In some implementations, an electronic device includes a display stack to display content. The display stack can include a number of substrates coupled using a liquid optically clear adhesive (LOCA). In some implementations, the LOCA can have a modulus of elasticity of no greater than 80,000 Pa. Additionally, the display stack can be formed using a process that includes applying an external force to the display stack by placing the display stack between two fixtures. In an implementation, the external force can be applied while heating the display stack at a temperature of at least 60&#xb0; C. and cooling the display stack according to a particular cooling rate.

Display stack formed to minimize substrate warping

A side surface of a cover glass of an electronic device may be coated with a curable ink to reduce leakage of light from the side surface. The ink may be deposited on the side surface via a pen comprising a reservoir, a valve, and a nib. The nib may comprise a fiber bundle through which pigment particles may pass. The ink may be precisely deposited via the nib on the side surface without visible ink overflowing to a front surface or a back surface of the cover glass.

Ink coating application system and method

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.
