Abstract:
A display including an electrowetting prism array is provided. The display includes: a light source, a 2-dimensional (2D) display for providing an image using light from the light source, a prism array in which a refractive power of one or more prisms of the prism array is adjustablein real time, and an optical element which increases a refraction of light transmitted therethrough. In the display, the optical element may be disposed in front of or behind the prism array. The optical element may be a convex lens, a Fresnel lens, a holographic optical element (HOE), a diffraction optical element (DOE), or a second electrowetting prism array. The convex lens may be a variable focus lens.
Abstract:
Provided are an electrowetting prism device which has increased an aperture ratio by simplifying an electrode and wiring structure, and a 3D image display apparatus capable of providing a super multi-view 3D image using the electrowetting prism device. The electrowetting prism device includes lower and upper transparent substrates disposed against each other, a vertical wall mounted on the lower transparent substrate so as to form a diamond-shaped space, a first electrode arranged along two adjacent sidewalls of the vertical wall, a second electrode arranged along the other remaining two adjacent sidewalls of the vertical wall to be disposed against the first electrode, and a non-polarized liquid and a polarized liquid arranged within a space surrounded by the vertical wall.
Abstract:
Provided is a micro-lens capable of changing a focal length. The micro-lens includes a plurality of electrodes, and an electrowetting liquid layer that is separable from the electrodes and that has a focal length that is controlled by a voltage applied to the electrodes.
Abstract:
Provided is a technology for controlling an electrowetting cell. The electrowetting cell may be controlled by applying a preset first voltage to the electrowetting cell, measuring a first circuit parameter between any one side surface and a conductive liquid disposed in the electrowetting cell and determining whether a reset second voltage is to be applied to the electrowetting cell based on the measured first circuit parameter.
Abstract:
Provided are an integral imaging type 3-dimensional (3D) image display apparatus and a 3D image pickup apparatus for increasing a depth by using an electrowetting lens array. The 3D image display apparatus includes a display panel and an electrowetting lens array having an electrically adjustable variable focal distance. The 3D image display apparatus displays a plurality of images having different depths on different focal planes and thus a depth of a 3D image by using one display panel.
