27.7" Cuttable Stretched Bar TFT LCD Module | 1920 × 216 | 500–1000 nits | OEM/ODM Custom Cut

Ultra-wide 8.9:1 bar display for OEM integration — trim one axis to your exact enclosure size, without tooling a new glass size.

HITULCD's 27.7-inch stretched bar TFT LCD module delivers a full-width 1920 × 216 pixel canvas in a slim, shelf-, rail- and fascia-friendly form factor. Built on a cuttable panel platform, the module can be trimmed along one axis to a non-standard dimension during OEM integration, with engineering-reviewed cut lines, controlled edge quality and a re-sealed edge for long-term reliability.

Designed for hardware engineers, project managers and sourcing teams building retail, transportation, industrial and signage equipment.

Key Features

• Ultra-wide 8.9:1 format – 1920 × 216 pixels, active area approx. 699.2 × 78.7 mm; sharp text, scrolling info and data strips

• Cuttable design – custom height/width on one axis, no new glass-size tooling; ideal for unique enclosure depth or shelf height

• High brightness 500–1000 cd/m² – configurable for indoor retail, covered transit and shop-window (semi-outdoor) environments

• Wide viewing angle – 178° / 178° (H/V) typical, consistent image at oblique mounting angles

• Flexible interfaces – LVDS / eDP panel interface; HDMI / VGA / industrial controller board options

• Edge-sealed and validated – UV-cured edge sealing, edge-zone light-shield treatment and an IEC 60068-based reliability plan

• Full OEM/ODM support – custom brightness, interface, cable, bracket, cover glass/touch, logo and private-label packaging

Technical Specifications

Values are typical at 25 °C unless noted. Final specifications are confirmed on the project datasheet and approval drawing.

Cuttable Platform: How It Works

The 27.7" bar is produced from a large-format cell that can be trimmed on one axis to a custom dimension. The cut line is placed outside the active area and clear of the driver and routing zones. The cut edge is then re-sealed, optically masked and validated.

Which cutting method should I choose?

Our engineers recommend the method after reviewing your drawing, target tolerance and volume.

Engineering Feasibility Review (Before Quotation)

Every custom cut goes through a design review so there are no surprises at sampling.

We check:

• Whether the requested size interferes with Gate / Source routing, fan-out, shorting bars or the TFT array area

• The distance from the cut line to the seal line and active area (minimum safe margin)

• Driver IC / FPC / COF position and backlight LED bar position after cutting

• Mechanical fit: bezel, bracket, cover glass and connector location

• Optical stack: polarizer size, backlight (LGP, films, reflector) trimmed to match

To start, please send:

1. Target active area and outline dimensions, with tolerance

2. Enclosure or 2D/3D mechanical drawing (STEP / DXF / PDF)

3. Required brightness, interface and operating temperature range

4. Touch / cover glass / bonding requirements (if any)

5. Estimated annual volume and target price range

We return a feasibility report and approval drawing (with cut-line position) for your sign-off before any sample build. Panel-level layout data is shared under NDA.

Edge Sealing and Reliability

A cut cell exposes a new edge, so sealing quality determines long-term reliability. HITULCD applies a controlled edge-sealing process to prevent liquid-crystal leakage and moisture ingress.

Sealing process

• Automated dispensing of UV-curable, low-moisture-permeability edge sealant along the cut edge

• UV cure followed by thermal post-cure for full cross-linking

• Optional secondary barrier (additional sealant layer) for high-humidity or outdoor-adjacent applications

• 100 % visual inspection of seal continuity; sampling inspection under microscope

• Black edge masking to block stray light (see Optical Performance)

Standard validation plan (IEC 60068 series)

Pass criteria: no LC leakage, no seal delamination or moisture bubbles, no new Mura, no functional failure, brightness change within ±10 %, and the module remains within mechanical tolerance.

Project-specific test reports are provided together with engineering samples. Consumer-, commercial- or industrial-grade test levels can be selected to match your product class.

Optical Performance at the Cut Edge

Light leakage, color shift and edge Mura are the main risks in cut modules. We manage them at design level:

• Backlight matched to the cut size – LGP, reflector and optical films are trimmed and aligned to the new outline

• Edge light-shield – black light-blocking tape/frame around the cut edge and seal to stop leakage

• Optimized non-active margin – a controlled border between the cut edge and the active area absorbs edge effects

• Uniformity control – brightness uniformity ≥ 80 % (9-point method, typical); edge Mura evaluated against a limit-sample standard

• Optional optical bonding – OCA/LOCA cover glass improves contrast, sunlight readability and edge appearance

Frequently Asked Questions

Which cutting method do you recommend — mechanical or laser?

Mechanical wheel cutting suits standard tolerances (±0.20 mm) and cost-sensitive volume. Ultrafast laser cutting gives tighter tolerance (±0.10 mm) with lower chipping. We recommend one after reviewing your drawing, tolerance and volume.

Will the new size interfere with Gate/Source routing or the TFT array?

We place the cut line outside the active area and clear of the driver and routing zones. Feasibility is confirmed with a layout review before any sample is built. We need your target dimensions, enclosure drawing and key electrical/optical requirements.

What is the glass edge quality after cutting?

Typical chipping is ≤ 0.20 mm (wheel) or ≤ 0.10 mm (laser), with no chips reaching the seal or active area. Edges are inspected under microscope, and edge grinding or chamfering is optional.

How is the cut edge sealed against leakage and moisture?

By automated dispensing of UV-curable low-moisture-permeability sealant, followed by UV and thermal post-cure. An optional secondary barrier is available for high-humidity applications.

Can the cut module pass industrial reliability tests?

Our standard plan follows the IEC 60068 series: high/low-temperature storage, damp heat (up to 85 °C / 85 % RH), thermal shock, vibration, shock and packaged drop. Test reports are provided per project.

Is edge light leakage or color shift a concern?

It is controlled by trimming the backlight to size, applying black edge light-shield material and reserving an optimized non-active margin. Edge appearance is checked against a limit-sample standard.

What are NRE, sample time and MOQ?

NRE is quoted per project and may be credited against a volume order. 20 pcs of engineering samples typically take 2–3 weeks after drawing approval. MOQ for custom-cut modules is 50 pcs.

What yield can I expect in mass production?

We target ≥ 95 % first-pass yield at module level, tracked lot by lot, with the final figure reviewed after pilot build.

Do you offer OEM/ODM and private label?

Yes. Brightness, interface, driver board, brackets, logo and packaging can all be customized.
