Why This Matters to You

Stretched/bar-format displays like this one are almost always produced by cutting down a standard-size mother panel rather than manufactured natively at the target size. For buyers integrating this into equipment (kiosks, signage, transportation displays, industrial control panels), the cutting process itself is the single biggest source of technical risk — and the biggest differentiator between suppliers. Below is a transparent breakdown of how we handle each stage, organized around the questions our OEM clients ask most often during technical due diligence.

1. Cutting Process & Feasibility

Cutting methodWe evaluate cutting method based on panel generation, cut-line location relative to the array, and target tolerance:

• Mechanical wheel cutting (scribe-and-break): used for straight cuts on non-critical edges, lower cost, standard for most bar-format conversions like this 32"→28.6" module.

• Ultrafast laser cutting: recommended when the cut line runs close to active circuit traces, when tighter edge tolerance is required, or when the customer's mechanical housing has very tight bezel clearance. Laser cutting reduces micro-chipping and heat-affected zone compared to mechanical scribing.

We confirm the appropriate method during DFM (Design for Manufacturability) review once we have your target dimensions.

Trace and array avoidanceEvery cut plan is checked against the source panel's Gate/Source driver layout and TFT array boundary before quotation. To confirm feasibility on a custom size, we typically request from you:

• Target active area (A.A.) dimensions and tolerance

• Preferred cut orientation (single-side cut vs. both-side symmetrical cut)

• Mechanical drawing or DXF of the housing/bezel opening

• Interface requirement (LVDS/HDMI/eDP) — this affects where the cut can be made relative to the driver IC and FPC

Our engineering team returns a feasibility report indicating whether the requested dimension falls inside a "safe cut zone" or requires bezel/AA compromise.

Edge quality standardPost-cut edges are inspected for flatness and micro-crack control under standard optical/visual inspection criteria before sealing. Edge chipping beyond internal tolerance is rejected at this stage — before sealing and lamination proceed — so defects are caught prior to added process cost.

2. Reliability & Edge Sealing

Sealing processEvery cut edge goes through a secondary sealing process — typically UV-cure edge dispensing — applied along the cut line to restore moisture and liquid-crystal containment that the original panel edge (factory-sealed) provided. This is the step that determines whether a cut panel survives field conditions rather than just passing initial QC.

Reliability testingThis panel is built to standard industrial-grade requirements (Operating Temp -20°C to 60°C). For custom-cut projects specifically, we can share reference test data from comparable cut-panel programs, including:

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

• Thermal shock / hot-cold cycling

• Structural drop testing (as applicable to the housing configuration)

If your project targets a specific certification level (consumer vs. industrial-grade duty cycle), tell us up front — test protocol and sample size are scoped to match.

Optical performance at the sealA poorly sealed or poorly cut edge typically shows up as light leakage along the border or a Mura band near the cut line. We inspect every sealed unit for this before shipment; if your application has a visible bezel margin (e.g., open-frame or bezel-less housing), let us know the visible AA tolerance so we can flag any risk during the feasibility stage rather than after tooling.

3. Cost, Yield & Lead Time

NRE & first sample costNon-recurring engineering cost for a custom cut/size project depends on: whether the cut plan requires laser vs. mechanical processing, FPC/driver board redesign, and tooling for a new bezel/backlight assembly. First-sample runs (~20 pcs) typically require 2–4 weeks from confirmed drawing approval; exact timing is quoted per project.

Standard vs. custom lead time

• Standard specification (as listed on this page): 2–3 weeks

• Custom cutting / brightness / bezel configuration: 4–6 weeks

Volume yield & MOQYield on cut-panel programs stabilizes once the cut plan, sealing parameters and inspection thresholds are locked from the sample run — we share expected yield range at quotation stage based on your specific cut geometry, since it varies with how close the cut line runs to the array edge. Standard-spec MOQ is 1 unit; custom cutting, brightness or bezel changes may adjust MOQ, which is confirmed at the time of quotation.
