As shown together with fig. 1 to 5, the mobile advertisement large screen provided by the present invention includes a screen module and a projection module, wherein the projection module is responsible for projecting to the screen module, and the screen module is responsible for imaging.
Specifically, the screen module includes abase 3 for supporting and aprojection screen 1 fixed on an upper side of thebase 3, and the projection module includes acabinet case 4 and a projector provided inside thecabinet case 4. Further, alinear slide rail 33 is provided on the back side of thebase 3, and thecabinet housing 4 is slidably attached to thebase 3 by thelinear slide rail 33; aninclined projection groove 42 is formed in the top of thecabinet case 4, and the projector projects theprojection screen 1 through theinclined projection groove 42. When in actual use, thewhole base 3 is placed on the ground in an open space, so that the whole device can be supported; the projector can then be controlled to project onto theprojection screen 1 via theinclined projection slot 42.
By providing thelinear guide 33, the position of theentire housing 4 can be finely adjusted right and left, and the relative position between the projector and thescreen 1 is moved as the position of thehousing 4 is moved, so that the image projected by the projector is positioned at an appropriate position on thescreen 1.
Specifically, theprojection screen 1 includes a glass panel fixed on the upper side of thebase 3, the glass panel uses transparent tempered glass as a substrate, and an electric control holographic film is fixed on the back of the glass panel. In the actual imaging process, the electric control holographic film can present transparent and atomization effects according to actual needs, can be used in multiple ways, and can replace the effect of a projection curtain. After the electric control holographic film is atomized, the electric control holographic film has excellent picture reduction performance, high color reduction degree, high resolution and high definition.
It should be noted that thelinear slide rail 33 needs to be disposed at the middle of the back side of thebase 3, and only then, thehousing case 4 can make the image projected by the projector be in a proper position (which is usually near the center position of the projection screen 1) on theprojection screen 1 while moving along with thelinear slide rail 33. In addition, twocounterweight cabins 31 are arranged in thebase 3, and the twocounterweight cabins 31 are respectively arranged at two sides of thelinear slide rail 33; the twocounterweight cabins 31 are respectively arranged on the two sides of thelinear slide rail 33, so that the supporting stability and the balance of the whole device can be obviously improved.
