Patent number: 10466648Abstract: Disclosed herein is a holographic display which enables stereoscopic display of colors by changing a structure and mitigates a flickering effect by lowering the response speed. The holographic display may deliver an image to different positions for the left eye and right eye at the same time, thereby lowering the frequency necessary for supply of holographic image information. Thereby, the holographic display may address the issues of the afterimage effect and flickering effect in a liquid crystal panel-based spatial light modulator.Type: GrantFiled: November 22, 2016Date of Patent: November 5, 2019Assignee: LG Display Co., Ltd.Inventors: Yong-Ku Lee, Ju-Seong Park, Hyung-Seok Bang, Dong-Yeon Kim

Publication number: 20190204676Abstract: A transparent display apparatus is provided. The transparent display apparatus may include a display panel realizing an image. The image realized by the display panel may display on an image formed by light passing through the display panel. In the transparent display apparatus, the moving path of light emitted from the display panel may longer than the moving path of light passing through the display panel, so that the quality and the viewing angle of the image realized by the display panel may be improved.Type: ApplicationFiled: December 3, 2018Publication date: July 4, 2019Applicant: LG DISPLAY CO., LTD.Inventors: Ju-Seong PARK, Sung-Min JUNG, Sung-Woo KIM, Keong-Jin LEE, Myung-Soo PARK

Publication number: 20190196174Abstract: A display device including a display panel and an eyepiece is provided. An image realized by the display panel can be provided to a user by passing through the eyepiece. The display device can further include a front quarter-wave plate and a rear quarter-wave plate in order to increase the path of light traveling toward the eyepiece from the display panel. A barrier can be disposed between the front quarter-wave plate and the rear quarter-wave plate. The barrier can reflect or transmit the light traveling toward the eyepiece from the display panel on a region-by-region, so that the loss of light recognized by the user through the eyepiece can be minimized.Type: ApplicationFiled: November 29, 2018Publication date: June 27, 2019Applicant: LG DISPLAY CO., LTD.Inventors: Ju-Seong PARK, Sung-Min JUNG, Keong-Jin LEE
