|---|---|
| Ambient Gentle | Will increase display screen darkness |
| Display Dimension | Bigger screens require extra gentle |
| Display Distance | Larger distance requires greater gentle depth |
| Projection Know-how | Newer applied sciences emit greater brightness |
| Distinction | Greater distinction enhances perceived brightness |
| Eye Adaptation | Dilated pupils improve gentle sensitivity |
| Lumens | Greater lumens point out brighter projection |
| Display Acquire | Greater acquire displays extra gentle, growing brightness |
