DNP has developed Multi-Primary color filters (adding Yellow, Cyan to RGB) which enables to enlarge color gamut, mass production for the high quality displaymarket will start in this autumn .Dainippon Printing corporation has developed Multi Primary Color filter which is Yellow, Cyan (bright blue color) in addition to conventional RGB (Red, Green and Blue) in order to dramatically expand the color gamut of Display for LCDTV. We will start mass production from this autumn. The FPD TV market is significantly increasing, especially LCDTV growth is outstanding and it is expected to continue the growth due to the increasing popularity of terrestrial digital broadcasting, BS digital broadcasting as well as popularity of DVD. In terms of LCDTV, the demand of wide panel such as more than 30 inch is increasing and high quality is trended along with popularization of digital high definition TV

The demand of high quality of display is increasing not only for TV application but also for mobile display application. Thanks to terrestrial digital broadcasting for mobile telephone which has already started and due to popularity of the TV broadcasting for personal computer and increasing demand of DVD with personal computer, the demand of high display quality such as reproducibility of real color is increased much larger than before. In the conventional RGB color filter, there was limitation to reproduce real color, especially reproducing yellow and cyan was difficult to reproduce.

Multi Primary Color filter development and features ] We have newly developed color material such as yellow and cyan which is adequate for color filter. With this new color filter, we have succeeded to enlarge gamut significantly and have been able to reproduce the color of yellow, gold and turquoise which was difficult to reproduce by conventional LCD display. The feature is followings:
- We will provide 4 primary color filter which is Red, Green, Blue and Yellow, and 5 primary color filters which is Red, Green, Blue and Yellow and Cyan based on customer request.
- The color filter can be used for TV , PC monitor and mobile display for mobile device such as cellular phone which is applicable for terrestrial digital broadcasting
- In conjunction with adequate backlight, compared with conventional RGB color filter which is 72% gamut against NTSC (note 1), 4 Multi Primary Color panel can enlarge the gamut up to 95% and up to 100% with 5 Multi Primary Color panel against NTSC. This Multi Primary Color filter also enable to increase brightness by 35% (DNP internal comparison).

Revenue target and future expansion plan ] DNP will start mass production of Multi Primary Color filter from this autumn 2006 and expected revenue in 2007 is more than 10 billion Yen. We would produce better purity and higher color reproducibility filter combined with ink jet filter manufacturing technology so that it can reduce the manufacturing cost. This newly developed color filter is exhibited at Genoa Color Technologies Ltd booth in SID (Society for Information Display) in San Francisco in USA from June 6th to 8th.
