1. An electronic device comprising;
- one or more processors;
memory, coupled to the one or more processors and storing at least one content item;
a reflective display configured to display the content item and comprising a top surface;
a capacitive touch sensor coupled at least in part to the top surface of the reflective display and configured to receive touch input, the capacitive touch sensor including a top surface;
a lightguide coupled at least in part to the top surface of the capacitive touch sensor and configured to receive light from a light source at an edge of the lightguide and propagate the light onto the top surface of the reflective display, the lightguide including, a substrate, a layer of lacquer applied to the substrate, and grating elements formed in the layer of lacquer; and
an antiglare component coupled at least in part to a top surface of the lightguide.

Abstract
Electronic devices that include reflective displays for rendering content, touch sensors layered atop the reflective displays for detecting touch inputs, front lights layered atop the touch sensors for lighting the reflective displays and antiglare components for reducing glare caused by ambient light. This disclosure also describes techniques for assembling electronic devices including these component stacks.

24. A method for assembling at least a portion of an electronic device that includes a touch sensor coupled to a top surface of a reflective display, the method comprising:
-
coupling a front light to a top surface of the touch sensor, the front light configured to propagate light from a light source onto the reflective display; coupling an antiglare component onto a top surface of the front light; and coupling light-diffusive reflective tape residing around at least a portion of a perimeter of the antiglare component, the light-diffusive reflective tape configured to reflect light from a light source onto the reflective display. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
