●LCD Color Filters
Making energy-efficient, high brightness LCDs a reality.
In order to improve brightness in LC color filters, DNP developed a dye-based color resist that has greater heat resistance than conventional pigment-based products, and improved the transparency of the blue resist, which has less brightness than other color resists. By pairing the color filter with the right backlight, it becomes possible not only to widen the color reproduction gamut, but also to conserve electricity by reducing the number of LEDs used in the product. DNP will continue research and development aimed at commercializing not only the processing technologies involved but also the materials technologies. In addition, we will work to develop color filters that are optimized for combination with optical films that can further expand the color gamut, and offer these as a new solution for high-definition (HD) smartphones and ultra HD (4K and 8K) televisions.
Advanced optical films make possible the rich expression of information.
In 1990, DNP used the coating technologies that it had cultivated through its printing operations to start developing low reflection films. DNP went on to capture the top share of the world market for anti-reflection films. Previously, developers of these types of films found that when they increased the anti-reflective properties, the film’s hardness decreased and it became more susceptible to scratching and soiling. DNP approached its product development from a fresh angle and in 2014 succeeded in developing ultra-low reflection film that is both highly soil-resistant and significantly reduces glare from indoor light, making it possible to produce a display that exhibits images with vivid contrast. Thanks to DNP’s know-how and technical prowess, we were able to fulfill two competing needs, i.e. to achieve desirable degrees of both reflectance, which is the key to clearly visible images, and of hardness, which protects against scratches.
●Image Display System
Image display system for use with ultra-short focus projectors, its screen eliminates exterior light and, images on the screen are clearly visible even in a well-lit room.
DNP has begun sales of its display system for ultra-short focus projectors, which makes it possible to hold teleconferences that so closely imitate face-to-face meetings that participants can read the expressions on each other’s faces. Because the system’s screen eliminates superfluous exterior light and reflects to viewers only light from the projector, images on the screen are clearly visible even in a well-lit room, unlike previous projector screens. Despite the system’s large size, it consumes little electricity. Compared to a similarly sized liquid crystal display, it is lighter, thinner, easier to handle, and offers outstanding cost performance. DNP will continue to enrich people’s lives by combining the new display system with our strengths in data processing and content production. Beginning with digital signage, other applications that we will explore include remote medical care and educational services for children.
