The 6.8 Inch Capacitive Touch Panel (Model: CTP-H068A04-V1-0) is a high-performance interactive solution designed specifically for slim-profile smart devices and industrial controllers. Featuring a unique uXTouch large cover design, the external glass dimensions (195.39 x 73.5 mm) are intentionally larger than the active viewport, allowing for a seamless, edge-to-edge finish when integrated into your housing. Built on a rugged G+G (Glass-on-Glass) structure, this panel provides an exceptional screen-to-body ratio, eliminating unsightly bezel gaps while offering a 6H surface hardness that protects against daily wear and industrial stress.

🔩 Installation & Maintenance Guide
How to Install This 6.8 Inch Capacitive Touch Panel
-
Alignment Use the "uXTouch" large cover to align the panel with your device housing. Ensure the viewport (60.79 x 161.112 mm) is centered over the LCD.
-
FPC Connection Gently insert the 6-pin FPC into the ZIF connector on your mainboard. Ensure the gold fingers are facing the correct direction and the latch is securely locked.
-
Bonding For the best visual result, use Optical Bonding (OCR/OCA) to eliminate the air gap between the touch panel and the TFT display.
Maintenance & Care of This 6.8 Inch Capacitive Touch Panel
-
🧹Cleaning: Use a soft, lint-free cloth. For stubborn grease, a small amount of 70% isopropyl alcohol is safe for the G+G surface.
-
⚠️Handling: Avoid sharp bends in the FPC cable (minimum bend radius of 3mm) to prevent internal trace damage.
-
📦Storage: Store in a dry environment (≤90% RH) to maintain the integrity of the bonding adhesives.

❓ Frequently Asked Questions (FAQ)
💬 What does the "uXTouch large cover" design mean for my device integration?
The uXTouch large cover means the outer glass dimensions (195.39 x 73.5 mm) extend beyond the active touch viewport (60.79 x 161.112 mm). This allows the panel to overlap your device housing frame, creating a seamless, bezel-free "floating display" appearance without visible gaps or edges.
💬 What is the difference between G+G and G+F touch panel structures?
G+G (Glass-on-Glass) uses two layers of tempered glass for both the sensor and cover, offering superior optical clarity, higher surface hardness (6H), and resistance to warping or the "rainbow effect." G+F (Glass-on-Film) uses a glass cover with a film sensor, which is thinner but less durable and optically inferior for demanding applications.
💬 Is the GT911 driver chip compatible with common operating systems and microcontrollers?
Yes. The GT911 is an industry-standard capacitive touch controller widely supported by Linux (via the goodix driver), Android, and various RTOS platforms. It communicates via the I2C interface (SCL, SDA, INT, RST), making it straightforward to integrate with popular MCUs such as STM32, ESP32, and Raspberry Pi CM modules.
💬 Can the surface coating be customized — for example, with Anti-Glare or Anti-Fingerprint treatment?
Yes. HOTHMI offers optional surface coating customization including AG (Anti-Glare), AR (Anti-Reflection), and AF (Anti-Fingerprint) treatments. These can be applied based on your specific deployment environment, whether it is an outdoor industrial panel or a premium consumer device.
💬 What TFT display module is recommended to pair with this capacitive touch panel?
This 6.8 Inch Capacitive Touch Panel is designed to pair perfectly with the TFT-H068A04ZAINV8N40 display module. Together, they form a full HD, sunlight-readable interactive module optimized for both embedded and industrial applications.
💬 Does HOTHMI support custom silk-screen printing and cable length modifications?
Yes. HOTHMI provides factory-direct customization services including custom silk-screen logos and branding on the cover glass, as well as modifications to FPC cable lengths and connector configurations. Please contact the HOTHMI sales team with your project specifications for a tailored quotation.
