LED supplier Arima Optoelectronics Corp. of Taoyuan, Taiwan, announced yesterday that "quite a few" major LED makers may have infringed its patent (no. 171221) concerning the process to create a mixture of phosphor and scattering optical media. The patent claims that a scattering optical media with a bandgap larger than 3 eV can improve the color quality of white LEDs. "Arima Opto will take serious consideration and action to protect its intellectual property and vigorously enforce its intellectual property rights," said Senior Manager Yung Hui Chuang in a statement.
