Abstract

The invention discloses a grating type stereoscopic display device which comprises a display panel and a plurality of parallel gratings. The display panel is used for displaying an N-viewpoint view formed by arranging rectangular pixels in equal sizes, the clearances between the rectangular pixels form a plurality of first parallel black lines and a plurality of second black lines perpendicular to the first black lines, and the intersection points of the first black lines and the second black lines are black matrix intersection points. The parallel gratings are arranged in front of the display panel in an overlapped mode, and the grating pitch of each grating is a set value so that when at least one of the two parallel edges of each grating crosses with two adjacent first black lines, intersection points formed through crossing cannot be overlapped with the black matrix intersection points of two adjacent first black lines. The device and a method are used for solving the technical problem that in the prior art, serious Moire patterns exist on the displayed image of a naked-eye stereoscopic display device.

Description

technical field [0001] The invention relates to display technology, in particular to a grating type stereoscopic display device, a signal processing method and an image processing device. Background technique [0002] At present, the naked-eye stereoscopic display device is still in the research stage and has not been popularized in large quantities. Moreover, due to the limitations of the naked-eye display technology and signal processing technology, the naked-eye stereoscopic display device is not perfect. [0003] At present, the naked-eye three-dimensional (3D) autostereoscopic displays developed based on binocular parallax are mainly grating-type 3D autostereoscopic displays. It is formed by adding a grating on a 2D flat-panel display. The grating can be divided into cylindrical grating or slit grating, cylindrical grating is also called cylindrical lens grating or lenticular lens grating, and slit grating is also called visually impaired baffle or slit baffle. Using ...
