28.6" Stretched LCD Panel (P286IVN01.0) — Technical & Engineering Brief

For OEM Integrators, Procurement Managers & Project Engineers

1. Product Overview

The P286IVN01.0 is a 28.6" ultra-wide stretched-bar LCD module, produced by cutting a standard 32" a-Si TFT-LCD panel in half ("32" 1/2 Cut Panel"). This gives OEMs a cost-effective, high-availability bar-format display without waiting on a dedicated bar-panel production line.

This brief addresses the technical due-diligence questions that engineering and procurement teams typically raise before committing to a custom-cut bar panel project.

2. Cutting Process & Design Feasibility

2.1 Cutting method

We evaluate cutting method on a per-project basis according to target size and tolerance:

• Mechanical wheel scribing (cut & break) — suitable for straightforward rectangular cuts with standard tolerance requirements; lower cost, shorter lead time.

• Ultrafast laser cutting (cold cutting) — recommended when tighter dimensional tolerance, minimal micro-crack risk, or a cut line close to active circuitry is required. Laser cutting produces a cleaner edge with reduced heat-affected zone (HAZ), at a higher unit cost.

The recommendation is confirmed during the DFM (Design for Manufacturability) review once your target dimensions and tolerance class are provided.

2.2 Circuit clearance & routing check

Before any cut line is finalized, our engineering team cross-checks the proposed cut against the source panel's Gate/Source driving IC layout and TFT array boundary to confirm:

• No interference with active Gate/Source trace routing

• Sufficient clearance margin from the array edge to avoid leakage current or dead-line defects

• Compatibility with the existing LVDS/COF (Chip-on-Film) bonding position, or whether COF relocation/re-bonding is required

Information required from you to begin feasibility review:

1. Target final dimensions (W × H) and tolerance requirement (±mm)

2. Mounting/bezel drawing or mechanical interface drawing (DXF/DWG/STEP preferred)

3. Required active display area (if cropped from original AA)

4. Interface requirement (LVDS pin-out reused, or new COF/PCBA needed)

5. Intended orientation and viewing direction

Our team will return a cut-line proposal marked against the original panel's array map, along with a feasibility confirmation (Go / Go-with-conditions / No-go) within the initial review.

2.3 Edge quality standard

Post-cut edges are inspected against internal QC criteria covering:

• Edge straightness/flatness: controlled within our standard tolerance band per cut length (confirmed at quotation stage based on final size)

• Micro-crack / chipping control: 100% visual + magnified inspection; edges exceeding chip depth or crack-propagation limits are rejected

• Edge grinding: chamfered/ground edge finish available on request to reduce stress concentration points

3. Sealing & Reliability Assurance

3.1 Secondary sealing process

After cutting, the exposed cell edge (where liquid crystal material and polarizer layers are exposed) is treated with a secondary sealing process to restore moisture/liquid-crystal containment:

• UV-cure edge sealant (dispensed) is our standard method — applied along the cut edge and cured under UV to form a moisture barrier

• Edge sealing is validated with dye-penetration / visual leak-check before the module proceeds to burn-in

3.2 Reliability test data

Cut-panel modules are qualified against the same reliability program used for our standard modules, tier selectable per your end-application (consumer-grade vs. industrial-grade):

We can share sample test reports/data from comparable prior cut-panel programs under NDA during the qualification stage — exact pass/fail benchmarks depend on the final mechanical design (bezel, backing plate, mounting stress) and will be re-verified for your specific configuration rather than assumed from a different project.

3.3 Optical performance after edge sealing

Known risk areas after cutting/sealing are actively controlled for:

• Light leakage at the cut edge — mitigated via backlight light-guide masking/trimming plus the edge seal itself; inspected under dark-room conditions

• Mura / color shift near the cut boundary — checked against our standard Mura acceptance criteria (uniformity photometric scan); any panel showing localized non-uniformity beyond spec is screened out before shipment

4. Cost, Yield & Lead Time

* Final figures are confirmed once your drawing, tolerance class, and volume forecast are reviewed — we do not want to quote a number that doesn't reflect your actual cut-line complexity.

5. Compliance & Supplier Verification

• Certifications: CE / FCC / RoHS standard; UL / CCC / EAC available on request; ISO9001, REACH, WEEE

6. Next Step

To move to a formal feasibility review and quotation, please share:

1. Target dimension & tolerance drawing

2. Mechanical/mounting interface drawing

3. Interface requirement (reuse existing LVDS pinout or new design)

4. Target application environment (indoor/outdoor, temperature range, expected test standard — consumer or industrial)

5. Estimated annual volume

Our engineering team will return a cut-line feasibility assessment, sealing process recommendation, and formal NRE/sample quotation.
