Single Isolation Structure of High Aperture Ratio for a PMOLED

摘要

We have developed a self-aligned single isolationstructure (SIS) and an asymmetric single isolationstructure with an image reversal photoresist toincrease the aperture ratio in a passive matrixorganic light emitting display (PMOLED). Comparedto the conventional structure, the fabrication processis reduced by about 17% and the aperture ratio isenlarged over 4%.
