Low power colour sensor for display applications
Highly sensitive, this digital RGB colour sensor features a four channel digital output for sensing red, green, and blue (RGB) via an I²C interface. CCT and Lux sensing work through the master control unit (MCU). Using an RGB algorithm, infrared light noise is effectively avoided to calculate CCT and Lux figures accurately. Even in a less bright environment, it still can reach high sensor resolution of 0.002 lx per count.
The CLS-16D17-34-DF6 can be used in display equipment including smart watch, mobile phone, tablets and notebooks, navigation systems, virtual keyboards and sensor for Internet Of Things (IoT). Thanks to RGB colour sensing, the brightness and colour temperature of a backlight can be adjusted based on the ambient light source, which makes the display applications more comfortable for human eyes.
Other features include: programmable exposure time; convert incident light intensity to digital data; 16-bit CS ADC resolution; automatic light flickering cancellation supporting; excellent transmittance of glass package; spectral response close to human eye; linear CS response for easy design; low dark noise and a low stop current of typical 1 µA.
