Abstract: A double-layered liquid crystal lens in which two liquid crystal layers are disposed, and a 3D display apparatus. In a 3D display mode, under control of an electric field, liquid crystal molecules of a first liquid crystal layer are deflected to form a plurality of first lenticular lens structures. In case of switching from the 3D display mode into a 2D display mode, under the control of an electric field, liquid crystal molecules in a second liquid crystal layer are deflected to form a plurality of second lenticular lens structures; the second lenticular lens structures are mirror symmetric to the corresponding first lenticular lens structures, so as to compensate a phase delay of a light modulated by the first lenticular lens structures, such that the light passes through the double-layered liquid crystal lens without deflection, and thus a normal 2D display state is realized.

Abstract: The embodiments of the present invention disclose a remote conference system and a method of performing the remote conference. The remote conference system includes a first image-displaying system, at a first conference location, configured to display images of a plurality of audiences; a detection system configured to detect motions or poses of at least part of heads of persons in the first conference location; a judgment system configured to judge whether a person who is talking is talking to a certain audience or some certain audiences of the plurality of audiences or is talking to all the audiences based on the motions or poses detected by the detection system; a second image-displaying system, at a second conference location, configured to display special images to the certain audience or some the audiences of the plurality of audiences when the judgment system has judged that the person who is talking is talking to the certain audience or some certain audiences of the plurality of audiences, such that the certain audience or some of the plurality of audiences is/are aware that the person who is talking is talking to him or them. Whereby, target audience(s) in the remote conference may know the person who is talking is talking to him or them.

Abstract: The present invention relates to a display device and a display method. The display device comprises a display panel and a video stream provider, wherein the display panel comprises a display screen and a separation module; the video stream provider provides one or two video streams, the one or two video streams are coded before entering the display screen to form a video signal source, and the video signal source is input to the display screen in a single-channel form; and when the video stream provider provides two video streams, the separation module separates a picture displayed in the display screen into two pictures respectively specific to the two video streams to realize double-view display. In the present invention, the two video streams are provided by the same video stream provider and may be previously coded, so that the complexity of transmission of the video signal source is greatly reduced.
