A BRIGHTNESS_NIT_RANGE structure contains a linear range of supported millinit levels.
Syntax
typedef struct _BRIGHTNESS_NIT_RANGE {
ULONG MinLevelInMillinit;
ULONG MaxLevelInMillinit;
ULONG StepSizeInMillinit;
} BRIGHTNESS_NIT_RANGE, *PBRIGHTNESS_NIT_RANGE;
Members
MinLevelInMillinit
Lowest level in this range. Calibrated data provided to the display driver by OEMs should be taken with an On Pixel Ratio (OPR) percentage of 100% where each pixel is set to an RGB value of (255, 255, 255) or floating point equivalent.
MaxLevelInMillinit
Highest level in this range. Can be equal to MinimumLevelInMillinit to represent a range with just one level. For example, this could support a display with just one boost level. Calibrated data provided to the display driver by OEMs should be taken with an On Pixel Ratio (OPR) percentage of 100% where each pixel is set to an RGB value of (255, 255, 255) or floating point equivalent.
StepSizeInMillinit
The size of steps between valid brightness levels in the range. Minimum + StepSize * n is considered a valid level for non-negative n, where the level is equal to or below maximum. (Maximum – Minimum) % StepSize should always be zero. If MinLevelInMillinit == MaxLevelInMillinit, then this should be zero.
