Question 1

What is pixel pitch and how does it affect which LED wall I should choose?

Accepted Answer

Pixel pitch is the distance between the centers of adjacent LED diodes, measured in millimeters. A smaller pitch means a denser pixel grid, a sharper image, and a higher price. The key rule of thumb: the minimum comfortable viewing distance in meters is roughly ten times the pitch in millimeters. For cinema lobbies and conference rooms, pitches of 1.5-2.5 mm are typical; for outdoor installations, 4-10 mm is common. The interactive configurator on this page will help you find the right pitch for your space and viewing distance.

Question 2

What is the difference between an indoor and an outdoor LED display?

Accepted Answer

Indoor LED displays are optimized for controlled indoor environments. They have lower maximum brightness (more than adequate under controlled lighting) and a finer pitch suited for close viewing distances. Outdoor panels must handle direct sunlight, so they deliver significantly higher brightness and come with robust weatherproofing (IP65 or higher) that protects against rain, dust, and temperature extremes. Choosing the correct category is essential for reliable operation and the best visual result.

Question 3

How large an LED wall do I need for my space?

Accepted Answer

The right size depends on the purpose of the installation, viewing distance, lighting conditions, and the architectural constraints of the space. As a general principle, the image should be readable and visually dominant from a typical viewing position. The interactive configurator on this page lets you enter your space parameters and instantly get a rough specification for resolution, power consumption, and physical dimensions. For a precise design we recommend a no-obligation consultation with one of our engineers.

Question 4

What is the lifespan of an LED wall, and what does maintenance involve?

Accepted Answer

Modern LED panels have a long operational lifespan that depends on the specific technology, intensity of use, and how the display is operated. The keys to a long life are proper brightness management (running unnecessarily high brightness reduces lifespan) and regular preventive inspections. Maintenance includes surface cleaning, checking data and power connections, and replacing any individual faulty LED modules. XC TECH provides service and remote monitoring of installations even after the warranty period.

Question 5

How does an LED wall compare to a traditional projector in a cinema auditorium?

Accepted Answer

A projector throws light onto a screen, and its performance is affected by ambient light - a dark auditorium is essential. A direct-view cinema LED wall is an active light source that generates its own image, delivering extremely high contrast even in conditions where a projector would struggle. Cinema LED installations meet the DCI-P3 color space specification and can replace a traditional projection system, particularly in small auditoriums and premium venues. The right choice depends on room size and both capital and operating costs.

Question 6

What is COB technology and how does it differ from conventional SMD LED?

Accepted Answer

COB (Chip-on-Board) is a technology in which LED chips are encapsulated directly into the substrate without individual plastic housings. The result is more uniform luminance, a more rugged surface (lower risk of damage to individual diodes), and better touch response, which is especially valuable in interactive installations. Conventional SMD technology is proven, cost-effective, and delivers sufficient performance for most standard installations. The right choice depends on durability requirements, pitch, and the intended application.

Question 7

How does the installation and integration of an LED wall into existing infrastructure work?

Accepted Answer

LED wall installation involves preparing the mounting structure, fitting the LED cabinets, running power and data cabling, configuring the image processor, and performing calibration. XC TECH handles the entire process turnkey - from design through supply and installation to commissioning and staff training. The wall connects to a controller that accepts signals from various sources (PC, media player, camera system). Remote monitoring provides continuous oversight of the installation.

Question 8

How much does an LED wall cost?

Accepted Answer

The price of an LED wall depends primarily on the pixel pitch, the total area, and the installation environment. A finer pitch means more LED diodes per square metre and therefore a higher price. Outdoor builds cost more than indoor ones because of their higher brightness and rugged construction. The interactive configurator on this page gives you an indicative price band for your specific dimensions, pitch and environment. The final price always depends on the exact configuration, quantity and installation work, so we recommend a free, no-obligation quote.

Question 9

What is the difference between an LED wall and an LED screen?

Accepted Answer

In practice these are two names for the same technology. An LED wall is a large-format display surface assembled from individual LED cabinets and modules that together form one continuous image. The term LED screen is used as a more general label for the same solution, often for smaller formats or standalone units. In both cases the same selection principles apply: pixel pitch according to viewing distance, brightness according to lighting conditions, and ingress protection according to the installation environment.
