Please refer to Figures 1, 2, 3, 4 and 5, which are three-dimensional schematic diagrams of optical imaging switching devices of some embodiments, side views of the unfolded and folded imaging switching devices, and schematic diagrams of the paths of each section of the first optical path. The optical imaging switching device (hereinafter referred to as the imaging switching device 100) includes a display unit 110, a beam splitter 120, a concave reflection unit 130 and a first pivoting component 141.

The display unit 110 has a first display side 111 and a second display side 112 . The display unit 110 may be, but is not limited to, a liquid crystal display, and may also be a screen of a mobile device, or other types of displays. The display unit 110 provides a display light source 150 during operation. In FIGS. 2 and 3 , the side of the display light source 150 can be represented. Therefore, one side of the display unit 110 is represented by a thick black line segment as the side of the display light source 150 , and this side is called the display surface 113 . The first display side 111 and the second display side 112 are opposite sides of the display surface 113 . The display unit 110 can rotate between the original position (no label) and the projection position (no label), and the rotation process will be described separately later.

The beam splitter 120 has a first beam splitting side 121, a second beam splitting side 122 and a beam splitting mirror surface 123. The first beam splitting side 121 and the second beam splitting side 122 are opposite sides. The beam splitting mirror surface 123 is disposed between the first beam splitting side 121 and the second beam splitting side 122 and faces the side of the concave reflection unit 130. In the beam splitter 120 of FIG. 2, the beam splitting mirror surface 123 is indicated by a thick black line. The first hinge component 141 hinges the first display side 111 and the first beam splitting side 121. The display range of the display surface 113 is less than or equal to the range of the beam splitting mirror surface 123.

The first display side 111 of the display unit 110 rotates around the first hinge part 141, and the second display side 112 of the display unit 110 can rotate between the original position and the projection position. For the convenience of explanation, the display unit 110 is placed when the imaging switching device 100 is unfolded or folded, so the display unit 110 is located in the original position or the projection position as a synonym. The original position is that the display unit 110 is located in front of the beam splitter 120 after the imaging switching device 100 is folded, as shown in Figure 3. In contrast, the projection position is that the display unit 110 is located above the beam splitter 120 after the imaging switching device 100 is unfolded. When the display unit 110 is in the projection position, the second beam splitter side 122 can be against the concave reflection unit 130.

When the display unit 110 is at the original position, the display light source 150 of the display surface 113 will not be projected onto the dichroic mirror surface 123, as shown in FIG3. When the display unit 110 is at the projection position, the display unit 110 projects the display light source 150 onto the dichroic mirror surface 123. The dichroic mirror surface 123 partially reflects the light of the display light source 150 to the concave reflection unit 130, and this light is called the first light 151a. The black vertical arrow line segment in FIG4 is the light of the display light source 150, the black horizontal arrow line segment in FIG4 is the first light 151a, and the vertical dotted line segment is the light transmitted through the dichroic plate 120.

The concave reflection unit 130 has a first unit side 131, a second unit side 132 and a concave reflection surface 133, and the first unit side 131 and the second unit side 132 are opposite sides. The concave reflection surface 133 is arranged between the first unit side 131 and the second unit side 132. The concave reflection surface 133 reflects the first light 151a to the beam splitter 120. When the display unit 110 is in the original position, the concave reflection surface 133 is opposite to the beam splitter surface 123 of the beam splitter 120. The concave reflection unit 130, the beam splitter 120 and the display unit 110 are parallel to each other, as shown in FIG3.

In some embodiments, the angle between the optical axis of the concave reflective surface 133 and the beam splitter surface 123 is 45 degrees. The transmittance and reflectance of the beam splitter 120 depend on the coating material. For the convenience of explanation, the transmission and reflection of the beam splitter 120 are illustrated at an angle of 45 degrees in Figures 2, 4, and 5. The angle between the display unit 110 and the beam splitter 120 is 45 degrees, and the angle between the second light 151b and the beam splitter 120 is also 45 degrees.

When the display unit 110 is at the projection position, the second display side 112 is located at the first unit side 131 of the concave reflective unit 130. The second display side 112 can be fixed to the first unit side 131 by a buckle, a magnetic force or other fixing structure. The concave reflective unit 130 can reflect the first light 151a to the spectroscopic mirror surface 123, and the light reflected by the concave reflective unit 130 to the spectroscopic mirror surface 123 is called the second light 151b, please refer to the black horizontal arrow line segment in FIG. 4. The concave reflective unit 130 is used to enlarge the virtual image imaging range of the display unit 110, and the virtual image formed is hereinafter referred to as a virtual image 212. The magnification of the concave reflective unit 130 is determined according to the concave curvature. The dashed line segment on the right side of the concave reflective unit 130 is the imaging distance of the virtual image, which is called the virtual image distance 211.

When the second light 151b is reflected to the spectroscopic mirror surface 123, part of the second light 151b will be transmitted through the spectroscopic mirror surface 123, and the transmitted light is called the third light 151c. The user T can view the third light 151c and its corresponding virtual image 212 through the spectroscopic plate 120 and the concave reflection unit 130. The light path set formed by the display light source 150, the first light 151a, the second light 151b and the third light 151c is the first light path 151, please refer to Figure 2.

The display unit 110 is located at the projection position, and the optical path from the display unit 110 to the user T is the first optical path 151. The user T can view the enlarged virtual image 212 of the display unit 110 through the beam splitter 120 and the concave reflective unit 130. And after being reflected by the concave reflective unit 130, the virtual image 212 will also present a curved visual effect, as shown in FIG1. When the display unit 110 is located at the original position, the display light source 150 of the display unit 110 is directly projected to the user T, and this optical path is the second optical path 152.

In some embodiments, the imaging switching device 100 further has a second hinge component 142, see FIG6 . The second hinge component 142 is hinged to the second beam splitting side 122 and the second unit side 132. The beam splitter 120 rotates around the second hinge component 142, so that the first beam splitting side 121 can move away from or move closer to the first unit side 131. When the display unit 110 rotates to the projection position, the first beam splitting side 121 moves away from the first unit side 131, and the first unit side 131 abuts against the first display side 111, as shown in the lower part of FIG6 . The first unit side 131 can be fixed to the first unit side 131 by snapping, magnetic positioning or sleeve connection. At the same time, a projection space (no number) is formed between the display unit 110, the beam splitter 120 and the concave reflection unit 130 for reflection of the first light 151a and the second light 151b.

In some embodiments, the imaging switching device 100 further has a snap-fit structure 143, as shown in FIG. 7A and FIG. 7B. The snap-fit structure 143 has two first fixed arms 143a, two second fixed arms 143b, two first extension arms 143c and two second extension arms 143d. FIG. 7A is a right side view of the snap-fit structure. The two first fixed arms 143a are fixedly disposed on opposite sides of the beam splitter 120. The two second fixed arms 143b are fixedly disposed on opposite sides of the concave reflection unit 130. One end of the first fixed arm 143a is pivoted to one end of the second fixed arm 143b. One end of the first extension arm 143c is pivoted to the first fixed arm 143a, and the other end of the first extension arm 143c is pivoted to one end of the second extension arm 143d. The other end of the second extension arm 143d is hinged to the other end of the second fixed arm 143b.

When the display unit 110 is in the original position, the first extension arm 143c and the second extension arm 143d pivot and retract, so that the beam splitter 120 can abut against the concave reflection unit 130, as shown in FIG7A. When the display unit 110 is in the projection position, the two ends of the first extension arm 143c and the second extension arm 143d pivot and extend, respectively, so that the beam splitter 120 moves away from the concave reflection unit 130, as shown in FIG7B.

In some embodiments, the imaging switching device 100 further has a flexible connecting component 144, as shown in FIG. 7C. The flexible connecting component 144 is connected to the second light splitting side 122 and the second unit side 132 . When the second light splitting side 122 rotates about the axis, the flexible connecting component 144 provides a connection between the light splitting plate 120 and the concave reflection unit 130 so that the first light splitting side 121 can move away from or move closer to the first unit side. Side 131. The flexible connecting component 144 may be, but is not limited to, a flexible circuit board, and may also be Velcro, rubber or elastic cloth.

In some embodiments, the processing system for switching optical imaging (referred to as processing system 800) includes an imaging switching device 100, a display unit 110 and a processing unit 810, see Figures 8 and 9. The processing unit 810 is electrically connected to the display unit 110 and the imaging switching device 100. The display unit 110 provides a display light source 150 to the user T or the imaging switching device 100, and forms a first optical path 151 or a second optical path 152. The first optical path 151 and the second optical path 152 of the display unit 110 can refer to the above description.

The imaging switching device 100 has a beam splitter 120, a concave reflection unit 130, a first pivot component 141 and a sensing unit 161. The connection method and operation of the concave reflection unit 130, the beam splitter 120 and the first pivot component 141 can refer to the description of the previous embodiment. The sensing unit 161 is configured on the first unit side 131 of the concave reflection unit 130. The sensing unit 161 is used to detect whether the display unit 110 is located at the projection position. When the display unit 110 is located at the projection position, the display unit 110 abuts against and triggers the sensing unit 161, so that the sensing unit 161 generates a projection signal 911. The sensing unit 161 transmits the projection signal 911 to the processing unit 810. The sensing unit 161 can be implemented by a push switch, a reed switch, or a photoresistor. FIG9 takes the push switch as the sensing unit 161 as an example. When the display unit 110 is against the first unit side 121, the display unit 110 will press the sensing unit 161 until the display unit 110 is turned from the projection position to the original position.

The processing unit 810 is electrically connected to the display unit 110 and the sensing unit 161. The processing unit 810 outputs an image adjustment signal 820 according to the projection signal 911, and sends the image output adjustment signal to the display unit 110. The display unit 110 adjusts its own image parameters according to the image adjustment signal 820, thereby adjusting the content of the image played by the display unit 110.

To further illustrate the overall operation of the processing system 800, please refer to FIG. 10 , which is a schematic diagram of the operation flow of the processing system in some embodiments.

Step S910: The processing unit detects that the display unit is located at the original position or the projection position of the imaging switching device, wherein the first display side of the display unit is hinged to the imaging switching device, and the display unit rotates between the original position and the projection position with the first display side as the axis; Step S920: The display unit is located at the original position, and the display unit projects a display light source to the user to form a second light path; Step S930: The display unit rotates from the original position to the projection position, and the processing unit adjusts the image parameters of the display unit; and Step S940: When the display unit is located at the projection position, the display light source of the display unit is projected to the imaging switching device to form a first light path in the projection space of the imaging switching device.

First, the imaging switching device 100 is in a folded state, which means that the display unit 110 is in the original position. The user T can enable the display unit 110 to operate, and the display unit 110 projects the display light source 150 directly to the user T and forms a second light path 152, as shown in FIG3. The display unit 110 is rotated from the original position to the projection position, as shown in FIG2. When the display unit 110 is in the projection position, the display light source 150 is projected, and a projection space is formed between the display unit 110, the beam splitter 120 and the concave reflection unit 130. The display unit 110 projects the display light source 150 to the beam splitter 120 and the concave reflection unit 130.

In some embodiments, the imaging switching device 100 further has a second pivoting component 142. The second pivoting component 142 is connected to the second beam splitting side 122 and the second unit side 132. When the display unit 110 rotates from the original position to the projection position, the beam splitter 120 also rotates around the second pivoting component 142, so that the beam splitter 120 moves away from the concave reflection unit 130. In addition, the imaging switching device 100 can also be connected to the second beam splitting side 122 and the second unit side 132 respectively with a flexible connecting component 144.

In some embodiments, the sensing unit 161 can be disposed on the second unit side 132 of the concave reflective unit 130 (the sensing unit 161 is not shown). When the display unit 110 is at the original position, the sensing unit 161 will contact the beam splitter 120. When the display unit 110 rotates to the projection position, the sensing unit 161 can be released and generate a projection signal 911. Conversely, when the display unit 110 rotates from the projection position to the original position, the sensing unit 161 outputs a feedback signal 912 to the processing unit 810, so that the brightness of the display unit 110 is adjusted from the projection brightness to the initial brightness.

The image parameters include display area, display ratio, area brightness, image contrast, image sharpness or inverted image. The display area means the visible range of the display unit 110, please refer to Figures 11A and 11B. Figure 11A shows the display unit 110 in the original position, and Figure 11B shows the display unit 110 in the projection position. The dotted frame in the display unit 110 is the display area, and the display area can be regarded as the display surface 113.

When the display unit 110 is in the projection position, the first unit side 131 covers the bottom of the display area, as shown in FIG. 11B. Therefore, the processing unit 810 can send an image adjustment signal 820 to reduce the visible range, so that the visible range of the display unit 110 is scaled to a corresponding range. The processing unit 810 can adjust the display ratio of the display area of the display unit 110 according to the curvature of the concave reflection unit 130.

In addition to the adjustment of the display area, since the human eye's binocular viewing angle range is approximately 124 degrees. Therefore, the enlarged virtual image 212 needs to be within the range of the human eye's viewing angle. For concave imaging, the object distance is inversely proportional to the magnification. Taking a 16:9 32-inch display unit 110 as an example, the display unit 110 is approximately 76 cm wide and 45 cm high. The object distance between the beam splitter 120 and the concave reflection unit 130 is approximately 22.5 cm~30 cm (the range is determined by the curvature of the concave reflection surface 133). The image distance between the virtual image 212 and the user T in this range is approximately 1 m, and the range of the virtual image 212 is also close to the maximum value of the viewing angle. However, it is not limited to the display unit 110 of the aforementioned size, and the implementation described can also be applied to display units 110 of other sizes.

The processing unit 810 sends an image adjustment signal 820 to the display unit 110 to increase the brightness according to the ratio of the attenuation of the transmission/reflection brightness of the beam splitter 120. Here, the original brightness of the display light source 150 is referred to as the initial brightness, and the brightness of the display light source 150 after adjustment is the projection brightness. If the brightness after transmission/reflection of the beam splitter 120 is 50%. Since the display light source 150 is reflected twice and transmitted once, the first reflection is the beam splitter 120, the second reflection is reflected by the concave reflection unit 130, and the first transmission is the beam splitter 120. After the reflection of the beam splitter 120, the brightness of the display light source 150 decreases by 50%, and the reflection of the first light ray 151a by the concave reflection unit 130 does not cause a decrease in brightness, so the brightness of the third light ray 151c is 25% of the brightness of the display light source 150. Therefore, the processing unit 810 can drive the display unit 110 to adjust the brightness of the display light source 150 to 400% so that the brightness of the third light 151c is consistent with the brightness of the display light source 150 at the original position.
