Quick answer
For an indoor curved feature, start with the substrate. EA250INV is an indoor invisible LED film for glass walls and storefronts, with up to 90% transparency, 2 mm modules about 1.3–1.5 kg, P3.91, P6.25 or P10.42, and direct mounting on suitable glass. EA-Flex is an indoor soft flexible display for curved, cylindrical, wavy and irregular shapes, with magnetic front service and a stated ≤45° bending limit. Confirm the exact substrate, geometry and support structure.

Start with substrate and shape
The choice between EA250INV and EA-Flex is not a simple film-versus-panel preference. EA250INV is documented as an indoor invisible LED film display for glass walls and storefronts, with direct mounting on suitable indoor glass surfaces and no conventional steel support frame. EA-Flex is documented as an indoor flexible LED display built from soft, bendable modules for curved LED walls, cylindrical displays, wavy screens, spherical displays and irregular-shaped signs, using magnetic assembly on a suitable metal support structure. If the feature is glass, EA250INV enters first; if the feature is a shaped surface, EA-Flex enters first. For an irregular indoor feature, start with the surface geometry rather than the product label.
A curved glass feature is a separate question from a transparent glass wall. The EA250INV evidence covers glass walls and storefronts and direct glass mounting; confirm whether the exact configuration is approved for the proposed curve or shape. EA-Flex states a bending limit of ≤45° and describes curved, cylindrical, wavy, spherical and irregular shapes. If the design is curved, do not treat film as automatically bendable. For a curved glass transparent LED film concept, ask for written confirmation of the exact geometry before comparing totals.
EA250INV: glass-mounted invisible film
EA250INV documents up to 90% transparency, but the finer figure is 70% to 90% depending on pixel pitch and configuration. Modules are 2 mm thick and weigh approximately 1.3–1.5 kg depending on module size. The three module sizes are 1000 × 250 mm, 1200 × 250 mm and 1500 × 250 mm, with available combinations varying by pixel pitch. The model supports P3.91, P6.25 and P10.42, with pixel densities from 9,216 to 65,536 pixels/m². Use the pitch and transparency selection as one linked decision, not two independent choices.
Brightness is documented from 1,500 to 4,500 cd/m², contrast up to 9,000:1, 16-bit grayscale, refresh at least 3,840 Hz and a 140° viewing angle. Ask for those values to be stated for the quoted pitch and module mix. Direct mounting is on suitable indoor glass surfaces without a conventional steel support frame. Applications named include retail windows, shopping malls, exhibition halls, museums, showrooms and creative commercial displays.

EA-Flex: soft modules for shaped surfaces
EA-Flex is an indoor flexible LED display built from soft, bendable LED modules. The source describes curved LED walls, cylindrical displays, wavy screens, spherical displays and irregular-shaped signs. The stated bending limit is ≤45°. It uses magnetic assembly and front service: modules attach to a suitable metal support structure, and technicians can remove and service modules from the front using dedicated tools. The support structure should match the intended screen shape.
EA-Flex documents five module sizes: 240 × 120 mm, 320 × 160 mm, 256 × 128 mm, 250 × 250 mm and 300 × 168.75 mm. Brightness is 600–800 cd/m² depending on the model, viewing angle is 140° and refresh is ≥3,840 Hz. The source describes custom-shaped indoor screens for curved walls and irregular architectural surfaces and asks for screen dimensions, intended shape and viewing distance to discuss a suitable configuration.
Transparency, brightness and substrate tradeoffs
The clearest documented difference is transparency versus shape. EA250INV documents transparency up to 90%, with 70% to 90% by pixel pitch and configuration, so it is the glass-film route when preserving daylight and sightlines matters. EA-Flex evidence focuses on soft, bendable modules for curved and irregular shapes. If the design requires both high transparency and a curved surface, ask for written geometry approval and do not assume one family covers both.
EA250INV configurations provide 1,500 to 4,500 cd/m², while EA-Flex lists 600–800 cd/m² depending on model. Treat those as documented ranges rather than a ranking. The supplied evidence does not establish a brightness-to-ambient-light suitability rule for either model, so request the operating brightness preset and a content test at the intended indoor light level. For acceptance, keep the quoted LED wall brightness as a configuration line for the exact model and pitch.
Service, support structure and control
EA250INV mounts directly to suitable indoor glass surfaces and does not require a conventional steel support frame. That means the glass substrate, mounting method and service access must be confirmed for the exact build. Ask how modules, power and data are reached after installation and what spare module is recommended for the ordered pitch and module size.
EA-Flex uses magnetic assembly on a suitable metal support structure, with front service using dedicated tools. The source says the support structure should match the intended screen shape. For a curved feature, the metal support structure is therefore part of the display scope, not an optional extra. Ask for the support interface, module map and service clearance in the installed orientation.
Decision sequence and when to defer
First, classify the surface: glass wall, storefront, curved glass, cylindrical column, wavy wall, sphere or irregular sign. Second, decide whether transparency is a primary requirement. If yes, compare EA250INV’s documented 70% to 90% transparency by pitch and configuration. If the shape is the primary requirement, compare EA-Flex’s soft modules and ≤45° bending limit. Third, check substrate: direct glass mounting for EA250INV versus a suitable metal support structure for EA-Flex.
Defer the final choice when the exact glass surface, curve or shape, support structure, viewing distance or service route is unresolved. EA250INV combinations vary by pixel pitch, and EA-Flex requires confirmation of the shape against the ≤45° limit. A quotation built on different assumptions is hard to compare. Keep module size, pitch, transparency, brightness, support, control, delivery and spares as separate lines so you can compare LED screen quotes on the same scope.
Scenario choices for an indoor curved feature
| Scenario | What to confirm |
|---|---|
| Curved glass storefront where transparency matters | Confirm whether the exact EA250INV configuration is approved for the curve, and request the transparency figure within the 70%–90% range for the selected pitch and configuration. |
| Cylindrical, wavy or irregular indoor feature | EA-Flex documents curved, cylindrical, wavy, spherical and irregular shapes; confirm the proposed shape against the ≤45° bending limit, module configuration and metal support structure. |
| Glass wall with no conventional frame | EA250INV mounts directly to suitable indoor glass without a conventional steel support frame; confirm glass suitability, mounting scope and service route. |
| High indoor brightness | Compare EA250INV 1,500–4,500 cd/m² with EA-Flex 600–800 cd/m² depending on model, and request an operating brightness preset for the actual room. |
| Service access is uncertain | EA-Flex documents magnetic front service with dedicated tools; for EA250INV, ask how modules, power and data are reached and what spare module is recommended. |
| Both transparency and a curved shape are required | Ask for written geometry approval for the exact configuration; do not assume one product family covers both without supplier confirmation. |
Buyer checklist
- Name the substrate and shape first: glass wall, storefront, curved glass, cylindrical, wavy, sphere or irregular sign.

- For EA-Flex, confirm the proposed shape against the ≤45° bending limit and the module configuration.
- Confirm the mounting substrate: direct glass mounting for EA250INV, or a suitable metal support structure for EA-Flex.
- Request a module map with exact size, pitch and quantity for the quoted build.
- Keep support structure, control, delivery and spare modules as separate quotation lines.
Frequently asked questions
Can EA250INV be used on a curved indoor glass feature?
The reviewed EA250INV passages describe glass walls and storefronts and direct mounting on suitable indoor glass, but they do not set out a bending limit or curved-shape capability. Ask for written confirmation that the exact EA250INV configuration is approved for the proposed curve. If the curve is the primary requirement, EA-Flex documents a ≤45° bending limit and curved, cylindrical, wavy, spherical and irregular shapes.
Is EA-Flex a transparent LED film for glass?
EA-Flex is documented as an indoor flexible LED display built from soft, bendable modules for curved, cylindrical, wavy, spherical and irregular-shaped screens. The reviewed passages do not present it as a transparent glass-mounted film. EA250INV is the documented glass-film route, with up to 90% transparency and 70%–90% by pixel pitch and configuration. Choose by whether transparency or shape drives the brief.
Which model has the higher documented brightness?
EA250INV configurations provide 1,500 to 4,500 cd/m². EA-Flex lists 600–800 cd/m² depending on model. A higher listed range is not an automatic selection rule; request an operating brightness preset and content test at the actual indoor light level.
How do mounting and service methods differ?
EA250INV mounts directly to suitable indoor glass surfaces without a conventional steel support frame. EA-Flex uses magnetic assembly on a suitable metal support structure, with front service using dedicated tools. Ask how modules, power and data are reached for the exact configuration.
What should be confirmed before ordering?
Confirm substrate, shape, module size, pixel pitch, transparency, brightness, support structure and service route. EA250INV combinations vary by pixel pitch, and EA-Flex requires confirmation against the ≤45° bending limit. Keep these as separate quotation lines rather than comparing a single total.
