Abstract

The present invention provides a method for producing a flexible organic electro-luminescent faceplate and a display module thereof. The invented production method comprises: (a) preparing a rigid planar carrier plate; (b) forming a plastic substrate on the carrier plate and jointly forming a pre-determined thickness; (c) depositing at least a protective layer on the plastic substrate; (d) preparing an organic electro-luminescent device array on the protective layer; (e) providing a flexible cover and comprehensively attaching a double-face-adhesive non-solidification film between the plastic substrate and the flexible cover; and (f) peeling off the carrier plate. Thus, the pre-determined thickness is equivalent to the thickness of a glass substrate produced by a conventional process. As a result, the above-mentioned steps can be carried out in a platform without altering conventional process parameters.
