As shown in fig. 2, the decorative panel 100 of the flat panel display device 10 for displaying dynamic decoration has a top surface 110 and a bottom surface 120, and it can be seen that the top surface 110 is opposite to the bottom surface 120. The trim panel 100 shown in fig. 2 is in the form of a sheet, with the top surface 110 and the bottom surface 120 both being planar; in other embodiments, the top surface of the trim panel may be non-planar, such as having a uniform or non-uniform distribution of protrusions, depressions, ridges, grooves, and combinations thereof on the top surface of the trim panel, and likewise, the bottom surface of the trim panel may have a similar configuration to the top surface of the trim panel.
According to this embodiment, a first decorative pattern (not shown) may be provided on the top surface 110 of the decorative panel 100, and the first decorative pattern may include various patterns or figures having decorative meaning, regular structure or irregular structure, may be a pattern created based on imagination, or may be a pattern created based on a pattern existing in nature.
According to another embodiment of the present application, a second decorative pattern (not shown) may be disposed on the second surface 120 of the decorative panel 100, and the second decorative pattern may include various patterns or figures having decorative meaning, regular structure or irregular structure, patterns created based on imagination, or patterns created based on patterns existing in nature. The second decorative pattern may be the same as or different from the first decorative pattern, so that a pattern different from both the first decorative pattern and the second decorative pattern can be formed by superimposing the second decorative pattern on the first decorative pattern.
In a preferred embodiment according to the present application, the first and second decorative patterns may be wood grains imitating a tree bark pattern. In other preferred embodiments according to the present application, the first and second decorative patterns may also be an annual ring line imitating an annual ring of a tree.
In the flat display device 10 for displaying dynamic decorations shown in fig. 1, the decorative plate 100 may be made of a light-transmitting thermoplastic material so that light can transmit through the decorative plate 100, and the decorative plate 100 may be flow-deformed when heated and may maintain a certain shape after cooling.
According to embodiments of the present application, the decorative sheet may be made of Polyethylene (PE), polypropylene (PP), Polystyrene (PS), Acrylonitrile Butadiene Styrene (ABS).
According to a preferred embodiment of the present application, the decorative plate may be made of polyvinyl chloride (PVC), and the PVC has good light transmittance, so that the flat panel display device for displaying dynamic decoration of the present application can most sufficiently display a dynamic decoration effect through the decorative plate.
The flat panel display device 10 for displaying dynamic decorations according to the present application will be described with continued reference to the accompanying drawings. Fig. 3 illustrates a schematic cross-sectional view of the top wall panel 200 in the flat panel display device 10 for displaying dynamic decorations shown in fig. 1. As shown in fig. 3, the top wall panel 200 of the flat panel display device 10 for displaying dynamic decoration has a sheet shape and has a top surface 210 and a bottom surface 220, and it can be seen that the top surface 210 of the top wall panel 200 is opposite to the bottom surface 220. Referring again to fig. 1, as shown, in the flat display device 10, the top surface 210 of the top wall panel 200 may be at least partially opposite the bottom surface 120 of the trim panel 100. In this embodiment, the bottom surface 120 of the trim panel 100 may completely cover the top surface 210 of the top wall panel 200.

Fig. 4 is a schematic cross-sectional view illustrating the bottom wall panel 300 of the flat display device 10 for displaying dynamic decorations shown in fig. 1. As shown in fig. 4, the bottom wall panel 300 of the flat panel display device 10 for displaying dynamic decoration is sheet-shaped and has a peripheral contour corresponding to that of the top wall panel 200, and as can be seen from the drawing, the bottom wall panel 300 is spaced apart from and substantially parallel to the top wall panel 200, and further, the bottom wall panel 300 has a top surface 310 and a bottom surface 320, wherein the top surface 310 is opposite to the bottom surface 320. Further, with continued reference to fig. 1, it can be seen that the top surface 310 of the bottom wall panel 300 faces the bottom surface 220 of the top wall panel 200.
According to an embodiment of the present application, the bottom wall panel 300 of the flat panel display device 10 for displaying dynamic decoration may be made of the same material as the top wall panel 200, or may be made of a different material from the top wall panel 200, for example, metal, wood, or the like.
Fig. 5 illustrates a schematic cross-sectional view of the peripheral wall plate 400 in the flat panel display device 10 for displaying dynamic decoration illustrated in fig. 1. As shown in fig. 5, the peripheral wall panel 200 of the flat panel display device 10 for displaying dynamic decoration is disposed between the top wall panel 200 and the bottom wall panel 300 and is substantially perpendicular to the top wall panel 200 and the bottom wall panel 300, so that the peripheral wall panel 400 defines an at least partially enclosed space 410 together with the top wall panel 200 and the bottom wall panel 300.
According to one embodiment of the present application, the peripheral wall plate of the flat panel display device for displaying dynamic decoration has a quadrangular shape with a rectangular cross section, and accordingly, the outer peripheral profiles of the top wall plate and the bottom wall plate are both correspondingly rectangular, so that the peripheral wall plate, the top wall plate and the bottom wall plate together form a tetrahedron. According to other embodiments of the present application, the peripheral wall panel of the flat panel display device may also be a corresponding column having a cross section of pentagon, hexagon, octagon, even circle, etc., and the outer peripheral profile of the top wall panel and the bottom wall panel is the corresponding pentagon, hexagon, octagon, even circle, etc., so that the peripheral wall panel and the top wall panel and the bottom wall panel jointly constitute the corresponding polyhedron, cylinder, etc. In these embodiments, the peripheral wall panel of the flat panel display device is in a circumferentially closed topology, such that the space defined by the peripheral wall panel together with the top wall panel and the bottom wall panel is a closed space.
