Improved adhesion layer in flexible coverlens

A flexible coverlens comprising:

• a substrate layer;
• a silicon-containing adhesion layer in contact with a surface on the substrate layer, wherein the silicon-containing adhesion layer includes a silicon-containing adhesion promoter;
• and
• a hardcoat layer over the silicon-containing adhesion layer, wherein the hardcoat layer and the substrate layer are positioned on opposite sides of the silicon-containing adhesion layer, and wherein the adhesion promoter is bonded to the hardcoat layer and the silicon-containing adhesion layer.

A flexible display device comprising:

• a flexible display structure comprising a light source;
• and
• a flexible coverlens positioned on the flexible display structure, wherein the flexible coverlens comprises:
• a glass layer characterized by a thickness of less than or about 50 μm;
• a silicon-containing adhesion layer over a surface of the glass layer;
• and
• a hardcoat layer over the silicon-containing adhesion layer, wherein the hardcoat layer and the glass layer are positioned on opposite sides of the silicon-containing adhesion layer, and wherein a silane-containing adhesion promoter contributes to bonding the hardcoat layer to the silicon-containing adhesion layer.
