A black and white multi-shaped perforated curved slit type naked-view 3D imaging film

Abstract

The invention discloses a Black-white multi-shape eyelet arc-shaped slit type naked-view 3D image-displaying film, which is formed by vertically and periodically arranging black arc-shaped coherent line shielding and light shading regions, continuous empty chromatic arc-shaped slit light transmission regions and spaced empty chromatic multi-shape eyelet light transmission regions which incline leftwards or rightwards. When playing a naked-view 3D film source on a liquid crystal or plasma image-displaying screen, an image with distinct three-dimensional gradations as a real scene of the naturecan be displayed when image-displaying unit modules of the black-white multi-shape eyelet arc-shaped slit type naked-view 3D image-displaying film and image-displaying unit modules of the image-displaying screen are precisely superposed at intervals from inside to outside. Compared with a slit type grating naked-eye 3D image-displaying film, the black-white multi-shape eyelet arc-shaped slit typenaked-view 3D image-displaying film greatly expands a three-dimensional image displaying range of the film capable of transmitting light at 180 degrees leftwards, rightwards, upwards, downwards, inwards and outwards, truly improves the image display brightness and precision, significantly reduces the phenomenon of image crosstalk by moire and white-light lines, makes the field-depth and field protruding effects of the image more profound and prominent, and fully reflects that the black-white multi-shape eyelet arc-shaped slit type naked-view 3D image-displaying film is successfully invented byutilizing the effect of displaying a naked-view three-dimensional image through perpendicular incidence and diffraction when a photoelectric wave carrying a chromatic wave penetrates a hole seam.

Description

technical field [0001] The invention relates to the field of photoelectric display of naked-view 3D images, in particular to an optical imaging film capable of displaying naked-view 3D image pictures with black shielding, light-shielding and white-colored light-transmitting multi-shaped perforated arc-shaped slits. Background technique [0002] The optoelectronic display imagers currently on the market can be divided into flat 2D, glasses-type 3D, and naked-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 19 (a) shown.

Problems solved by technology

like Figure 5 As shown, at present, the ratio of black shielding and white space light transmission lines required to achieve an ideal naked-view 3D picture display effect is generally more than 2:1, so that the picture display brightness is reduced by about 50%, and the picture display The accuracy of image pixels is also correspondingly 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 to monitor the brightness of liquid crystal or plasma photoelectric display imagers. massive compensation

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.
