Retouching should also be regarded as the scope of protection of the present utility model.

As shown in FIGS. 1 to 3 , the present invention provides a dimming display device, which includes a dimming screen 10 , a projection device 20 and a mounting frame 30 . The dimming screen 10 includes a transparent medium plate 11 and a dimming film 12 mounted on the back side of the transparent medium plate 11 . The transparent medium board 11 can use glass or acrylic board. The projection device 20 is arranged on the rear side of the dimming screen 10 .

The mounting frame 30 includes a fixing frame 31 and a supporting plate 32 directly behind the fixing frame 31 . The dimming screen 10 is fixed on the fixed frame 31 of the dormitory. The projection device 20 is fixed on the support plate 32 and the projected image can be imaged and displayed on the dimming screen 10 . Wherein, the shape of the dimming screen 10 can be cut and formed by cutting the transparent medium plate 11 and the dimming film 12 according to requirements, and then pasted together.

As shown in FIG. 3, in this embodiment, the fixing frame 31 includes a bracket 33, the bracket 33 has a U-shaped clamp 35 with an opening facing upward, and the dimming screen 10 is clipped on the U-shaped clamp.
