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: 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 liquid crystal barrier is configured to determine the viewing position of a viewer and selectively adjust based on the viewing position of the viewer. The liquid crystal barrier includes a barrier panel and a driving voltage supply unit. The barrier panel includes first electrodes, second electrodes, and liquid crystal layer. Opposite ends of the first electrodes are connected between 2n first channel lines, which form n channels, on a lower substrate. Opposite ends of the second electrodes are connected between 2n second channel lines, which form n channels, on an upper substrate. The liquid crystal layer is filled between the upper and lower substrates. The driving voltage supply unit is configured to supply at least one of a driving voltage and a common voltage to at least one of the first electrodes and the second electrodes.
