Custom 34-inch touch display module with EMI shielding and full optical bonding for reliable railway control systems.
Home » Railway Touch Display Driver Console

Project Overview

Application: High-speed train driver instrument console
Panel Size: 34 inch TPM (Touch Panel Module)

Core Requirements:
  • Maintain stable touch performance in high electromagnetic interference environments
  • Provide strong electrostatic discharge (ESD) resistance
  • Integrate a shielding structure to reduce signal interference
  • Ensure long-term reliability for railway control systems
  • Adopt full optical bonding for improved display stability and durability

The system must operate reliably in complex electrical environments while maintaining stable touch performance and long lifecycle reliability for railway equipment.

Technical Challenges: Railway Touch Display

The customer identified several key technical concerns during the project:
Electrostatic Discharge Protection

ESD Protection

Railway control systems must comply with strict ESD protection standards to prevent malfunctions caused by electrostatic discharge during operation.
Electromagnetic Interference

EMI

Electrical systems in trains generate significant EMI, which can interfere with touch signals and display stability.​​​​​​​​​​​​​​
Long Lifecycle Reliability

Long Lifecycle Reliability

Railway equipment typically has long deployment cycles, and system upgrades occur approximately every 8 years.
The display module, therefore, requires high durability and stable component supply.
High Integration Requirements

Integration Requirements

The customer required a fully bonded display structure (OCR optical bonding) to improve structural stability and display performance.

Custom Railway Touch Display Solution Design

To meet the reliability and interference resistance requirements of railway control systems, FANNAL developed a custom 34-inch touch panel module (TPM) optimized for high-speed train driver consoles.
  • Reinforced Cover Glass


    The display module uses a 3 mm reinforced cover glass to enhance structural integrity and long-term durability.

    Thicker cover glass helps protect the display module from mechanical stress, vibration, and impact that may occur in transportation equipment. The reinforced structure also improves overall system robustness and helps maintain stable operation over long deployment cycles.
  • Anti-UV Surface Treatment

    To improve long-term durability, the cover glass includes UV-resistant ink printing and additional UV protection treatment.

    Railway equipment may experience continuous light exposure over long operating periods. The anti-UV design helps prevent discoloration, material aging, and degradation of printed areas, ensuring stable appearance and performance over time.
  • EMI Shielded Touch Panel

    The touch panel structure integrates an EMI shielding layer to reduce the impact of electromagnetic interference from surrounding electrical systems.

    Railway control environments often contain high levels of electrical noise generated by onboard equipment. The shielding design helps maintain stable capacitive sensing performance and reduces the risk of touch signal disturbance.
  • Industrial Touch Controller


    The touch system is driven by the ILI2323 touch controller, which provides strong noise immunity and stable multi-touch performance.

    This industrial-grade controller helps ensure reliable touch operation in environments where electromagnetic interference and electrical noise may affect standard capacitive touch systems.
  • Industrial LCD Panel

    The display module integrates original LCD panels sourced from established panel manufacturers, ensuring stable display quality and long-term supply availability.

    Using original panels helps maintain consistent brightness, color performance, and reliability across production batches, which is important for railway equipment with extended lifecycle requirements.
    ​​​​​​​
  • OCR Full Optical Bonding

    The display module adopts OCR full optical bonding between the cover glass and LCD panel.

    Optical bonding enhances display clarity by minimizing internal reflections while significantly strengthening the module's structural integrity against vibration and environmental stress, making it an ideal choice for demanding transportation and industrial control applications.

Reliable Touch Display for Railway Console Systems

The final solution delivers a high-reliability 34-inch touch display module designed for the demanding electrical environment of railway control systems.
By integrating reinforced cover glass, EMI shielding within the touch panel structure, and an industrial-grade touch controller, the system effectively improves resistance to electromagnetic interference and electrostatic discharge, ensuring stable touch interaction in the train driver console.

Full OCR optical bonding further enhances the structural stability of the display module while improving optical clarity and long-term durability.

As a result, the display module provides:
  • Improved ESD and EMI resistance for complex onboard electrical environments
  • Enhanced structural durability for long deployment cycles
  • Stable capacitive touch performance in railway control systems
  • Reliable operation aligned with the 8-year equipment upgrade cycle

The solution is now integrated into high-speed train driver console systems, supporting stable and reliable operation of railway control equipment.
