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.

Display stack

Technologies are described herein for photobleaching a display. A display may be photobleached by exposing the display to light emitted by an external lamp and/or may be photobleached using one or more display lights of the electronic device during a burn-in period. In some examples, the light emitted by the lamp is filtered to remove wavelengths below a certain wavelength. The light that is received by the display from the lamp may include wavelengths between about 310 nm and 700 nm. These wavelengths correspond to visible light and near-visible light. The display may be exposed to the light for some duration or until some dose of light is received by the display. In other configurations, a burn-in period is performed for about eighteen hours.
