28‐4: Aftermarket Detection of Line Defects in Display Panels Using New TDDI with Testing Mode

In this paper, we propose a set of tests for detecting line defects in display panels by integrating Touch with Display Driver (TDDI) technology and Gate‐driver‐on‐array (GOA) circuits. Currently, TDDI is widely adopted in displays with integrated touch functionality, serving both display driving and touch sensing purposes. The primary advantage of our approach is the utilization of the TDDI module's self‐diagnostic capabilities, which allow for effective defect detection even after the displays have been installed in high‐value products such as automobiles.
