The expected and tested structure of the effect is that the display content is rendered on a canvas with transparent background which in turn is above a different, dark-colored surface which stands for the display background. The best visuals are achieved when aircraft-internal shadows are rendered via opacity map on the dark surface and the corresponding contrast effects to the transparent canvas. | The expected and tested structure of the effect is that the display content is rendered on a canvas with transparent background which in turn is above a different, dark-colored surface which stands for the display background.

Currently the effect does three major things: | |||
* at low light, it can make overly bright displays look slightly blurry and difficult to read as well as de-saturate the colors. This simulates the effects of a too-bright display on the eye and should prompt the user to dim the display. | |||

* at strong direct light, the effect can extinct the display content if it is set too dim. This should prompt the user to increase display brightness | |||

* finally, if glancing light falls onto the display, the effect can render dust. Note that unlike normal diffuse lighting, the dust appears really strongest when the light almost hits the display from the side. | |||

* in addition to that, the effect contains the same grain map the interior model effect offers. This can be used e.g. to superimpose a pixel raster (to simulate a CRT screen) or to dim the edges of the display as compared to the center as desired. | |||
