  • Publication number: 20080048156
    Abstract: Disclosed is a functional film composition for a display which comprises an engineering plastic resin, a first pigment absorbing a near-infrared ray; and a second pigment selectively absorbing a wavelength and maintaining thermal stability at a temperature of about 200 through 300° C., thereby exhibiting an excellent electromagnetic wave shielding function in a range of 550 to 610 nm which emits orange light in addition to in a range of 900 to 1200 nm of a near infrared ray, exhibiting a relatively good thermal resistance, moisture resistance, and light resistance in comparison with a conventional transparent plastic film, and exhibiting superior color purity and brightness, so that it can be applied to a PDP filter pursuing good quality, cost reduction, composition of each function, and simplification of structure, and particularly applied to display devices, such as an LCD, an OLED, a flexible display, and the like, pursuing improved optical properties.
