A barrier panel includes a first substrate and a second substrate having block region and transmission region; a liquid crystal layer between the first and second substrates, the liquid crystal layer including a plurality of liquid crystal molecules aligned in a predetermined direction; a plurality of barrier electrodes in the block region and the transmission region of the first substrate; a common electrode on the second substrate to apply an electric field to the liquid crystal layer with the plurality of barrier electrodes; a diffraction unit in the plurality of barrier electrodes to diffract the light transmitting therethrough; and a polarization plate over the second substrate, wherein an optical axis direction of the polarization plate is parallel to the alignment direction of the liquid crystal molecule to transmit an image through an area where the electric field is not applied.

Barrier panel and 3D display device having thereof

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.

Stereoscopic display device having a barrier panel

A parallax barrier according to an example can include a first substrate and a second substrate, a liquid crystal layer between the first substrate and second substrate, at least one insulating layer on the first substrate, a first electrode on the second substrate, a second electrode and a third electrode on the insulating layer to generate electric field in order to transmit and block selectively an image, a plurality of first spacers on the first substrate, and a plurality of second spacers on the second substrate. The first spacers and the second spacers can be formed in regions corresponding to each to maintain gap between the first substrate and the second substrate. Further, the first spacers can be spaced apart from the corresponding second spacers by a predetermined distance.

Switchable barrier and 3D display device having thereof

A stereoscopic display apparatus is disclosed. In the stereoscopic display apparatus, each unit pixel of a display panel includes a first transparent region. A barrier panel on the display panel may include second transparent regions overlapping with the first transparent region of each unit pixel. Thus, in the stereoscopic display apparatus, the transparency may be improved without the quality deterioration of a stereoscopic image.

Stereoscopic display apparatus

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.

A stereoscopic display device having a barrier panel is provided. The barrier panel may include lower channels between a lower barrier substrate and a channel insulating layer. The lower channels may be disposed between upper channels which is disposed on the channel insulating layer. Each of the lower channels may include a first sub-channel, a second sub-channel and a lower insulating layer. The lower insulating layer of each lower channel may cover an end region of the first sub-channel of adjacent lower channel. The second sub-channel of each lower channel may be connected to another end region of the first sub-channel. The second sub-channel may be extended along a side wall of the lower insulating layer. Thus, in the stereoscopic display device of the present disclosure, a distance between the lower channels may be minimized.

A stereoscopic display device includes 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 of the active area; a front linear polarizer and a rear linear polarizer in direct contact with the barrier panel, respectively; and an image linear polarizer disposed on an outer surface of the display panel, wherein the number of the link lines in which each channel electrode crosses, is constant.

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.

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.
