HITULCD manufactures this 23.1" ultra-wide bar-format TFT LCD module (1920 x 158 resolution, >3:1 aspect ratio, 500 nits) entirely in-house — from panel cutting through sealing and reliability testing — for integrators building digital signage, retail shelf-edge displays, transportation passenger information bars, and kiosk systems.
23.1" Ultra-Narrow Wide Aspect TFT LCD Module
Model S231AJ1-LE1
Factory-direct custom-cut stretched bar display for OEM & project integration
HITULCD manufactures this 23.1" ultra-wide bar-format TFT LCD module (1920 x 158 resolution, >3:1 aspect ratio, 500 nits) entirely in-house — from panel cutting through sealing and reliability testing — for integrators building digital signage, retail shelf-edge displays, transportation passenger information bars, and kiosk systems. Unlike third-party rework shops that source cut glass externally, our cutting, edge-sealing, and QA processes are performed under one roof, giving OEM and project buyers a single accountable source for design, samples, and volume production.
1. Cutting Process & Design Feasibility
We evaluate every custom-cut request against the source panel's Gate/Source trace layout and active TFT array before quoting, so buyers don't discover routing conflicts after tooling starts.
• Cutting method: Mechanical wheel cutting for standard tolerances and cost-sensitive volume programs; ultrafast laser cutting for tighter dimensional tolerances (±0.1mm class) or complex profile cuts. Method is selected jointly with the customer's drawing during DFM review, not fixed in advance.
• What we need from you before feasibility confirmation: Target cut dimensions and tolerance, active area (A.A.) requirement, mechanical/mounting drawing (DXF/PDF), and target volume — this lets our engineering team confirm cut feasibility and quote NRE within 2–3 business days.
• Edge finishing standard: Ground and polished cut edges; micro-crack propagation controlled to IEC 60068-2-27-compliant mechanical robustness levels. Edge inspection records (visual + dimensional) are available on request.
2. Reliability & Edge-Sealing Assurance
• Sealing process: Cut edges are sealed with UV-cure edge sealant (dispensed application) to prevent liquid crystal leakage and moisture ingress at the cut line — this is the critical difference between a properly engineered cut module and a raw cut panel.
Reliability test benchmarks (typical/reference values for this class of industrial TFT module — full test reports available on request for qualified projects):
• Temperature & Humidity (Double 85 test): 85°C / 85% RH, 96–240 hours, no delamination or leakage.
• Thermal shock: –20°C to 60°C, 2 cycles/hour, 24–96 hours per IEC 60068-2-14.
• Drop test: 76cm free-fall onto packaging, per ISTA/IEC 60068-2-32, no structural or display failure.
• Operating temperature: 0°C ~ 50°C | Storage: –20°C ~ 60°C (per datasheet).
• Backlight lifetime: 30,000 hours (WLED, L50).
• Optical performance after sealing: Cut-edge regions are inspected for light leakage and Mura/color-shift defects under darkroom conditions before shipment, ensuring the sealed edge matches the main display area optically.
3. Cost, Yield & Program Timeline
• NRE / tooling cost: Typically USD 500–2,000 for a standard mechanical cut program depending on tolerance and fixture requirements; laser-cut or complex-profile programs are quoted individually after DFM review.
• First sample lead time: 15–20 working days for a 20pcs sample run (mechanical cutting); laser cutting or tighter-tolerance programs typically add 5–10 working days.
• Mass production yield: Custom cut/seal programs of this type typically run 92–97% yield once the process is qualified on your specific cut profile; final figure is confirmed after the pilot run (PPAP-style qualification recommended for programs >5,000 units/year).
• MOQ: Standard spec — 1 unit (sample-friendly for evaluation). Custom cutting, brightness, or bezel changes may raise MOQ; confirmed at quotation stage.
• Lead time: 2–3 weeks standard spec | 4–6 weeks custom-cut programs.
