Dynamo LED Displays installed 3mm pixel pitch LED screens in Sunglass Hut stores across London, including Oxford Street, Westfield Stratford City, Westfield London at White City and Covent Garden. The screens used magnetic front-access modules in a build only 100mm deep, and carried live video from London Fashion Week alongside scheduled store content.

The brief: one LED format for several London stores
Sunglass Hut wanted a video wall behind the counter in its busiest London stores, bright enough to read under shop lighting and fine enough to show faces and product close-ups from a few metres away. The same format had to work in a flagship on Oxford Street, in the two Westfield centres and in a smaller Covent Garden unit, and it had to fit into shop fit-outs where every centimetre of floor depth is stock space.
What Dynamo installed
3mm pixel pitch behind the counter
Each store received a 3mm pixel pitch LED wall mounted behind the till point, where every customer faces it while being served. In 2016 a 3mm pitch was unusually fine for a shop floor, and it meant a model’s face filled the wall without visible pixels from the customer side of the counter. Our indoor LED displays page covers how pitch is matched to viewing distance in a store.

Magnetic front-access modules at 100mm depth
The LED modules were designed to fix with magnets, so any module lifts off from the front for service without taking the wall apart or needing access behind it. That allowed the whole installation to sit at a depth of just 100mm, which matters in a retail unit where the wall behind the counter also backs onto storage. Front access also means a faulty module is swapped in minutes during trading rather than overnight.
Live London Fashion Week content
The walls streamed live video from London Fashion Week during the event and ran scheduled brand content for the rest of the trading day. A live feed is a good test of a retail LED wall: it has to take a video source at short notice and display it without any set-up on the shop floor. Scheduling the normal content means staff never touch the screen; it changes by time of day from the content system, as described on our LED display CMS page.
Current Dynamo options for an in-store LED wall
A wall behind a counter is read from one to four metres, so today we would specify a finer pitch than the 3mm used in 2016. DIT Pro figures are from the supplier specification and DX figures from the DX Series datasheet; all are front serviceable, and DX cabinets are 47mm deep. No prices are given here. The retail LED display buying guide covers sizes, pitches and brightness for shop interiors and windows.
| Model | Pixel pitch | Pixels per 250 x 250 mm module | Brightness | Suited to |
|---|---|---|---|---|
| DIT Pro P1.9 | 1.95mm | 128 x 128 px | 600 nits | Counter-back walls read from one to two metres, product close-ups |
| DX2.5 | 2.5mm | 100 x 100 px | 800 nits or more | Feature walls read from two to four metres |
| DX2.9 | 2.9mm | 84 x 84 px | 800 nits or more | Larger walls viewed from across the shop floor |
| DX3.9 | 3.9mm | 64 x 64 px | 800 nits or more | High-level walls and mezzanines read from further back |

Fine pitch LED in retail stores: frequently asked questions
What LED screens did Dynamo install at Sunglass Hut?
Dynamo LED Displays installed 3mm pixel pitch LED video walls behind the counters of Sunglass Hut stores on Oxford Street, at Westfield Stratford City, at Westfield London in White City and in Covent Garden. The walls used magnetic front-access modules in a 100mm deep build and showed live London Fashion Week video as well as scheduled brand content.
What pixel pitch suits an LED wall behind a shop counter?
Customers stand one to four metres from a counter-back wall, so a pitch between 1.9mm and 2.9mm keeps faces and product shots sharp. The Sunglass Hut walls used 3mm in 2016; today a 1.9mm or 2.5mm module gives a noticeably cleaner close-up picture at a similar cost per screen.
How thin can an in-store LED wall be?
The Sunglass Hut installation was 100mm deep in total, including the structure behind the modules. Current DX Series cabinets are 47mm deep before the mounting frame, so a wall-mounted retail screen can finish close to the depth of a framed picture, leaving the space behind the counter free for stock.
Can an in-store LED screen show live video?
Yes. The Sunglass Hut walls streamed London Fashion Week live during the event, then returned to scheduled content. Any LED wall fed by a video processor will show a live source, whether a broadcast feed, a camera or a games console, provided a signal is run to the processor or the content system supports streaming.
How are front-access LED modules serviced?
Front-access modules fix to the cabinet with magnets. A technician places a suction or magnetic lifting tool on the face of the module, pulls it clear, disconnects the ribbon cable and fits the replacement. Nothing behind the screen is disturbed, so the wall can be built tight to a stud wall or a storeroom partition and still be maintained in minutes.
