真彩色色度计BriEye--上海喜安电子科技有限公司

产品的溯源和背景:

BriEye脱模于Philips公司，对于LCD屏幕的测量，集合FPDM（国际平板显示测量标准），并整合PHILIPS 近10年的色度学研发形成的高速，快捷，准确的测量原则，特别适合在线测量和对于LCD的Trimming.

PHILIPS公司早期的研发团队在上海CTC和荷兰的总部双方联合开发，对于越来要求越高的LCD品质要求，在速度和、准确性以及价格的三个方面的特点，历时4年的开发，形成成熟的产品,先后在MOTOROLA和NOKIA的相关产品上使用。

由于PHILIPS的LCD业务在大陆的消退，该业务转让给奇美（富士康），以后在Iphone等手机屏幕上在线调试和应用。

产品特点:

高速传输，数据率达到10K的吞吐率。

准确度高，色度误差0.1%，亮度误差4% 基本上可以替代拓普康和美能达的相关产品

测量范围广可以测量0.01cd/m²到10Kcd/m²
