DV480FBM-N01 — 48" Native Stretched Bar LCD Module for Transportation & Digital Signage Integration

Manufacturer: HITULCD (Shenzhen Hantu Jiashi Technology Co., Ltd.)Category: Stretched Bar Display / Ultra-wide LCD ModuleTarget Applications: Bus/rail passenger information displays, transportation signage, industrial digital signage, retail bar displays

1. Product Overview

The DV480FBM-N01 is a 48-inch native stretched bar TFT-LCD module (5.33:1 aspect ratio, 3840×720) engineered for ultra-wide, high-brightness information displays in transportation and public digital signage environments. Unlike cut-to-size panels, this is a factory-native bar panel, which eliminates the edge-sealing and reliability risks associated with post-production glass cutting — a key consideration for buyers sourcing for rolling stock, buses, and outdoor/semi-outdoor kiosks.

This module is supplied as part of HITULCD's direct in-house manufacturing program, giving OEMs, system integrators, and distributors direct engineering access for customization, OEM/ODM development, and volume production.

2. Key Specifications

⚠️ Engineering Note: This panel uses a V-by-One 8-lane interface and requires a dedicated V-by-One driver/control board. A standard LVDS controller cannot drive this panel directly — please confirm control board compatibility during system design.

3. Why This Module Fits Transportation & Signage Projects

• Ultra-wide native format — purpose-built 5.33:1 bar shape avoids the compromises of cutting a standard panel down to size, giving consistent optical performance edge-to-edge.

• 1000-nit brightness — legible under strong ambient light common in bus/rail cabins and window-facing installations.

• Wide operating temperature range (0–50°C) and industrial-grade backlight rated for 24/7 duty cycles typical of public transit signage.

• Hard-coated, low-haze surface (3H, 1% haze) for durability against cleaning and incidental contact in high-traffic public environments.

• Certified for export: ISO9001, CE, RoHS, FCC, REACH, WEEE as standard; UL / CCC / EAC available on request for region-specific compliance (EU, US, Eurasian markets).

4. Engineering & Customization FAQ

The following addresses the technical due-diligence questions our overseas engineering and procurement partners typically raise before issuing a PO. Where a figure is project- or spec-dependent, we confirm it in writing at the RFQ/DFM (Design for Manufacture) stage.

4.1 Cutting & Custom Sizing (for projects requiring non-standard cut panels)

• Cutting method: For custom-cut bar displays, HITULCD selects between mechanical wheel scribing and ultrafast laser cutting depending on glass thickness, target tolerance, and edge-quality requirements. Laser cutting is generally recommended for tighter tolerances and reduced micro-crack risk.

• Circuit clearance: All proposed cut lines are cross-checked against the Gate/Source trace layout and active TFT array before confirming feasibility, to avoid signal-line interference.

• Documents needed for feasibility review: Target outline dimensions, mounting/cutout drawing (DXF/DWG preferred), panel orientation requirements, and any bezel or mounting constraints.

• Edge quality standard: Post-cut edge flatness and micro-crack tolerance are controlled to internal QC limits and verified under microscope inspection prior to sealing.

Note: The DV480FBM-N01 itself is supplied as a native (non-cut) stretched bar panel, which avoids these cutting-related risks entirely — recommended where the standard 5.33:1 format fits the application.

4.2 Edge Sealing & Reliability (for cut-panel projects)

• Sealing process: Cut edges are re-sealed using UV-cure dispensed sealant to restore moisture and liquid-crystal leakage protection at the cut line.

• Reliability testing: Cut modules are evaluated against standard reliability protocols — including double 85 (85°C/85% RH) high-temperature/humidity testing, thermal shock cycling, and structural drop testing. Test reports for comparable past cutting projects can be shared under NDA on request.

• Optical performance at the seal line: Edge regions are inspected for light leakage and color-shift (Mura) after sealing; panels outside acceptable Mura thresholds are rejected before shipment.

4.3 Cost, Yield & Lead Time

• NRE / tooling cost: Custom cutting or bezel programs carry a one-time NRE fee, quoted per project based on size, tolerance, and tooling requirements.

• Sample lead time: Standard product samples ship in stock or within the standard 2–3 week lead time; custom-cut or custom-spec samples typically require 4–6 weeks, confirmed at quotation.

• Mass production yield & MOQ: Standard native-panel products carry a MOQ of 1 unit. Custom cutting, brightness, or bezel modifications may raise the MOQ — this is confirmed at the quotation stage along with expected production yield for the specific configuration.
