STM announces ambient light and color sensing solutions

(Product News, 16 Feb 2007)

STMicroelectronics has announced its light and color-sensing IC intended for a wide range of optical feedback and sensing applications, including mobile phones, notebook PCs, and LCD TVs. The VM6101 is the product in the market to offer both color and ambient light sensing, with an embedded system interface that needs no external components - a cost-saving feature for manufacturers. The VM6101 is ideal for automatic LCD backlight control (Cold Cathode Fluorescent Lamp (CCFL) or white LED).

Single-chip VM6101 measures Yellow, Red, Green, and Blue components and uses industry-standard I²C/SMBus (System Management Bus) for data readout and device setup. Integrated into any system or portable display product, IC enables LCD to be adjusted automatically to match ambient lighting conditions and can also provide color balancing adjustment for projection systems and RGB backlighting. Dynamic range from 30 mLux to 30 KLux is achieved via light-to-frequency pixel architecture.
