For the Louis Vuitton x Yayoi Kusama takeover of Harrods in London in 2023, Dynamo LED Displays supplied the indoor LED mirror screens inside the polka-dot installation and the LED window displays facing Brompton Road, all finished with a high-contrast resin coating so the specially made Louis Vuitton content stayed vivid in daylight and from wide angles.

The brief: polka dots that move
The Louis Vuitton x Kusama collaboration wrapped Harrods in the artist’s dots, from the awnings to an animatronic Kusama figure in a window, and turned the store’s Louis Vuitton space into a mirrored room. The brief to Dynamo was to add moving Louis Vuitton content to that scheme without breaking it: screens that read as mirrors when idle inside, and window screens bright enough to hold their own against Brompton Road daylight outside.
What Dynamo installed
LED mirror screens inside the installation
Inside, Dynamo fitted fine-pitch LED mirror screens to the columns of the mirrored room. A mirror screen puts a reflective front over a direct-view LED panel: with the LED off it reads as another mirror in the room, and when the content plays the image comes through the reflection. Dynamo built the same idea into the Arsenal FC store as sensor-switched “magic mirrors”.
LED window displays on Brompton Road
Outside, portrait LED window displays carried the campaign imagery to the street, with narrow dotted LED strips either side continuing the Kusama pattern. Window screens face daylight through glass, so they are specified brighter than an indoor wall; Dynamo had already fitted the LED tickers in the Harrods windows, so the store’s window constraints were known.
High-contrast resin coating
Every LED surface was finished with a high-contrast resin coating, known as GOB (glue on board). The resin fills the gaps between LEDs, deepens the blacks, protects the diodes from knocks in a busy store, and keeps the picture legible in direct sunlight and from wide angles, which is what a corner window on a London street needs.
Current Dynamo options for retail windows and mirrors
The figures below are from the DX Series datasheet, the fixed-install range Dynamo specifies for retail windows today. GOB coating and mirror fronts are specified per project.
| Model | Pixel pitch | Module | Brightness | Suited to |
|---|---|---|---|---|
| DX1.9 | 1.9mm | 250 × 250 mm, 128 × 128 px | 800 nits or more | Indoor mirror screens and columns viewed close up |
| DX2.6 | 2.6mm | 250 × 250 mm, 96 × 96 px | 800 nits or more | Inward-facing or shaded window bays |
| DX HB2.9 | 2.9mm | 250 × 250 mm, 84 × 84 px | 3,000 nits or more | Street-facing windows in daylight |

LED screens for luxury retail takeovers: frequently asked questions
What is an LED mirror screen?
An LED mirror screen is a direct-view LED panel behind a semi-reflective mirror front. When the LEDs are off the surface reads as a plain mirror, and when content plays the image shows through the reflection. In the Louis Vuitton x Kusama room at Harrods the mirror screens sat on the columns among the real mirrors, so the moving content appeared inside the reflected space.
Which LED screens did Dynamo supply for Louis Vuitton x Kusama at Harrods?
Dynamo LED Displays supplied and installed the indoor LED mirror screens inside the mirrored Kusama room and the LED window displays on the Brompton Road frontage, including portrait screens and dotted LED strips. All of the screens carried Louis Vuitton content produced for the collaboration, and every surface had a high-contrast resin coating.
Why coat LED screens with resin for a store?
The GOB resin coating fills the gaps between the LEDs, which deepens black levels and improves contrast in bright light, and it seals the diodes against knocks and cleaning in a busy store. It also widens the usable viewing angle, which matters for a corner window seen by people walking past at an angle rather than standing in front.
How bright does a Harrods window screen need to be?
A screen facing a London street through glass competes with daylight and with reflections of the street, so it is specified well above indoor brightness. Dynamo’s high-brightness window cabinets are rated at 3,000 nits or more on the DX Series datasheet, against 800 nits or more for the standard indoor cabinets, and the controller dims the screen after dark.
Can LED screens be hired for a short retail campaign?
Yes. A campaign takeover that runs for weeks rather than years can use Dynamo’s LED screen hire service, with the screens installed for the campaign window and removed afterwards. Permanent windows and mirrors, such as the Harrods tickers, are supplied as fixed installations instead.
