Indoor video walls, outdoor screens and billboards, shop-window displays and permanent stage walls for halls, supplied as branded or imported panels and installed by our own crew.
An LED wall is thousands of red, green and blue LEDs on modules, built into cabinets and joined into one seamless screen. How closely those LEDs are spaced, how bright they are and how they are protected decide what the wall costs and where it works.

Anatomy
How an LED wall is built
Each LED holds a red, a green and a blue chip. Hundreds of them sit on a module, commonly 320 × 160 mm. Modules, a power supply and a receiving card fit into a cabinet, and cabinets lock together into a wall of almost any size.
A video processor takes your laptop, camera or media player input and maps it across the wall. For signage, a small player with Wi-Fi, 4G or USB plays scheduled content on its own.
Inside a cabinet
What sits behind the screen
Every cabinet carries its own power supply and receiving card, with power and data looped from one cabinet to the next. Die-cast aluminium cabinets are light, flat and quick to align; steel cabinets are used for large outdoor screens.
Front-service cabinets let modules come out from the front, so a wall can sit flat against your wall with no access space behind it.
Technology
SMD or COB?
SMD screens use LEDs in individual packages. They are the most common, cost less and are easy to repair module by module. COB (chip on board) seals the LEDs under one resin layer: tougher against knocks and dust, deeper blacks and the finest pitches, at a higher price. GOB adds a protective glue coat over SMD LEDs, a middle path for screens people can touch.
Pixel pitch
Sharper is not always better
The pitch is the distance between pixels in millimetres. Halve the pitch and you get four times the LEDs in the same area, and a much higher price. Pay for the pitch your viewers need: as a rule, the closest viewer should be at least as many metres away as the pitch number.
The most common: fixed to a wall or a steel frame, for lobbies, showrooms and halls.
Floor-standing
On its own base frame, for stages and spaces where the wall cannot take the load.
Hanging (flown)
Suspended from the ceiling or truss, for atriums and auditoriums.
Curved and corner
Concave, convex or wrapped around a corner, using curved or angled cabinets.
LED poster and standee
Free-standing, plug-in screens for entrances, counters and malls.
Outdoor billboard and facade
Weatherproof screens on poles, rooftops and building fronts.

Choosing the pitch
Which pixel pitch do you need?
A rule of thumb: the closest viewer should be at least about as many metres away as the pitch number in millimetres.
Distance between pixels in millimetres. Smaller pitch = sharper up close, more LEDs, higher price.
Brightness (nits)
Indoor walls need 600 – 1,000 nits; screens facing sunlight need 5,000 nits or more.
Refresh rate (Hz)
3,840 Hz and above avoids flicker and lines when the screen is filmed on phones or cameras.
Grey scale (bit)
How many shades each colour can show. 14 – 16 bit gives smooth gradients at low brightness.
IP rating
Protection from dust and water. Outdoor screens need IP65 on the front and the back.
SMD, COB and GOB
SMD: each LED in its own package. COB: LEDs sealed under one resin layer. GOB: SMD with a protective glue coat.
Front or rear service
Front service lets modules come out from the front, so the screen can sit flat on a wall.
Video processor
The box that takes your HDMI or other input and maps it to the wall, scaling and switching sources.
Our own LED
Our LED, at work
Every screen here is from our own 4,800+ sq ft of LED, rigged by our own crew. The same stock goes into fixed installations on monthly rent.

Take the LED wall on monthly rent
We install an LED wall from our own 4,800+ sq ft stock on your premises. You pay a monthly rent with maintenance included, month to month, and can upgrade it or buy it out later.
Site surveyWe visit, measure the wall, check the structure, power and viewing distance, and understand what you will show on it.
Recommendation and mock-upYou get the right pitch, size, brightness and a mock-up of the screen on your wall, with options for branded or imported panels.
SupplyPanels, controller, processor and accessories are supplied to suit your budget and the brand you choose.
InstallationOur crew builds the mounting structure, installs the cabinets, runs power and data, and calibrates colour and brightness.
Training and handoverYour team learns to switch it on, change content and schedule playlists.
AMC and supportOptional annual maintenance with checks, cleaning, spare modules and repairs.
Why Solutions AV Systems
Bought from people who run LED walls for a living
29 years of running LED walls
We have rigged and run LED walls since long before we sold one. We have sold 18,000 sq ft of LED walls to dealers, stores and hotels, and own more than 4,800 sq ft that we maintain ourselves, so we know what fails and why.
Branded or imported, to your budget
We supply branded panels or quality imported panels, and explain the difference in brightness, warranty and service honestly.
Survey before quotation
Pitch, size and brightness are chosen after measuring your site and viewing distance, not from a catalogue.
Local service team
Installation, AMC and repairs are handled by our own team based in Kolkata, serving East and North-East India.
Indoor LED video walls from P1.5 to P2.5, outdoor LED screens from P3.9 to P10, LED poster displays and fine-pitch walls for boardrooms, as branded or imported panels.
How much does an LED wall cost?
Indoor P2.5 LED walls start from about ₹5,600 per sq ft for the screen, and outdoor screens from about ₹6,700 per sq ft. Controller, structure, installation and GST are quoted after a site survey.
Do you install the LED wall as well?
Yes. Our own crew surveys the site, builds the structure, installs and calibrates the screen and trains your staff.
Which areas do you supply LED walls to?
Kolkata and West Bengal, Odisha, Bihar, Jharkhand, Assam and the North-Eastern states.
Is SMD or COB better?
SMD is the common, cost-effective choice and easy to repair. COB is tougher and suits the finest pitches and screens people may touch, at a higher price. We recommend one after seeing your site.
Can I rent an LED wall long term instead of buying?
Yes. With fixed installation we install an LED wall from our own stock and you pay a monthly rent, month to month, with maintenance included.
