Abstract
An optic film has a surface on which a plurality of rib-like micro light guides is formed. Each light guide includes a plurality of ridges, which are of different height and shows variation of height. Either a high ridge or a low ridge of the light guide is made a continuous left-and-right wavy configuration and/or a continuous up-and-down height-variation configuration. Thus, light transmitting through the optic film and converged by the light guides leaves the optic film in a form that is not very regular so as to facilitate subsequent use of the light in for example a liquid crystal panel.
Claims5
An optic film having a surface on which a plurality of micro light guides is formed, wherein each of the light guides comprises at least two ridges of different heights whereby the ridges comprise at least one low ridge and at least one high ridge, and a first number of the ridges of the light guides are of both a continuous left-and-right wavy configuration and a continuous up-and-down height-variation configuration, while a second number of the ridges are of a straight linear configuration.
