3M and Sony in optical film licensing pact

SAN FRANCISCO (Reuters) - 3M Co (MMM.N) and Sony Corp (6758.T) have agreed to a licensing deal that gives Sony the right to use certain 3M optical film technologies for use in LCD television products, the companies said on Friday.

In a joint statement, the companies said the licensing deal covers prismatic films for use in making liquid-crystal display panels.

Optical films are used to make electronic displays brighter than displays without enhancement films, which results in energy savings for devices using them.
