Dai Nippon Printing: Color Filters for LCD Displays, Photomasks


Dai Nippon Printing (DNP) was established in 1867 as a printing company. From the 1950s onwards, however, it began to diversify its business, eventually becoming a major figure in a number of industries, including printing, electrical systems, publishing, and education. DNP is one of the most internationally well known of Japan’s outstanding companies. Today, it is also focusing on the manufacturing and sales of electronic devices and displays.

Color Filters for LCD Displays
The LCD display manufacturing industry has been taking dramatic steps in recent years. In particular, demand for color filters for LCD displays has been growing, just as applications diversify. DNP has been making significant capital investments in this field, establishing a delivery system, and working to develop pioneering technology.

Demand for color filters for LCD displays is rapidly increasing throughout the globe to be used in a variety of applications, including LCD televisions, computers, smart phones, and mobile telephones. Color filters are a vital component of LCD displays. A color filter comprises red, green, and blue printed on glass substrates. DNP has six color filter production plants in Japan, and boasts world-class production efficiency and competence.

Large-size Photomasks
Large-size photomasks are vital to TFT array formations, STN electrode patternings, and color filter patterning for LCD displays. They are also used in the manufacturing of thermal heads, line sensors, and linear encoders.

DNP has used the superfine processing technology it has developed in the manufacturing of accurate photomasks for semiconductors as a springboard for the manufacturing of large-size photomasks.

In recent years, DNP has pursued an aggressive M&A policy towards companies specializing in industrial sectors it is involved in, and in doing so has expanded the scale of its operations considerably.

Its recent business activities in the photographic film, photographic printing paper, and publishing and distribution sectors include the establishment, in 2010, of a joint venture with the CHI group, namely a new chain of hybrid bookstores, called honto. honto will be working in a number of diverse business fields, and has been set up in response to the growing popularity of digital books, a market expected to grow considerably in the near future.
