Abstract:
A display device is provided. The display device includes a plurality of diffractive optical elements each configured to emit light guided in a light guide plate to a user. Virtual images by the light are observed by the user at two or more different depths according to the plurality diffractive elements.
Abstract:
A three-dimensional (3D) image rendering method and an apparatus are provided. The 3D image rendering method includes determining optical images associated with candidate viewpoint positions in a viewing zone, determining virtual rays intersecting a pixel of a display panel based on the determined optical images, and assigning a pixel value to the pixel based on respective distances between intersection points between the rays and an optical layer and optical elements of the optical layer.
Abstract:
A backlight unit includes first light guide plates (LGPs) provided in a line shape, and second LGPs provided in a line shape and disposed between the first LGPs. The backlight unit may include a controller configured to control a plurality of light sources to provide a light to the first LGPs when a three-dimensional (3D) image is displayed on a display panel that receives the light from at least one of the first LGPs and the second LGPs, and to provide the light to the first LGPs and the second LGPs when a two-dimensional (2D) image is displayed on the display panel.
Abstract:
A display device includes a backlight unit. The backlight unit may include a first light guide plate (LGP) comprising a first optical material and a second optical material. The first LGP is configured to emit light guided through the second optical material toward a display panel using the first optical material. The backlight unit may include a second LGP disposed between the first LGP and the display panel. The second LGP is configured to emit light toward the display panel using a diffuser plate provided in a lower portion of the second LGP. The backlight unit may include light sources configured to provide, under control of a controller, light to the first LGP if a three-dimensional (3D) image is displayed on the display panel, and to provide light to the second LGP if a two-dimensional (2D) image is displayed on the display panel.
Abstract:
Provided is an imaging device including a sensing array including a plurality of sensing elements, an imaging lens array including a plurality of imaging optical lenses, each of the plurality of imaging optical lenses having a non-circular cross-section perpendicular to an optical axis, and configured to transmit light received from an outside of the imaging device, and a condensing lens array including a plurality of condensing lenses disposed between the imaging lens array and the sensing array, and configured to transmit the light passing through the imaging lens array to the sensing elements, wherein a number of the plurality of imaging optical lenses is less than a number of the plurality of condensing lenses.
Abstract:
Disclosed are an optical layer and a display device including the same. The optical layer includes optical components slanted a predetermined angle θ with respect to a pixel included in a display panel, and disposed at an interval of a predetermined distance l, and the predetermined angle θ and the predetermined distance l satisfy l=2g×tan(VAL/2) and a=l/(2g×tan(VAP/2)).
Abstract:
An electrowetting device which includes a polarizable liquid; and a nonpolar solution separated from the polarizable liquid by an interface. The polarizable liquid may include a polar solvent, an organic acid, and ammonium hydroxide having at least one alkyl group.
