Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. The VD6283TX uses hybrid color filters with precise responses allowing accurate computation of the correlated color temperature (CCT) and Lux information that can be used for display brightness management or scene light correction. ST ambient light sensors offer, in optimized packages, photopic or color filters with precise responses that convert ambient light into Lux values with high. Automotive Automotve Grade 2 and 3 qualified devices enables sensing ambient light changes in automotive applications. Thinnest package Industrys thinnest package allows for light sensing integration into the thinest of bezels, and placement behind OLED displays. Light measurement is fast and accurate thanks to an individual ADC and readout circuitry for each color channel (Red, Green, Blue, IR, Clear and Visible). Device-provided >99 human eye spectrum matching ensuring the best user experience. Scheduled for release in 3Q21, the full-color VD6283TX ALS is the smallest 6-channel color sensor the market with 1.83 x 1.0 x 0.55 mm package.
