Brand factory 2014 key quadrivalence Mn (Mn (IV)) red phosphor breakthrough technology limited in the past, to NTSC 100% for market wide color gamut TV brings new topics and demand.

A new generation of wide gamut TV is expected to debut in 2014, the brand new aircraft fleet in the factory, brand manufacturers will launch with red phosphor and green phosphor, collocation of wide color gamut TV new blue chip, it will reach 100% NTSC, SRGB also has exceeded 100% of the performance, but the technology is the key breakthrough tetravalent manganese red fluorescent powder.

According to the industry that tetravalent manganese red phosphor used in CCFL lamp, this is the four or five family “phosphorus” afraid of heat, afraid of wet powder and afraid of light the shortcomings of early LED into backlight applications have been used, but in the reliability test card, in recent years improved to LED in the process, three wavelength stacking a color coordinate of unique and excellent performance, and improve the brightness advantage.
