Patent number: 8816996Abstract: Provide is a method of driving a barrier panel device. Segment driving voltages are controlled to be applied to a plurality of segments of a first electrode of a barrier panel based on a display direction of an image signal displayed on an image display panel of an apparatus for reproducing a 3D image. An odd barrier driving voltage is controlled to be commonly applied to odd numbered barriers of a plurality of barriers of a second electrode of the barrier panel. An even barrier driving voltage is controlled to be commonly applied to even numbered barriers of the plurality of barriers. The segment driving voltage, the odd barrier driving voltages, and the even barrier driving voltages are synchronized.Type: GrantFiled: June 24, 2009Date of Patent: August 26, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-moo Park, Serguei Chestak, Dae-sik Kim, Kyung-hoon Cha, Seon-deok Hwang

Patent number: 7710648Abstract: A high resolution autostereoscopic display includes: a backlight; a display panel forming an image using the backlight light; a viewing zone separator separating viewing zones of right and left eye images of the display panel; a polarizer polarizing the light from the display panel into first polarized light; a polarization switch converting the first polarized light into second polarized light that is polarized in a different direction; and a birefringent plate including a refractive index that varies consistent with the polarization of incident light. Images corresponding to odd and even numbered column fields are formed with the first and second polarized light, time-sequentially. The birefringent plate shifts the second polarized light with respect to the first. A three-dimensional image with the full resolution of the display panel is formed by images corresponding to an odd-numbered and even-numbered column field with the first and shifted second polarized light, respectively.Type: GrantFiled: February 22, 2007Date of Patent: May 4, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Serguei Chestak, Dae-sik Kim

Publication number: 20060227420Abstract: A stereoscopic display for switching between two-dimensional (2D) and three-dimensional (3D) images. The stereoscopic display includes a display device providing an image and a parallax barrier unit that transmits all incident light in a 2D mode and forms barriers to separate an image for a left eye from an image for a right eye in a 3D mode by moving two facing polarization grating screens relative to each other. The polarization grating screens have a grating pattern such that two kinds of birefringence elements changing the directions of polarization of incident light into different directions are alternately disposed horizontally and vertically, and each row of the birefringence elements is shifted with respect to a previous row by a predetermined horizontal distance.Type: ApplicationFiled: April 4, 2006Publication date: October 12, 2006Inventors: Kyung-hoon Cha, Serguei Chestak, Dae-sik Kim
