P‐182: Eliminate Circular Bright Spots Resulting from Poor Compatibility between PI and Liquid Crystal in LCD

Poor compatibility between PI (polyimide liquid crystal alignment agent) and liquid crystal in LCD can lead to poor liquid crystal alignment and deflection performance, as well as the appearance of bright spots, resulting in a decrease in panel yield. This article analyzes the formation mechanism of these bright spots. Finally, we address this issue by designing a PI structure.

Abstract

Poor compatibility between PI (polyimide liquid crystal alignment agent) and liquid crystal in LCD can lead to poor liquid crystal alignment and deflection performance, as well as the appearance of bright spots, resulting in a decrease in panel yield. This article analyzes the formation mechanism of these bright spots. Finally, we address this issue by designing a PI structure.
