3.6 Inch Round Vehicle Instrument TFT LCD Panel for Gauges

3.6 Inch Round Vehicle Instrument TFT LCD Panel for Gauges

The Round Vehicle Instrument TFT LCD Panel combines a 544 × 506 raster, an IPS normally-black display mode, DPI input and an 800 cd/m² luminance target. It suits compact instrument faces after interface, mechanical and optical qualification.

Product Summary

The active display area measures 89.76 × 83.49 mm and uses an RGB vertical-stripe arrangement with 16.7M colors. A white LED backlight supports the selected high-luminance configuration, while the component temperature range is specified from −30°C to +85°C for operation and storage.

Round 544 × 506 Display Geometry

Interface graphics should be prepared at the native 544 × 506 resolution.

800 cd/m² Optical Boundary

Final readability still depends on the cover lens, air gap or optical bonding, surface reflections, polarizer behavior, backlight drive and thermal conditions. Approve readability on the completed front stack.

Key Specifications

Circular UI Planning for Gauge Interfaces

Map the Native Raster to the Round Opening

Create the UI at 544 × 506 pixels and overlay the approved active-area mask before placing speed values, warning icons, battery indicators or status rings. This prevents clipped information near the circular perimeter.

Preserve a Functional Safe Area

Keep high-priority text and telltales away from the outer edge. Use the confirmed viewing-area and enclosure drawings to account for bezel overlap and assembly tolerances.

Round Vehicle Instrument TFT LCD Panel Integration

The exact data width, clocking method, synchronization signals, polarity, voltage levels and initialization responsibilities are not established by the interface label alone.

Confirm the 40-Pin Signal Map

A matching connector does not prove electrical compatibility. Confirm every pin, contact side, FPC orientation, pixel-data mapping, clock limits, sync or data-enable mode, reset behavior and power domain before controller-board layout.

Keep the ST72566 Role Bounded

ST72566 is identified as the display control IC. The part number does not by itself prove a compatible firmware package, host-side register sequence or power-up procedure. Use the approved timing documentation for the ordered revision.

Mechanical Fit and Drawing Control

Reconcile the Two Outline References

The summary table gives 98.36 × 94.37 mm, while the mechanical drawing shows approximately 98.88 × 94.12 × 7.80 mm. The production drawing must control enclosure tooling and alignment.

Protect the FPC Bend Region

Define the bend radius, stiffener location, connector keep-out, insertion direction and strain relief so the enclosure does not load the FPC or shift the panel.

Temperature and Optical Qualification

Validate the Wide-Temperature Range at System Level

The component is specified for −30°C to +85°C operation and storage. Test the assembled product under its actual thermal and mechanical profile.

Check Brightness Behind the Finished Cover

An 800 cd/m² panel target can be reduced by tinted glass, printing, coatings and bonding layers. Measure luminance and contrast after the final cover is installed.

Touch and Controller Board Options

Touch, HDMI-board and control-board configurations are presented as selectable variants rather than universal standard content. Touch and board variants require separate interface, power and mechanical documentation.

Recommended Applications

The Round Vehicle Instrument TFT LCD Panel is suitable for engineering evaluation in vehicle gauge faces, eBike or scooter dashboards, auxiliary instrument displays, industrial dial interfaces, portable test equipment and circular smart-control panels. Regulated or safety-critical suitability requires completed-system qualification.

Customization and Sample Qualification

A custom Round Vehicle Instrument TFT LCD Panel project may evaluate cover-lens graphics, touch integration, FPC routing, surface treatment, optical bonding, luminance tuning, controller-board matching, branding and packaging. Custom configurations are generally reviewed from 500 pieces; sample and standard-module quantities are confirmed separately.

Procurement Checklist

• Confirm the approved model revision and complete module specification.
• Confirm native 544 × 506 timing and the circular UI mask.
• Obtain the complete 40-pin DPI/RGB pin assignment.
• Confirm FPC pitch, contact side, connector and bend direction.
• Define pixel-data width, clock, sync or data-enable mode and signal polarity.
• Confirm panel, logic and white-LED backlight voltage and current requirements.
• Obtain the validated ST72566 timing or command package for the ordered revision.
• Reconcile 98.36 × 94.37 mm with the 98.88 × 94.12 × 7.80 mm drawing.
• Confirm the 89.76 × 83.49 mm active area and 90.76 × 84.49 mm viewing area.
• Validate 800 cd/m² behind the final cover and bonding stack.
• Confirm touch technology, interface and combined mechanics when touch is required.
• Define temperature, humidity, vibration, sealing and compliance targets.
• Provide sample quantity, annual demand and production schedule.
