As the LED industry ushers in the lighting era, the patent layout of the LED factory has entered a new game. Japan's LED manufacturer Nichia has always adopted a proactive strategy in LED patent layout and litigation. As Nichia's key core patents for YAG phosphors will expire in 2017, Nichia is actively deploying new material patents, especially recently attracting industry attention. The quaternary manganese Mn (IV) patent consolidates its patent power status.
It is reported that the quaternary manganese Mn (IV) red phosphor material has been used in CCFL lamps in the past, and has the disadvantages of being afraid of heat, fear of moisture and fear of light. In recent years, it has been improved by large factories, and has the advantage of improving brightness in the LED process. In addition, the unique three-wavelength stacked color coordinates have also performed well in the industry. The quaternary manganese Mn (IV) patent was first held in the hands of the US giant GE, and later including Nichia and SHARP.
According to industry sources, both Japan and SHARP are actively pursuing research and development and application of related patents for tetravalent manganese materials. In particular, Japan and Asia are the most active. Japan and Japan not only carry out physical improvement of quaternary manganese, but also adjust chemical structure. And apply for related patents simultaneously.
With the successful introduction of LED package components using quaternary manganese red phosphor materials into LED backlights, LED manufacturers will be more aware of the development and introduction of this quaternary manganese phosphor material. Therefore, the industry is also eager to stalk Japan. The development of improved research and development and patent layout of quaternary manganese materials.
