DETAILED DESCRIPTION
Referring to FIGS. 1 and 2, a multidimensional display apparatus 1, in accordance with a first exemplary embodiment, includes a main display screen 10, four reflective elements 11a-11d, and five display surfaces 12a-12e. The reflective elements 11a-11d are configured for reflecting light beams projected on reflection surfaces of the reflective elements 11a-11d. The main display screen 10 is a rectangular liquid crystal display (LCD) screen. The main display screen 10 is divided into five display areas, including a central display area 10a located in the center of the main display screen 10, and four display areas 10b-10e surrounding the central display area 10a, can display information thereon. The four reflective elements 11a-11d are respectively arranged above and inclined with respect to the display areas 10b-10e, with the reflection surfaces facing the corresponding display areas 10b-10e, respectively.
The five display surfaces 12a-12e are disposed corresponding to the five display areas 10a-10e. Wherein, the display surface 12a is disposed above the central display area 10a, and parallel to the central display area 10a. The display surfaces 12b-12e protrude vertically from the edges of the main display screen 10. Each of the display surfaces 12b-12e faces the reflection surfaces of the reflective elements 11a-11d, respectively.
The content displayed on the central display area 10a is viewable on the display surface 12a. The contents displayed on each of the display areas 10b-10e can be reflected by the corresponding reflective elements 11a-11d and are viewable on the corresponding display surfaces 12b-12e. The reflective elements and the display surfaces can vary in size and number in accordance with the sizes and the number of the display areas of the main display screen 10. In the embodiment, the four reflective elements 11a-11d are mirrors. In an alternative embodiment, the four reflective elements 11a-11d may be made of materials with reflection characteristic.
Referring to FIGS. 3 and 4, in a second embodiment, the multidimensional display apparatus 2 includes the round main display screen 20, two reflective elements 21a and 21b, and three display surfaces 22a-22c. The main display screen 20 is divided into three display areas 20a - 20c, including the central display area 20a in the center of the main display screen 20, and the two display areas 20b and 20c surrounding the central display area 20a. The reflection surfaces of the two reflective elements 21a and 21b face the display areas 20b and 20c. The display surface 22a is above and parallel to the display area 20a. The display surfaces 22b and 22c extend along the edge of the main display screen 20. The content displayed on the display area 20a is viewable on the display surface 22a, and the contents displayed on the display areas 20b and 20c are reflected by the reflective elements 21a and 21b correspondingly and viewable on the display surfaces 22b and 22c. User can watch the content displayed in any direction, surrounding the multidimensional display apparatus 1.
Referring to FIGS. 4-7, in a third embodiment, the multidimensional display apparatus 3 includes the main display screen 30, four reflective elements 31a-31d, and five display surfaces 32a-32e. The main display screen 30 is divided into five display areas, including a central display area 30a in the center of the main display screen 30, and four display areas 30b-30e surrounding the central display area 30a. The four reflective elements 31a-31d are all mirrors. The reflection surface of each of the four reflective elements 31a-31d faces and tilts with respect to the corresponding display area 30b-30e. The angle between each reflection element and its corresponding display area is about 45 degrees. The display surface 32a is above and parallel to the display area 30a. The display surfaces 32b-32e extend along the edge of the main display screen 30. The content displayed on the display area 30a is viewable on the display surface 32a, and the content displayed on the display areas 30b-30e are respectively reflected by the corresponding reflection elements 31a-31d and viewable on the corresponding display surfaces 32b-32e. 
Referring to FIG. 8, the content, reflected by the reflective element and viewable on the display surface as shown in portion (2), is reversed. For example, as shown in portion (1) of FIG. 8, “a1” and “a2” are contents displayed on the display area “a”. If a person views the display area directly, the “a1” is above the “a2”. However, after being reflected, the content viewed on the display surface “b” is that the “a2” is above the “a1”. That is, the reflected image on the display surface is a reverse of the original image displayed on the display area “a”. Therefore, to ensure that the reflected image can be normally shown on the display surfaces, the contents displayed on the display areas are preset to be reversed, inverted, or upside down.
Referring to FIG. 9, the size of the reflected content on the display surfaces, as shown in portion (2), varies as the angle between the reflective element and the corresponding display area changes. For example, as shown in portion (1) of FIG. 9, “d1” and “d2” are contents displayed on display area “d”. The angle between each reflection surface and its corresponding display area is about 60 degrees. It is clearly shown that, after being reflected, the size of the reflected content “d1” is about f/d times the size of the original image “d1”. Similarly, the size of the reflected image “d2” is about f/d times the size of the original image “d2”. The value of the radio f/d is determined by the angle between each reflection surface and its corresponding display area. Therefore, to ensure that the reflected image can be normally displayed on the display surfaces 32, the image displayed on the display areas are preset to be zoomed in or zoomed out according to the angels between the reflection surfaces of the reflective elements and the corresponding display areas.
It is understood that the present disclosure may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the disclosure is not to be limited to the details given herein.
