Embodiment Construction

[0034] Reference will now be made in more detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Those of ordinary skill in the art should realize that the following description is only exemplary and not intended to be limiting in any way.

[0035] The invention provides a 3D display system. With the 3D display system, the viewer can watch the undeflected image displayed on the display device no matter where they are, without being limited by the viewing position. figure 2 shows a 3D display system according to an embodiment of the present invention, which will be combined below figure 2 The 3D display system will be described in detail. Such as figure 2 As shown, the 3D display system basically includes a display device 210, a detection device and a control device.

[0036] The display device 210 may be any type of display device, for example, a liquid crystal display (LCD), a projection display device, etc...

Abstract

A 3D display system and a 3D displaying method are provided in the present invention. The 3D display system comprising: a display device; a detecting device, for detecting a viewing position of a viewer; and a control device, for controlling a video frame to be converted onto a virtual plane perpendicular to visual line of the viewing position according to the viewing position, and mapping converted video frame onto the display device to display a 3D image on the display device. The 3D display system provided by the present invention adjusts the virtual plane, onto which the video frame is converted, by detecting the viewing position of the viewer, such that the 3D image displayed on the display device can be adjusted according to the viewing position of the viewer. It causes that the viewer can view the 3D image having no deflection, without being limited by the viewing position.

Description

technical field [0001] The present invention relates to the field of 3D technology, in particular to a 3D display system and a 3D display method. Background technique [0002] 3D technology is more and more widely used in modern life. 3D technology makes use of the slightly different angles of viewing objects with human eyes, so it can distinguish the distance of objects and produce a three-dimensional visual effect. Now, 3D display devices using 3D technology (for example, 3D TV, etc.) have gradually entered households. [0003] However, when viewing a 3D image 120 (such as a tetrahedron) on the display device 110, as figure 1 As shown, if the viewer is located directly in front of the display device 110 (ie position A), the 3D image seen is consistent with the 3D image 120 displayed on the display device 110 . If the observer is located in front of the display device 110 to the left (ie, position B), or is located in the front of the display device 110 to the right (ie,...
