Philips Daylight Windows
Well, this is something incredible do look at, cause it´s a little difficult to understand, or at least it is to me.
My limited mind has difficulty to understand this “digital image window shade”, because to me, image displays is based on controlling the amount of emitted energy or light to produce images, so I can´t tell how this works, how can they control the amount of light, or even the color of the light which is coming through the window digitally.
That´ll be something to study in the next months at least.
