On the other hand, the fifth image beam L _E penetrates the penetration surface of the fourth transflective element 508 and is conducted to the upper user U _U . That is, the upper user U _U can simultaneously see the floating fifth display screen E, the seventh display screen G, and the fifth image beam L _E , the seventh image beam L _{G ,} and the eighth image beam L _H . The eighth display screen H. Similar to other embodiments, the upper user U _U and the lower user U _B see a multi-level floating image.

In the present embodiment, the floating projection display device 40 is comprised of a plurality of display panels 102, 104, 202, 204, 602, 702, 704, 802, 804 and a plurality of transflective elements 502, 504, 506, 508. The collocation can make the left user U _L , the right user U _R , the upper user U _U and the lower user U _B in different directions respectively view different multi-level images. On the other hand, by arranging the directional diaphragms 300, 400, 900, and 1000 on the display modules 100, 200, 700, and 800, it is possible to prevent the users U _R , U _L , U _U , and U _{B from} directly seeing the display. The confusion caused by the display on the panel allows the floating projection display device to be arbitrarily designed to be placed vertically or horizontally to achieve the best results in different applications. Furthermore, the floating projection display device 40 of the present embodiment can have a variety of uses. For example, in addition to being used as a display machine for exhibitions, it can also be used as a mahjong machine. In other words, each user U _R , U _L , U _U , U _B can view their own deck by different image beams. In view of the above, the floating projection display device 40 of the present embodiment can achieve a variety of different uses while providing good floating display quality.

In summary, the floating projection display device of the present invention can display multi-directional images by using a plurality of display panels and a plurality of semi-transparent elements, so that the user can view different image frames in different viewing directions. . In addition, since the transmission path of the image beam of each display panel is not the same, the image frame viewed by the user can exhibit a multi-layer effect. On the other hand, by arranging the directional film on the display module, the problem that the user directly sees the display on the display device in a specific direction and causes visual confusion can be reduced, so that the floating projection display device can be arbitrarily designed. Place it vertically or horizontally to match the best results for different applications.
