3.5-inch CTP | GT911 controller with I2C interface | 5-point capacitive uxtouch panel | 6-pin G+G PCAP
This high-performance touch solution, powered by the GT911 driver chip, delivers a smooth, precise, and reliable touch experience. The GT911 chip's exceptional performance ensures stable panel operation across a wide operating temperature range (-20°C to 70°C) and in harsh environments. Its responsiveness is fast and latency-free, enabling precise recognition of everything from light touches and swipes to complex gestures, significantly improving end-user satisfaction.
The CTPH035B22 excels not only in its touch functionality but also in its efficient connectivity. It utilizes a simple and reliable I²C digital interface for communication. This interface design offers significant advantages: it greatly simplifies system wiring, requiring only a few signal lines, such as SDA (data) and SCL (clock), for high-speed data transmission. It also significantly saves valuable space, making it particularly suitable for compact device designs. Furthermore, the widespread support for the I²C standard significantly reduces system integration complexity, accelerating product development. Its 3.3V operating voltage also allows for seamless integration with modern mainstream microcontroller platforms.
The panel itself utilizes a robust glass-on-glass construction, achieving both thinness and durability. Its high light transmittance of ≥85% ensures a crystal-clear display, while its surface hardness of up to 6H effectively resists daily scratches. The black frame design on the front gives the product a refined appearance. This model features a slightly larger touch panel than the display, allowing it to seamlessly integrate with the user's device. We also support customization of the panel's frame shape, size, and color, as well as customized surface treatments (AF/AG/AR). Whether for industrial control panels, smart home terminals, or portable consumer devices, the CTPH035B22 capacitive touch panel, combined with the powerful touch core of the GT911 and the convenience and efficiency of the I²C interface, is the ideal choice for creating the next generation of intelligent, highly responsive human-machine interfaces.
The TFT LCD display paired with this touch panel offers the same performance as the TFT-H035B22WVIST3C30.
