A black and white multi-shaped perforation linear slit type naked-view 3D imaging film

Abstract

The invention discloses black-white multi-shaped hole linear slit-type naked-eye 3D development film. The film is formed by vertically and periodically arraying a black linear coherent line shieldingshading area, a continuous non-color linear slit light transmission area and an interval non-color multi-shaped hole light transmission area which are aslant arranged. When a naked-eye 3D film sourceis played on a liquid crystal or plasma photoelectric development screen, the interiors and exteriors of development unit modules of the film and the development screen are precisely overlaid and coincided at intervals, and an image, similar to a nature real scene, with a clear three-dimensional layer can be displayed. Compared with slit-type naked-eye 3D development film, the film has the advantages that the range of 180-degree light transmission three-dimensional development of the film in the left, right, upper, lower, internal and external directions is greatly extended, the luminance andprecision of image display are truly improved, the phenomena of image moire patterns and white light line interference are obviously reduced, the field depth and field protrusion effects of the imageare deeper and more obvious, and it is sufficiently reflected that the film is invented successfully, wherein light electric waves carried with coloring waves are used for penetrating through hole slits, and the naked-eye 3D image can be directly diffracted and displayed.

Description

technical field [0001] The invention relates to the field of photoelectric display of naked-view 3D images, in particular to a black-and-white multi-shaped perforation linear slit-type optical imaging film capable of displaying naked-view 3D image pictures. Background technique [0002] At present, the photoelectric display imagers on the market can be divided into flat 2D, glasses-type 3D, and naked-eye (eye) 3D. [0003] Among them, the planar photoelectric display horizontal and vertical two-dimensional imager has a history of nearly 200 years, and the effect of its planar 2D imaging technology is becoming more and more perfect. However, the planar photoelectric display imager does not have the functions of vertical, middle, and near-level imaging, and cannot provide for People intuitively see the real three-dimensional image picture, such as Figure 15 (a) shown. [0004] The development of glasses-type 3D photoelectric display imager has a history of 100 years, such as...

Problems solved by technology

like Figure 4 As shown in (a) and (b), at present, the proportion of black shielding and white space color light-transmitting slits required to achieve an ideal naked-view 3D picture display effect is generally more than 2:1, so the brightness of the picture is reduced At the same time, the accuracy of the image display pixels on the screen is also reduced by about 50%, which causes serious low-brightness and low-resolution imaging defects. Therefore, it is necessary to use high-brightness LED lamp bead backlight for liquid crystal or The brightness of the plasma photoelectric display imager is heavily compensated

However, light compensation can only make up for the defect of brightness reduction to a certain extent, and has no obvious effect on the improvement of pixel accuracy.

Therefore, the image quality of the black-and-white linear slit grating naked-eye 3D imaging film is still far from the humanized demand for viewing naked-eye 3D images in a natural environment.
