28.6" Custom TFT LCD Module (1/2-Cut from 32" Panel) — Technical & Sourcing Brief

Model: P286IVN01.1 | Stretched Bar Display | OEM/ODM

Why This Product Exists

Standard 32" TFT panels are not naturally ultra-wide. To achieve the 3.56:1 bar-type aspect ratio increasingly requested for digital signage, self-checkout toppers, vending machines, ATMs, and embedded industrial HMIs, HITULCD precision-cuts a standard 32" a-Si TFT-LCD panel down to a 28.6" active display area (698.4×196.425 mm A.A.), then re-seals and re-qualifies it as a production-grade module.

This document is written for sourcing engineers, project managers, and technical buyers evaluating cut-panel bar displays, and answers the questions we are asked most often before an RFQ is issued.

1. Cutting Process & Design Feasibility

Cutting methodWe select the cutting method based on your tolerance requirements and glass thickness, not by default:

Circuit and trace clearanceBefore any cut is approved, our engineering team maps the Gate/Source driver IC placement and TFT array boundary of the source panel against your requested cut line. This determines:

• Which side of the panel can be cut without severing active gate/source lines

• Whether the driver board / COF needs to be relocated or re-flexed

• The minimum safe margin between the new glass edge and the last active pixel row

What we need from you at the feasibility stage

• Target outline dimensions (W × H) and tolerance class

• Mounting/bezel drawing (DXF/STEP preferred) if the module integrates into an existing enclosure

• Interface preference (LVDS pass-through vs. HDMI/VGA control board)

• Any keep-out zones for existing mechanical fasteners or connectors

We return a cut-feasibility confirmation (with recommended method and edge margin) before quoting, so there are no surprises after tooling starts.

Edge finishingPost-cut edges are ground and polished to remove micro-cracks and sharp chipping. Edge flatness and micro-crack density are inspected under magnification against an internal AQL standard before a panel proceeds to sealing — panels outside spec are scrapped, not shipped.

2. Reliability & Edge Sealing

Sealing processEvery cut edge receives a secondary UV-cure edge-sealing process (dispensed, not brushed) to restore the moisture/liquid-crystal barrier that the original panel's factory seal provided. This is applied uniformly along the entire cut length, not only at high-risk corners.

Reliability validationCut modules are qualified against the same environmental battery used for our standard industrial products (industrial-grade by default; consumer-grade screening available if your application allows a lower spec):

• 85°C / 85% RH (double-85) damp heat — sustained exposure test for seal integrity and moisture ingress

• High/low temperature storage & operating cycling (-20°C to 60°C per datasheet operating range)

• Thermal shock cycling — rapid transition testing at the sealed edge specifically, since this is the highest-risk zone for a cut panel

• Structural drop testing — module-level, to confirm the cut edge does not become a stress-concentration failure point

We can share environmental test summary data for comparable cut-panel programs on request under NDA.

Optical performance after sealingThe known failure modes for cut-and-sealed panels are edge light leakage and Mura/color shift near the seal line. Our backlight frame and seal thickness are tuned per cut ratio to keep the seal within the bezel/mask coverage area, so leakage and color shift are inspected as a pass/fail criterion during final QC — not left to visual sampling only.

3. Cost, Yield & Lead Time

Production capability

• In-house cutting, sealing, assembly and testing (no outsourced sub-processes for this step)

• 12,000+ units/month production capacity

• 12-month product warranty with continued engineering support

• CE / FCC / RoHS as standard; UL / CCC / EAC available on request
