The present invention provides a hard coating film having high hardness and excellent properties. The hard coating film has high hardness and is not easily curled.

Hard coating film

A method of preparing a hard coating film by applying a first hard coating composition onto one side of a supporting substrate, performing a first photocuring by irradiating one side of the supporting substrate, applying a second hard coating composition onto the other side of the supporting substrate, performing a second photocuring by irradiating the other side of the supporting substrate which the second coating composition applied on, with ultraviolet having a first wavelength and a second wavelength longer than the first wavelength.

Method of preparing hard coating film

Disclosed is a plastic film exhibiting excellent physical properties including a high level of hardness, high scratch resistance, and low reflection. Exhibiting a high level of hardness, scratch resistance, impact resistance, low reflectivity, and high transparency, the plastic film can be used as a substitute for a cover plate made of glass or reinforced glass.

An optical element is provided. The optical element is a light-dividing element, for example an element that can divide incident light into at least two kinds of light having different polarized states. The optical element can be used to realize a stereoscopic image.

Optical element

Provided are a frequency modulation/demodulation apparatus using a frequency selective baseband and a transmitting/receiving apparatus using the same. In a frequency selective baseband transmission technique or an FS-CDMA technique, a transmission rate is controlled according to communication channel environment, spread code groups are repeatedly selected in a receiving side so as to obtain a frequency diversity gain. Accordingly, it is possible to reduce interference between users. In addition, even in a case where strong interference induced from electronic exists, it is possible to implement low-power, stable human-body communication and to ensure a communication quality.

A method and apparatus for communicating a sound wave is provided. The apparatus includes: a sound wave converter converting a sound wave signal transmitted from a counter apparatus through the human body into an electrical signal when the sound wave is transmitted from the counter apparatus through the human body and converting an electrical signal on data to be output to the counter apparatus into a sound wave; a data processor receiving the converted electrical signal from the sound wave converter and transmitting an electrical signal on the data to be output to the sound wave converter when the data to be output exists; and a switch connected between the sound wave converter and the data processor, the switch transmitting the converted electrical signal to the data processor and transmitting the electrical signal on the data to be output to the sound wave converter. Accordingly, it is possible to efficiently transmit a signal with a low loss of sound wave signal. Thus, it is possible to simply construct communication hardware at a low price.
