1. A self-healing display stack for use with an electronic reader device, the self-healing display stack comprising:

  • a flexible electrophoretic display (EPD) layer comprising;

    a hot melt protective sheet layer comprising a polymer substrate layer and an optically clear adhesive layer;

    an electrode layer coupled to the hot melt protective sheet layer;

    a microcapsule layer coupled to the electrode layer, wherein the electrode layer is configured to apply a voltage to the microcapsule layer;

    a flexible polyimide thin film transistor (TFT) layer coupled to the microcapsule layer; and

    a back protective sheet coupled to the polyimide TFT layer, the back protective sheet configured to support the EPD layer;

    a first acrylic adhesive layer coupled to the EPD layer;

    a light guide coupled to the first acrylic adhesive layer;

    a second acrylic adhesive layer disposed on the light guide;

    a touch sensor layer coupled to the second acrylic adhesive layer;

    a third acrylic adhesive layer disposed on the touch sensor layer; and

    a self-healing plastic cover lens having a first surface and a second surface, the first surface comprising anti-glare surface features, wherein the self-healing plastic cover lens comprises a synthetic polyurethane polymer, and wherein the third acrylic adhesive layer is in contact with the second surface.
