P‐228: <i>Late‐News Poster:</i> An Advanced Flexible OLED Anti‐ESD Design

As OLED screens gain increasing recognition in the market, they have become the standard for mainstream high‐end products. However, the OLED process is complex, involving numerous steps, and is prone to ESD issues, which negatively impact product yield and pose challenges to OLED production. To improve the anti‐ESD ability of the screen process, the mechanism of ESD occurrence is analyzed, and product design is optimized to enhance the anti‐ESD ability. Three main approaches are implemented: first, adjusting the ESD circuit design to optimize the electrostatic discharge channel; second, optimizing the structure design of TFT devices to improve their anti‐ESD capability; and third, applying an organic film layer to the screen to block electrostatic intrusion. These optimizations successfully reduce the ESD incidence rate from 7.5% to 0.1%.
