1st, top layer is transparent and scratch-proof, it also provides multi-touch capabilities and stylus-recognition.

2nd layer is innovative: it’s kind of like e-paper with a very high resolution (perhaps around a dot size of 100 µm or less), but they’re black or transparent instead of either black or white (possibly, but not necessarily, with intermediate shades), one way of implementation are millions of ultra-thin ultra-black discs each fitted between two transparent half-spheres that can be oriented and remain stable (i.e. the black disc is invisible when it’s vertical).

3rd layer has bigger, faster-switching tri-color elements (RGB) that only work when lit and are otherwise transparent.

4th layer is bright white (even when off) and made of an illuminating (organic) material.

… and of course it’s bendable and can be applied to (“printed on”) any kind of surface.

When reading text only the 2nd layer is used, the 3rd and 4th are off and power for the 2nd is only needed when switching pages, but the 1st, input layer also needs power except when the system is in non-interactive mode. Nevertheless the 4th layer can be activated in selected areas only so that you can have colorful pictures or videos inside crystal sharp text. Alas, for real video applications it’s only well-suited if the 2nd level can achieve a state switch frequency of at least 24–30, better 50–100 Hz.

The order of the 2nd and 3rd layer may be changed. In that case the transparent spheres may be slightly opaque white.

       nice usage sequestering but...
how are you going to have e-paper using black and transparent dots ? What makes e-paper work is you have white dots which hide the black ones... and it's reflective technology not pass-thru. [-]

       I like the idea of a screen with layers that can be switched on and off to conserve power. But I don't think this one would work.

       FlyingToaster, imagine each dot consists of two transparent half-spheres which have an thin opaque black disc between them. The disc is only visible if parallel to the screen surface, if they’re orthogonal towards each other the dot is transparent. In- between angles may result in shades of gray.

       So, in essence an epaper touchscreen overlayed on a regular monitor?
