48.5" Custom Bar LCD for Commercial Display Systems

Ultra-Wide Cut-to-Size TFT Display | Engineered for OEM Integration

Overview

The 48.5" Custom Bar LCD is a precision-cut, stretched-format TFT panel designed for applications where a standard 16:9 display cannot fit — transportation information boards, retail shelf-edge signage, elevator displays, drive-thru menu boards, and industrial control panels. It is manufactured by re-cutting a large-format mother glass panel (typically 55") to the required ultra-wide aspect ratio, then re-sealing and re-testing the module to full commercial-grade reliability standards.

This datasheet is written for engineers, sourcing/procurement managers, and project owners evaluating a custom-cut bar display for a new program — covering not just specifications, but the engineering process, reliability data, and commercial terms typically required to move from RFQ to production.

Key Specifications

Exact resolution, active area, and mechanical drawing are confirmed jointly during the DFM (Design for Manufacturability) stage based on your target cut dimensions.

1. Cutting Process & Engineering Feasibility

Q: What cutting method do you recommend, and how are dimensional tolerances controlled?Two cutting methods are available depending on volume and precision requirements:

• Mechanical wheel scribing — cost-effective for standard rectangular cuts, suitable for most signage applications.

• Ultrafast laser cutting — recommended for tighter tolerances, irregular cut lines, or when the cut line falls close to active circuitry, as it minimizes micro-cracking and edge stress.

Our engineering team recommends the cutting method after reviewing your target dimensions and tolerance requirements during the feasibility review.

Q: Will the cut line interfere with the Gate/Source traces or the TFT array?This is the first item checked in feasibility review. Before confirming a cut plan, we require:

• The exact target cut dimensions (width × height) and cut-line position relative to the panel's active area

• The base panel's Gate/Source driving direction and IC/COF bonding location (from the mother panel's datasheet, or we can supply this if we source the mother glass)

• Any required keep-out zones for your housing/bezel design

This allows us to confirm whether the cut line clears the circuit region, or whether re-routing/COF relocation is needed — before any glass is cut.

Q: What is your standard for edge flatness and micro-crack control after cutting?Cut edges are inspected under microscope for edge chipping and micro-crack propagation against an internal AQL standard, with edge grinding/polishing applied where required by the application (e.g., touch-enabled or exposed-edge designs).

2. Reliability & Edge Sealing

Q: How do you seal the cut edge against moisture and liquid crystal leakage?Cut edges are re-sealed using a secondary UV dispensing/curing process along the exposed glass edge, forming a moisture and LC-leakage barrier. Sealant type and dispensing pattern are adjusted based on panel structure (open-cell vs. with cover lens) and the target environment (indoor vs. semi-outdoor/washdown).

Q: Can the cut module pass standard reliability testing? What benchmark data can you share?Yes — cut/re-sealed modules go through the same qualification battery as standard modules, selected per application grade (consumer / industrial):

• Double 85 (85°C / 85% RH) test — typically run 96–240 hrs depending on grade

• High/low temperature cycling — per your operating temp. spec, multiple cycles

• Thermal shock

• Structural drop test — for housed/portable applications

We can share test reports/benchmark data from comparable prior cutting projects (similar size and sealing method) under NDA during the qualification stage.

Q: Does the sealed edge cause light leakage or color shift (Mura) near the border?Edge-adjacent Mura risk is managed through backlight design (LED placement relative to the new cut edge) and sealant thickness control. We perform 100% optical inspection on cut units for edge-region light leakage and color uniformity before shipment; any unit outside spec is rejected at this stage.

3. Cost, Yield & Lead Time

Q: What is the typical NRE cost, and how long does a first sample run (e.g. 20 pcs) take?NRE for a new custom cut (tooling/fixture, cutting program setup, DFM validation) is quoted per project based on cut complexity and required tolerance — please share your target drawing for a firm quote. First-sample lead time is typically 2–4 weeks from drawing confirmation, depending on cutting method and mother-glass availability.

Q: What yield should we expect at mass production, and what is your MOQ?Mass-production yield for a validated cut design (post-DFM, tooling locked) typically stabilizes in a healthy commercial range once the process is qualified; exact figures depend on cut complexity and are shared transparently after the pilot run. MOQ for production orders is set per project scale — smaller MOQs are achievable when the cut dimension matches an already-qualified process.

Applications

• Public transportation displays (bus, rail, airport signage)

• Retail shelf-edge and digital signage

• Elevator and lobby information displays

• Drive-thru and QSR menu boards

• Industrial control panels and HMI

Compliance & Quality

All panels are engineered to meet CE, FCC, and RoHS requirements for EU and North American deployment, and are free of restricted hazardous substances (lead, mercury, cadmium, hexavalent chromium). Full-spectrum burn-in and 100% pixel/optical inspection are standard prior to shipment.

Next Steps for Your Project

To begin feasibility review, please share:

1. Target cut dimensions and tolerance requirements

2. Mother panel source/datasheet (if specified) or your resolution/brightness requirement

3. Operating environment (indoor / semi-outdoor / outdoor) and any IP or certification requirements

4. Target volume and program timeline

Our engineering team will return a DFM feasibility assessment, NRE quote, and sample lead time within 2–3 business days of receiving your drawing.
