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.

Abstract: Techniques for providing visual feedback on a display of an electronic device by sequentially and/or independently controlling the illumination of the lighting output by the display. In some implementations, the techniques may be employed following an interaction with the device having one or more light source controllers instructing one or more light sources, such as Light Emitting Diodes (LEDs), in a lighting apparatus, such as for a display which renders content on the device. For instance, a lightguide of the lighting apparatus may sequentially receive light from the one or more light sources as directed by the one or more light source controllers and may direct the light to provide illumination for a display. In some cases, the display may be a reflective display that is front-lit by the lighting apparatus. In other cases, the display may be a backlit display that is backlit by the lighting apparatus.

Abstract: A front light component for electronic devices that include displays for rendering content using a light guide to control illumination for a front light display. A high reflectivity “white” tape is used under and adjacent to the light guide to improve overall uniformity of the light beams. The high reflectivity tape may also be selected to be of a controlled white hue to compensate for variances in color of Light Emitting Diodes (LEDs) where the LED color is slightly off from ideal white. In this way the complementary color of the high reflectivity tape with the color of the LED will cause the output spectrum to be uniform and white. This disclosure also describes techniques for assembling electronic devices in a component stack to provide enhanced display uniformity and improved reading experience.
