Abstract
A display device includes a shutter layer of liquid-crystal material arranged in cells to shutter input light selectively, a cover layer,on the shutter layer, and a set of phosphors,on the cover layer, corresponding to the cells, to be activated by the input light and provide the display image. To prevent crosstalk the active cell areas,defined by the electrode overlaps are smaller than the corresponding phosphors. This prevents crosstalk between cells even when input light that is not fully collimated is used and also allows space for thicker and/or broader electrodes,leading to the cells, reducing resistance, and for other components such as TFTs.
