Premium wall-mounted digital signage with a pure flat back design, 28.5 mm ultra-slim depth, native 4K UHD, and front-access service. Built for retail stores, galleries, hotels, corporate spaces, and high-end interiors — with OEM/ODM support for global projects.
Ultra-slim digital canvas mounted flush in a premium interior
Replace static posters and light boxes with dynamic 4K digital content. Our Ultra Slim Digital Signage Canvas Displays combine architectural elegance with commercial reliability — a pure flat back, just 28.5 mm deep, delivering vivid 4K visuals that blend into retail, hospitality, corporate, and gallery environments.
Most wall displays are boxes on a wall. This one is designed to disappear into the space — while keeping the commercial reliability your project needs.
Around 28.5 mm overall thickness for a sleek, lightweight look — minimal visual intrusion on walls and feature areas in high-end retail, galleries, hotels, and corporate interiors.
A completely flat rear structure attaches directly to the wall, achieving an almost zero-gap "digital picture frame" look with no visible brackets or protrusions from the front.
3840×2160 native resolution keeps product images, fine text, and art content sharp — important when customers stand close to a large screen.
High-brightness panel stays clear and vivid in well-lit retail stores, hotel lobbies, and spaces with large windows or skylights.
Front-access service design allows basic maintenance without fully removing the display from the wall — less downtime in busy commercial locations.
Branded enclosure, logo, system, CMS, packaging, and project-level customization — built for distributors, integrators, and multi-location rollouts.
Different spaces have different problems: static posters that date instantly, walls that waste brand impact, information that is out of date by lunchtime. Here is what this canvas display solves in each one.
Problem: printed POS and posters take weeks to roll out chain-wide.
Show new arrivals, promotions, pricing, membership offers, and brand video — updated from one CMS across every store.
Value: consistent visual marketing, faster campaign changes
Problem: flagship spaces look like every other store — wasted brand impact.
Brand story, campaign films, product close-ups, and event posters at 4K scale that make customers stop walking.
Value: stronger brand feel and dwell time
Problem: rotating physical artwork means re-hanging, shipping, and insurance.
Present high-resolution artworks, exhibition information, and event previews in a gallery-quality digital frame.
Value: art presentation without physical handling
Problem: events, menus, and directions change daily — print can't keep up.
Events, meetings, menus, wayfinding, and brand content that update on schedule, per daypart, without reprinting.
Value: better guest experience, lower update cost
Problem: lobby walls and showrooms communicate nothing after opening hours.
Welcome screens, brand video, data dashboards, and internal notices that stay current and on-brand.
Value: walls become a corporate communication channel
Problem: static directories and notices go stale and look neglected.
Wayfinding, announcements, promotions, and queue information delivered in real time, clearly and reliably.
Value: real-time, clear, updatable visitor informationWritten by the Qtenboard Commercial Display Engineering Team · Reviewed by the Senior Project Deployment Lead · Based on completed commercial display projects.
Retail rollout · 4 store formats · 4 phases
A mid-to-premium French fashion brand with 120 stores was reprinting and redistributing window posters to every location — over three weeks per campaign, with regional promotions falling out of sync.
Qtenboard matched hardware store by store instead of chain-wide: 4K video walls and wall canvases for flagship stores, window-facing displays for street-front boutiques, compact canvases for mall counters.
Result: one CMS pushes every campaign to all 120 stores at once; flagship-level brand control at boutique hardware cost.
QSR deployment · 24/7 operation · dayparting
A fast-food chain replaced static menu boards with Qtenboard 4K digital menu boards above the counter — LTOs and combos on one screen, core menus on the others, with dayparting schedules and offline playback so menus never go dark during a network outage.
Industry data referenced in Qtenboard's published QSR guide: digital menu boards raise average order value by 12–18% (Nielsen) and cut operational cost by up to 30% by removing manual poster changes (Networld Media Group).
Result: menu changes from days to seconds; revenue-protecting playback that survives network failure.
Food court · tenant network · real-time promotions
A food court with multiple tenants struggled with static menu boards: price and promo changes took days and required on-site staff at every counter.
Wall-mounted canvas displays with a shared CMS cut menu update time from 3 days to 1 hour and let tenants rotate offers in real time.
Result: tenants reported ~28% higher sales within 3 months; menu management time fell from 15 hours to near zero per week.
Grocery chain · shelf-edge displays · CMS network
A retail chain replaced manual shelf labels with network-managed digital displays showing real-time pricing, promotions, and stock levels, integrated with store inventory and POS data.
Result: manual label replacement cost down 60%; promotional update efficiency up 90%; promotion conversion for featured products up 27% within 3 months.
Getting the size right the first time saves re-mounting, re-wiring, and re-ordering. Start from your wall space and viewing distance.
| Screen Size | Recommended Installation | Typical Viewing Distance | Content Fit |
|---|---|---|---|
| 43" | Boutique stores, corridors, elevator lobbies, small waiting areas | Near to medium | Posters, promotions, brand content, menus |
| 55" | Retail main walls, hotel lobbies, corporate front desks, showrooms | Medium | Video ads, wayfinding, event info, digital art |
Other sizes are available on request for project-based requirements.
Best fit for retail posters, menus, vertical ads, and wayfinding where a tall, narrow format works hardest.
Vertical format supportedBest fit for brand video, welcome screens, wide menu boards, and data display.
Horizontal format supportedThe same series can be supplied for either portrait or landscape installation, matched to each project's requirements.
Confirm before production
Portrait canvas display in a boutique environment
Send us the wall width and height, the viewing distance, and the ambient light conditions. We will recommend the size, orientation, brightness, and configuration that fits — before you spend on hardware.
The picture is the product. Every spec below exists because a real deployment failed without it — glare in bright stores, soft text at close range, or screens that die in month three.
4K canvas display running appetizing, high-detail food content
This is the part that separates a canvas display from an ordinary wall-mounted screen: the back is completely flat, so the display sits on the wall like a framed picture, not a box.
Close-up of the 28.5 mm slim metal profile
Flat back means the rear of the display is completely flat. It mounts directly to the wall with almost no gap, keeping the front clean and the installation looking intentional — the way a premium interior should.
Pure flat back panel mounted flush to the wall
If your team has to visit each screen with a USB stick, the hardware was the easy part. These options exist so multi-location content stays consistent, on schedule, and recoverable.

Deployments stall when basic site details are missing. Have these ready and we can quote accurately, ship the right hardware, and avoid field surprises.
Flush wall mounting keeps the installation clean and secure
Before final deployment, verify content files, CMS, network, player, video output, screen orientation, and panel appearance to avoid ratio, direction, or compatibility issues on site.

4K is recommended when viewers are close to a larger screen, when the display shows detailed product images or text, or when the project requires premium visual quality. FHD may be sufficient for many standard promotional applications.
Selected commercial models can be configured for 16/7, 18/7, or 24/7 operation. The required operating schedule should be confirmed before quotation because it affects panel selection, heat management, and warranty terms.
