Liyitec provides various options for a PCAP solution, suitable for different applications and environments. All have the same basic design: X axis on the top conductive layer and Y axis on the bottom conductive layer, and a node is formed in each intersection, to detect the change of the capacitance in the electronic loop. During operation, the controller supplies current to each conductive layer and forms an electric field among all the channels and nodes. After a finger or a certain conductor moves close to the field, the controller wastes no time detecting the change of the capacitance and reports the touch point by precise calculation. Due to the 3-dimensional electric field, the panel can still function by a proximate finger or stylus rather than necessarily a real touch. In other words, it implies the PCAP is Z axis detectable.
