Multi-Touch Operation and System Reliability

Operators of mission-critical equipment often need to wear gloves or use a stylus to enter commands. The equipment may also be used when water is present on the screen or in environments with electromagnetic interference. AMT RMT products use pressure-based sensing and can operate reliably under high electrical noise or wet conditions. They also support various input methods, offering more intuitive operation while maintaining the reliability of resistive touch.

• Gesture Support: Includes tap, tap and hold, rotate, and zoom gestures for map browsing, image viewing, and equipment parameter adjustment.
• Operation in Wet Conditions: Continues to operate when water is present on the touch surface, making it suitable for outdoor equipment and other devices that may be exposed to moisture.
• Reduced Electromagnetic Interference: With a mesh film, the system offers improved EMI performance and meets MIL-STD-461E RE102 requirements.
• ESD Protection: Meets the requirements for 15 kV air discharge and 8 kV contact discharge, improving equipment stability when exposed to electrostatic discharge.

RMT Value-Added Services

In addition to stable touch performance, outdoor and mobile equipment must withstand long-term sunlight exposure, surface scratches, reflections from ambient light, and external impacts. To address these conditions, AMT RMT products can be paired with various value-added touch panel structures and integration services to further improve the durability and readability of RMT touch displays.

• Glass-Film-Glass (GFG) Design: Uses glass as the touch surface for better scratch resistance, making it suitable for equipment that is used frequently or for long periods.
• Low-Reflective (LR) Design: LR and GFG LR structures reduce reflections from ambient light and improve screen visibility outdoors and in bright environments.
• Anti-UV Design: GFG or GFG LR products can include an anti-UV design that meets the requirements of the 1,000-hour MIL-STD-810H Pro 1 test, reducing the effects of ultraviolet light on materials.
• Optical Bonding Service: Eliminates the air gap between the touch panel and display, reduces reflectance and parallax, and improves overall structural strength.

PenMount RMT Controllers

AMT RMT solutions use PenMount touch controllers developed in-house. Each RMT controller supports a different range of RMT touch panel sizes. This broad size support allows RMT products to be used in handheld devices, in-vehicle displays, industrial HMIs, and applications that are not suitable for projected capacitive touch solutions.

• PM6601 Control Board: Supports 7” to 13.3” RMT touch panels.
• PM6602 Control Board: Supports 13.3” to 21.5” RMT touch panels.
• Multiple Interfaces: Supports USB, I²C, UART, and RS-232 for easy integration into different hardware systems.
• System Platforms: Supports Windows and Linux operating systems to meet common system development needs.
• Flexible Integration: The controller IC can be integrated into the COF tail or directly into the customer’s mainboard.

By integrating AMT RMT touch panels, PenMount RMT touch controllers, firmware, drivers, and optical bonding services, AMT helps customers build reliable resistive touch display systems that support multi-touch operation.
