An AM-HUD needs to support a wide range of image brightness levels. During a bright sunny day, an image with 10,000 - 15,000 nits may be required. At night or during darkness (e.g. driving through a tunnel), 50 to 100 nits may be adequate. The brightness of an LED-illuminated DLP projection system can be easily adjusted by modulating the LED current intensity. LED current intensity is a software programmable feature in the DLP chipset, and can be changed during operation.
