Patent number: 8885018Abstract: A display comprises a parallax optic (2), such as a combined parallax barrier and lens array, and a pixellated display device (1). The pixels of the display device (1) are arranged as groups cooperating with a parallax element (4) of the parallax optic (2). Each group comprises a first pixel (A) aligned with the centre of the parallax element (4), second and third pixels (B, C) on either side of the first pixel (A), and fourth pixels (D) shared with adjacent groups and disposed outside the second pixels (B, C). The parallax elements (4) make the different pixels of each group visible in different viewing regions. A control arrangement selects regions of the display and selects different combinations of the pixels of each group for image display within respective regions so as to provide simultaneously-present different viewing modes having different viewing range characteristics.Type: GrantFiled: February 20, 2009Date of Patent: November 11, 2014Assignee: Sharp Kabushiki KaishaInventors: Nathan James Smith, Benjamin John Broughton, Lesley Anne Parry-Jones, Jonathan Mather, Harry Garth Walton

Patent number: 8860703Abstract: A 2-dimensional (2D)/3-dimensional (3D) image display device generates 2D or 3D image data according to an input image signal and displays them on a display unit. The display unit includes a display panel for displaying an image in response to the 2D or 3D image data and an optical element layer operative during first and second driving modes in accordance with the 3D and 2D image data. A controller converts the optical element layer to be in the first driving mode in a first period before a 3D image signal is displayed when the input image signal changes from a 2D image signal to the 3D image signal, and converts the optical element layer to be in the second driving mode in a second period after the 2D image signal is displayed when the input image signal changes from the 3D image signal to the 2D image signal.Type: GrantFiled: June 25, 2013Date of Patent: October 14, 2014Assignee: Samsung Display Co., Ltd.Inventors: Seong-Cheol Han, Hui Nam, Hyoung-Wook Jang

Publication number: 20140268324Abstract: Methods and systems are described for use of a barrier grid to enable the perception of three-dimensional (3D) content from inherently two-dimensional (2D) captured images. When viewing the captured image as a photograph, transparency or image displayed on an electronic display such as LCD, plasma, or DLP, a spacer and a barrier grid with vertical lines is placed in front of the display the barrier grid separates the horizontally displaced components of the image and directs the separated components to the left and/or right eye. Similarly, the image can be provided by a rear-projector screen, in which the image was stored and displayed digitally, photographically, or rendered by a computer device. The disparity contained in the horizontal displacement is perceived as depth information in the human brain. The result is that the perceived image is a three-dimensional representation of the actual depth information contained in the scene.Type: ApplicationFiled: March 18, 2014Publication date: September 18, 2014Applicant: 3-D Virtual Lens Technologies, LLCInventor: Eric Rosenthal
