Panasonic, a worldwide leader in semiconductor products, is pleased to introduce the PNJ4K01F. Featuring a built-in photodiode and current amplifier circuit, this sensor allows for automatic-control of display luminosity relative to ambient brightness. With a spectral response similar to that of the human eye, it’s possible to design brightness control schemes that are tuned for optimal human sensitivity. This, along with a small-package size and low-power consumption, makes the PNJ4K01F ideal for applications in mobile electronics.
