Abstract
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° C. and cooling the display stack according to a particular cooling rate.
