The invention reveals a naked-eye 3D display
system capable of carrying out lateral and vertical display, and the
system comprises a
signal processing device, an
image display device and an optical
grating image-splitting device, wherein the optical
grating image-splitting device is arranged in an inclined manner. The
system can achieve lateral-screen display, and can carry out anticlockwise 90-degree rotation to achieve vertical-screen display, the optical
grating is arranged to be inclined towards the right side, and compared with the vertical-screen display of a 3D video
signal, the lateral-screen display of the 3D video
signal enables a single viewpoint image to make 90-degree
clockwise rotation and the viewpoint arrangement position is not changed; or the system can achieve lateral-screen display, and can carry out
clockwise 90-degree rotation to achieve vertical-screen display, the optical grating is arranged to be inclined towards the left side, and compared with the vertical-screen display of the 3D video signal, the lateral-screen display of the 3D video signal enables the single viewpoint image to make 90-degree anticlockwise rotation and the viewpoint arrangement position is not changed. The system provided by the invention can achieve the lateral-screen or vertical-screen naked-eye 3D display according to the needs, and meets the demands of various applications. The system can improve the 3D
visual resolution and a 3D spatial effect, and can effectively reduce the design complexity.
