Three dimensional displays

A display, comprising:

• an n-layered optical stack defining a plurality of n-layered three-dimensional (3D) columns, wherein each i-th layer of each particular n-layered 3D column includes a group of at least one illuminable element uniquely positioned within each particular n-layered 3D column, wherein each of the at least one illuminable element includes a luminescence material including at least one of a phosphor, a phosphor blend, a rare earth phosphor, or a photoluminescent metal sulfide;
• an optical controller including a plurality of two-dimensional (2D) macro-pixels, each particular macro-pixel uniquely corresponds to a particular n-layered 3D column of the n-layered optical stack and is configured to control a depth of illumination within the particular n-layered 3D column, wherein each particular macro-pixel includes n-number of control groups, and wherein each i-th control group of each particular macro-pixel includes at least one individual pixel uniquely positioned to selectively provide at least one directional beam toward the group of at least one illuminable element positioned in the i-th layer of the particular n-layered 3D column that uniquely corresponds to the particular macro-pixel, thereby allowing each particular macro-pixel to control the depth of illumination within the particular n-layered 3D column that uniquely corresponds to the particular macro-pixel by selectively engaging at least one of the n-number of control groups of that particular macro-pixel;
• and
• at least one filter configured to filter at least one of:
• a light entering the n-layered optical stack and a light exiting the n-layered optical stack.

A method, comprising:

• providing an n-layered three-dimensional (3D) column, wherein each i-th layer of the n-layered 3D column includes a group of at least one illuminable element uniquely positioned within the n-layered 3D column, wherein each of the at least one illuminable element includes a luminescence material including at least one of a phosphor, a phosphor blend, a rare earth phosphor, or a photoluminescent metal sulfide;
• providing a mapping between a two-dimensional (2D) macro-pixel and the n-layered 3D column, wherein the macro-pixel includes n-number of control groups, and wherein each i-th control group of the n-number of control groups includes at least one individual pixel uniquely positioned to selectively provide at least one directional beam toward the group of at least one illuminable element positioned in the i-th layer of the n-layered 3D column;
• and
• facilitating control of a depth of illumination within the n-layered 3D column by selectively engaging at least one of the n-number of control groups of the macro-pixel.
