New Backlight Function block Released

Version 1.0 (February 19, 2009)

The Backlight control block is used to automatically limit the backlight intensity to limit temperature build-up inside DP600 series displays.

The backlight intensity is set by the user inside the application. The signal is then routed through the block forlimitation. The block calculates the maximum allowed backlight intensity to prevent unit overheating.

The allowed intensity is based on LCD temperature (AnaIn.LightIn) and ambient light (TemIn.Disp.Temp) sensors. If the display is in direct sunlight only, the backlight intensity is also lowered to prevent rapid heat build-up.
