46.6" Bar LCD Module for Passenger Information Systems

Model: PR466KT01-1 | Ultra-Wide Stretched Bar Display | 3840×120 (≈32:1)

Manufacturer: Shenzhen Hantu Jiashi Technology Co., Ltd. (HITULCD)Established: 2014 (11+ years in operation) | Certifications: ISO9001, CE, FCC, RoHS, REACH, WEEE

1. Product Overview

The PR466KT01-1 is a 46.6-inch ultra-long stretched bar TFT-LCD module purpose-built for passenger information displays (PIS) — bus/rail destination signs, overhead announcement bars, platform information strips, and other narrow-format transit signage. Unlike a standard panel cut down after the fact, this is offered as an FOB open-cell native long-format panel, giving integrators a display designed from the array level for the 32:1 aspect ratio rather than a secondary-processed short panel.

Note for engineering review: This is a bare open-cell panel (glass + COF), not a finished module. Backlight assembly, driver board, and mechanical housing are configured to your project during the customization stage — see Section 4.

2. Why This Format for Transit PIS Projects

• True long-aspect array design — avoids the optical and structural compromises of aftermarket-cut short panels in the destination-sign / overhead-bar form factor.

• Wide viewing angle (89° all directions) for readability from platform or aisle sightlines.

• 700-nit brightness with 3000:1 contrast — legible under vehicle interior lighting and near-window ambient light.

• Industrial temperature range (0–50°C operating) suited to transit-cabin thermal cycling.

• Direct factory engineering access — specification, cutting, and backlight requirements are reviewed with our technical team rather than through a trading intermediary.

3. Technical Process & Feasibility (for Engineering Review)

For buyers evaluating a custom-cut or custom-length bar panel derived from a standard-size mother glass (a common path for non-standard PIS bar sizes), our engineering team works through the following review points before quotation:

3.1 Cutting Process

• Two cutting methods are available depending on tolerance and glass thickness: mechanical wheel scribing (lower cost, larger MOQ-friendly, tolerance typically ±0.3mm) and ultra-fast laser cutting (tighter tolerance, cleaner edge, preferred for thin substrates or tight display-area constraints).

• Method selection depends on final panel thickness, required tolerance, and target display-area boundary — this is confirmed during design review, not assumed upfront.

3.2 Circuit & Array Clearance

• Every custom cut is checked against the source panel's Gate/Source trace layout and active TFT array boundary before a cutting line is approved, to confirm the new outline does not intersect active circuitry.

• To run this feasibility check, our team typically requests: (1) target outline dimensions and tolerance, (2) preferred active area / display area, (3) mounting or bezel constraints, and (4) the source panel model if a specific mother panel is being evaluated. Draft drawings (DWG/DXF) speed up this step.

3.3 Edge Quality

• Post-cut edges are inspected against defined flatness and micro-crack control standards before proceeding to sealing; edge chipping and crack-propagation risk are evaluated as part of the same review.

3.4 Sealing & Moisture Protection

• Cut edges receive a secondary sealing process (UV-cure dispensing along the cut edge, with alternative sealants available depending on project environment) to protect against liquid crystal leakage and moisture ingress at the exposed edge.

3.5 Reliability Validation

• Cut-and-sealed modules are put through standard reliability testing appropriate to the target grade (consumer or industrial), including double-85 (85°C/85%RH) high-temperature/humidity test, high/low temperature cycling (thermal shock), and structural drop testing. Benchmark data from comparable past cutting projects can be shared under NDA during technical review.

3.6 Optical Performance at the Cut Edge

• Edge-zone optical behavior (light leakage and color-shift/Mura risk near the sealed boundary) is a known risk area for cut panels and is specifically inspected during qualification, with acceptance criteria confirmed per project.

8. Next Step for Technical Evaluation

To move a custom-cut program to formal quotation, please share:

1. Target glass/module outline dimensions and required tolerance

2. Preferred active display area and mounting/bezel constraints

3. Target grade (consumer vs. industrial) and relevant reliability test standards

4. Estimated annual volume and sample quantity for first article

Our engineering team will confirm cutting method, sealing process, feasibility, and indicative NRE/timeline based on the above.
