Flat naked-eye 3D display lenticular screen and manufacturing method thereof

Abstract

The invention discloses a flat naked-eye 3D display lenticular screen and a manufacturing method thereof. The lenticular screen is characterized in that the four edge-polished chamfers of a glass substrate are identical; a lenticular screen substrate is formed by a planar screen substrate on one surface, a semi-cylindrical curved surface on the other surface and groove belts arranged on the semi-cylindrical curved surface; numerous identical lenticular lenses are arranged on the semi-cylindrical curved surface in parallel; UV (ultraviolet) cured adhesives are arranged at the edge-polished chamfers of glass; the glass substrate with four edge-polished chamfers and the screen substrate with lenses are butt-jointed in a matching manner; the UV cured adhesives are subjected to UV irradiation;and the glass with four edge-polished chamfers and the lenticular screen substrate are packaged into a whole through vacuum exhaust. The lenticular screen and the manufacturing method have the following advantages: flatness of the large size lenticular screen substrate can be realized and the problem of parallelism matching between the non-flat lenticular screen and the periodic light field sent by a 2D display can be solved; and meanwhile, the manufacturing method is simple and low in cost and does not affect the quality of the 3D displayed graphics.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a flat naked-eye 3D display cylindrical lens grating and a manufacturing method thereof. Background technique [0002] Three-dimensional display (Three-dimensional Display, 3D) has become an eye-catching technology field today. Among them, naked-eye grating 3D display technology has become a research hotspot at this stage because it does not need to wear auxiliary equipment such as stereoscopic glasses. The grating 3D display is composed of a grating and a 2D display. The grating is used as a light splitting element, mainly including slit grating and cylindrical lens grating. Its purpose is to control the path of light transmission in a certain way, so that the viewer The left and right eyes see different parallax images. Although the splitting principles of slit grating and cylindrical lens grating are different, their effects are similar, and in many cases, the two gratings...

Problems solved by technology

[0004] In the cylindrical lens grating 3D display device, the pixels of the 2D display are arranged in an orderly periodic matrix structure, and the light field emitted by it also has a periodic matrix structure. However, the substrate with the cylindrical lens grating is usually transparent plastic, and different thicknesses The flatness of the plastic lenticular grating substrate is difficult to guarantee, and the parallelism between the uneven lenticular lenticular grating and the periodic light field emitted by the 2D display is difficult to achieve, which makes the 3D display effect of the lenticular lenticular grating worse, and even causes the image to fail to display normally.

[0005] Therefore, in order to overcome the difficulty in matching the unevenness of a single cylindrical lens grating and the parallelism of the periodic light field emitted by a 2D display, the present invention proposes a manufacturing method for realizing the flatness of a naked-eye 3D cylindrical lens grating
