Claims3
A foldable OLED polyimide backplane fabrication process comprising:
- a. roll-to-roll film web process, and
- b. panel-by-panel conveyer process,
- wherein the roll-to-roll film web process guides a polyimide precursor PAA solution casting into a web, stretching into a quarter wave retarder and drying into a roll of polyamic acid film;
- wherein the panel-by-panel process allows the polyamic acid film to laminate onto a polyimide precursor coated glass panel, to post-cure into a polyimide film on a hot-plate station and proceed to carry out an AMOLED production;
- wherein the polyimide film is finally peeled off from the glass panel;
- whereby the foldable OLED polyimide backplane fabrication process turns out a predetermined foldable display panel.
