35‐1: The Mechanism and Solution of Horizontal Line Defects by Mutual Interference of Flexible OLED and Touch Sensor

The high voltage driving in touch sensor of flexible OLED has been employed for improving the performance of touch sensor. However, the high voltage ingenerates visible horizontal line defects in specific modes. The mechanisms and solutions of horizontal line interference are explained and proposed...

Zusammenfassung:The high voltage driving in touch sensor of flexible OLED has been employed for improving the performance of touch sensor. However, the high voltage ingenerates visible horizontal line defects in specific modes. The mechanisms and solutions of horizontal line interference are explained and proposed by tuning the timing and frequency of touch signals.
