other
components gets affected
due to harsh weather
conditions in LCD.
¢ Needs moisture free air-
conditioned environment

11. SEAMLESS
¢ Led video wall gives the
continuous output of the input
picture
¢ Individual video panels are
tiled together with some bezel
gap which obstruct the
display content
TRUE LED VIDEO WALL LCD LED VIDEO WALL

12. CONTRAST LEVEL
¢ True color replication and
high contrast.
¢ As led are readily exposed
to the eye it is more
effective than LCD.
¢ True colour replication is
not possible as light source
is not exposed to the
viewer
¢ Gets affected by ambient
light and glass reflection
from the panels.

13. RESOLUTION
¢ LCD LED video wall offers higher resolution compared to
True LED video wall
¢ Resolution is not important when
— Screen size is very big - All details will be blown anyway
— Screen is to be viewed from a distance (>6 feet) – Minute
details wont be seen anyway
— Input video source doesn’t support resolution of the screen
¢ 3x3 Full HD LCD LED video wall needs input source of 1920*3
x 1080*3 = 5760 x 3240 input content (not practical) else you
are not making use of the resolution anyway
¢ Resolution is important when
— Minute details are to be seen from very close distance
— Examples
¢ Small Board Rooms
¢ CCTV Control Room

14. APPLICATIONS
¢ Indoor applications where ambient light is bright
E.g. It can be used in lobby, malls, stock tickers, product
display, clubs, multiplexes, corporate lobbies, etc.
¢ All outdoor applications as it is completely weatherproof
and viewable under direct sunlight.
¢ No other digital medium is more suited the following
purpose:
E.g. Bill board, scoreboard in sports arena or stadium,
airport, retail mall, highways, petrol pumps, lobbys, etc.

15. LCD APPLICATIONS
¢ LCD video wall can only be used for indoor applications
where display resolution is important such as control
rooms, board rooms, etc
