Plan for the viewing distance
Screen size, pixel pitch, and mounting placement are matched to how close customers and staff stand and how long they have to read a message.

Indoor Displays
Keep guests and customers informed inside the business.
Indoor digital window displays keep guests, customers, and teams informed inside the business, with a message that can change as often as it needs to.
The short answer
Indoor digital displays show changing messages to people inside or just outside a business, often through a window. Because viewers stand close, they need a finer pixel pitch than outdoor signs, and finer pitch costs more. Check whether your city treats a street-facing window display as a sign.
Best fit
Designed around the way your site gets seen.
- Indoor digital window displays
- Businesses that update offers, hours, or announcements often
- Locations where a permanent sign cannot carry a changing message
- On-site software and communications training
Planning factors
Options & planning.
Every recommendation is shaped around the site, the audience, the business identity, and the practical path to installation.
Fit the display to the space
Power, mounting surface, and the site are reviewed so the display fits the interior the same way an outdoor display is planned around its location.
Train your team on site
Every digital sign order includes on-site training for the software, communication setup, scheduling, and the everyday tools your team will use to keep the display current.

Buyer’s guide
What to know before you buy.
Straight answers to the questions buyers ask most, with the sources behind every figure.
What pixel pitch does an indoor display need?
Finer than outdoors, because viewers are close. The finer the pitch, the closer people can stand before they see individual pixels, and the more the display costs. AVIXA's visual acuity formula puts that distance at about 45 feet for a 4 mm display, so close viewers see pixels unless the pitch is finer.
Plan from the closest regular viewer: someone at a counter, a window shopper on the sidewalk, or a driver in a drive-through lane.
Are window displays regulated like outdoor signs?
Sometimes. A display facing out through a window can count as a sign under local code. Spokane, Washington, for example, states that illuminated signs placed in windows are subject to its sign regulations in residential zones. Ask your city before you mount a bright display facing the street.
A window display also competes with daylight on the glass. Ask for the display's rated brightness in nits and whether it dims automatically, so it reads at noon without glaring at night.

What does an indoor display cost?
We could not find a neutral national cost guide for indoor LED window displays, so this page gives no range. Size, pixel pitch, mounting, the player and any software subscription set the price. Ask for a quote that lists each of those separately so two proposals can be compared.
Before the first conversation
Before we talk.
A few real details from the site make it easier to compare the right sign directions and define a practical next step.
- 01
Map the audience position
Show where customers or staff stand, how close they are, and the path through the interior.
- 02
Define the message rhythm
List the information that changes and name the team member who will schedule and maintain it.
- 03
Confirm the installation area
Share the mounting surface, available power, nearby light conditions, access, and timing you know.
If you do not have every detail yet, start with the address, a few photographs, and the visibility problem you want the sign to solve.

Common questions.
Can an indoor display share content with an outdoor sign?
Yes. Indoor and outdoor digital displays can be planned together so messaging stays consistent across the business.
What do you need for an indoor display quote?
Share the space, mounting location, viewing distance, and what the display needs to communicate.
Can an indoor display share content with our outdoor sign?
Yes, if both run on compatible software. Planning them together keeps offers and hours consistent. Every Suntronix digital sign order includes on-site software training.
How close can people stand to an indoor LED display?
It depends on pitch and content. AVIXA's visual acuity formula (pitch x 3,438) puts the point where a 20/20 viewer stops seeing pixels at about 45 feet for 4 mm. Large text stays readable closer than that; photos need a finer pitch for close viewers.
Do window displays need a permit?
In some places. Some codes treat illuminated window signs as regulated signs; Spokane does in residential zones. Check with your planning office before mounting a display that faces the street.
What does an indoor digital display cost?
It depends on size, pixel pitch, mounting and software. We did not find a neutral national cost guide for indoor LED displays, so no range is given here. Ask for a quote that separates the display, player, mounting and any subscription.
What happens after I reach out?
Suntronix reviews the location, visibility needs, timing, and business goals before shaping a concept and quote.
Can I send a logo or site photo?
Yes. The quote form accepts a JPG, PNG, or PDF up to 5 MB so the team can understand the project sooner.
