Types of Touch Screen Panel Film Dot Spacer Glass Glass Resistive circuit layer Electrode Electrode Resistive Type Capacitive Type Touch Screen Panel A touchscreen panel (TSP) detects the precise coordinates of a user's touch on a display. Once contact is made, it pinpoints the location and relays the data to the device's control system, triggering the corresponding function. Touch technologies are broadly divided into resistive and capacitive systems. Early smartphones relied on resistive panels, which register input through applied pressure. Today, capacitive touchscreens dominate. They sense changes in electrical capacitance when a finger contacts the surface. With higher sensitivity and native multi-touch support, capacitive technology has become the standard across modern mobile devices.
Touch Screen Panel Structure Touch Screen Panel Polarizer Polarizer Glass Glass + Touch Screen Panel Panel Panel Glass Glass Add On Type On Cell Type Touchscreen panels are categorized by structure into add-on and on-cell designs. Add-on (external) types place the touch sensor on top of the display panel. This approach simplifies manufacturing but increases overall thickness and weight. On-cell (integrated) types embed the touch sensor within the display panel. This improves light transmittance and enables thinner, lighter designs, making it the preferred solution in modern devices.
