Abstract
Disclosed are a backplane substrate, which achieves improved interface bonding characteristics via a recess configuration at the interface of an organic layer with an inorganic layer, thereby preventing peeling due to repeated folding, and a flexible display using the same. An organic layer is introduced into a recess provided in an inorganic layer so as to achieve improved interface bonding characteristics.
Claims20
A backplane substrate, comprising:
- a base substrate in which an active area having a plurality of sub-pixels is defined in a center thereof and a dummy pixel portion having dummy pixels is defined along an edge of the active area;
- an organic layer positioned to overlay both the dummy pixels and the sub-pixels;
- and
- an inorganic layer stack in contact with the organic layer at least at the location of the dummy pixels, the inorganic layer stack having a plurality of adhesion recesses, in which the organic layer is present.

A flexible display, comprising:
- a first flexible base substrate in which an active area having a plurality of sub-pixels is defined in a center thereof and a dummy pixel portion having dummy pixels is defined along an edge of the active area;
- a second flexible base substrate configured to be opposite the first flexible base substrate and having a touch wire;
- an adhesive layer provided between the first and second flexible base substrates;
- an organic layer provided on at least one of the first flexible base substrate and the second flexible base substrate so as to correspond to the dummy pixels and the sub-pixels;
- and
- an inorganic layer stack configured to be in contact with the organic layer thereabove over at least the dummy pixels, the inorganic layer stack having a plurality of adhesion recesses, in which the organic layer is present.
