TEXTURED FILM AND PROCESS FOR MANUFACTURE

摘要

A textured film, a process for manufacture of the textured film, and a light management stack, a backlight, and a display using the textured film are described. The textured film and process for manufacture thereof, include processes in which the surface texture of the optical film is controlled by incorporation of a patterned coating. The surface texture of a polymeric film, such as a polymeric optical film, is controlled by incorporation of the coating, that can fracture or deform upon stretching the film.

主权项

1. A textured film, comprising:
a strain-hardened polymer film having a first major surface; a first polymer layer disposed on the first major surface; and a second polymer layer disposed on the first polymer layer, the second polymer layer comprising a plurality of protruding regions, each of the protruding regions having a protruding thickness greater than a coated thickness adjacent the protruding regions, wherein a portion of a first thickness of the first polymer layer adhered to each of the protruding regions is greater than a second thickness of the first polymer layer between at least one adjacent protruding region.
