What is Pixel Pitch?

The spacing between the pixels.

This determines how densely the pixels are packed, which affects image resolution and viewing distance.

Fine Pixel Pitch (FPP) <2mm

(LED Pixel Pitch in mm) The LED screen resolution is opposite proportional to the Pixel Pitch

Minimum viewing distance general rule: the pixel pitch x1000 Optimum viewing distance general rule: the displays width or height. Eg 10m wide screen should be viewed from 10m back for the eye to take in all the information on the screen.

LED Technology Types Understanding LED technology types is key to selecting the right solution for your environment.

Different manufacturing methods impact durability, image quality, viewing distance, and long-term reliability. We design solutions using the most appropriate technology for the application—whether that’s a high-impact reception display, lecture theatre, or high-traffic public space.

SMD (Surface-mounted device)

COB (Chip-on-Board)

Forms the back-bone of most modern LED walls. Each pixel is made up of red, green & blue diodes mounted directly onto the surface of the panel.

Mounts multiple LED chips directly onto the board and covers them with a protective layer, creating a smoother, more durable surface.

Proven, cost-effective solution Excellent brightness and colour performance For meeting rooms, classrooms & auditoriums Available across a wide range of pixel pitches

Improved durability and impact resistance Reduced risk of LED damage or failure Better heat dissipation for longer lifespan Ideal for high-use environments

GOB (Glue-on-Board)

HOB (Hybrid-on-Board)

Adds a transparent protective coating over traditional SMD LEDs, enhancing durability without significantly impacting image quality.

Combines the benefits of SMD and COB, offering improved protection while maintaining high brightness and colour performance.

Protection against dust, moisture & damage Easy to clean and maintain Suitable for public & high-touch environments More robust than standard SMD

Enhanced durability, no compromise on clarity Improved viewing angles Balanced performance for mixed-use environments Increasingly popular in education & corporate

MIP (Micro-LED-in-Package)

An emerging technology that packages extremely small LED chips into compact modules, delivering exceptional image quality.

Ultra-fine pixel pitch for close viewing distances High contrast and colour accuracy Future-proof, premium solution Ideal for flagship spaces & high-end applications LED Technology Types | consult@rocheav.co.uk | 01422 310 193

In summary While SMD remains the most common & cost-effective option, newer technologies such as COB, HOB and MIP are rapidly gaining traction — particularly where durability, image quality, and longevity are key considerations.

Custom LED Displays

Customisable LED displays provide the ultimate level of flexibility, enabling fully bespoke solutions tailored to your space, application & visual requirements. Unlike All-in-One LED, which is delivered in fixed sizes & formats, custom LED walls are built from individual cabinets, allowing complete freedom over size, shape, resolution & performance. We design and deliver fully bespoke LED solutions that align precisely with the environment - whether that’s a large lecture theatre, immersive teaching space, reception feature wall, or high-impact corporate installation.

Key Benefits of Custom LED Custom LED solutions are designed for projects where standard display sizes or formats are not sufficient, offering complete control over both performance and aesthetics.

Bespoke Sizing: can be built to virtually any size or aspect ratio, ensuring it fits the space perfectly.

Flexible Resolution & Pixel Pitch: Choose the ideal pixel pitch based on viewing distance & content.

Choice of LED Technology: Select from SMD, COB, HOB, or emerging technologies.

Creative Designs: concave/convex curved installs, ultra-wide formats & non-standard shapes.

Internal & External Use: High-brightness / weatherproof for external facades, signage & displays.

Scalable Performance: Brightness, refresh rate & processing can be specified to suit the use case.

Seamless Visual Experience: No bezels / visible joins, delivering an immersive, uninterrupted image.

Future-Proof: Modular design allows for component-level maintenance, upgrades and expansion.

Why Choose Custom LED? The ideal solution where impact, flexibility & precision matter most. It allows organisations to design a display around their exact requirements rather than adapting their space to fit a fixed-size LED. From flat walls to fully curved installs & from internal spaces to external high-brightness signage, custom LED provides a scalable, future-ready platform that can evolve alongside your needs.

All-in-One LED Displays

All-in-One (AIO) LED displays represent the next evolution of LED technology, combining performance, simplicity, and speed of installation into a single, integrated solution. Unlike traditional modular LED walls, All-in-One systems are pre-configured and designed for rapid deployment with minimal infrastructure requirements. As highlighted across our LED installations, LED technology already offers seamless visuals, high brightness, and long-term reliability—All-in-One builds on this by simplifying the entire deployment process.

Key Benefits of All-in-One LED Designed to remove the complexity traditionally associated with LED installations, making them ideal for education, corporate, and public sector environments.

Lightweight Design: Slimline, pre-built cabinets significantly reduce wall loading requirements.

Single Power Source: Typically powered from a standard socket, no complex electrical infrastructure.

Rapid Installation: Delivered as a complete system, allowing installation in hours rather than days.

Integrated System Components: Built-in controller/audio/OPS reduces need for additional hardware.

Clean, Minimal Aesthetic: Designed to look like a large format display rather than a traditional video wall.

Front Maintenance Access: Modules can be serviced from the front, reducing downtime.

Scalable & Future Ready: Offering flexibility while maintaining a simplified deployment model.

Flexibility for a wide range of spaces: Common sizes include 108”, 136”, 163”, 180”, 217” and 220”.

Why Choose All-in-One LED? Provides the visual impact of a traditional LED wall, without the complexity. It bridges the gap between large format displays & fully bespoke LED builds - delivering a premium solution that is faster to deploy, easier to maintain & more accessible from a budget & infrastructure perspective.

LED vs LCD vs Projection NEW LED

OLD LCD

Case Study - University of Sunderland swapped LCD video walls for LED walls When selecting a large format display solution, organisations typically choose between LED, LCD video walls & projection systems. Each technology has traditionally been associated with different price points & performance levels. However, with the evolution of All-in-One LED solutions, this landscape has changed significantly. LED is no longer a premium-only option - it is a commercially viable alternative that often aligns closely with the cost of high-performance projection & video wall systems. At Roche AV, we support customers in selecting the right solution based not only on upfront cost, but on long-term value, usability, and performance.

LED Displays: now widely considered the most future-ready display technology.

Seamless image: no bezels or joins High brightness: consistent in all lighting conditions Long lifespan with minimal maintenance requirements All-in-One solutions reduce install/infrastructure costs Now cost-comparable to high-end projection systems With the introduction of All-in-One LED, organisations can achieve large-format displays without the complexity or historic cost barriers traditionally associated with LED. LCD Video Walls: use multiple LCD panels tiled together to create a larger display surface.

Moderate upfront cost Good image quality suitable for standard applications Visible bezels between panels can interrupt the image Requires precise installation and alignment Ongoing maintenance and panel replacement over time While cost-effective initially, video walls can become less attractive when considering long-term maintenance and visual limitations.

LED vs LCD vs Projection | consult@rocheav.co.uk | 01422 310 193

Projection Systems: historically the go-to solution for large image sizes in large venues.

Traditionally perceived as the lowest cost for large displays Suitable for controlled or low-light environments Simple concept, but very complex at higher performance levels

For large, high-brightness applications, costs increase significantly. For example: A large venue projector capable of producing a 4.8m wide image at 25,000 ANSI lumens can typically cost in the region of £30,000 (excluding full installation and infrastructure) This compares to a 217” All-in-One LED, which delivers superior brightness, clarity & reliability Additional considerations include: Image quality impacted by ambient light, Ongoing maintenance (laser/lamp servicing, filter cleaning), Alignment and calibration requirements and Ceiling mounting and line-of-sight constraints

Which Should You Choose?

While projection and video walls still have their place, the gap between technologies has narrowed significantly. As a result, many organisations are now choosing LED not as a premium upgrade—but as a like-for-like alternative that delivers greater long-term value.

With the introduction of All-in-One LED, organisations can now achieve: Comparable upfront cost to high-end projection Superior image quality in all lighting conditions Reduced maintenance and operational overhead A more flexible, future-proof display solution
