28" Ultra-Wide Stretched Bar TFT LCD — Custom Cutting Solution

Model: P280IVN02.0 | Manufactured by HITULCD

Prepared for: overseas system integration engineers, procurement managers, and project leads evaluating custom-cut TFT LCD projects.

Product Overview

The P280IVN02.0 is a stretched bar display cut from a standard 28.0" a-Si TFT-LCD panel, delivering a resolution of 1920×360 (≈5.33:1 aspect ratio) at 1500 nits typical brightness. It is designed for retail shelf-edge displays, transit/bus passenger information bars, and embedded industrial equipment panels. The product is manufactured in-house by Shenzhen Hantu Jiashi Technology Co., Ltd. (HITULCD, established 2014), which offers end-to-end engineering support from prototype to volume production.

The sections below directly address the questions most commonly raised by overseas buyers during the evaluation stage of a custom-cut TFT module project: process feasibility, reliability/sealing, and cost/yield/lead time.

1. Process Feasibility & Cutting Method

Cutting Method Recommendation

Depending on the target size and tolerance requirements, our engineering team recommends one of two cutting methods after reviewing your specification:

• Mechanical wheel cutting — lower cost, suited to stable volume production, straight-line cuts with tolerances typically in the ±0.1–0.2 mm range.

• Ultrafast laser cutting (picosecond/femtosecond) — minimal heat-affected zone, better suited to irregular shapes or applications sensitive to micro-cracking, with tighter achievable tolerances.

The final method is selected based on the target dimensions, source panel model, and the vibration/shock conditions of the end application.

Routing & Circuit Clearance

Whether the cut line interferes with the Gate/Source routing or the active TFT array is the primary factor determining feasibility. To complete an initial feasibility review, we typically request:

• Target cutting dimensions and mounting position drawing (with tolerance requirements)

• Desired resolution and active display area

• Installation environment (touch requirement, bonding, metal frame mounting, etc.)

• Reference drawings or a comparable existing product, if available

Once received, our engineering team cross-checks the cut line against the Gate/Source line and IC bonding area on the source panel, then issues a feasibility report with a preliminary structural drawing.

Edge Finishing

Edge flatness and micro-crack control after cutting are critical to long-term reliability. We apply internal control standards covering chipping limits, edge grinding/chamfering, and sampling inspection rates — full parameters are provided with the sample report at the prototyping stage.

2. Reliability & Sealing

Sealing Process

After cutting, the exposed edge undergoes a secondary sealing process — standard practice is UV dispensing/sealing — to prevent liquid crystal leakage and moisture ingress, ensuring long-term seal integrity at the cut edge. For outdoor or high-humidity applications, additional frame structures or gasket sealing can be layered on top, depending on the actual use case.

Reliability Testing

Standard products are certified to CE / FCC / RoHS, rated for an operating temperature of -20°C to 60°C. For custom-cut projects, testing can be arranged according to the target application grade (consumer or industrial), including high-low temperature/humidity cycling (double-85 test), thermal shock, and structural drop testing. Benchmark test data and reports can be provided together with the sample batch for pre-production review.

Optical Performance (Mura / Light Leakage)

Optical consistency along the sealed cut edge is a key indicator of overall yield. Our backlight design and sealing process include dedicated optical inspection of the edge zone to avoid light leakage or color-shift Mura defects. Corresponding inspection data and edge-area samples can be provided at the prototyping stage for your confirmation.

3. Cost, Yield & Lead Time

For NRE cost, first-sample (20 pcs) lead time, and expected mass-production yield, we recommend submitting the target cutting dimensions and tolerance requirements so our engineering team can issue a written assessment specific to your design. Cut position and sealing method significantly affect yield, so generic figures would not accurately reflect your actual project.
