Coffee Machine Interface

4.3″ UART module with printed cover glass and appliance-control integration.

Illustrative case layouts. Images, project quantities, specifications, and outcomes are examples awaiting verified customer project information.

Project Background

Application: Coffee Machine Interface. Illustrative annual demand: 12,000 units. The project brief called for a 4.3″ TFT solution supporting MCU / UART.

Customer-Specific Requirements

Operating environment: Kitchen lighting; moisture exposure
Display: 4.3″ TFT
Resolution: 480 × 272
Brightness: 400 nits target
Temperature: 0°C to +60°C target
Grade / qualification: Appliance requirements
Host / interface: MCU / UART

The Challenge

Fit a compact appliance fascia while maintaining clear visual feedback and practical touch operation.

Display Selection Considerations

We compared module outline, power needs, viewing angle, and UART control requirements.

What Was Adapted

We adapted cover-glass printing, outline, and front-panel mounting to the appliance.

Display & Touch Driver Integration

We aligned MCU communication, command validation, display states, and appliance-control feedback.

Validation & Production Handover

Review image output and display timing, relevant touch or communication behavior, mechanical fit, and the approved configuration before pilot production. Project-specific results and qualification records should be added to the final case study.
