20120032997 | BACKLIGHT UNIT AND 2D AND 3D IMAGE DISPLAY SYSTEM - A backlight unit and a two-dimensional (2D) and three-dimensional (3D) image display system including the same. The backlight unit includes a first light guide plate and a second light guide plate, wherein the first light guide plate includes a plurality of first diffusion units that are aligned to be spaced apart from each other, and the second light guide plate includes a plurality of second diffusion units that are aligned alternately with the first diffusion units. Thus, an emission direction of light is controlled, so that a 3D image may be displayed in a plurality of viewing zones. | 02-09-2012 |
20130222366 | DISPLAY PANEL AND DISPLAY APPARATUS USING BIREFRINGENCE - A display panel and a display apparatus are provided. The display panel includes an image panel having pixel lines; a polarization panel which switches a polarization direction of a ray of light emitted from the image panel; and a lens which passes the ray of light provided from the polarization panel. The lens includes a first lens array which has a first birefringence characteristic, a second lens array which has a second birefringence characteristic different from the first birefringence characteristic, and which is arranged at a location to face the first lens array in an alternating manner, and a liquid crystal portion which has a same birefringence characteristic as either the first birefringence characteristic or the second birefringence characteristic, and which is filled in between the first lens array and the second lens array. | 08-29-2013 |
20130286168 | 3D DISPLAY DEVICE AND METHOD - A 3D display device includes: a data processor configured to generate at least one frame by combining a left-eye image and a right-eye image; a panel including pixels, each of the pixels including three sub pixels; a barrier configured to form a light blocking region and a light transmitting region on the panel on a basis of two sub pixel units; and a controller configured to control the data processor to generate the at least one frame by placing the left-eye image and the right-eye image alternately on the basis of two sub pixels, and to control the panel to display at least one frame generated by the data processor. | 10-31-2013 |
20140192044 | DISPLAY APPARATUS AND DISPLAY METHOD THEREOF - A display apparatus includes a display panel which includes a plurality of sub pixels each outputting a sub pixel value of R, G, or B, a renderer which renders a multi-view image to be outputted by the display, and a controller which determines a rendering pitch according to a viewing distance of a user, and controls the renderer so that each of at least some of the plurality of sub pixels outputs a combined sub pixel value corresponding to a combination of sub pixel values corresponding to each of the plurality of views of the multi-view image according to the determined rendering pitch. | 07-10-2014 |
20140192172 | 3D DISPLAY DEVICE USING BARRIER AND DRIVING METHOD THEREOF - A 3D display apparatus is provided, which includes a display panel which displays a multi-viewpoint image, a barrier arranged on one side of the display panel unit, and a controller which controls the barrier to alternately form light transmitting areas and light blocking areas. The barrier includes a liquid crystal layer, a plurality of upper electrodes arranged to be spaced apart from one another on an upper surface of the liquid crystal layer, and a plurality of lower electrodes arranged to be spaced apart from one another on a lower surface of the liquid crystal layer. | 07-10-2014 |
20140368624 | DISPLAY APPARATUS AND TOUCH PANEL - A display apparatus includes a display panel configured to display an image frame that includes a right-eye image and a left-eye image, and a touch panel configured to sense a user touch, wherein the touch panel includes a polarizing switch panel configured to switch a direction of polarization of light emitted from the display panel, and a parallax realization layer which is formed on one side of the polarizing switch panel and is configured to provide a binocular disparity image by using light emitted from the polarizing switch panel. | 12-18-2014 |
20150042772 | DISPLAY APPARATUS AND CONTROL METHOD FOR PROVIDING A 3D IMAGE - A display apparatus is disclosed. The display apparatus includes an image processor configured to extract a main object from an image frame so as to generate a 2D image frame in a region of the extracted main object in order to generate a 3D image frame in regions other than the main object in the image frame; a display panel configured to alternately output the 2D image frame having a predetermined first resolution and the 3D image frame having a predetermined second resolution; and a controller configured to control a polarization direction of light output from the display panel in synchronization with outputs of the 2D image frame and the 3D image frame. Thus, the display apparatus may provide a high-resolution 3D image and improved depth. | 02-12-2015 |
20150220058 | MOBILE DEVICE CAPABLE OF DISPLAYING HOLOGRAM AND HOLOGRAM DISPLAY METHOD - A mobile device is provided which is capable of displaying a hologram. The mobile device includes a main body including a screen; a light guide member disposed above the screen; an entrance optical member disposed on a surface of the light guide member; and an image hologram disposed on a surface of the light guide member and laterally spaced apart from the entrance optical member. When an area of the screen corresponding to the entrance optical member emits a light, a holographic image stored in the image hologram is displayed above the light guide member. | 08-06-2015 |
