Abstract
Official abstract text for this publication.
A method of manufacturing a colorless transparent polyimide film having reinforced glass fabric for flexible displays, suitable for use in increasing optical transmittance of a polyimide substrate having reinforced glass fabric for flexible displays. This method enables the glass fabric and the colorless transparent polyimide film to be matched in refractive index when the glass fabric is reinforced in the colorless transparent polyimide film to enhance thermal and mechanical properties of a substrate for flexible displays, thus satisfying high optical transparency and optical transmittance of 85% or more, required of a substrate for flexible displays, and thereby the colorless transparent polyimide film having reinforced glass fabric can be used as a substrate for flexible displays.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a colorless transparent polyimide film with glass fabric reinforced, comprising: (1) preparing a polyamic acid solution; (2) positioning glass fabric on a substrate, and casting the polyamic acid solution on the glass fabric in a vacuum oven; (3) evaporating a solvent from the cast polyamic acid solution by controlling temperature of the vacuum oven to form a polyamic acid film on the substrate; and (4) subjecting the polyamic…
