A hybrid reflective-emissive display including an electrophoretic medium. The electrophoretic medium includes two types of oppositely-charged, and differently-colored, particles in a fluid. The electrophoretic medium is disposed between a front light-transmissive electrode and a rear electrode including a plurality of apertures, such as a hexagonal grid. The electrophoretic layer is optionally illuminated by a light source disposed on the opposite side of the rear electrode from the electrophoretic medium. A viewer can see either the first or second type of particle at the viewing surface, or one of the particles can be illuminated by the light source, thus emitting light the color of one of the particles.

A display device (30) comprises a reflective display (38) arranged to render a first image viewable through a viewing surface and a projection means (31-37) arranged to render a second image viewable in reflection on the viewing surface, the reflective display (38) and the projection means (31-37) being mounted on a common frame.

An apparatus for displaying a three-dimensional image comprises: a light field generating unit (110), which is configured to receive an incident light beam (112) and generate a three-dimensional light field; and an image revealing medium (120), which is arranged to receive the three-dimensional light field generated by the light field generating unit (110), wherein the image revealing medium (120) comprises a fluid with bubbles or particles suspended in the fluid, wherein the bubbles or particles have a size in the range of 40-500 nm.

Provided is an image presentation system 10, including: a plurality of particle emission units 20 each of which emits particles; an image projection unit 30; and a control unit 50. The control unit 50 controls to cause collision of particles emitted from a first particle emission unit 20 (#1), out of the plurality of particle emission units 20, and particles emitted from a second particle emission unit 20 (#2), out of the plurality of particle emission units, so as to generate a retention field 60 that is used as a screen to which an image is project, and the image projection unit 30 projects an image to the retention field 60.

A water dance device with display screen effect primarily comprises a box body therein are disposed a rotating water spray unit, a swinging water spray unit, a multicolored water spray unit, an intermittent water spray unit, a fogging device, and a laser projector. The rotating water spray unit and the swinging water spray unit are disposed to provide rotating and swinging water jets; the multicolored water spray unit is disposed to provide water jets of various colors; the intermittent water spray unit is disposed to provide single projectile water jets; and the fogging device is disposed to provide a foggy veil for the laser projector to project texts or images thereon. Providing various forms of water dance performance composed in its box body and advertising effect, the present invention may be placed in businesses, stores and shops for achieving the purpose of attracting potential customers.

Content is projected onto on the surface of water such that it can be viewed from either above or below the surface. Using distortion mapping, depth sensing, and de-noising, the image can remain unaffected by ripples and allow the user to interact within the body of liquid and/or use it as input. Liquids of different density can be layered on the surface to create different refraction planes. Water currents and jets can be used to actively reduce ripples from user interaction, as well as actively adding or removing liquid from the container to counteract displacement or create effect.
