This is the most common type of touch, and when pressure is applied to the surfaces of two transparent electrodes, the position is recognized by detecting the voltage change that occurs when the two layers come into contact. It has low cost due to mass production, simple structure and detection circuit, and high recognition resolution. However, since two transparent electrodes are used, the transmittance is low and the average lifespan is about 1 million cycles, so it has low durability.
