4.3-inch PCAP | Suitable for TFT LCD displays | GT911 controller - I2C interface
This touch panel, designed specifically for 4.3-inch TFT LCDs, leverages its core advantages to become an ideal companion for high-definition display applications. Its integrated GT911 driver chip is the cornerstone of an exceptional touch experience. This chip not only ensures stable and reliable operation across a wide operating temperature range (-20°C to 70°C) and in harsh environments (≤90% RH), but also provides high sensitivity and precise touch positioning, delivering a smooth, responsive, and durable user experience. Its interface utilizes the I2C protocol, offering significant advantages. Requiring 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 design greatly simplifies connection to the host control system, optimizes PCB layout space, and reduces system complexity and wiring costs, making it particularly suitable for integration into compact 4.3-inch devices.
Critically, the panel boasts exceptional optical performance, with a light transmittance exceeding 85%. Such high light transmittance means that the loss of light emitted by the TFT LCD display's backlight source as it penetrates the touch layer is significantly reduced, preserving the original image's brightness, color saturation, and contrast to the greatest extent possible. This directly translates into an improved visual experience for end users—images presented on the display are brighter and more vivid, details are sharper, and colors are more realistic and saturated, fully unleashing the high-definition image quality potential of the 4.3-inch TFT LCD. Combining the stable and high-performance touch control provided by the GT911 chip, the simple and efficient connection of the I2C interface, and the top-notch display quality guaranteed by high light transmittance, this touch panel is undoubtedly the best partner for 4.3-inch TFT LCD displays that pursue a high-quality visual and interactive experience.
