23.8" Bar-Form LCD Module Panel Display (Cuttable / Stretched Bar Series)

Custom Ultra-Wide Aspect Ratio TFT-LCD Module | OEM/ODM | MOQ 50 pcs

Overview

The 23.8" Bar-Form LCD Module is built from a standard 23.8" a-Si TFT-LCD panel (1920×1080 FHD base cell) that is precision-cut along one axis to produce a non-standard, elongated "stretched bar" form factor — ideal for retail shelf-edge signage, transportation displays, elevator/lobby panels, vending fronts, and industrial control interfaces where a conventional 16:9 panel simply won't fit the available mounting space.

Because the cut is performed on a mass-produced base cell rather than a fully custom tooling run, customers get near-custom mechanical geometry at a fraction of the cost and lead time of a ground-up custom panel design.

Note: Final active area, resolution, and aspect ratio depend on the customer's specified cut line and are confirmed during the DFM (Design-for-Manufacturing) review. The values below reflect the base 23.8" panel and typical cut ranges; final specification is issued per project via a signed spec confirmation sheet.

Key Features

• Custom aspect ratio — trimmed on one axis (width or height) from the base 23.8" FHD cell; typical resulting ratios include 8:1, 16:3, 16:4.5, and other bar/stretched formats per customer drawing

• High-brightness options — 500–1,000 nits standard range for mixed-light retail/transit environments; up to 1,500–2,000 nits available for semi-outdoor or window-facing installations¹

• Interface flexibility — HDMI, LVDS, or eDP signal input available; driver board re-mapping included where the cut removes part of the active array

• Industrial-grade reliability — wide operating temperature options and long-life LED backlight (see Reliability section)

• OEM/ODM support — custom brightness, resolution/timing, interface, cover lens bonding, logo branding, and private-label packaging

• Optional touch — PCAP touch overlay available on request (with optical bonding for outdoor/high-vibration use)

Technical FAQ — For Engineers, Procurement & Project Managers

1. Cutting Process & Feasibility

Q: What cutting method do you recommend, and what tolerances can I expect?Two processes are available depending on precision and volume requirements:

• Mechanical wheel (scribe-and-break) cutting — lower cost, shorter lead time, suitable for straight-line cuts outside the active display area; typical tolerance ±0.2–0.3 mm.

• Ultrafast (UV/femtosecond) laser cutting — higher precision, cleaner edge, minimal heat-affected zone and micro-cracking; typical tolerance ±0.05–0.1 mm; recommended when the cut line approaches the active area or a driver IC.

The recommended method is confirmed after reviewing your target dimensions and tolerance requirements.

Q: Will the cut interfere with the Gate/Source trace routing or the TFT array?It can, if the cut line falls inside the routing margin. Our DFM review checks the cut line against the base panel's Gate driver, Source driver, and TFT array boundaries before quotation to confirm the retained active area is fully addressable and free of open/short risk.

Q: What drawings or parameters do you need from us to assess feasibility?Typically:

• Target outline dimensions (or the finished bar/panel drawing, DWG/DXF/STEP)

• Required active area and orientation (portrait/landscape)

• Interface preference (HDMI/LVDS/eDP) and connector location constraint, if any

• Target brightness and operating temperature range

• Intended mounting method / enclosure depth

• Application environment (indoor, semi-outdoor, vibration/shock exposure)

Q: What edge-flatness and micro-crack standards apply after cutting?Edge inspection follows standard optical-glass edge criteria: no visible chipping beyond a defined edge zone (typically ≤0.1 mm chip depth under laser cutting), no through-thickness cracks, and edge flatness controlled to avoid stress concentration during subsequent handling and mounting. Full inspection criteria are documented in the process spec issued after sample approval.

2. Reliability & Edge Sealing

Q: How do you seal the cut edge against liquid crystal leakage and moisture ingress?A secondary edge-sealing process is applied after cutting — typically UV-curable dispensed sealant applied along the cut edge, cured under UV light to form a moisture and LC-leakage barrier. Sealant selection and dispensing pattern are validated against the reliability test plan below before mass production release.

Q: Can the cut module pass standard reliability testing, and do you have benchmark data?Cut modules are tested against the same class of environmental and mechanical standards used for standard TFT-LCD modules, for example:

• Damp heat (double-85 / "85/85") test — IEC 60068-2-78 or JEITA ED-4701/100, typically 85°C / 85% RH for 96–500 hours depending on grade

• Thermal shock / temperature cycling — IEC 60068-2-14, e.g., −20°C ↔ +60°C or −30°C ↔ +70°C, multiple cycles

• High/low temperature storage & operation — per the operating/storage temperature range selected

• Mechanical shock / drop test — IEC 60068-2-27 (shock) or ISTA/MIL-STD-810 style drop test for packaged units

Whether the module targets consumer-grade or industrial-grade qualification depends on your application; the applicable test plan and pass/fail criteria are agreed at the project kickoff and benchmark reports from comparable prior cutting projects can be shared under NDA.

Q: Is there any risk of light leakage or color shift (Mura) near the sealed edge after cutting?This is a known risk area for cut panels and is specifically why edge sealing and backlight re-masking are controlled steps in the process. With correct laser-cut edge quality and sealant dispensing, edge light leakage and Mura are controlled to within the same acceptance criteria used for standard panel edge inspection. Engineering samples are used to visually and instrumentally verify this before mass production sign-off.

3. Cost, Yield & Lead Time

Q: What is the typical NRE cost and first-sample lead time?NRE (cutting fixture, DFM review, and process validation) is quoted per project based on cut complexity and cutting method. As a general industry reference, first-article samples (around 20 pcs) typically require 2–4 weeks from drawing confirmation to sample shipment; exact NRE and lead time are confirmed in the formal quotation.

Q: What yield should we expect in mass production, and what is the MOQ?Mechanical wheel cutting typically yields in the 85–90% range; laser cutting typically yields 90–95%+, depending on cut geometry and proximity to the active area. MOQ for custom-cut panels is 50 pcs; production lead time and yield commitments are formalized after the engineering sample is approved and the process is locked.
