Description

Technical Field

[0001] The present invention relates to a display system, and in particular to a stereoscopic display system. Background Art

[0002] Using multiple monitors to form a display system can not only achieve the effect of a large display screen, but also improve work efficiency and increase entertainment effects. In order to increase the viewing field, the monitor located on the side can be simply rotated to an angle.

[0003] However, when the display system is a stereoscopic display system, rotating the stereoscopic display will cause the depth / position of the generated stereoscopic image in space to also be rotated, thereby making the depth / position of the stereoscopic images from different stereoscopic displays inconsistent in space, thereby causing a poor viewer experience. Summary of the invention

[0004] The invention provides a stereoscopic display system which can provide a good viewing effect.

[0005] One embodiment of the present invention provides a stereoscopic display system, which includes a first stereoscopic display, a second stereoscopic display, and a first controller. The first stereoscopic display is suitable for making the viewer's line of sight face the center of the display surface of the first stereoscopic display. The second stereoscopic display is suitable for being arranged next to the first stereoscopic display, and the first angle between its display surface and the extension surface of the display surface of the first stereoscopic display is greater than 0. The first controller signal is connected to the first stereoscopic display and is electrically connected to the second stereoscopic display. According to the first angle, the first controller controls the second stereoscopic display so that the stereoscopic image viewed by the viewer from the display surface of the second stereoscopic display is equivalent to the stereoscopic image from the display surface of the second stereoscopic display when the first angle is equal to 0.

[0006] Based on the above, in one embodiment of the present invention, the stereoscopic display system is designed as follows: the second stereoscopic display is suitable for being arranged next to the first stereoscopic display, and the first angle between its display surface and the extension surface of the display surface of the first stereoscopic display is greater than 0. Therefore, the stereoscopic display system can have a larger field of view. Furthermore, according to the first angle, the first controller controls the second stereoscopic display so that the stereoscopic image viewed by the viewer from the display surface of the second stereoscopic display is equivalent to the stereoscopic image from the display surface of the second stereoscopic display when the first angle is equal to 0. Therefore, in addition to the increase in the field of view, the stereoscopic display system can also produce good image content, so that the viewer has a better viewing experience.
