Abstract: In some examples, a lighting apparatus includes a light guiding component having a light absorbing material disposed on at least one surface. The light absorbing material may be selected to have light absorbing properties to compensate for variations in the color of portions of light emitted by a light source. For instance, the color of the light absorbing material may be generally complimentary to an undesirable color of a portion of the emitted light. Consequently, by reflecting the portion of light off the light absorbing material, the undesirable color may be absorbed from the portion of the light so that the resulting light is of a more uniform color. This disclosure also describes techniques for assembling electronic devices in a component stack to provide enhanced display lighting uniformity.

Abstract: Described herein are electronic devices that includes a display stack having a cover component atop a lightguide component and a display component below the lightguide component. In some instances, the cover component including an antiglare etching applied to a top surface of a coverglass and a touch pattern applied to a bottom surface of the coverglass. In some cases, an optically clear adhesive layer formed from two types of optically clear adhesive may be located between the cover component and the lightguide component and a ring adhesive may be applied to around an outer edge of the cover component, the optically clear adhesive and the lightguide component.
