ABSTRACT:
A television screen is provided with one or more substrates made of a thin film. A number of materials may be used for the film substrate. Further, structures are formed on one or more resin bearing surfaces of the film substrates using a number of techniques, including using patterned rollers to press against the resin bearing film surfaces. The resin can be liquid resin that is cured to set the patterned structures. The thin film results in stronger yet lightweight televisions screens that are safe and easy to handle.
