Digital window display: reach passers-by, even when you are closed

A printed poster fades, peels and only changes at the next print run.

A screen behind your shop window shows today’s offer, stays readable in direct sunlight and keeps talking to passers-by once the shutter is down. You change the message from your browser, in minutes.

The experiences involved

Four EMITY experiences, one platform from the pavement to the counter.

01Window display

What a screen changes in a shop window

A shop window is a retailer’s first salesperson: it works around the clock, unpaid. It just has to say something current.

Digital window displays, in practice

A digital window display is a professional screen placed behind the glass and connected to an online platform. You upload your visuals, you decide when each one runs, and the display updates remotely — no reprinting, no ladder.

  • ✓Your current offer, changed in a few minutes
  • ✓A display that stays readable in daylight, even facing south
  • ✓A message that carries on at night, shutter down
  • ✓Video, a carousel or a still visual, depending on the moment

It all runs from E-MANAGER, our digital signage platform: one dashboard, whether you have one window or thirty.

02A window that works

One screen, three uses across the day

These are not three screens but one, with three scheduled contents. The platform changes the display according to the time, with nobody touching it.

Passer-by in bright sunshine in front of the bookshop window: the high-brightness screen stays readable, this week's new children's books, open from 10 am1 · In broad daylightMorning and middayThis is when a shop window is hardest to hold: the sun hits the glass and washes the picture out. A high-brightness screen stays readable where a consumer TV simply disappears.✓Higher brightness, built for glass✓Anti-reflective treatment✓Your new arrivals, changed weekly
Late afternoon, a mother, her child and a passer-by stop in front of the bookshop screen: evening offer and a public reading at 7 pm2 · At peak footfallLate afternoonEarly evening concentrates the passers-by. That is the slot for offers: you schedule the promotion ahead of time and it appears on its own at the right moment.✓Scheduling by time of day✓Offers, sales, events✓Short video or still visual
Bookshop closed at night: the window screen invites people to order online and shows tomorrow's opening time, 10 am3 · At night, shutter downAfter closing timeYour window does not close with the shop. The screen takes over: opening hours, click and collect, out-of-hours number. That is visibility time at no extra cost.✓Opening hours and practical details✓Pointing to your online shop✓Scheduled switch-off if you prefer

03Choosing the hardware

Which screen for which window?

The deciding factor is not size, it is brightness, measured in candelas per square metre (cd/m²). A living-room TV tops out around 300: behind sunlit glass it turns into a black mirror. The full range is on the screens page.

Window situation Brightness to aim for Type of screen What to know
Shaded window, narrow street 700 to 1,000 cd/m² Standard professional display Cheapest option, fine if the sun never hits the glass
Window exposed part of the day 1,500 to 2,500 cd/m² High-brightness display The most common choice on a high street
South-facing, direct sunlight 3,000 cd/m² and above Dedicated high-brightness window display Reinforced anti-reflective treatment and cooling
Large facade, read from afar LED panel Indoor or outdoor LED wall Sized by pixel pitch, not by inches
Static content, very low power Electronic ink E-PAPER display Draws no power while the image stays unchanged
Reading distance2 ma 43-inch is enough

Size follows reading distance

Someone walking two metres away reads a 43-inch display comfortably. To be seen from the opposite pavement or from a car, allow 55 to 75 inches, or an LED panel if the facade is wide. In portrait, the screen takes up less of the glass and still lets people see into the shop.

04Content

What you show in your window

You build the visuals in the EMITY built-in editor — and, if your teams already use them, in Canva or Adobe Express.

FRAMENDOOHadvertisers on your screens

Your shop window may have advertising value.

FRAMEN, an advertising marketplace specialising in DOOH, brings advertisers to screens in busy places. In E-MANAGER, you stay in control: each campaign is approved or refused, ads slot into the playlist at the pace you choose, and every play is proven. A new offer, rolling out at the end of 2026.

do with it

The use changes from one shop to another — and often a whole page is devoted to it.

06Getting started

How it goes in

A first window takes half a day, installation included. The ones after that are duplicated from the platform.

08FAQ

Your questions about digital window displays

Brightness is the deciding factor. A sunlit window needs a high-brightness display; a shaded one is fine with a standard professional screen. At night the problem reverses: too bright dazzles, so the platform automatically dims the display. Since EMITY works with every manufacturer, the choice of model stays open — we advise on it based on how your window is actually exposed.

Three families coexist. The high-brightness LCD covers the large majority of retail windows. The LED panel takes over on wide facades and long viewing distances. Electronic ink suits content that rarely changes, since it draws no power between two image changes. The software is the same in all three cases.

Yes: screen, player, software and support can come together through a certified reseller near you. You do not have to assemble the parts yourself or juggle several suppliers. A 3-month trial lets you measure real usage before committing.

Yes, and it is often the most effective content: a few seconds of movement stop the eye far better than a still image. The platform takes your videos as readily as your visuals, and you alternate them in the same loop. One practical note: a window is watched without sound, so everything has to work through the picture.

It is the use of a shop’s glazed surface as a medium aimed at the street. Historically done with posters and vinyl, it now runs on screens: the message becomes editable remotely, schedulable by time of day, and able to carry video.

The cost breaks down into the screen, the player if the screen is not a connected model, and the software subscription. The subscription is chosen per screen, on the Standard, Premium or Excellence plan, so you can start with one window and extend later. The detail is on the subscriptions page.

Rarely. EMITY is compatible with every manufacturer: a connected Samsung (Tizen), LG (webOS) or Android screen takes the E-SOFT app, and any screen with an HDMI input works with an E-BOX player. The only real limit is brightness: a consumer TV will stay hard to read behind sunlit glass.

No, and that is your call. Time scheduling switches the display off overnight if you want, or leaves it running dimmed on an information loop. For content that almost never changes, electronic ink draws no power between updates.
