Detailed Description
[ first embodiment ]
The present invention provides an integrated stereoscopic image display apparatus, which can be applied to various industries such as optoelectronics, medical treatment, military affairs, exhibition, display, educational entertainment, and consumer electronics, and the integrated stereoscopic image display apparatus can be applied to displays such as active type or passive type, without limitation.
Referring to fig. 1 and 2, the integrated stereoscopic image display apparatus includes a display 1, a lens array layer 2 and a gradient transmittance mask 3, which can change the stereoscopic image frame seen by the viewer at the angle position by changing the display image, so that the viewer can view the stereoscopic image at other viewing angle positions.
The display 1 may be a general flat panel display, and the display 1 has a display surface 11 for displaying images. The lens array layer 2 is disposed adjacent to the display surface 11 of the display 1, i.e. the lens array layer 2 may be disposed above the display 1. The lens array layer 2 may contact the display surface 11 of the display 1, and the lens array layer 2 may be disposed at a distance from the display surface 11 of the display 1, or an intermediate layer may be disposed between the display surface 11 of the display 1 and the lens array layer 2.
The display 1 may be disposed at the lowest layer and is responsible for displaying a planar image that has not been subjected to light ray reproduction, and the planar image may be subjected to light ray redistribution and combination by the lens array of the lens array layer 2, so as to display a recombined three-dimensional stereoscopic image. The display 1 of the first layer only needs to display the target image, and therefore may be any hardware configuration, including a mobile phone, a flat panel or a flat screen, the type and configuration of the display 1 are not limited, and the display 1 may also be a self-luminous display.
The lens array layer 2 can be arranged on the uppermost layer, the lens array layer 2 has the effect of regulating and controlling the light field, and the lens array layer 2 can regulate and control the light angle of the three-dimensional object, so that the originally non-recombined planar image is redistributed and combined, and a viewer can see the three-dimensional image.
The lens array layer 2 is made of a material with good optical properties, and the material of the lens array layer 2 is not limited. The lens array layer 2 may include a base 21 and a plurality of lenses 22, the plurality of lenses 22 are disposed on a side of the base 21, that is, the plurality of lenses 22 may be disposed on a side of the base 21 away from the display 1, the arrangement and the configuration of the lens array layer 2 are not limited, the plurality of lenses 22 have a focusing function, and the image displayed on the display surface 11 and not reconstructed can be recombined through the lens array layer 2 and recombined into an integrated image to form a stereoscopic image.
The present invention is characterized in that a three-dimensional stereoscopic image is viewed obliquely, and the oblique viewing mode means that a viewer can see the stereoscopic image without facing the display 1. In the conventional naked-eye three-dimensional display, most of the problems are that the viewing angle is not good, and the viewer cannot see the three-dimensional display at an oblique angle. In the present invention, the oblique viewing is a big feature, and the viewer has a visual angle limit on the left and right sides in the direction (zero-order viewing zone) opposite to the display 1, and once the visual angle is exceeded, the viewer sees no stereoscopic information corresponding to the viewing angle. In order to achieve the purpose of viewing the stereoscopic image in an oblique direction, the optical path is converged in the oblique direction by adopting an oblique angle display mode instead of a 0-order (forward) display mode, so that a viewer can view the stereoscopic image in the oblique direction. However, the integrated stereoscopic image display device of the present invention is equally applicable to viewing stereoscopic images at a forward angle.
The display 1 can be of any specification, as long as the algorithm is applicable, that is, the display 1 has an image calculation unit 12, the image used for the display 1 needs to be calculated by the image algorithm, and the calculation is matched with the structure of the lens array, so that various paths of light traveling of the display 1 are predicted, and the relative position of the image is calculated. Since the image algorithm is the prior art and is not the focus of the present invention, it will not be described in detail.
The lens array layer 2 of the present invention has a very important relationship to the display effect, and as shown in fig. 3, the arrangement of the lens array can be a rectangular arrangement, so that the lenses 22 in every two adjacent rows can be arranged oppositely. As shown in fig. 4, the arrangement of the lens array may be a hexagonal arrangement, so that the lenses 22 in each two adjacent rows may be staggered, and the lenses 22 may be arranged in other ways to display 3D image information.
The micro-structure on the lens array layer 2 is a lens with focusing function, the specification of the micro-lens determines the focusing capability of the lens according to the refractive index n of the material, and the wavelength range of the light can be 300nm to 1100 nm. The single lenslet focal length case is shown in FIG. 5, which conforms to the lensmaking equation: 1/f ═ (n-1) (1/R1-1/R2). Where R1 and R2 are the radii of curvature on either side of the lens, respectively, f is the focal length of the lens and n is the refractive index of the lens. In addition, the lens diameter size is from 100um to 5mm, which is suitable for the pixel size of different display devices.
The gradient transmittance mask 3 is disposed adjacent to the display surface 11 of the display 1, the gradient transmittance mask 3 may be disposed on a side of the lens array layer 2 close to or away from the display 1, the gradient transmittance mask 3 may also be directly sprayed on a top surface or a bottom surface of the lens array layer 2, in this embodiment, the gradient transmittance mask 3 is disposed on a side of the lens array layer 2 close to the display 1, that is, the gradient transmittance mask 3 is disposed below the lens array layer 2. The gradient transmittance mask 3 includes a plurality of mask units 31, the plurality of mask units 31 may be disposed on a substrate 32, the plurality of mask units 31 respectively correspond to the plurality of lenses 22, in the embodiment, the mask units 31 are circular corresponding to the lenses 22, however, the shape of the mask units 31 is not limited, and may also be other shapes, such as rectangular or hexagonal, etc. The shielding unit 31 has a gradually changing transmittance, and the transmittance of the shielding unit 31 can increase from the center to the edge, that is, the transmittance of the shielding unit 31 is the lowest at the center and the transmittance of the shielding unit 31 is the highest at the edge. In this embodiment, the shielding unit 31 may include a plurality of dots 311, the plurality of dots 311 may be made of a semi-transparent or opaque material, and the density of the plurality of dots 311 decreases from the center of the shielding unit 31 to the edge, so that the transmittance of the shielding unit 31 increases from the center to the edge.
The gradual transmittance mask 3 can be achieved by printing ink jet or photomask exposure, and the patterns with different gray scales can achieve the effect of different transmittances. In addition, different materials can be sprayed to have different penetration rates. The plurality of shielding units 31 may correspond to the plurality of lenses 22, respectively, the plurality of shielding units 31 may not correspond to the plurality of lenses 22, for example, one lens 22 may correspond to the plurality of shielding units 31. In addition, the shielding units 31 do not necessarily correspond to all the lenses 22, that is, only some of the lenses 22 are provided with the shielding units 31 for reducing the light intensity, and the other lenses 22 are directly penetrated. In addition, the shielding units 31 are not necessarily completely graded, and may have different penetration rates (for example, four, five, or six). The plurality of shielding units 31 may also be a multi-layer structure, for example, each layer is a concentric circle with different size, and stacked together to form the graded transmittance shield 3.
In the embodiment, taking the lens 22 as an example, when the pixels under one lens 22 are fully lighted, after imaging, because the light output amount of the edge of the lens 22 is small, the central image of the lens 22 is brighter than the edge image of the lens, thereby causing a grid feeling. The shielding units 31 respectively correspond to the lenses 22, and the transmittance of the shielding units 31 can be increased from the center to the edge, so that the brightness of the central image of the lens 22 can be reduced to weaken the light intensity, and the effect of the shielding units 31 with different transmittances can be utilized to make the brightness distribution uniform after imaging, without causing grid feeling.
In some configurations, it is also possible to make the pattern dark in the middle and bright beside it, so in another embodiment of the present invention (as shown in fig. 12), the transmittance of the shielding unit 31 can decrease from the center to the edge, i.e. the transmittance of the shielding unit 31 is the highest at the center and the transmittance of the shielding unit 31 is the lowest at the edge.
The invention provides an integrated type optical device which is suitable for forward and oblique viewing angles, and can control the light advancing direction of each position pixel in the device passing through an optical component by matching with hardware setting. The hardware system of the invention is a simple optical component, which comprises a display 1, a lens array layer 2 and a gradient penetration rate shield 3, and can be packaged into a suite, and the real image can be displayed in a three-dimensional space by using an integrated image principle and matching with a screen output picture signal through a special algorithm through the designed pixel size, system clearance, lens size and focal length.
In another embodiment of the present invention, the pixels of the display 1 can have different brightness by software, which is also equivalent to the effect of the gradient transmittance mask 3.
