Explanation

A digitizer is a transparent input layer placed over a display that detects and converts touch or stylus input into digital signals the computer can process. It is the component specifically responsible for enabling touch functionality. IPS (In-Plane Switching) is a type of LCD panel technology that improves color and viewing angles but has nothing to do with touch. An inverter powers the backlight in older CCFL displays. OLED is a display technology based on organic light-emitting diodes, not a touch-enabling component.
