On-cell Touch Screen, Built for Wearable Interaction
E1473AC63.B integrates an on-cell touch sensor directly on the AMOLED stack, reducing extra layers compared with add-on touch panels. This helps keep the module thin and lightweight, while improving optical clarity for small UI elements—icons look cleaner and text edges stay crisp because there’s less gap and fewer interfaces for reflection.
Touch data is handled through the built-in ZTW622 touch IC, communicating to the host via I2C, with dedicated TP_INT and TP_RST signals for stable event reporting and reliable recovery. For smartwatch and wearable controls, this on-cell architecture supports responsive taps and swipes while simplifying system design: you get a compact display + touch solution without needing an additional external touch module or extra bonding steps.
