The structure of the flat lens 3 is described below with reference to fig. 4 to 8.

As shown in fig. 4 to 7, the flat lens 3 includes: the optical waveguide array 32 includes a plurality of optical waveguides 321, and the plurality of optical waveguides 321 are arranged in an array, and the optical waveguide array 32 is disposed between the two transparent substrates 31.

The material of the transparent substrate 31 may be at least one of glass, plastic, polymer and acrylic for protecting the optical waveguide array and filtering out excessive light.

Alternatively, as shown in fig. 6-8, the optical waveguide arrays 32 are divided into two groups, namely, a first optical waveguide array 33 and a second optical waveguide array 34, where the two groups of optical waveguide arrays 32 are each composed of a single-row optical waveguide 321 with a rectangular cross section and arranged obliquely at 45 °, and the two groups of optical waveguide arrays 32 are closely attached to each other on the same plane and are arranged orthogonally, that is, waveguide directions of mutually corresponding parts of the first optical waveguide array 33 and the second optical waveguide array 34 are mutually perpendicular. The two groups of optical waveguide arrays 32 can reduce the manufacturing difficulty of the optical waveguide 321, and can make the display image real and have high definition. Preferably, the first optical waveguide array 33 and the second optical waveguide array 34 have the same thickness, which is convenient for design and production. Specifically, as shown in fig. 6, the plate lens 3 includes a transparent substrate 31, a first optical waveguide array 33, a second optical waveguide array 34, and a transparent substrate 31 in this order from the display screen 2 side to the imaging groove 5 side. If the strength of the two sets of optical waveguide arrays 32 after being closely and orthogonally bonded is sufficient, or if the mounting environment has a limit in thickness, only one transparent substrate 31 may be disposed or the transparent substrate 31 may not be disposed at all.

As shown in fig. 6 to 8, the first optical waveguide array 33 and the second optical waveguide array 34 are composed of a plurality of optical waveguides 321 having rectangular cross sections, and the length of each optical waveguide 321 is limited by the peripheral dimension of the optical waveguide array so as to be different in length. The first optical waveguide array 33 has an optical waveguide 321 extending in the X direction, the second optical waveguide array 34 has an optical waveguide 321 extending in the Y direction, and the Z direction is the thickness direction of the optical waveguide array 32. The extending directions (optical waveguide array directions) of the optical waveguides 321 in the first optical waveguide array 33 and the second optical waveguide array 34 are mutually perpendicular, that is, the first optical waveguide array 33 and the second optical waveguide array 34 are orthogonally arranged as viewed from the Z direction (thickness direction), so that two light beams in the orthogonal directions are converged at one point, and the object image plane (light source side 35 and imaging side 36) is ensured to be symmetrical with respect to the planar lens 3, thereby realizing aerial imaging.

In other words, as shown in fig. 7, the first optical waveguide array 33 or the second optical waveguide array 34 is composed of a plurality of parallel-arranged optical waveguides 321 that are diagonally arranged with a 45 ° deflection from the user's viewing angle. Specifically, the first optical waveguide array 33 may be composed of optical waveguides 321 that are 45 ° side by side in the lower left direction and have a rectangular cross section, and the second optical waveguide array 34 may be composed of optical waveguides 321 that are 45 ° side by side in the lower right direction and have a rectangular cross section, and the arrangement directions of the optical waveguides 321 in the two sets of optical waveguide arrays may be interchanged.

Preferably, the adhesive 11 may be a photosensitive adhesive or a thermosetting adhesive, and the thickness of the adhesive 11 is T1, and T1>0.001mm is satisfied, for example, t1=0.002 mm or t1=0.003 mm or t1=0.0015 mm, and the specific thickness may be set according to specific needs. The adhesive 11 is provided between the adjacent optical waveguide arrays 32 and between the optical waveguide arrays 32 and the transparent substrate 31, thereby increasing the firmness.

In some embodiments, optical waveguide 321 is a reflective element. The cross section of the reflection unit may be rectangular, and one or both sides in the arrangement direction of the reflection unit are provided with the reflection film 10. Specifically, in the direction of the array arrangement of the optical waveguides, both sides of each reflecting unit are plated with a reflecting film 10, and the material of the reflecting film 10 may be a metal material such as aluminum or silver or other nonmetallic compound materials for realizing total reflection. The reflective film 10 functions to prevent stray light from entering the adjacent optical waveguide array due to no total reflection from affecting imaging. Alternatively, each reflection unit may be provided with a dielectric film on the reflection film 10, and the dielectric film may function to increase the light reflectance.

The principle of aerial imaging is explained below in connection with fig. 6-10. On the micrometer scale, any optical signal is orthogonally decomposed using a mutually orthogonal optical waveguide array 32 structure. The original signal is projected on the first optical waveguide array 33, and a rectangular coordinate system is established for the X1 axis by taking the projection point of the original signal as the origin and being perpendicular to the first optical waveguide array 33, and the original signal is decomposed into two paths of mutually orthogonal signals of a signal X1 positioned on the X1 axis and a signal Y1 positioned on the Y1 axis in the rectangular coordinate system. Wherein the signal X1 is totally reflected on the surface of the reflective film 10 at the same reflection angle as the incident angle while passing through the first optical waveguide array 33; at this time, the signal Y1 is kept parallel to the first optical waveguide array 33, passes through the first optical waveguide array 33, and is totally reflected on the surface of the reflective film 10 at the same reflection angle as the incident angle on the surface of the second optical waveguide array 34, and the reflected optical signal composed of the reflected signal Y1 and the signal X1 is mirror-symmetrical to the original optical signal. Therefore, the light rays in any direction can be mirror symmetrical through the flat lens 3, the divergent light of any light source can be converged into a floating real image again at the symmetrical position through the flat lens 3, the imaging distance of the floating real image is equal to the distance from the flat lens 3 to the image source, namely the display screen 2, the imaging is equidistant, the position of the floating real image is in the air, a specific carrier is not needed, and the floating real image is directly presented in the air. Thus, the image in the space seen by the user is the image emitted by the display 2.

In the embodiment of the present utility model, the light emitted from the light source of the display screen 2 passes through the plate lens 3, and the above process occurs on the plate lens 3. Specifically, as shown in fig. 10, the incident angles of the light rays on the first optical waveguide array 33 are α1, α2, and α3, respectively, the reflection angles of the light rays on the first optical waveguide array 33 are β1, β2, and β3, wherein α1=β1, α2=β2, α3=β3, and after being reflected by the first optical waveguide array 33, the incident angles on the second optical waveguide array 34 are γ1, γ2, and γ3, respectively, and the reflection angles on the second optical waveguide array 34 are δ1, δ2, and δ3, respectively, wherein γ1=δ1, γ2=δ2, and γ3=δ3.

Further, the incidence angles after convergence imaging are α1, α2, α … … αn, and the distance between the light source of the display screen 2 and the flat lens 3 is L, so that the imaging position of the floating real image and the distance between the flat lens are L, and the viewing angle epsilon of the floating real image is 2 times max (α).

It will be appreciated that if the size of the optical waveguide array is small, the image will only be visible at a distance from the imaging side of the optical waveguide array; and if the size of the optical waveguide array becomes larger, a larger imaging distance can be realized, so that the field of view is increased.

Preferably, the included angle between the panel lens 3 and the display screen 2 is set to be in the range of 45 ° ± 5 °, so that the size of the panel lens 3 can be effectively utilized, the imaging quality can be improved, and the afterimage effect can be reduced. Furthermore, if there is another requirement for the imaging position, other angles may be chosen at the expense of the imaging quality of the part, preferably the flat lens 3 being sized to display the picture of the floating real image 4 presented by the entire display screen 2. However, if only a part of the screen of the display 2 needs to be seen in actual use, the size and position of the plate lens 3 may be freely adjusted according to the actual display screen, which is not limited.

In other embodiments, alternatively, as shown in fig. 4 and 5, the optical waveguide array 32 is a group, and the group of optical waveguide arrays 32 includes a plurality of cubic columnar rectangular optical waveguides 321 arranged in a plurality of rows and columns at 45 ° oblique directions and having reflection films attached to the peripheral surfaces. The imaging principle of the two-layer optical waveguide array is the same as that of the double-layer optical waveguide array structure, and the two-layer optical waveguide array can also be used as the structure of the flat lens 3. The set of optical waveguide arrays 32 thus arranged is simple in structure and can make the display image true and clear.
