Abstract
The invention relates to a method for making an electronic display device (1) having a screen (3) covered by a protection plate, and to a substrate (2) covered by said screen for obtaining such a device. The method comprises the following steps: a) applying glue (10) at the non cross-linked state substantially on the entire surface of the screen and/or the assembling surface (11a) of the plate (11) following a deposit on the screen connection area (5) of at least one organic layer (15) for protecting the connection area from the glue; applying the assembling surface against the screen via the glue; c) emitting a radiation through the plate for cross-linking the glue; and d) removing a portion of the plate covering the connection area so that the latter can be electrically accessible, the protection layer being removed from the connection area upon said removal or during a further surface processing step. According to the invention, the protection layer contains at least one organic compound selected from the group comprising compounds derived from diamines and organometallic complexes with heterocycles.
