Abstract
A display system () for capturing a finger print () includes a display panel () with pixels regularly arranged at an average pitch P1. The display system () includes a multilayer optical film () including microlayers () disposed between a structured first major surface () and a second major surface (). The structured first major surface () includes a plurality of structures () having an average largest lateral dimension d, d<P1 or d≥2P1. The structures () are regularly arranged at an average pitch P2 of greater than about 40 microns and have an average maximum height h of about 1.5 microns. For a normally incident light and a visible wavelength range and an infrared wavelength range, and each of orthogonal first and second in-plane polarization states, the microlayers () reflect greater than 60% of the incident light in the visible wavelength range, and transmits greater than 30% of the incident light for at least a first infrared wavelength.
