| Abstract | A method of the invention for forming a pixel-defining layer on an OLED panel is disclosed. The method of the invention for forming a pixel-defining layer on an OLED panel, comprising following Steps: (A) providing a Substrate; (B) forming a plurality of first electrodes in parallel Stripes on said Substrate, (C) coating a layer of non-photosensitive polyimide or polyimide precursor compositions on Said Substrate; (D) first prebaking Said Substrate; (E) coating a layer of photoresist compositions on Said layer of non photosensitive polyimide or polyimide precursor composi tions, (F) Second prebaking said Substrate; (G) forming patterns of Said photoresist by exposing Said Substrate to masked radiation and developing said photoresist; (H) etch ing Said layer of Said non-photosensitive polyimide or polyimide precursor compositions to form patterned poly imide or polyimide precursor compositions, (I) releasing or Stripping Said patterned layer of Said photoresist composi tions; and (J) baking said Substrate with patterned non photosensitive polyimide or polyimide precursor composi tions to form Said pixel-defining layer. |
