48.5" Stretched Bar TFT LCD for Transit Display Systems

Custom-Cut Ultra-Wide Panel | 1920×360 | High-Brightness | OEM/ODM

1. Product Overview

The 48.5" Stretched Bar TFT LCD is an ultra-wide, high-brightness display panel engineered for public transportation applications — bus and rail arrival boards, in-vehicle passenger information displays (PIDs), platform screens, airport gate strips, and digital wayfinding signage. Its elongated 48:9-class aspect ratio (1920×360) fits narrow architectural and vehicle-mounted recesses where a standard 16:9 panel cannot be installed, while preserving full HD-equivalent horizontal resolution for text and route information.

This panel is available as a cuttable/resizable base model, allowing us to trim the glass on one axis to match a customer's exact enclosure dimensions — a common requirement for transit operators replacing legacy displays or standardizing on non-catalog form factors.

2. Why Transit Integrators Choose This Panel

• Fits where standard panels can't — purpose-built for bus interiors, rail platform recesses, elevator door headers, and station signage channels.

• Sunlight-readable performance — 1,000-nit baseline covers covered platforms and shop-window-level ambient light; higher-brightness direct-lit variants are available for uncovered, direct-sun installations.

• Engineered for continuous duty — rated for 24/7 operation without thermal throttling, matching the uptime requirements of public transit infrastructure.

• OEM-ready customization — cuttable on one axis to match your exact chassis or enclosure dimensions; custom aspect ratios are available for OEM orders of 50+ units.

3. Technical Feasibility & Custom-Cutting Process

We understand that engineering teams evaluating a custom-cut panel need clear answers before committing to a design. Below is how we approach the technical questions our overseas partners most commonly raise during the RFQ stage.

3.1 Cutting Method & Tolerance

• Two cutting technologies are available depending on target dimension, tolerance, and edge-quality requirements:

• Mechanical wheel (scribe-and-break) cutting — cost-effective for straightforward, larger-tolerance cuts.

• Ultra-fast laser cutting — recommended for tight-tolerance cuts, thinner glass, or cut lines close to the active display area, as it produces a cleaner edge with reduced micro-crack risk.

• Final tolerance and recommended method are confirmed after reviewing the customer's target outline dimensions and mechanical drawing.

3.2 Trace & Circuit Clearance Review

• Before confirming feasibility, our engineering team checks whether the proposed cut line intersects the panel's Gate/Source driving lines or the active TFT array area.

• To complete this review, please provide:

• Target cut dimensions (with tolerance) and desired active area, ideally as a dimensioned drawing (DWG/DXF/PDF acceptable)

• Mounting/bezel constraints and viewing-area requirements

• Interface requirements (LVDS/VGA/HDMI) and connector orientation, if cutting near the FPC/driver side

• Based on this input, we return a feasibility confirmation indicating whether the cut is achievable without impacting active pixels, and where the practical cut-line boundary sits.

3.3 Edge Quality Standard

• Post-cut edges are inspected against defined flatness and chip/micro-crack tolerance limits before proceeding to sealing.

• Edges falling outside spec at inspection are rejected prior to the sealing stage, protecting downstream reliability performance.

4. Sealing Process & Reliability Assurance

4.1 Edge Sealing (Anti-Leakage / Moisture Protection)

• Cut edges undergo a secondary sealing process to protect against liquid-crystal leakage and moisture ingress — typically UV-cure dispensed sealant applied along the cut edge, with process parameters adjusted to panel thickness and cut-edge geometry. Alternative sealing methods can be discussed for specific customer reliability targets.

4.2 Reliability Testing

• Cut-and-sealed modules can be qualified against consumer-grade or industrial-grade reliability protocols, depending on the target deployment environment. Typical benchmark testing includes:

• 85°C/85% RH (double-85) high-temperature, high-humidity soak testing

• High/low temperature cycling (thermal shock)

• Structural drop testing

• Test reports and benchmark data from comparable cut-panel projects are available for review under NDA upon request — please let us know your target test standard (e.g., IEC/EN transit or industrial display standards) so we can match reference data accordingly.

4.3 Optical Performance After Cutting/Sealing

• Cut-and-sealed edge zones are inspected for light leakage and color shift (Mura) as part of final optical QC, to confirm the sealing process has not introduced visible non-uniformity at the panel border.

5. Cost, Yield & Lead Time

Exact NRE, sample lead time, yield benchmark, and MOQ figures are confirmed once we receive your target dimensions, tolerance, and drawing — we're happy to provide a written quotation and project timeline against your specification.

6. Applications

• Bus & rail arrival/departure information displays

• In-vehicle passenger information displays (PIDs)

• Platform and station wayfinding signage

• Elevator door header displays

• Airport gate and concourse status strips

• Retail shelf-edge and drive-through menu boards (shared platform, non-transit use)

7. Next Steps for Your Project

To move your project from inquiry to feasibility confirmation, please share:

1. Target outline dimensions and active area (drawing preferred: DWG/DXF/PDF)

2. Required tolerance and mounting/enclosure constraints

3. Brightness and operating environment (indoor / covered outdoor / direct-sun outdoor)

4. Target reliability standard and sample quantity for first article

5. Expected annual volume, for MOQ and pricing guidance

Our engineering team will return a feasibility assessment, recommended cutting method, and project timeline based on your specification.
