86" Custom-Cut Stretched Bar LCD Display

For Retail Shelf-Edge, Digital Signage & Space-Constrained Installations

Technical & Commercial Brief for Overseas Engineers, Procurement Managers & Project Leaders

1. Product Overview

The 86" Stretched Bar LCD Display is engineered for ultra-wide, narrow-form applications where a standard 16:9 panel simply won't fit — shelf-edge advertising, transportation wayfinding, elevator/corridor signage, and menu boards. Rather than being manufactured as a native panel, this display is produced through precision cutting of a standard TFT-LCD mother panel, allowing us to deliver non-standard aspect ratios and lengths that match your exact mechanical enclosure — without the tooling cost of a new panel mold.

This makes it a preferred solution for OEM/ODM integrators and project teams who need a custom size, not just a catalog SKU.

Final specifications depend on the source mother-glass model and your target cut dimensions. We confirm exact optical and mechanical specs after DFM (Design for Manufacturability) review.

2. Why Customers Choose a Cut-to-Size Bar Display

• No new tooling / mold cost — reuse of a qualified mass-production panel keeps NRE low compared to a fully custom TFT design.

• Flexible aspect ratio — match the exact bezel opening of your kiosk, shelf, or vehicle interior.

• Proven base panel reliability — the source panel is already a qualified, mass-produced product; only the cut edge is a new process to validate.

• Faster time-to-sample than a new panel tape-out.

3. Technical Process & Feasibility (What We Evaluate Before Quoting)

We treat every custom-cut project as a formal DFM exercise. Below is what we assess, and what we need from you, before confirming feasibility.

3.1 Cutting Method

We select between mechanical wheel scribing and ultrafast laser cutting based on:

• Target dimensional tolerance (tighter tolerances and complex/irregular edges favor laser)

• Cut-line proximity to active display area

• Glass thickness and panel generation

We will recommend the appropriate method once we see your target outline drawing.

3.2 Circuit & Trace Clearance

Before confirming any cut line, we run a layout check against the panel's Gate/Source driving lines and TFT array boundary to confirm the new cut edge does not intersect active circuitry or bonding pad routing.

To begin feasibility review, please provide:

• Target outline dimensions and tolerance (±mm)

• 2D/3D mechanical drawing of the intended cut area (DXF/STEP/PDF)

• Preferred cut edge reference point(s) relative to the active area

• Any keep-out zones required by your enclosure design

3.3 Edge Quality Standard

Post-cut glass edges are inspected against defined criteria for edge flatness (flush/chamfer profile) and micro-crack control, verified under microscope sampling per lot. Specific acceptance criteria (e.g., max chip size, crack propagation limit) are shared in the quality agreement per project.

4. Reliability & Edge-Sealing Assurance

Cutting a panel creates a new glass edge that must be protected against moisture ingress and liquid crystal leakage. Our standard process includes:

• Secondary sealing process: UV-cure edge dispensing (dam-and-fill) applied along the cut edge to restore moisture/LC-leak protection — alternative sealant systems available depending on panel type and customer reliability targets.

• Reliability qualification: Cut modules are put through standard consumer-grade or industrial-grade test protocols (to be aligned with your application), including:

  Benchmark data from comparable past cutting projects is available under NDA upon request — please advise your target reliability grade (consumer / industrial) so we can share the most relevant dataset.

• Double-85 (85°C/85%RH) high-temperature high-humidity soak

• High/low temperature cycling (thermal shock)

• Structural drop testing

• Optical performance at the edge: Sealed edges are inspected for light leakage and color shift (Mura) in the border region; edge dispensing width and cure profile are tuned specifically to minimize both.

5. Cost, Yield & Lead Time

*Exact figures depend on panel generation, cut complexity, and target reliability grade. We provide a firm quotation after reviewing your mechanical drawing and target specification.

6. Applications

• Retail shelf-edge price/promotion displays

• Elevator, corridor & transportation wayfinding signage

• Menu boards and space-constrained digital signage

• Kiosk and vending integration where enclosure geometry is fixed

7. Engineering Support Process

1. Submit your target outline drawing, dimensional tolerance, and reliability grade requirement.

2. DFM Review — we assess cut method, circuit clearance, and confirm technical feasibility.

3. Quotation — NRE, sample lead time, and indicative unit pricing.

4. Sampling — first article production and reliability test report.

5. Mass Production — yield data, MOQ, and delivery schedule confirmed.
