8.0-inch Capacitive Touch Panel  for TFT LCD Displays | GT911 Controller - I2C Interface

Designed for 8-inch TFT LCDs, this touch panel is an ideal companion for high-definition display applications, thanks to its core strengths. At its heart is the GT911 driver chip, which forms the foundation of an exceptional touch experience. This chip not only ensures stable and reliable performance across a wide operating temperature range (-20℃ to 70℃) and under demanding environmental conditions (≤90% RH), but also delivers high sensitivity and precise touch positioning—resulting in smooth, responsive, and durable interaction.

In terms of connectivity, the panel adopts the I2C protocol, which offers notable advantages: with only two key signal lines—SCL (clock) and SDA (data)—along with power and ground, it enables efficient and streamlined data transmission. This highly integrated interface greatly simplifies connections to the main control system, optimizes PCB layout space, reduces system complexity and wiring costs, and is particularly well-suited for integration into compact 4.3-inch devices.

Crucially, the panel excels in optical performance, boasting a light transmittance of over 85%. This high level of transparency significantly reduces the loss of backlight as it passes through the touch layer, preserving the original screen’s brightness, color saturation, and contrast to the greatest extent. This translates directly into an enhanced visual experience for end-users—images appear brighter and more vivid, with sharper details and richer, truer colors, fully unleashing the HD potential of the 8-inch TFT LCD.

Combining the stable, high-performance touch enabled by the GT911 chip, the simple and efficient I2C interface, and the superior display quality ensured by high light transmittance, this touch panel stands as the perfect partner for 8-inch TFT LCD displays that demand high-quality visual and interactive experiences.
