Through a process of trial and error, the Company narrowed down the list of suitable materials from a wide range of candidates, eventually choosing zinc. In developing its green pigments for color filters, DIC defied conventional wisdom by exploring the use of a different central material with the goal of further enhancing performance characteristics. With the question of how best to realize both high brightness and vivid colors on ongoing challenge for display manufacturers, DIC has responded by developing innovative pigments for this application.Ĭopper has traditionally been the central material used in green pigments. Increasing brightness requires making color filters thinner and more transparent, but this alone will not deliver vivid colors and resolution. This is because reduced light requirements results in longer battery life. The small LCDs used in smartphones and other devices must be clear, easy to read and bright enough to ensure legibility even with less light. Large-screen LCD televisions are expected to deliver superbly realistic and accurate color reproduction. DIC’s passion and development prowess are also evident in its pigments for color filters. Over subsequent years, the Company amassed development and design capabilities, as well as production technologies, crucial to the manufacture of fine chemicals and in 1973 commercialized revolutionary high-performance, long-lasting nematic LCs, which were adopted by Sharp Corporation for use in the world’s first pocket calculator incorporating an LCD. Having positioned pigments for color filters as a business that it expects to drive growth, DIC continues working to reinforce its development and product supply capabilities.ĭIC Response Applying technologies amassed through the production of printing inks to the development and expansion of functional pigments that have become the de facto standard worldwideĭIC first succeeded in developing offset printing inks in-house in 1915 and 10 years later began production of organic pigments for its own use. In addition to improving picture quality, these pigments reduce energy consumption and, by extension, lower emissions of CO₂. The optical properties of pigments in this series have earned high marks from smartphone manufacturers and boosted DIC’s share of the global market for blue pigments to approximately 50%.ĭIC’s pigments for color filters, which satisfy the diverse performance requirements of displays used in LCD televisions, smartphones, tablets and notebook computers while at the same time adding value, have been adopted for use by many color filter manufacturers. In 2012, the Company developed the A series, which boasts a superb balance between brightness and contrast. DIC also manufactures blue pigments for color filters. DIC currently enjoys an 85%- plus share of the global market for green pigments for color filters, making its products the de facto standard. In fiscal year 2014, DIC developed the G59 series of green pigments for wide color gamut color filters, which deliver superior brightness and color reproduction, making them suitable for use in filters for next-generation high-definition displays, including those for ultra-high-definition (UHD) televisions. The series includes FASTOGEN GREEN A350, a green pigment characterized by outstanding brightness and contrast that ensures excellent picture quality even with little light from the backlight. With Japan’s shift to digital terrestrial television driving up demand for flatpanel LCD televisions and the popularity of smartphones increasing, in 2007 DIC launched the G58 series of green pigments, which achieved a remarkable increase in brightness. As a consequence, the pigments used in the color filter are crucial to picture quality. LCDs produce images by transmitting light emitted from a backlight lamp through a color filter to which an RGB pattern has been applied. Value Creation Global market-leading pigments that deliver outstanding brightness and picture qualityĬolor images on liquid crystal displays (LCDs) used in LCD televisions, computers and smartphones are produced using the three primary colors of light-red (R), green (G) and blue (B).
