Existing technologies allow to discard the screen and the massive body of a phone. There is only a case-frame, the emptiness inside becomes the virtual screen and the control tool of the device. Tiny lights, the beams of which being crossed in space form shining points, are placed along the internal contour of the frame. Thus, the image is weaved out of light streams, just like fabric.
Device control process: each ray crossing point has concrete coordinates and an external feedback. Once the light contact is broken, appears a signal with the interruption coordinate.
