How Glass Mullions, Window Frames and Door Reveals Change an Indoor Transparent LED Film Quote

Quick answer

For an EA250INV indoor invisible LED film display, the supplied passage documents direct mounting on suitable indoor glass without a conventional steel support frame and lists 1,000 × 250 mm, 1,200 × 250 mm and 1,500 × 250 mm modules. It does not document mullion trimming or reveal detailing. Ask the supplier whether the actual mullion, frame and door-reveal layout needs a module quote for each glass area, and confirm edge treatment, cabling and spares in writing before comparing totals.

What the EA250INV Evidence Documents on Indoor Glass

EA250INV is documented as an indoor invisible LED film display for glass walls and storefronts, designed for indoor glass installations and listed for retail windows, shopping malls, exhibition halls, museums, showrooms and creative commercial displays. The film mounts directly to suitable indoor glass surfaces and does not require a conventional steel support frame. Module size and pixel pitch are to be selected according to viewing distance, glass dimensions, brightness requirements and content detail. That is the documented scope the quotation starts from; it is not a mullion, frame or reveal specification. If a cabinet-based option is also on the shortlist, use the transparent film or cabinet comparison to frame the mounting choice before pricing either.

The same passage lists module sizes of 1,000 × 250 mm, 1,200 × 250 mm and 1,500 × 250 mm, and states that available combinations vary by pixel pitch. Each module is 2 mm thick and weighs approximately 1.3–1.5 kg depending on module size. P3.91, P6.25 and P10.42 pitches are offered, with pixel densities from 9,216 to 65,536 pixels/m². Those are the documented building blocks the quotation must name. Whether a glass plane divided by mullions can use them without change is a question for the supplier, because the passage does not settle mullion, frame or reveal handling.

Mullion, Frame and Reveal Questions to Put in Writing

Ask the supplier, in writing, how the quoted EA250INV film is handled where a mullion, window frame or door reveal meets the film area. The passage does not document mullion trimming, film cutting, custom module widths or an edge profile for frames, so the answer belongs in the written project scope rather than in an assumption. Useful questions are whether the quote uses the documented module sizes only, whether any trimming or custom part is proposed, and what is included at each edge. Our advice is to keep that answer on its own quotation line so a blended total cannot hide it.

Frame and reveal dimensions belong on the same sheet. Request the aperture dimensions of each glass area, the frame or reveal detail, and the proposed edge treatment, and ask whether the supplier needs a clearance dimension at each edge; the EA250INV passage does not state a required frame clearance for the film. Also ask whether the answer changes if a glass area is narrower than the smallest documented module size. Those are scope questions, not documented product behaviour.

Quotation Lines to Clarify for a Mullion-Affected EA250INV Layout

Transparency, Module Size and Pitch as Named Quotation Inputs

Transparency should be tied to the configuration, not treated as a model headline. EA250INV transparency ranges from 70% to 90% by pixel pitch and configuration, and the model is described as combining up to 90% transparency with a 2 mm profile. Configurations also provide brightness from 1,500 to 4,500 cd/m², a contrast ratio up to 9,000:1, 16-bit grayscale and a refresh rate of at least 3,840 Hz. Ask for the exact figures that apply to the selected pitch and module combination. A related EA250INV pitch and transparency guide sets out a selection method for the glass storefront.

Module size and pitch interact in the quotation. The three documented module sizes are 1,000 × 250 mm, 1,200 × 250 mm and 1,500 × 250 mm, and available combinations vary by pixel pitch. Pixel densities run from 9,216 to 65,536 pixels/m² across P3.91, P6.25 and P10.42. Ask the supplier to state, for each glass area in the quote, which module size and pitch apply and whether that combination is a documented one. That is a configuration confirmation rather than a claim about how mullions affect the layout.

Power, Data and Service Are Separate Scope Questions

The EA250INV passage does not set out a cable route, a power location or a service sequence for a glass installation. Treat power and data routing as its own line. Ask how the film is fed power and signal, whether any drilling or surface penetration is proposed, whether trunking or protection is included, and how a section is reached for replacement after installation. Those are procurement questions; the passage documents direct glass mounting, not a wiring or service method.

Ask whether a door reveal, frame or mullion affects the proposed routing or the access needed during service, and whether the supplier’s answer assumes one continuous glass plane. If lifting or access equipment is needed, list it separately. Spares belong in the same discussion: ask for spare modules matched to each module size and pitch actually quoted, since documented combinations vary by pixel pitch.

How to Compare Quotes for a Mullion-Affected Glass Layout

Request an itemised quotation rather than one blended total. The display line should state EA250INV, the pixel pitch, the module size or sizes, the transparency for the selected configuration and the module quantity for each quoted area. Then add separate lines for edge treatment at mullions and frames, mounting, power and data routing, control, spare modules, freight and commissioning. Separating the lines is our purchasing advice; it lets a buyer see what each offer actually includes. A useful review method is to compare LED screen quotes line by line.

Build the comparison so every offer answers the same rows: pitch, module size and quantity, transparency, edge treatment at frames and reveals, cable route, service access, spares and delivery. Where an offer gives only a total glass area, ask it to restate the scope by glass area. For the record, the EA250INV passage does not set prices; it documents the product facts that should appear against the quoted configuration.

When to Defer the EA250INV Film Order

Defer the order if the glass area dimensions, mullion positions, frame clearance, door reveal details or glass suitability are unresolved. The passage says the film mounts directly to suitable indoor glass surfaces, which makes suitability a project-specific condition. Ask who confirms that the actual glass is suitable and what review is included.

Also defer if the exact transparency or module combination is not stated. Transparency ranges from 70% to 90% by pixel pitch and configuration, and module combinations vary by pitch. Fix the configuration, edge handling and service route before comparing totals. If EA-iFilm2 is also under consideration, the EA-iFilm2 quotation inputs guide covers its separate glass-mounting lines.

Scenario and What to Confirm First

Buyer checklist

• Measure each glass area and record mullion, frame and door reveal positions before requesting a quote.
• Ask for a written module map naming the pitch, module size and quantity for each quoted glass area.
• Ask whether mullion trimming, custom modules or edge profiles are included; the EA250INV passage does not document them.
• Confirm the exact transparency within 70% to 90% for the selected pitch and configuration, and name the brightness, contrast, grayscale and refresh lines if content needs them.
• Separate cabling, mounting, control, spares, freight and commissioning into itemised lines.
• Match spare modules to every module size and pitch used in the quote.

Frequently asked questions

Does EA250INV film need to be cut around glass mullions?

The supplied EA250INV passage documents direct mounting on suitable indoor glass and lists 1,000 × 250 mm, 1,200 × 250 mm and 1,500 × 250 mm modules, but it does not document mullion trimming or cutouts. Ask the supplier to confirm in writing whether the quoted layout uses standard modules, trimmed film or a custom part at each mullion.

How should module quantities be quoted for a glass wall divided by mullions?

Ask the supplier whether the actual mullion layout requires module quantities to be quoted for each glass area rather than as one total. EA250INV module sizes are 1,000 × 250 mm, 1,200 × 250 mm and 1,500 × 250 mm, with combinations varying by pixel pitch, so the quotation must name the pitch and module size for every area it covers.

What dimensions should I give for an EA250INV quotation on a mullion-heavy glass wall?

Give the glass dimensions for each area, the mullion and frame positions and the door reveal details, plus the viewing distance, brightness requirements and content detail. The EA250INV source says module size and pixel pitch are selected according to viewing distance, glass dimensions, brightness requirements and content detail.

Does a door reveal change the cable routing line in an EA250INV quote?

The EA250INV passage does not set out a cable route or power location, so routing around a door reveal is a project question rather than a documented feature. Ask how power and data reach the film, whether any surface penetration is proposed, and whether trunking or protection is included, and keep the answer as a separate line.

Can one spare module cover every area in a mullion layout?

Ask for spares matched to each module size and pitch actually quoted. EA250INV documents three module sizes and three pitch options, with available combinations varying by pixel pitch, so a single generic spare should not be assumed to cover every quoted area.
