Patent Application Titled "Method of Displaying Three Dimensional Image and Three Dimensional Display Apparatus for Performing the Method" Published Online

By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors HAMAGISHI, Goro (Hwaseong-si, KR); ODAKE, Ryota (Hwaseong-si, KR); YU, Seong-Jun (Suwon-si, KR); JEON, Sang-Min (Yongin-si, KR), filed on April 15, 2013, was made available online on February 6, 2014.

The assignee for this patent application is Samsung Display Co., Ltd.

Reporters obtained the following quote from the background information supplied by the inventors: "Exemplary embodiments of the present invention relate to a method of displaying a three-dimensional ('3D') image and a 3D display apparatus for performing the method. More particularly, exemplary embodiments of the present invention relate to a method of displaying a 3D image for increasing a display quality of a 3D image and a 3D display apparatus for performing the above-mentioned method.

"Generally, a liquid crystal display ('LCD') displays a two-dimensional ('2D') image. Recently, 3D displays using an LCD have been developed since demands for the 3D image have been increased in various industrial fields such as game and movie industries.

"Generally, the 3D image display apparatus displays the 3D image using the principle of binocular parallax through two eyes of a human. For example, since the eyes of a human are spaced apart from each other, the eyes provide two different images to the brain. This is the process by which a brain exploits the parallax due to the different views from the eye to gain depth perception and estimate distances to objects. Thus, the observer may watch the 3D image to recognize the stereoscopic image through the display apparatus.

"Typically, the stereoscopic image display apparatus is classified into a stereoscopic type, which requires viewer to wear glasses to perceive the 3D images and an auto-stereoscopic type, which does not require the viewer glasses. The stereoscopic type may include a passive polarized glasses method with a polarized filter having a different polarized axis according to two eyes, and an active shutter glasses method. In the active shutter glasses method, a left-eye frame image and a right-eye frame image are time-divided to be periodically displayed, and a pair of glasses which sequentially open or close a left-eye shutter and a right-eye shutter respectively synchronized with the periods are used.

"Recently, the stereoscopic image display apparatus includes a shutter panel which transmits and blocks light emitting from the back-light unit, a lenticular lens which changes the light through the shutter panel into a directional light and a liquid crystal panel which sequentially displays a left-eye image and a right-eye image during a frame."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "These and other needs are addressed by the present invention, in which exemplary embodiments of the present invention provide a method of displaying a 3D image capable of displaying a 3D image according to an observer's position.

"Exemplary embodiments of the present invention also provide a display apparatus for performing the method of displaying the 3D image.

"Exemplary embodiments of the invention disclose a method of displaying a three-dimensional ('3D') image. The method includes designating shutter electrodes of a unit part as a left-eye electrode or a right-eye electrode. The unit part includes 'n' shutter electrodes (herein, n is a natural number). The method also includes selectively driving the left-eye electrode and the right-eye electrode as an opening part, to transmit light through the opening part, based on an image to be displayed on the display panel. The method includes providing light transmitted through the opening part to an observer via a lens plate unit, the lens plate unit comprising a plurality of lenses.

"Exemplary embodiments of the invention disclose a three-dimensional ('3D') display apparatus. The display apparatus includes a display panel configured to display a right-eye image and a left-eye image. The display apparatus also includes a shutter panel including a unit part which includes a plurality of shutter electrodes. The unit part is configured to operate as an opening part transmitting a light and as a blocking part blocking the light. The display apparatus includes a lens plate including a plurality of lenses arranged in a direction and providing the light transmitted through the opening part with an observer's right-eye and left-eye. The display apparatus includes a control part to determine the shutter electrodes of the unit part as a right-eye electrode and a left-eye electrode. The display apparatus includes a shutter driving part selectively to drive the right-eye electrode and the left-eye electrode as the opening part based on an image displayed on the display panel.

"Exemplary embodiments of the invention disclose a display. The display includes a processor of a control part configured to designate shutter electrodes based on an information of an observer's position. The designation includes a portion of n shutter electrodes being determined as a right-eye electrode and the other portion of the n shutter electrodes being determined as a left-eye electrode. The processor is configured to selectively control the left-eye electrode and the right-eye electrode associated with opening and to selectively incident on the observer's right eye or left eye based on the determined shutter electrodes.

"It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
