The light-transmissive wall and the isolating ring (described later in detail) form an intervention cavity between the two adjacent light-transmissive walls, and the inner circumference of the spacer ring is provided with a cup-shaped groove 110, and the cup-shaped groove 110 is open to Its corresponding intervention cavity, each of which The intervention chamber contains at least two different colors and incompatible fluids, and the center of the sealed display panel extends vertically outwardly from a pivot 21; the outer edge of the holder 30 has a screw hole 32 through which the screw 63 passes. The screw hole 32 of the 30 is connected to the screw hole 62 of the rear case 60, so that the fixing frame 30 is fixed on the rear case 60. The fixing frame 30 further has a second bearing 33, and the pivot 21 of the sealing display plate 10 is in turn Positioned through the second bearing 33 of the fixing frame 30 and the first bearing 61 of the rear case 60, so that the sealing display panel can be rotated relative to the fixing frame 30, The utility model further includes a first pulley 40 fixed to a pivot 21 of the sealed display panel 10 and a second pulley 81 connected to the motor 80, the motor The second pulley 81 drives the second pulley 81. The second pulley 81 drives the first pulley 40 to rotate. Specifically, the first pulley 40 is centrally provided with a mounting hole 41, and is sleeved on the pivot 21, and the pivot 21 and the The mounting hole 41 has a matching non-circular cross section such that the pivot 21 can rotate with the first pulley 40, thereby driving the sealing display panel 10 to rotate about its pivot 21.

The sealed display panel 10 of the present invention has a plurality of interlaced light-transmissive walls and an isolating ring, and an interference cavity is formed between the two adjacent light-transmissive walls. The inner circumference of the spacer ring is provided with a plurality of cup-shaped recesses 110, the cup shape The groove 110 is open to its corresponding intervention cavity, and each of the intervention chambers contains at least two different colors and incompatible fluids, as shown in FIG. 5, FIG. 6, FIG. 7, FIG. The sealed display panel 10 of the device includes four light transmissive walls 100-103 separated by three spacer rings 104-106 to form three sealed intervention chambers 107-109, the above three The intervention chambers 107-109 are respectively filled with a fluid, one of which is a liquid and the other is a gas. In the specific embodiment of the present invention, the gas is air, and the color of the liquid in the intervention chamber is different, so that the intervention chamber The color of the inner fluid is also different. The cup-shaped recess 110 on the spacer is also sealed into the intervention chambers 107-109 formed by the transparent walls 100-103 and the spacers 104-106, and the two sides of the cup-shaped recess 110 on the spacer are respectively The light transmissive walls 100-103 are in contact to form a circumferentially extending groove 111, and the notch 113 is opened in the rotational direction.

Preferably, as shown in FIG. 2, FIG. 3, FIG. 4, and FIG. 8, the display device of the present invention further includes a lamp tube 50, the lamp tube 50 is fixed to the fixing frame 30, and is connected to the Circuit board 70, Specifically, the fixing frame 30 is provided with a plurality of card slots 31, and the lamp tube 50 is buckled in the card slot 31. The light transmissive wall 103 of the transparent wall 100-103 adjacent to the fixing frame 30 is The material of the scattered light is made ₀

Since the sealed display panel 10 is rotated about the axis perpendicular to its plane by the motor 80, the air in the intervention chambers 107-108 is mainly concentrated at the air gap 112 at the top of the intervention chamber, and the groove 111 at the top of the intervention chamber is collected. The gas is sent to the bottom region of the intervention chamber 107-108, and the air is released in the bottom region of the intervention chamber. As the sealed display panel rotates, the released air becomes discontinuous colorless bubbles due to the three The fluids in the intervention chambers 107-108 are different in color, and the entire sealed display panel 10 is light transmissive, and the transparent wall 103 is made of a material that can scatter light, so that the bulb 50 passes through the light having astigmatism. The screen 103 diverge the light emitted by the lamp tube 50 onto the entire sealed display panel 10. The colorless bubbles are colored bubbles on the premise of the colored liquid in the intervention chamber other than itself, and the above colored The color of the bubbles is not only the color of the liquid in the intervention chamber as the background, but the color of the fluid in the intervention chamber 107-109 is different. The body adds light to the human vision by the light emitted by the lamp 50 (this principle is similar to mixing pigments of different colors to produce a pigment of another color, such as mixing yellow and blue. It becomes a green effect, so that the color of the bubbles observed by our eyes is not limited to the color of the fluid in the intervention chamber 107-109.

Preferably, as shown in FIG. 5 and FIG. 6, the light transmissive wall further has a plurality of recesses 114, and the recesses 114 are formed in the light transmissive wall corresponding to the recesses 111, thereby increasing the capacity of the recesses 111.
