P‐77: Research on the Causes of OLED White Spot Defects and Exploration of Improvement Directions

With the development of OLED display technology and the intensification of competition in the OLED mobile phone product market, consumers have increasingly high requirements for the display quality of OLED mobile phones. Higher product quality and yield requirements encourage panel manufacturers to enhance their competitiveness through equipment improvement, process improvement, and product design optimization. Poor white spots are an important factor affecting display quality. This article studies the mechanism of white spot defects and provides an effective direction for improving particles, optimizing equipment, and optimizing process parameters to reduce the impact of white spot defects.
