48.5 Inch Bright Stretched LCD Panel for Passenger Information

48.5 Inch Bright Stretched LCD Panel for Passenger Information

This 48.5-inch 1920 × 360 module combines configurable 500–5000 cd/m² luminance, a 4000:1 contrast ratio, a matte 3% haze surface and 51-pin LVDS signaling for long-format transit and commercial information systems.

Product Summary

The Bright Stretched LCD Panel for Passenger Information gives equipment designers a 1209.6 × 226.8 mm panoramic active area for route sequences, platform notices, arrival information, wayfinding and banner-style media. Its 1920 × 360 raster uses available width without the unused vertical space associated with a conventional 16:9 screen.

The module uses an a-Si TFT-LCD structure, operates at 60 Hz and supports a specified 16.7M/1.07B color path. A 4000:1 contrast ratio and 89°/89°/89°/89° raw viewing data support public-facing layouts observed from different positions.

A matching 51-pin connector does not guarantee LVDS timing, voltage, channel mapping, bit depth or pin compatibility.

A configurable 500–5000 cd/m² range must be converted into one approved production luminance before optical, power and thermal release.

The 1221 × 252.2 × 33.5 mm outline controls enclosure fit; the active area controls visible pixel placement.

Key Specifications

The principal technical values are defined in the product specification. The storage-temperature revision requires confirmation before final release.

Native 1920 × 360 Content Planning

Route and Timetable Layouts

The ultra-wide raster is suited to station routes, departure sequences, service messages and commercial banner content. Use the native 1920 × 360 canvas rather than scaling a 16:9 source, because letterboxing or uncontrolled cropping can reduce the available text height.

Define character height, viewing distance and line count before UI approval. Information read by moving passengers should use clear hierarchy, short labels and enough spacing between route names, times and status indicators.

Controller Output and Pixel Mapping

Confirm pixel clock, horizontal and vertical totals, polarity, mapping convention and connector orientation with the approved timing file and complete pin assignment.

The specified 16.7M/1.07B color value should also be reconciled with the controller path. An 8-bit LVDS description does not by itself confirm every panel-side color-processing configuration.

Configurable Luminance and Optical Qualification

Lock One Ordered Brightness

Choose one level within the 500–5000 cd/m² range according to ambient light, front-window transmission, viewing distance, operating schedule and enclosure cooling. Record the nominal value, tolerance, measurement point and dimming method in the purchase specification.

Re-test the selected production configuration in the intended enclosure. Different luminance versions can have different power and thermal requirements.

Matte Surface and Front-Window Stack

The panel has a matte surface with 3% haze. Finished-system readability also depends on protective glass, air gaps, optical bonding, coatings and installation angle.

Test the complete stack under representative lighting. A panel rating alone does not establish sunlight readability after front glass, contamination and enclosure geometry are introduced.

Integrating the Bright Stretched LCD Panel for Passenger Information

51-Pin LVDS Qualification

The interface is defined as two-channel, 8-bit LVDS on a 51-pin connector. Verify the complete pin definition, channel mapping, bit convention, supply pins, grounds, connector pitch, mating part and cable orientation.

Controller selection should use the approved timing and pinout, not connector count alone. Prototype with the intended cable before releasing the production harness.

12.0 V Panel Input

The nominal panel input is 12.0 V. Panel current, backlight voltage, current, enable logic, dimming input and startup sequence are not specified.

Request the model-specific electrical document before power-board release. Keep panel supply and backlight-driver requirements as separate design items until confirmed.

Mechanical and Environmental Integration

Enclosure Fit and Long-Panel Support

The 1221 × 252.2 × 33.5 mm physical size and 4.47 kg weight require a rigid, evenly supported structure. Long displays are sensitive to cabinet twist and local pressure, so support should be distributed.

Use the 1209.6 × 226.8 mm active area for content alignment. Confirm bezel opening, mounting points, keep-outs, connector position and tolerances before cutting the front frame.

Temperature and Protection Boundaries

The operating range is −20°C to +70°C. Use −30°C to +80°C as the provisional storage range, but an older specification revision gives a narrower range; the approved order document must control qualification.

Temperature capability does not prove waterproofing, impact resistance or vibration grade. Those properties belong to the completed system and require separate evidence.

Application Fit and Configuration Options

Passenger Information and Public Guidance

The Bright Stretched LCD Panel for Passenger Information is suited to railway platforms, metro stations, bus terminals, airport wayfinding and arrival boards. Its format supports route progress, platform changes, timetable bands and public alerts where a standard-height screen would use space inefficiently.

Commercial and Industrial Information Zones

Other project directions include EV charging information, fuel-dispenser media, retail window strips, QSR menu bands, smart-city information points, factory HMI headers and control-room dashboards. Each application requires its own luminance, protection, controller and thermal review.

Direct-lit or side-lit backlighting may be reviewed as a customization route. Other options can include fixed luminance selection, LVDS cable and controller matching, cover glass, AR/AG/AF treatment, optical bonding, enclosure adaptation, mounting and branding. Custom configurations are generally reviewed from 500 pieces, subject to tooling, material availability and the requested specification. Samples and standard-module quantities are confirmed separately.

Procurement Checklist

• Confirm the assigned model and supplier revision.
• Fix one luminance level within the 500–5000 cd/m² range.
• Provide native 1920 × 360 timing and the complete 51-pin assignment.
• Confirm two-channel 8-bit mapping and connector orientation.
• Define the 12.0 V panel current and all backlight electrical data.
• Provide the approved mechanical drawing and mounting points.
• Validate the 1221 × 252.2 × 33.5 mm enclosure fit.
• Design distributed support for the 4.47 kg module.
• Define the front-window material and optical targets.
• Confirm touch, protective-glass or non-interactive architecture.
• Lock operating and storage temperature revisions.
• State sample quantity, qualification plan and annual demand.
