Custom-Cut Stretched LCD Solutions

Technical & Commercial Capability Brief — For OEM Engineers, Procurement Managers & Project Leads

Reference product: 37.6" Custom Stretched LCD for Industrial Machines — Model SG3763S01‑1Manufacturer: Shenzhen Hantu Jiashi Technology Co., Ltd. (HITULCD) — est. 2014, Shenzhen, China

1. Product Snapshot

This module is representative of our custom stretched-bar cutting platform — the same engineering process applies to other panel generations and aspect ratios (ultra-wide bar displays for kiosks, gas pumps, elevators, vending, and industrial control panels).

2. Technical Process & Feasibility

How we evaluate a custom cutting request

Every custom bar-display project starts with a joint feasibility review before any cutting is scheduled. To assess feasibility accurately, our engineering team typically requests:

• Target outline dimensions and tolerance requirements

• Original panel model / datasheet (if a standard panel is being re-cut)

• Mounting/bezel drawing or mechanical interface drawing (DXF/DWG preferred)

• Required viewing area (A.A.) and any keep-out zones

Cutting method

We select between mechanical wheel scribing and ultra-fast laser cutting based on glass thickness, target tolerance, and edge-quality requirements:

• Mechanical wheel cutting — cost-efficient for standard tolerances (±0.3–0.5 mm typ.), suited to straight-line cuts on thin substrate glass such as this 0.5+0.5 mm cell.

• Ultra-fast laser cutting — used when tighter tolerance (±0.1 mm or better), irregular contours, or minimal micro-crack propagation is required. This is our recommended method for panels intended for sealed/outdoor or vibration-prone applications.

The final recommendation is confirmed per project after reviewing the target dimensions against the panel's active array layout.

Circuit & routing clearance

Before confirming a cut line, we run a layout check against the Gate/Source driving lines and TFT array boundary to ensure the new cut edge does not intersect active circuitry or COF bonding pads. Where a requested dimension would cut into the array or driver routing, we will flag this during the DFM (Design-for-Manufacture) review and propose the nearest feasible alternative dimension, or a driver IC re-routing option for larger custom orders.

Edge quality control

Post-cut glass edges are inspected against internal QC limits for:

• Edge chipping / flatness (visual + magnified inspection)

• Micro-crack length and depth

• Edge squareness relative to the display's active area

Panels outside tolerance are rejected before sealing, so no defective edges advance to the next process step.

3. Reliability & Edge-Sealing Assurance

Sealing process

After cutting, exposed glass edges are re-sealed using UV-cure edge dispensing (glue dotting/dispensing) to restore moisture and liquid-crystal leakage protection at the cut line. Dispensing parameters (bead width, cure time, UV intensity) are adjusted per glass thickness and cut geometry to ensure full edge coverage without intruding into the active area.

Reliability testing

Cut-and-sealed modules can be qualified against standard consumer-grade or industrial-grade reliability protocols, depending on the target application. Typical test batteries include:

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

• High/low temperature storage & operating cycling

• Thermal shock (cold-hot cycling)

• Structural drop test (per packaging/mounting configuration)

Test benchmarks and pass/fail criteria are shared per project on request, referencing prior cutting programs of similar glass thickness and cut length — please specify your target industry standard (e.g., IEC, MIL-STD, or an internal OEM spec) so we can align the test plan and provide relevant historical data.

Optical performance after sealing

A properly sealed cut edge should show no visible light leakage or Mura (color shift/non-uniformity) at the border under normal viewing conditions. This is verified during final optical inspection under darkroom lighting before the module ships. Any samples showing edge Mura are re-worked or scrapped rather than shipped.

4. Cost, Yield & Lead Time

NRE & first-sample cost

Custom cutting programs carry a one-time NRE (Non-Recurring Engineering) fee covering tooling/fixture setup, DFM review, and initial cutting-parameter qualification. The exact NRE amount depends on the source panel, target dimension, and cutting method (mechanical vs. laser), and is quoted after the feasibility review.

• First sample (proto) run: typically 20 pcs

• Standard sample lead time: 2–3 weeks for stock/near-standard configurations; 4–6 weeks for fully custom cutting + sealing programs, consistent with our published lead times.

Volume production expectations

• Expected yield for qualified custom-cut programs is generally in line with standard LCM production once the cutting/sealing process is validated at sample stage; exact yield is confirmed after the first pilot batch, as it depends on cut length, glass thickness, and tolerance class.

• MOQ: Standard-spec modules start at MOQ 1 unit for evaluation; custom brightness, cutting, or bezel configurations typically require a higher MOQ, confirmed at the time of quotation.

• Monthly capacity: 12,000+ units/month across our production lines, supporting prototype, small-batch, and volume programs.

5. Why Source Custom-Cut Displays From HITULCD

• Documented compliance — CE / FCC / RoHS as standard; UL / CCC / EAC available on request; RoHS & REACH documentation available for ESG due diligence

• 12-month product warranty with continued engineering support post-shipment

• Transparent commercial terms — EXW / FOB / CIF shipping, T/T, L/C, PayPal (buyer-protected for samples), and O/A terms for long-term partners

• Verifiable business entity — Shenzhen Hantu Jiashi Technology Co., Ltd., Unified Social Credit Code 91440300306068446B, active registration since 2014

6. Next Steps

To begin a feasibility review for your custom-cut bar display, please share:

1. Target outline dimensions & tolerance

2. Source panel model (if re-cutting an existing panel) or target resolution/brightness

3. Mechanical/mounting drawing (DXF/DWG)

4. Target reliability standard (industrial / consumer-grade) and operating environment

5. Estimated annual volume, for MOQ and pricing alignment
