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 first optically clear adhesive (OCA) and a second OCA. In an implementation, the first OCA includes an acrylic-containing OCA and the second OCA includes a silicon-containing OCA. In some instances, the first OCA can include an additive to filter ultraviolet radiation. In a particular implementation, the first OCA can have a total luminous transmittance of no greater than approximately 30% for at least a portion of the UV spectrum radiation.
