THREE-DIMENSIONAL DISPLAY APPARATUSES

An apparatus for a three-dimensional display is disclosed that includes a waveguide having a pair of opposed faces configured to propagate radiation along its length, a radiation source optically coupled to the waveguide, at least one prismatic element having a face optically coupled to a face of the waveguide, and a layer of image modulating material optically coupled to a face of the waveguide.The image modulating material may be optically coupled to an area of a face of the waveguide, at least a portion of the area being located outside a perimeter of a face of the prismatic element. 公开了一种用于三维显示的设备，包括：波导，具有一对相对的面，所述相对的面被配置为沿着波导的长度传播辐射；辐射源，与波导光学地耦合；至少一个棱镜元件，具有与所述波导的一个面光学地耦合的面；以及图像调制材料层，其光学地耦合到波导的一个面。图像调制材料可以光学地耦合到波导的一个面的区域，该区域的至少一部分位于棱镜元件的一个面的周边之外。
