Abstract:
A display device for generating a three-dimensional image from an image signal, the image signal including depth information, comprising:an array of microlenses having a first pitch in a first direction; and an array of light sources impinging upon the microlens array and having a second pitch in the first direction, the second pitch being variable, the array of light sources comprising: an array of phosphor elements; an electron beam directed to impinge upon individual phosphor elements and to cause the individual phosphor elements to emit light; and a mask intermediate each phosphor element and the microlens array, the mask having an angled slit therein to allow a portion of the light emitted by the phosphor elements to pass therethrough; and wherein the second pitch of the array of light sources varies in response to the depth information of the image signal and is determined from a combination of the location of the electron beam impinging upon the phosphor elements and the angle of the slit.
