Abstract
In this work, we propose active stylus application using selfcapacitive
touch with OLED TDDI. Active stylus application using
self‐capacitive touch sensor has several benefits in comparison to
using mutual‐capacitive touch sensor, such as “Smaller RC
Loading in Active Stylus Sensing”, “Uplink Signal Partially
Driving”, and “Downlink Signal Through Palm Removing”. With
these benefits, active stylus application can get better writing
experience and accuracy using self‐capacitive on OLED On‐Cell
product. Finally, we propose the word wide first OLED TDDI
(Touch and Display Driver Integration) NT38770 passed Wacom
LV1 certification with 6.67” OLED module.
