The so-called “holographic” means that the light on it comes from the light of the external environment in the real world and the light of the display, and the two lights are mixed. Please imagine the blending mode “screen” on PS or AE, or Mihara light. When all colors of light are mixed, only white light is left. (Recall the science fiction movies you have watched before. Are the holographic images in them all shiny?) This is why the reality of Holo is called holographic projection. Like a projector, it projects light.
Add light to realistic scene lighting conditions. As more light is superimposed, the colors become richer and the picture becomes brighter.
The color display technology of HoloLens is the same as that of ordinary projectors, called color sequential projection displays. (You can try to use a 60FPS mobile phone to record the imaging process of the projector, if the projector is poor, you can see the flicker of colors)
The brighter the color of the display, the more likely it is to observe this display-specific phenomenon—
Color-separation is probably because white contains a large amount of RBD three colors. Moreover, when a holographic object is moving quickly, this color separation feels more obvious!
Have you heard of “black” light? No, right? There is no black light in the universe. The darker the place in the universe, the lower the temperature and the less radiation. The lowest temperature is absolute zero. If you want to ask me why your mobile phone and computer display can display “black” now, I will tell you that “black” does not exist. It is just because the screen itself is black, so when the transparency is reduced, you feel it becomes black. . (As the saying goes, why can’t you see your mobile phone clearly in the sun? Why do cinemas have to be completely dark when watching movies?)
There is currently no optical display technology that can display black, or “remove the light from your eyes”…
So if you want to display black with hololens, it can only reduce the transparency. The consequence is that the “blackest” object you see is the most transparent. For this reason, holodesk always looks for a black cloth when demonstrating demos.
