    摘要： In one embodiment, a brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The brightness enhancement film is capable of collimating light, and wherein, without the coating, the diffusing film would be capable of spread light passing through the back surface. In another embodiment, the brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The diffusing film has a stress retardation gradient of less than or equal to 50 nm/in, wherein an interval for calculation of the stress retardation gradient is less than 1 inch. The brightness enhancement film is capable of collimating light.

    摘要： In one embodiment, the process for forming a multilayer film comprises disposing a supportive layer adjacent to an imprinting layer to form a multilayer film and imprinting microstructures in the imprinting layer as the multilayer film passes between a heated roller and a compression roller. The multilayer film is free of a removable carrier layer. The supportive layer has a supportive layer glass transition temperature that is greater than or equal to about 15° C. higher than the imprinting layer glass transition temperature and/or the supportive layer has a supportive layer melting temperature that is greater than or equal to about 15° C. higher than an imprinting layer melting temperature. The imprinting temperature is lower than the supportive layer melting temperature.
