24" Narrow Ultra-Wide TFT LCD Module (Cut-to-Size Bar Display)

Model: QV240FBM-N10 | Manufactured by HITULCD (Shenzhen Hantu Jiashi Technology Co., Ltd.)

This technical brief is prepared for overseas engineers, procurement managers and project owners evaluating custom-cut TFT bar displays. It addresses the three areas most commonly raised in RFQs — cutting process feasibility, reliability/sealing, and cost/yield/lead time — so your team can complete internal evaluation before a formal quotation is issued.

1. Product Overview

The 24" Narrow Ultra-Wide TFT LCD Module (QV240FBM-N10) is produced by precision-cutting a 27" mother glass panel into a 1/3 stretched bar format, resulting in a 1920×360 resolution display with a 5.33:1 aspect ratio. It is designed for retail shelf/cooler signage, checkout bar displays, bus passenger information, and building directory applications.

2. Cutting Process & Feasibility Assessment

For ultra-wide aspect ratio bar displays, we use a secondary precision cutting process on mother glass, with the following controls applied at the pre-evaluation stage:

2.1 Cutting Method Recommendation

Two cutting methods are available, selected based on target size, tolerance requirements, and edge-sensitivity of the application:

A formal recommendation is issued in writing (Cutting Feasibility Confirmation) prior to sampling, based on glass thickness, proximity of the cut line to circuit routing, and the customer's yield/edge-strength requirements.

2.2 Circuit Routing Clearance

Before quotation and sampling, we confirm whether the proposed cut line intersects the Gate/Source driver routing area or the active TFT array region of the mother panel.

To complete this feasibility check, please provide:

• Target finished dimensions, active display area, and tolerance requirements

• Mechanical drawing / mounting hole layout (if structural integration is required)

• For non-standard cuts: a sketch or dimensioned drawing showing the intended cut line relative to the mother panel outline

Our engineering team will cross-reference this against the mother panel's Gate/Source routing layout and issue a written Cutting Feasibility Confirmation before sampling proceeds.

2.3 Edge Finishing Standard

• Cut edges are processed with chamfering + polishing, controlling edge flatness and micro-crack propagation within industry-standard limits (typically edge chipping ≤ 0.1 mm per IEC 60068-2-27 mechanical robustness reference).

• Edge finishing precision can be adjusted according to the target reliability grade (Consumer / Industrial); inspection reports are provided with sample shipments.

3. Reliability & Sealing Assurance

3.1 Sealing Process

Cutting exposes the polarizer/glass interface at the edge. We apply a UV-cure dispensed edge sealant as a secondary sealing process to prevent liquid crystal leakage and moisture ingress. Sealing consistency is verified through batch-level microscopic inspection, with before/after imagery available on request.

3.2 Reliability Testing

Cut-and-sealed TFT modules are validated against standard Consumer-grade or Industrial-grade reliability protocols (selected based on target application), including but not limited to:

Benchmark data from comparable cutting projects (test duration, cycle count, pass criteria) can be shared under NDA once a formal inquiry with target application is received.

3.3 Optical Performance

The sealed edge region is process-optimized to avoid visible light leakage or color shift (Mura) under normal viewing conditions. For applications with close-proximity viewing (e.g., retail shelf-edge displays), tighter optical acceptance criteria can be defined and applied at the sampling stage.

4. Cost, Yield & Lead Time

Supply Capability

• Monthly capacity: 12,000+ units

• Standard lead time: 2–3 weeks; custom projects: 4–6 weeks

• Supports phased engagement — sampling → small-batch trial → mass production — to reduce upfront risk

5. Supplier Qualification Snapshot

6. Information Needed to Proceed

To receive a feasibility assessment and quotation within 1–2 business days, please provide:

1. Target finished dimensions and mounting tolerance (drawing or sketch)

2. Application and target reliability grade (Consumer / Industrial)

3. Expected sample quantity and annual mass production volume

4. Interface requirements (HDMI / VGA / LVDS) and touch function (if required)

Note: Values marked as "typical" or "industry-standard reference" (e.g., test cycle counts, edge chipping tolerance, yield range) are based on common industry practice for cut-panel TFT modules and should be confirmed against project-specific test reports at the sampling stage.
