When using high brightness displays, in many cases the display won’t be solely exposed to day light environment, but also to darker environment so that automatically dimming of the backlight will be necessary.
On the other
hand, many field experiences have shown that ambient light dimming curves needs to get adapted, in some cases even for each single application.
Due to this requirement EVERVISION has developed an adaptive Ambient Light Sensor which allows the user to define his own dimming curve by an utility tool.
The sensor itself covers the human eye wavelength range of ~ 400
– 780nm and has got a wide dynamic range of 0,01 – 83000 Lux. Moreover the sensor also comes with wide input operation voltage range of 3.3 - 24.0V. Output signal is 3.3V PWM at a range of 0 – 100%.
