In general, stereoscopic image display devices are naked-eye stereoscopic image display devices, so that viewers can watch at an angle opposite to the display device, or the depth of an image cannot be far away from the display surface too much. However, in the case of taking into consideration some situation conditions, such as aeronautical terrain models, building models, medical 3D training, etc., when the display device is horizontally placed, the natural viewing angle of the viewer is to obliquely view the display device. In this case, the mainstream stereoscopic image display technology cannot provide a natural viewing angle for the viewer, which is inconvenient. Moreover, in general stereoscopic image display devices, the 3D perception viewed from the front surface is only visual stimulus in one direction for the viewer, which is just like the protrusion or sinking of the picture, but cannot achieve the sense of truly leaving the image out of the plane, so as to achieve the sense of floating in the air. In addition, in the existing stereoscopic image display device, the light source light distribution divergence angle of the display is large, so that when an observer moves, the observer can watch light rays of other orders, the quality is poor, and a better stereoscopic image display effect is difficult to achieve.

Detailed Description

First embodiment

The present invention provides an integrated stereoscopic image display device which can be applied to various industries such as photoelectricity, medical treatment, military, exhibition, display, education and entertainment, consumer electronics, etc., and can be applied to displays such as active type or passive type, etc., without limitation.

Referring to fig. 1 to 3, the integrated stereoscopic image display device includes a display 1, a lens array layer 2 and a baffle layer 3, and can change stereoscopic image frames seen by an observer at an angle position by changing display images, so that the observer can observe stereoscopic images at other angle positions.

The display 1 may be a generally flat display, and the display 1 has a display surface 11 for displaying images. The lens array layer 2 is arranged adjacent to the display surface 11 of the display 1, i.e. the lens array layer 2 may be arranged above the display 1. The lens array layer 2 may contact the display surface 11 of the display 1, or 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 undergone light reproduction, and this planar image may be subjected to light redistribution and combination by the lens array of the lens array layer 2, so as to display a reconstructed three-dimensional stereoscopic image. The display 1 of the first layer only needs to display the target image, so any hardware configuration including a mobile phone, a tablet or a flat screen is possible, the type and configuration of the display 1 are not limited, and the display 1 may 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 a three-dimensional object, so that the planar images which are not recombined originally can be redistributed and combined, and then a viewer can see the three-dimensional image.

The lens array layer 2 may include a base 21 and a plurality of lenses 22, the plurality of lenses 22 are disposed on one surface of the base 21, that is, the plurality of lenses 22 may be disposed on one surface of the base 21 away from the display 1, the arrangement and structure of the lens array layer 2 are not limited, the plurality of lenses 22 have a focusing function, and the image not yet reconstructed displayed on the display surface 11 can be recombined through the lens array layer 2 to form an integrated image, so as to form a stereoscopic image. The structure and material of the lens array layer 2 are not limited, and the plurality of lenses 22 may be, for example, cylindrical lenses (as shown in fig. 18), fresnel lenses (Fresnel lenses), or other various lens groups.

The present invention can view a three-dimensional image obliquely, and the oblique viewing mode means that the viewer is not facing the display 1, but can view the three-dimensional image. In the traditional naked-eye three-dimensional display, most of the three-dimensional display has the problem of viewing angle, and a viewer cannot see the three-dimensional display at an oblique angle. In the invention, the oblique viewing is the opposite, but a big feature, the viewer has a viewing angle limitation on the right and left in the direction (zero order viewing zone) opposite to the display 1, and once the viewing angle is exceeded, the viewer sees three-dimensional information which is supposed to be seen at the corresponding angle. In order to achieve oblique viewing of the stereoscopic image, a 0-order (forward) display mode is not adopted any more, and an oblique angle display mode is mainly adopted, so that the light paths are converged in an oblique direction, and a viewer can view the stereoscopic image in the oblique direction. In addition, the invention can also be added with a microstructure for guiding the light to the oblique view angle. However, the integrated stereoscopic image display apparatus of the present invention is equally applicable to viewing stereoscopic images at a forward angle, and does not limit the viewing angle.

The display 1 can be any standard as long as the algorithm is applicable, that is, the display 1 has an image calculating unit 12, so that the image used in the display 1 needs to be calculated by the image calculating unit, and the calculation is matched with the structure of the lens array to predict various paths of light rays traveling to calculate the relative position of the image. Since the image algorithm is the prior art and is not the key point of the present invention, the description is omitted.

The barrier layer 3 may be disposed on one side of the lens array layer 2, in this embodiment, the barrier layer 3 is disposed on the side of the lens array layer 2 near the display 1, i.e. the barrier layer 3 is disposed below the lens array layer 2, and the barrier layer 3 is disposed between the display 1 and the lens array layer 2.

The baffle layer 3 is a plate-like body including a plurality of baffles 31, and the plurality of baffles 31 are arranged at intervals and may be parallel or non-parallel to each other, and in this embodiment, the plurality of baffles 31 are parallel to each other. The spacing between the baffles 31 is not limited and may be varied as required, i.e. the baffles 31 may be densely or sparsely arranged as required, in this embodiment, the spacing between each two adjacent baffles 31 is smaller than the outer diameter of the lens 22, the spacing between each two adjacent baffles 31 is about half the outer diameter of the lens 22, and the baffles 31 are densely arranged. The distance between each two adjacent baffles 31 is less than 500 μm, for example, 100 μm, 200 μm, 300 μm, 400 μm or 499 μm, etc., preferably, the distance between each two adjacent baffles 31 is 100 μm to 130 μm, for example, 100 μm, 105 μm, 110 μm, 115 μm, 120 μm, 125 μm or 130 μm, etc., so that a plurality of baffles 31 can provide a better shading effect. The pitch of the plurality of baffles 31 may be a fixed value or a non-fixed value, that is, the pitch of the plurality of baffles 31 is not limited to an equal pitch, but may be an unequal pitch.

The plurality of baffles 31 rotate by an angle such that the plurality of baffles 31 extend along a first oblique direction a (as shown in fig. 2), specifically, the baffle layer 3 may be defined to have a reference edge 32, and in this embodiment, the reference edge 32 is a long edge of the baffle layer 3, and the plurality of baffles 31 respectively form a first included angle θ1 with the reference edge 32, so that the plurality of baffles 31 respectively have a rotation angle. The first angle θ1 is smaller than 90 degrees, so that the plurality of baffles 31 can provide better shading effect. The direction in which the baffle 31 rotates is not limited, and as shown in fig. 2, the baffle 31 forms a first angle θ1 with the reference edge 32 in the counterclockwise direction, but the baffle 31 may also form a first angle θ1 with the reference edge 32 in the clockwise direction.

The plurality of baffles 31 are inclined to the display surface 11, such that the plurality of baffles 31 extend along a second inclination direction B (as shown in fig. 3), and a second angle θ2 is formed between each of the plurality of baffles 31 and the display surface 11, such that each of the plurality of baffles 31 has an inclination angle. Since both shielding dimensions are required, the second angle (tilt angle) θ2 is preferably greater than 10 degrees. If the second angle θ2 (inclination angle) is too large, the viewing angle is too large, so the second angle θ2 (inclination angle) is preferably smaller than 80 degrees, that is, the second angle θ2 may be 10 to 80 degrees, for example, 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, etc. The second included angle θ2 of the entire surface structure may also be non-fixed, for example, the second included angle θ2 of the upper half is 30 degrees, and the second included angle θ2 of the lower half is 45 degrees.

A light-transmitting portion 33 is formed between every two adjacent baffles 31, the light-transmitting portions 33 are elongated, the light-transmitting portions 33 may be hollow (hollow), and the light-transmitting portions 33 may be solid with a light-transmitting material inside. An opening 34 is formed at an end of the light-transmitting portion 33 away from the display 1, and the opening 34 having a combined inclination angle and rotation angle may be directed toward the viewer or toward the opposite side of the viewer. The plurality of baffles 31 can provide a shading effect, so that the light generated by the display 1 can limit the divergence angle to eliminate the light of other orders, thereby having a better stereoscopic image display effect. The images displayed on the display surface 11 that have not been reconstructed can be recombined into an integrated image by the lens array layer 2 to form a stereoscopic image.

The baffle layer 3 can be disposed between the display 1 and the lens array layer 2, the baffle layer 3 can also be disposed (or formed) on the display 1 or the lens array layer 2, the baffle layer 3 can improve quality, so that the light generated by the display 1 can limit the divergence angle to irradiate to the lens array layer 2, and the light of other orders can be eliminated, so that the stereoscopic image display effect is better. The baffle layer 3 can limit the light to irradiate within a preset angle in the left and right directions (angle control) and the front and back directions (oblique angles), thereby eliminating the light of other orders and having better stereoscopic image display effect.

The lens array layer 2 of the present invention has a very important relationship to the display effect, and as shown in fig. 4, the lens arrays may be arranged in a rectangular arrangement, so that the lenses 22 of every two adjacent columns may be arranged in opposite directions. As shown in fig. 5, the lens array may be arranged in a hexagonal manner, so that the lenses 22 of every two adjacent rows may be arranged alternately, and the lens array may be arranged in other ways, so as to display 3D image information.

The microstructure on the lens array layer 2 is a lens with focusing function, the size of the micro lens will determine the focusing capability of the lens according to the refractive index n value of the material, and the wavelength range of the usable light is 300nm to 1100nm. The single lenslet focal length situation is shown in fig. 6, which conforms to the formula of the mirror builder: 1/f= (n-1) (1/R1-1/R2). Wherein R1 and R2 are the radii of curvature of the two sides of the lens, f is the focal length of the lens, and n is the refractive index of the lens. In addition, the lens diameter is from 100um to 5mm, which is suitable for the pixel size of different display devices.

The invention provides an integrated type optical component which is applicable to oblique viewing angles, and can control the light traveling direction of pixels at all positions in the device passing through the optical component by matching with hardware arrangement. The hardware system of the invention is a simple optical component, comprising a display 1, a lens array layer 2 and a baffle layer 3, which can be packaged into a suite, and the real image can be presented in a three-dimensional space by using the integrated image principle and matching with a screen output picture signal through a special algorithm through the designed pixel size, system gap, lens size and focal length.
