FAQ

Designed for rigorous industrial, medical, and automotive environments, this 6.8-inch capacitive touch panel features a robust Glass-on-Glass (G+G) structure. Powered by the high-performance Microchip mXT640U controller, it delivers exceptional precision, multi-touch capabilities, and superior EMI immunity, making it the ideal choice for outdoor terminals, handheld devices, and industrial control systems.

Key Features:

Superior Durability (G+G Structure): The Glass+Glass construction ensures high transparency, chemical resistance, and long-term stability. The chemical-strengthened cover glass offers surface hardness ≥7H, protecting against scratches and impact in harsh work settings.
Industrial-Leading Touch IC (mXT640U): Equipped with the Microchip maXTouch® 640U controller, supporting up to 5-10 point precision touch with an ultra-fast response time and high signal-to-noise ratio (SNR).
Adaptable Touch Modes:
- Glove Touch: Supports operation with various industrial gloves (up to 5mm thickness).
- Waterproof/Wet Touch: Advanced algorithms prevent false touches from water droplets or mist, ensuring reliability in outdoor or humid environments.
- Stylus Support: Compatible with passive pens for high-precision input.
Sunlight Readable & Optical Bonding Ready: Optimized for high-brightness displays (up to 1000 nits compatibility). We offer professional optical bonding services to minimize reflections and enhance contrast for outdoor use.
EMI/EMC Excellence: Built to pass rigorous industrial EMI standards, ensuring the touch performance remains unaffected by high-frequency noise from motors or wireless modules.
Long Lifecycle Support: Specifically designed for industrial B2B projects with a guaranteed 5-7 year supply lifecycle to ensure your product's stability.

FAQ

Q1: What is the benefit of the G+G structure for my industrial application?

A: G+G (Cover Glass + Sensor Glass) offers the best optical clarity and environmental resistance. Unlike G+F (Film) structures, it won't warp or yellow over time when exposed to heat or UV, making it perfect for long-term industrial deployments.

Q2: Does this 6.8-inch touch screen support operation with medical or industrial gloves?

A: Yes. Our firmware is tuned to support a wide range of materials, including latex, nitrile, and thick industrial work gloves. We can further customize the sensitivity based on your specific glove requirements.

Q3: Can I use this touch screen in an outdoor environment with rain?

A: Absolutely. The mXT640U controller includes "Water Suppression" features. It can distinguish between a finger touch and a water spill, preventing "ghost touches" and maintaining functional control even when the surface is wet.

Q4: Is it possible to customize the Cover Lens (shape, color, logo)?

A: Yes, Fannal specializes in full customization. We can adjust the cover glass thickness (up to 6mm or more), add IK-rated impact resistance, print custom logos, or apply surface treatments like Anti-Glare (AG), Anti-Reflection (AR), or Anti-Fingerprint (AF).

Q5: What interface does it use, and is it "Plug-and-Play"?

A: It uses a standard I2C (IIC) interface. While I2C requires driver integration on your host CPU (Linux/Android/Windows), we provide complete technical support and driver code to ensure a smooth integration process.

Q6: What is the MOQ (Minimum Order Quantity) for this product?

A: For our standard 6.8" module, we offer flexible MOQ to support your prototyping and small-batch production phases. Please contact our sales team for a specific quote based on your project volume.
