Front-lit displays and indicators having uniform brightness

A display stack comprising:

• an electrophoretic display (EPD);
• a light guide configured to receive light from one or more light emitting diodes (LEDs), wherein the light guide comprises a first set of surface features disposed at a non-horizontal angled orientation along a first side portion and a second side portion of the light guide, and a second set of surface features disposed at a horizontal orientation along a middle portion of the light guide, wherein the horizontal orientation is horizontal relative to a bottom or top surface of the light guide;
• and
• a cover lens assembly comprising:
• a cover glass layer;
• an anti-glare film coupled to the cover glass layer;
• and
• a hot melt adhesive disposed about lateral edge surfaces of the cover glass layer and the anti-glare film, such that the hot melt adhesive forms a perimeter of the cover lens assembly, wherein the hot melt adhesive is a dark color configured to prevent light leakage about the lateral edge surfaces of the display stack.

A device comprising:

• a housing;
• and
• a display stack coupled to the housing, the display stack comprising:
• an electrophoretic display (EPD);
• a light guide, wherein the light guide comprises a first set of surface features disposed at a non-horizontal angled orientation along a first side portion and a second side portion of the light guide, and a second set of surface features disposed at a horizontal orientation along a middle portion of the light guide, wherein the horizontal orientation is horizontal relative to a bottom or top surface of the light guide;
• and
• a cover lens assembly comprising:
• a cover glass layer;
• an anti-glare film coupled to the cover glass layer;
• and
• a hot melt adhesive disposed about lateral edge surfaces of the cover glass layer and the anti-glare film, such that the hot melt adhesive forms a perimeter of the cover lens assembly, wherein the hot melt adhesive is a dark color configured to prevent light leakage about the lateral edge surfaces of the display stack.
