Field of the Invention
The invention relates to a floating image display apparatus and more particularly relates to a floating image display apparatus having a directional film and a plurality of transflective elements.
Description of Related Art
The continuous rapid changes of science and technology indicate that the display techniques are also continuously improved. In recent years, apparatuses that can project floating images are also proposed. A conventional floating image display apparatus includes an upper display screen matched with a piece of transflective element, such that an image displayed by the upper display screen can be reflected by the transflective element, thereby allowing a user to see a floating image.
However, the conventional floating image display apparatus has many limitations in terms of viewing angles and placement. For example, the conventional floating image display apparatus only presents a floating image with a single depth, and the user can only view the floating image from a single direction. Furthermore, if viewing upward from below, the user may see the image displayed by the upper layer display directly, interfering with the floating image effect. In other words, the conventional floating image display apparatus can only be placed upright; otherwise, the user would directly see the image displayed by the upper layer display.
The invention provides a floating image display apparatus, which provides images having a multi-layered effect in a plurality of directions, and reduces an issue of visual confusion caused by directly seeing the image displayed on the display apparatus from specific directions.
The invention provides a floating image display apparatus including a plurality of display modules, a first directional film, and at least one transflective element. The plurality of display modules include a first display module and a second display module. The first display module includes a first display panel and a second display panel. The second display module is located on an opposite side to the first display module and includes a third display panel and a fourth display panel. The third display panel is disposed corresponding to the first display panel, and the fourth display panel is disposed corresponding to the second display panel. The first directional film is disposed on the first display module and is located between the first display module and the second display module. The transflective element is located between the first display module and the second display module, and each of the transflective element and the second display module form an included angle θ1.
In an embodiment of the invention, the first display panel and the second display panel display different images, and the third display panel and the fourth display panel display different images.
In an embodiment of the invention, the floating image display apparatus further includes a second directional film, disposed on the second display module and located between the second display module and the first display module.
In an embodiment of the invention, the first display panel and the second display panel are formed integrally, and the third display panel and the fourth display panel are formed integrally.
In an embodiment of the invention, the first display panel and the second display panel are separated from each other, and the third display panel and the fourth display panel are separated from each other.
In an embodiment of the invention, the plurality of display modules further include a third display module, disposed between the third display panel and the fourth display panel, and the third display module includes a fifth display panel.
In an embodiment of the invention, light exiting directions of the first display module and the second display module and a light exiting direction of the third display module have an included angle α1, and 0°≦α1≦90°.
In an embodiment of the invention, the plurality of display modules further include a fourth display module, a fifth display module, a third directional film, and a fourth directional film. The fourth display module includes a sixth display panel and a seventh display panel, and a light exiting direction of the fourth display module and the light exiting direction of the third display module have an included angle α2, and 0°≦α2≦90°. The fifth display module is located on an opposite side to the fourth display module and includes an eighth display panel and a ninth display panel. The eighth display panel is disposed corresponding to the sixth display panel, the ninth display panel is disposed corresponding to the seventh display panel, and a light exiting direction of the fifth display module and the light exiting direction of the third display module have an included angle α3, and 0≦α3≦90°. The third directional film is disposed on the fourth display module and is located between the fourth display module and the fifth display module. The fourth directional film is disposed on the fifth display module and is located between the fifth display module and the fourth display module. The transflective element is located between the fourth display module and the fifth display module.
In an embodiment of the invention, the transflective element is a planar structure.
In an embodiment of the invention, the transflective element is a curved structure.
Accordingly, by coordinating the plurality of display panels and the plurality of transflective elements, the floating image display apparatus of the invention presents multi-directional images, such that users may view different images from different viewing angles. Furthermore, since the transmission path of the image light beam of each of the display panels is different, the images viewed by the users may present a multi-layered effect. In another aspect, by disposing the directional films on the display modules, the issue of visual confusion caused by the users directly seeing the image on the display panels in specific directions is reduced, such that the floating image display apparatus can be arbitrarily designed to be placed vertically or horizontally to achieve optimal effects corresponding to different occasions of application.

The first directional film 300 is disposed on the first display module 100 and is located between the first display module 100 and the second display module 200. The second directional film 400 is disposed on the second display module 200 and is also located between the first display module 100 and the second display module 200. In other words, the first directional film 300 and the second directional film 400 are disposed on different display modules. More specifically, the first directional film 300 is, for example, disposed on a surface of the first display panel 102 and the second display panel 104, and the second directional film 400 is, for example, disposed on a surface of the third display panel 202 and the fourth display panel 204. In the present embodiment, the first directional film 300 and the second directional film 400 focus light in a single direction or only allows a single direction of light to pass. That is, the first directional film 300 and the second directional film 400 allow light emitted from the first display panel 102, the second display panel 104, the third display panel 202, and the fourth display panel 204 to only transmit in a specific direction. For example, the first directional film 300 and the second directional film 400 include a display privacy filter, an automobile thermal insulation paper, or a directional optical film, but the invention is not limited thereto. A material able to focus light in a single direction or only allows a single direction of light to pass can all serve as the first directional film 300 and the second directional film 400 in the invention.
The transflective element module 500 is disposed between the first display module 100 and second display module 200, and includes at least one transflective element. In the present embodiment, the transflective element module 500, for example, includes a first transflective element 502 and a second transflective element 504. Material of the transflective element module 500 includes glass, film, acrylic or other transflective materials, and the invention does not limit the material of the transflective element module 500. The first transflective element 502 is disposed corresponding to the first display panel 102 and the third display panel 202, and second transflective element 504 is disposed corresponding to the second display panel 104 and the fourth display panel 204. More specifically, the first transflective element 502 is located between the first display panel 102 and the third display panel 202, and for example, is in direct contact with the first display panel 102 and the third display panel 202. However, in other embodiments, the first transflective element 502 may not be in direct contact with the first display panel 102 or the third display panel 202. The first transflective element 502 and the third display panel 202 of the second display module 200, for example, form a first included angle θ1, and 0°<θ1<90°. In other words, the first transflective element 502 is inclinedly placed between the first display panel 102 and the third display panel 202, as shown in

Bearing the above in mind, after being emitted by the second display panel 104, the second image light beam LB travels along a reverse direction of the Y-axis first and is being changed to travel along a direction of the X-axis after being reflected by the reflecting surface of the second transflective element 504, so as to be transmitted to a location of a right side user UR. Similarly, after being emitted by the third display panel 202, the third image light beam LC travels along a direction of the Y-axis first and is being changed to travel along a direction of the X-axis after being reflected by the reflecting surface of the first transflective element 502, so as to be transmitted through a transmitting surface of the second transflective element 504 to the location of the right side user UR. That is, through the second image light beam LB and the third image light beam LC, the right side user UR simultaneously sees the second display image B and the third display image C floating. It is worth noting that due to a difference in imaging positions, the image seen by the right side user UR has a multi-layered overlapping effect. More specifically, since the second transflective element 504 is closer to the right side user UR relative to the first transflective element 502, the second display image B (reflected by the second transflective element 504) viewed by the right side user UR is closer than the third display image C (reflected by the first transflective element 502). It is worth noting that in the embodiment, the display images A to D of all of the display panels 102, 104, 202 and 204 are all on the XZ-plane. Thus, light exiting directions of the first display module 100 and the second display module 200 both extend along the Y-axis and are parallel to each other.
In the present embodiment, by coordinating a plurality of display panels 102, 104, 202 and 204 and a plurality of transflective elements 502 and 504, the floating image display apparatus 10 allows the left side user UL and the right side user UR located at different directions to view different multi-layered images, respectively. In another aspect, by disposing the directional films 300 and 400 on the display modules 100 and 200, the users UR and UL are prevented from visual confusion caused by directly seeing the display images on the display panels, thereby enhancing the floating display quality. Furthermore, when the floating image display apparatus 10 is applied to exhibitions, the physical object of the image displayed by the display panel can be placed in a space formed by the first transflective element 502 and the second transflective element 504 for appreciation by users.

In another aspect, by disposing the directional films 300 and 400 on the display modules 100 and 200, the users UR and UL are prevented from visual confusion caused by directly seeing the display images on the display panels, thereby enhancing the floating display quality. Furthermore, the floating image display apparatus 20 of the embodiment has multiple purposes. For example, besides serving as a merchandise display machine at exhibitions, it can also serve purposes of a gaming machine. In other words, the fifth image light beam LE may serves as an image light beam of a card table. The left side user UL sees his or her own hand through the first image light beam LA and the fourth image light beam LD, and the right side user UR sees another set of hand through the second image light beam LB and the third image light beam L. Bearing the above in mind, the floating image display apparatus 20 of the present embodiment is able to achieve multiple purposes while providing good floating display quality.

Bearing the above in mind, after being emitted by the seventh display panel 704, the seventh image light beam LG travels along a direction of the X-axis first and is being changed to travel along a direction of the Z-axis after being reflected by the reflecting surface of the fourth transflective element 508, so as to be transmitted to a location of an upper user UU. Similarly, after being emitted by the eighth display panel 802, the eighth image light beam LH travels along a reverse direction of the X-axis first and is being changed to travel along a direction of the Z-axis after being reflected by the reflecting surface of the third transflective element 506, so as to be transmitted through a transmitting surface of the fourth transflective element 508 to the location of the upper user UU. In another aspect, the fifth image light beam LE penetrates the transmitting surface of the fourth transflective element 508 to transmit to the upper user UU. That is, through the fifth image light beam LE, the seventh image light beam LG, and the eighth image light beam LH, the upper user UU simultaneously sees the fifth display image E, the seventh display image G, and the eighth display image H floating. Similar to other embodiments, the images seen by the lower user UB and the upper user UU are multi-layered floating images.
In the present embodiment, by coordinating a plurality of display panels 102, 104, 202, 204, 602, 702, 704, 802 and 804 and a plurality of transflective elements 502, 504, 506, and 508, the floating image display apparatus 40 allows the left side user UL, the right side user UR, the upper user UU, and the lower user UB located at different directions to view different multi-layered images, respectively. In another aspect, by disposing the directional films 300, 400, 900, and 1000 on the display modules 100, 200, 700, and 800, the users UR, UL, UU, and UB are prevented from visual confusion caused by directly seeing the display images on the display panels, such that the floating image display apparatus can be arbitrarily designed to be placed vertically or horizontally to achieve optimal effects corresponding to different occasions of application. Furthermore, the floating image display apparatus 40 of the present embodiment has multiple purposes. For example, besides serving as a merchandise display machine at exhibitions, it can also serve purposes of a mahjong machine. In other words, each of the users UR, UL, UU, and UB sees his or her own set of hand through different image light beams. Bearing the above in mind, the floating image display apparatus 40 of the present embodiment is able to achieve multiple purposes while providing good floating display quality.
In summary of the above, by coordinating the plurality of display panels and the plurality of transflective elements, the floating image display apparatus of the invention presents multi-directional images, such that the users may view different image from different viewing angles. Furthermore, since the transmission path of the image light beam of each of the display panels is different, the images viewed by the users may present a multi-layered effect. In another aspect, by disposing the directional films on the display modules, the issue of visual confusion caused by the users directly seeing the display image on the display panels in specific directions is reduced, such that the floating image display apparatus can be arbitrarily designed to be placed vertically or horizontally to achieve optimal effects corresponding to different occasions of application.
