Capacitive touch technology key components PACP and ITO Sensor work closely together

Capacitive touch screen technology, as a mainstream touch solution, relies on two key technologies, PACP (Projected Capacitive) and ITO (Indium Tin Oxide) Sensor.

PACP is a projected capacitive touch technology, through the detection of the sensing electrode on the tiny capacitance change to realize the touch detection. PACP manufacturing process is relatively simple, low cost, and multi-touch and gesture recognition has excellent support, widely used in smart phones, tablet PCs and other consumer electronics products.

Different from PACP, ITO Sensor is based on transparent conductive material ITO made of touch sensing layer. ITO Sensor manufacturing process is relatively complex, but its excellent optical properties make it more suitable for integrated display touch solutions, widely used in industrial control equipment, medical equipment and other industry end products.

Industry insiders pointed out that PACP and ITO Sensor in capacitive touch screen has a close relationship. ITO Sensor provides a touch detection of the required conductive electric field, and PACP technology is the use of these electric field changes to accurately detect the user's touch input. The two complement each other and together form the basis of modern capacitive touch screen technology, providing high sensitivity and accuracy for touch interaction.

PACP and ITO Sensor are reshaping the capacitive touch screen technology landscape. With the continuous development of consumer electronics and industrial control field, capacitive touch technology will be further developed to high sensitivity, low power consumption, low cost direction, these two key components will play a more important role.
