DNP has key roles in the digital interface business, featuring optical films for displays* and metal masks for manufacturing organic light-emitting diode (OLED) displays, both of which hold the world’s top market share; and the semiconductor business, which includes photomasks for manufacturing semiconductor products and lead frames for semiconductor packaging materials, as growth-driving businesses.

Segment strengths
･Develop industry-leading products leveraging large area functionalization technology in roll to roll process, micro and nano modeling technology, optical control technology, etc.
･Keep world-leading share in areas such as metal masks for OLED displays and optical films for displays*

*Anti-reflection and anti-glare function applied on the display surface

DNP excels in fine processing technology across various substrates, including metal, glass, and resin, leveraging techniques derived from its expertise in printing technology. Among these, the Electronics segment identifies the following three as core technologies:

- Photolithography
- Coating
- Molding

By utilizing these three technologies, we develop and deliver a variety of products to the world.

This technology forms high-resolution replica by exposing light or electron beams on a photosensitive material on the substrate, thus creating the original image.
It is used in the manufacture of a variety of products that require patterning, such as semiconductor integrated circuits, printed circuit boards, printing plates, and liquid crystal displays.

Wet coating is a process in which inked materials thinly and uniformly cover the surface of a substrate. Combined with substrate design technology, it allows to create coated products having various functionalities.

This technology, using convex/concave-surface metal, glass, and resin molds, has expanded into nanoimprinting, enabling the transfer of convex/concave shapes onto a base material surface. Stemming from printing processes where plates are synchronized with printed patterns, this technology now transfers patterns of 20nm or smaller*, effectively transferring not only optical features but also textures.

*By nanoimprinting with glass molds, not by roll-to-roll

Our core technologies for AR glasses development help manufacturers realize cutting-edge AR glasses that are lightweight, high-performing, and visually immersive. Similarly, our efforts in VR headset development incorporate advanced VR headset technology to enhance user experience and performance.

DNP is constantly developing cutting-edge products not only for digital interface and semiconductors but for the entire electronics industry.
We have been exhibiting for over 10 years at 'SID Display Week,' one of the world's largest trade shows in the display industry, held annually in the United States, where we present our latest products and technologies each year.

DNP's technological prowess enables us to continuously develop indispensable smartphone components. These include miniaturized sensors, efficient heat dissipation, easily viewable displays, core elements in semiconductor manufacturing processes, and lightweight, secure packages for lithium-ion batteries.

With strengths that we have applied and developed from our printing and information (P&I) technologies, we provide products and services which have achieved top global share. We will continue to deliver unique products and value that only we can offer to the world.

DNP has established business sites around the world to provide products and services for the global market.
