Abstract: Articles and methods of making light redirecting film constructions including a micro structured optical film bonded in selected areas to another film, and including a diffuser are described. The diffuser has an optical haze in the range of (20) to (85) percent and an optical clarity of no greater than (50) percent. The diffuser may be a surface diffuser and may be an asymmetric surface diffuser.

Abstract: Hybrid signage capable of self illumination and having an active backlight. The signage includes a turning film having a structured surface for redirecting light in order to passively illuminate a printed graphic or shaped sign when the backlight is off. In the shaped sign, the shape provides the content, such as letters, to be conveyed to the viewer instead of a graphic. The signage can be actively illuminated when the backlight is on to supplemental the passive illumination.

Abstract translation: 混合标志能够自我照明并具有主动背光。 标牌包括具有用于重定向光的结构化表面的转向膜，以便当背光关闭时被动地照亮印刷图形或成形标志。 在形状符号中，形状提供了要传达给观看者而不是图形的内容，例如字母。 当背光打开时，标志可以被主动照亮以补充被动照明。

Abstract: Self illuminated back and front lit shaped and two-sided signage. The signage includes a turning film having a structured surface for redirecting light and a diffuser providing for diffusion. The shape of the signage from a viewer's perspective provides the content, such as letters, to be conveyed to the viewer. Two-sided signage includes two signs arranged back-to-back, each including a turning film having a structured surface for redirecting light, a diffuser providing for diffusion, and a printed graphic. In the two-sided signage, the turning films receive light from an ambient light source and direct the light via the structured surfaces toward viewers of the two graphics in order to passively illuminate the signage. The two-sided signage can be shaped to provide content via the shape and graphics.

Abstract translation: 自身照亮背部和前面照亮形状和双面标牌。 标牌包括具有用于重定向光的结构化表面的转向膜和用于扩散的扩散器。 从观众的角度看，标牌的形状提供了要传达给观众的内容，比如字母。 双面标牌包括背对背布置的两个标志，每个包括具有用于重定向光的结构化表面的转向膜，用于扩散的扩散器和印刷图形。 在双面标牌中，转动胶片从环境光源接收光，并将光通过结构化表面引导到两个图形的观看者，以被动地照亮标牌。 双面标牌可以通过形状和图形形状提供内容。
