Projected Capacitive Touch

Projected Capacitive Touch (PCT) technology is used in touchscreen devices like smartphones and tablets to detect touch input. It works by creating an electrostatic field across the screen’s surface using a grid of transparent electrodes. When a finger touches the screen, it changes the electrical field at that point, allowing the device to recognize the touch location. PCT is highly sensitive, supports multi-touch (multiple fingers at once), and is durable, making it ideal for devices requiring responsive interaction. This technology is commonly used due to its precision and ability to function well even through protective glass.
