1. Product Overview

The 28.6-inch stretched bar LCD module is built from a proven large-format TFT-LCD panel that has been precision-cut to an ultra-wide 32:9 aspect ratio. This format fits applications where a standard 16:9 display simply does not: shelf-edge displays, bus and rail passenger-information systems, vending machine headers, elevator and lobby signage, control-desk status bars, and panoramic industrial HMIs.

Unlike a standard catalog panel, this module is offered in a cuttable configuration. If your enclosure, shelf, or industrial design requires a non-standard width or height, our engineering team can trim the panel to your target dimensions while maintaining optical performance, sealing integrity, and long-term reliability.

Every project starts with a free engineering feasibility review (see Section 4), so you know the cut is safe, sealed and manufacturable before you commit to tooling or samples.

2. Key Features

3. Technical Specifications

Specifications are typical values for the standard configuration and may vary slightly by panel source and customization. A signed-off datasheet and 2D/3D drawing are provided with every quotation.

4. Custom Cutting Service: Engineering Capability

Cutting a finished TFT-LCD panel is a precision process, not simply a matter of trimming glass. Below is how we address the questions our engineering and procurement customers ask most.

4.1 Cutting Method, Dimensions and Tolerance

We select the process based on your target dimension, edge quality requirement and volume:

Our engineers recommend the method during the feasibility review. Typical cut increments and minimum remaining panel size depend on the source panel structure (see 4.2).

4.2 Circuit Avoidance & Feasibility Review (Gate / Source / TFT Array)

The cut line must never cross or come too close to the active area, frame sealant, or gate/source fan-out wiring. Before any cutting, we perform a cut-line feasibility check against the original panel design:

• Confirm the keep-out zone around the TFT array, seal line and GOA/gate driver area

• Confirm the target dimension does not interfere with source/gate lines or driver IC/FPC bonding regions

• Confirm backlight (LED bar position, light guide plate) can be resized without brightness or uniformity loss

• Confirm mechanical fit, mounting holes and bezel design

To start the review, please send us:

1. Target outline size and tolerance (2D DXF/PDF or 3D STEP file preferred)

2. Which edge(s) are to be cut and required remaining active-area position

3. Required brightness, interface and operating temperature range

4. Enclosure/bezel concept and mounting method

5. Target annual volume and application

We will return: a marked-up panel drawing showing the permitted cut zone, a recommended cutting method, and a feasibility conclusion, typically within 3 working days.

4.3 Edge Quality: Flatness and Micro-Crack Control

• Post-cut edge inspection under microscope (typically 50×–100×)

• Edge chipping and micro-crack criteria defined per approved drawing (typical acceptance: no crack extending toward the seal line; chipping ≤ 0.2 mm mechanical / ≤ 0.1 mm laser)

• Optional edge grinding/chamfering to relieve stress and improve handling safety

• 100% visual inspection of cut edges; sampling-based cross-section checks for lot approval

5. Sealing & Reliability Assurance

5.1 Edge Sealing Process

After cutting, exposed cell edges are re-sealed to prevent liquid crystal leakage and moisture ingress:

• UV-curable acrylic/epoxy edge sealant applied by automated dispensing for controlled, repeatable bead geometry

• Optional secondary protective layer (moisture-barrier silicone or equivalent) for high-humidity or vehicle environments

• Polarizer edge treatment and light-shield tape at the cut border

• 100% inspection of seal coverage; leakage check after cure and after reliability testing

5.2 Reliability Testing

Cut modules are validated against standard industrial-grade test conditions. Typical test benchmarks applied to cut-panel projects:

Test reports from comparable cutting projects can be shared under NDA upon request. For new dimensions, we recommend running your project-specific test plan during the sample stage.

5.3 Optical Performance After Cutting

• Light leakage / edge Mura: controlled through backlight LED-bar and light-guide plate re-trimming, edge light-shielding tape and black-edge treatment

• Color shift: verified against original panel white-point and uniformity limits

• Luminance uniformity: typically ≥ 75% (9-point measurement) for standard configuration; customer-specific targets can be agreed on the approved specification

• 100% optical inspection of edges under dark-room conditions before shipment

6. Customization Options (OEM / ODM)

7. Typical Applications

• Public transport: bus, tram, train and metro passenger information displays

• Retail: shelf-edge displays, supermarket gondola displays, menu boards, promotional bars

• Vending & self-service: vending machines, kiosks, ticketing machines

• Digital signage: window-facing displays, lobby and elevator information screens

• Industrial & control: control-desk status bars, machinery HMIs, monitoring dashboards

• Hospitality & entertainment: restaurant menus, stage and event displays

8. Cost, Lead Time & Ordering

Pricing depends on volume, brightness, cut dimensions and accessories. Contact us for a project-specific quotation.

9. Quality & Compliance

• Materials compliant with RoHS and REACH

• Incoming, in-process (IPQC) and outgoing (OQC) inspection following AQL sampling standards

• Full batch traceability by serial number and lot code

• Support for customer audits and NPI (New Product Introduction) reviews

• ESD-safe production and packaging

10. Frequently Asked Questions

Q1. Which cutting method do you recommend: mechanical or laser?For straight cuts and cost-driven volumes, mechanical scribing is usually sufficient (±0.20 mm). For tighter tolerance, cleaner edges or shaped contours, ultrafast laser cutting is recommended (±0.10 mm). We will advise during the feasibility review.

Q2. Will my target size interfere with the gate/source lines or the TFT array?Not if it stays within the permitted cut zone. We overlay your target outline on the original panel design and confirm the safe cut line before any sample is built. Please send your 2D/3D drawing and the edge(s) you need trimmed.

Q3. How do you control edge micro-cracks?By optimizing cutting parameters, optional edge grinding/chamfering, microscope inspection, and post-cut stress relief. Acceptance criteria are defined and signed off on the approved drawing.

Q4. How is the cut edge sealed against moisture and leakage?With automated UV-cure edge sealing, optionally followed by a secondary moisture-barrier layer. Every project is validated through damp-heat and thermal-shock testing.

Q5. Can cut modules pass industrial reliability tests?Yes. Typical validation includes damp-heat (60 °C/90% RH or 85 °C/85% RH), thermal shock, high/low-temperature storage, vibration and packaged drop testing. Benchmark data from similar projects is available under NDA.

Q6. Will cutting cause light leakage or color shift at the edges?Edge light leakage and Mura are controlled by re-trimming the backlight, adding light-shield tape and inspecting under dark-room conditions. Color shift is checked against the original panel's white-point and uniformity limits.

Q7. What are the NRE, sample lead time and MOQ?Typical NRE is USD 1,500–5,000 (refundable/waived on mass production), first 20-pcs samples take 2–3 weeks, and MOQ for custom-cut projects is 50 pcs.

Q8. What yield can I expect in mass production?Typically 95% or better once the process is stabilised. Sample-stage data is used to give you a project-specific figure.

Q9. Is the LED driver / controller board included?Not by default. We supply compatible LED driver boards and HDMI/VGA/AV-to-LVDS boards, or a full Android media-player solution, as options.

Q10. Can I get a non-standard brightness, interface or housing?Yes. We provide full OEM/ODM services covering brightness, interface, touch, cover glass, housing, branding and private-label packaging.
