Manufacturing method of large LED (light emitting diode) screen of 3D (three dimensional) television

Abstract

The invention relates to a manufacturing method of a large LED (liquid emitting diode) screen of a 3D (three dimensional) television, wherein a cylindrical surface grid screen technology used in the manufacturing method of the large LED screen display of 3D television signals solves the technical problem of a cylindrical surface grid screen of an LED luminotron combinational pixel array with three primary colors of red (R), green (G) and blue (B) on the premise of guaranteeing the multi-view display of a three-dimensional television (3DTV). A large LED screen display method of the 3D television comprises the following steps of: selecting a combinational pixel array module set unit of three primary colors of red (R), green (G) and blue (B) LED luminotrons, corresponding to cylindrical surface girds with different sizes according to the sizes of pixel elements, covering the girds on the surface of the LED luminotron combinational pixel array with three primary colors of red (R), green (G) and blue (B) by corresponding inclined angels, and finally splicing and fixing an LED luminotron combinational pixel array unit with the surface of the cylindrical surface grid films in a corresponding sequence to form a large LED screen of the 3D television.

Description

Technical field: [0001] The invention relates to LED (light-emitting diode) large-screen display technology for 3D video, in particular to the technology of a cylindrical grating film for a large LED screen. Background technique: [0002] At present, in the display applications of various analog signal video, VCD, DVD, digital signal TV, and emerging IPTV, mobile TV, etc., video playback is displayed on the flat panel display by international standards and other non-standard methods. It belongs to 2D video and its display technology. Free Viewpoint Video (FVV) or Free Viewpoint Television (FTV) is a new 3DTV visual technology developed rapidly at the beginning of this century. Three-dimensional (3D) video displays more closely match human vision than two-dimensional (2D) video displays. It can reproduce the depth / parallax information lost in the scene reproduction of 2D video, so that people have a sense of three-dimensionality and immersion when watching images on the scr...

AI Technical Summary

Problems solved by technology

[0004] (1) The 3D stereoscopic display has not been considered from the perspective of the overall FTV system. In fact, the display method is closely related to the number of viewpoints of the 3D video. The more the number of viewpoints, the wider the visual range of the stereoscopic effect, but the display resolution also decreases. Therefore, The number of viewpoints of the system should be considered in conjunction with the display resolution

[0005] (2) Most of the existing methods only use horizontal parallax or symmetrical total parallax. The former will cause a serious imbalance between the horizontal resolution and vertical resolution of the display, and the latter will aggravate the decrease in display resolution with the number of viewpoints. , both of which limit display resolution and viewing comfort

[0006] (3) The 3D display of FTV should be compatible with the traditional 3D display, but the existing methods are not compatible
