Abstract:
Display devices that include: an organic light emitting diode panel having a multilayer construction including one or more adhesive films; and a polymeric film incorporated within the multilayer construction of the organic light emitting diode panel. The polymeric film includes: a first polymeric layer having two major surfaces, wherein the first polymeric layer includes: a first polymer region including a first material having a refractive index of n1; a second region including a network of interconnected pores and channels within the first polymer region; wherein the pores and channels comprise a second material having a refractive index of n2; wherein n1 is different than n2; wherein the first material includes a first elastic polymeric material and optional particles; and wherein the second material includes: a second polymeric material and optional particles; and/or air; and wherein the polymeric film has: a clarity of at least 90%; a visible light transmission of at least 80%; and a bulk haze of 25% to 80%.
