Fujifilm Launches Plasma Display Materials Business Silver Halide Photography Technology Applied to an Electromagnetic Radiation Shielding Film for Plasma Display Panels

May 19, 2005

Fuji Photo Film Co., Ltd. (President and CEO: Shigetaka Komori; hereinafter referred to as "Fujifilm") has developed an electromagnetic radiation shielding film for plasma display panels (hereinafter referred to as PDPs), the demand for which is rapidly increasing. The film is produced using silver halide photography technology. Fujifilm intends to continue developing manufacturing technologies with a view to mass production and to initiate full-scale business operations in 2006.

Flat panel TVs have seen rapid growth in recent years, and plasma TVs are no exception - sales of which are predicted to top 10 million units in 2008, which is over 3 times the present volume.

An electromagnetic radiation shielding film is attached beneath the surface of a PDP to prevent electromagnetic radiation being irradiated from the panel. Fujifilm's new electromagnetic radiation shielding film was made possible through an application of its in-house silver halide technology - a technology garnered through endeavors in fields such as photography, graphic arts and medical imaging. In detail, a fine mesh of silver halides is fabricated on a transparent film, and this provides excellent transmittance, high shielding and improves image quality.

Characteristics of the electromagnetic radiation shielding film developed through the silver halide photography technology:

(1)  The use of highly sensitive silver halides makes it possible to fabricate, by digital exposure, any desired mesh pattern, thus manufacturing can be specifically tailored to meet panel specifications such as size and resolution.
(2) The blackness of the developed silver in the electromagnetic radiation shielding film is advantageous in producing a realistic black color on the display.
(3) The production processes are simpler than those for conventional methods such as Copper Foil Etching, which will lead to future cost reduction and more stable production.
(4) The film can be supplied in roll form, so that further processes can be readily integrated, such as adding an antireflective coating to the surface.

Fujifilm contributes to the flat-panel display market with four strong products with unique characteristics: FUJITAC*1, which is a polarizing plate material indispensable to LCD panels; WV Film*2, which widens viewing angles; CV Film*3, which has strong antireflective effects on panel screens; and Transer*4, a film used to produce color filters. Fujifilm will start full-scale business in PDP materials, which is expected to grow along with LCDs in the flat-panel television related, market, and will further contribute to the uptake of flat-panel displays.

The new electromagnetic radiation shielding film will be displayed at the Society for Information Display 2005 (SID2005), to be held in Boston, U.S., from May 24, 2005.

*1  FUJITAC: Made from cellulose triacetate (TAC) material, FUJITAC has superior optical qualities and is used as a protective film for the polarizing plates used in LCDs.
*2 WV Film: A film that greatly widens the viewing angles of LCD panels. A product unique to Fujifilm.
*3 CV Film: An antireflective film for the surfaces of LCD panels. Its characteristics include low reflectivity, high precision and high resistance to dust and dirt.
*4 Transer: A film used to produce color filters for LCDs. A color LCD panel is created by transferring red, green, blue and black color layers from these films to the glass using dry lamination technique. It is optimal for use in manufacturing large LCD panels.
