A lenticular naked-eye 3D splicing screen and its manufacturing method

Abstract

The invention relates to the technical field of naked-eye three-dimensional display, and particularly relates to a cylindrical-lens type naked eye three-dimensional spliced screen and a manufacturing method of the cylindrical-lens type naked eye three-dimensional spliced screen. The manufacturing method of the cylindrical-lens type naked eye three-dimensional spliced screen includes the steps of evenly dividing four two-dimensional screens to be spliced into two sets, and splicing the two two-dimensional screens in each set in a preset mode to form two two-dimensional screen sets; covering the two two-dimensional screen sets with optical grating glass respectively, and splicing the optical grating glass and the two-dimensional screen sets in an edge-spliced mode to form two three-dimensional modules; splicing the two three-dimensional modules to form the cylindrical-lens type naked eye three-dimensional spliced screen. According to the cylindrical-lens type naked eye three-dimensional spliced screen and the manufacturing method of the cylindrical-lens type naked eye three-dimensional spliced screen, the two-dimensional screen splicing difficulty is lowered, the difficulty for unifying three-dimensional parameters of the two-dimensional screens is lowered, and the cylindrical-lens type naked eye three-dimensional spliced screen and the manufacturing method are low in cost and easy to implement, and can meet the demands of practical application.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D display, in particular to a lenticular-type naked-eye 3D splicing screen and a manufacturing method thereof. Background technique [0002] Compared with other current 3D display technologies, the lenticular glass-free 3D display technology has great advantages, especially in the advertising industry, the glass-free 3D display technology has considerable application prospects. At present, the size of various digital signages is getting bigger and bigger, and the demand for large-size glasses-free 3D displays in the advertising industry is also increasing. However, some difficulties will be encountered in the production of large-scale naked-eye 3D displays: ①In the case of the same resolution, the larger the screen and the larger the pixel pitch, the stronger the graininess of the produced naked-eye 3D display and the poorer the effect; ②The larger the screen, the greater its own deformation, ...

AI Technical Summary

Problems solved by technology

However, this method also has technical difficulties: ①The 2D screens used to make splicing screens are all narrow-sided screens (the edge width is generally 2-3mm), so the grating glass and the 2D screen can only be bonded on the entire surface. But the whole surface bonding technology is not yet mature, and the cost is relatively high

②In order to achieve a good naked-eye 3D display effect on the splicing screen, the alignment accuracy requirements of each 3D module during splicing are very high, and it is very difficult to realize in terms of technology

[0004] It can be seen from this that the existing method of making a lenticular naked-eye 3D splicing screen cannot meet the actual application requirements.
