Abstract: A 3D display apparatus including lenticular lenses is provided. The lenticular lenses may be disposed between a display panel and a viewing angle control film. A direction in which the lenticular lenses extend may be inclined with a direction in which pixel regions of the display panel are arranged. The display panel may include light-blocking patterns overlapping with a boundary of the lenticular lenses. Thus, in the 3D display apparatus, the quality of the image provided to the user may be improved.

Abstract: A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.

Abstract: A stereoscopic display device having a barrier panel is provided. The barrier panel can include channel electrodes to form transmitting regions and blocking regions in an active area, and link lines to provide a signal to the channel electrodes. The stereoscopic display device can include a display driver driving a display panel; a barrier panel on the display panel, the barrier panel including channel electrodes across an active area, and link lines disposed outside the active area; and a barrier driver controlling the channel electrodes through the link lines, wherein the number of the link lines in which each channel electrode crosses, is constant. Thus, in the stereoscopic display device, a dark spot due to a load deviation of the channel electrodes can be prevented.

Abstract: A stereoscopic display device having a barrier panel is provided. The barrier panel may include channel electrodes across an active area. Each of the channel electrodes may include an end portion connected to corresponding link line. Each of the channel electrodes may be connected to the link line same as (n+1)th channel electrode from the channel electrode. The barrier panel may further include connecting lines to connect between opposite end portions of the channel electrode which are connected to the same link line. Thus, in the stereoscopic display device, the number of the wires extending along an edge of the active area may be reduced.

Abstract: 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.

Abstract: A three dimensional (3D) display apparatus can include lenticular lenses between a display panel and a viewing angle control film. The display panel can have a curvature. The viewing angle control film can include a plurality of light-blocking patterns between a first control substrate and a second control substrate. A pitch and a height of the plurality of light-blocking patterns can be determined by a curvature radius of the lenticular lenses, a distance between the viewing angle control film and a set viewing region, and a length of the display panel corresponding to the set viewing region. Thus, in the 3D display apparatus, the quality of 3D images provided to a user can be improved.
