Avionics device display dimming system and method

摘要

The present general inventive concept provides a system and method to use alpha blending properties of a graphics processor to dim the display, effectively darkening it with neutral color overlays, beyond the last hardware dimming step.

1. A method of dimming a device display of a device, said method comprising the steps of:
generating a background display of data at a first brightness level on the device display; receiving a request to display the data at a second brightness level that is different than the first brightness level; determining a neutral color overlay opacity value that corresponds with said second brightness level; and combining a neutral color overlay of said opacity value with said background via alpha blending to result in said second brightness level for said display, wherein said opacity value is combined with said background over every pixel of said device display.
