Abstract

A polarizing film assembly includes a polarizing film, a speaker film, a vibration improving layer, and a line member. The polarizing film includes a polarizer layer transmitting a vibrating component of light in parallel with an axis of polarization. The speaker film is disposed on the polarizing film to change an electric signal into a mechanical vibration to generate a sound. The vibration improving layer is interposed between the polarizing film and the speaker film to improve the mechanical vibration of the speaker film. The line member is electrically connected to the speaker film to transmit the electric signal. Therefore, display is small-sized, lightweight and improved in sound quality.

Description

technical field [0001] The present invention relates to a polarizing film assembly, a method of manufacturing the polarizing film assembly and a display device with the polarizing film assembly. More particularly, the present invention relates to a polarizing film assembly capable of improving sound quality, a method of manufacturing the polarizing film assembly, and a display device having the same. Background technique [0002] In general, display devices include cathode ray tube ("CRT") display devices, plasma display panel ("PDP") display devices, liquid crystal display ("LCD") devices, organic light emitting display ("OLED") devices, and the like. LCD devices have various characteristics such as light structure, small size, thin thickness, etc., and have been widely used in various fields such as mobile communication devices, monitors, televisions, and the like. [0003] The display device includes a sound unit such as an electromagnetic speaker. The electromagnetic s...
