Embodiment Construction

[0027] A specific embodiment of the present invention is attached by the above description.

[0028] Its structure is described in detail as follows: a rolling double-sided projection screen see attached figure 1 with 2 , Including tubular motor 1, curtain 2, curtain vertical axis 3, electric control box 30 and wire plug 31. The tubular motor 1 is used as a screen driving reel. The tubular motor 1 is buckled and covered in the "∏" shaped cover 6. The two ends of the "∏" shaped cover are fixed on the two end seats 8 of the tubular motor, see attached figure 1 , 3 , 4 and 6. The curtain 2 is a closed loop double-sided curtain, the upper end of which is wrapped on the tubular motor 1 and the lower end of the curtain is wrapped on the vertical shaft 3 of the curtain. The tubular motor 1 and its control box 30 control the closed loop rolling operation.

[0029] The curtain of the present invention is formed by connecting a front curtain 21 and a rear curtain 22. The front and rear cu...

Abstract

A rolling-type double-side projection curtain relates to a peripheral product curtain of a projector technology. The curtain comprises a tubular motor, the curtain, a curtain vertical shaft, an electric control box and a lead plug. A ''II''-shaped cover covers the tubular motor. The curtain is a closed-loop-shaped double-side curtain, an upper end is wrapped on the tubular motor, a lower end is wrapped on the curtain vertical shaft and closed loop operation is performed. The curtain has advantages that the closed-loop double-side projection curtain is used to carry out rolling operation; each curtain can display one proportion frame and the double-side curtain can display two proportions of frames; the double-side curtain can be made of one or two kinds of materials; display of most of video sources with different proportions can be satisfied, full screen display without a black edge is achieved and a video effect is increased so that people can comfortably watch and the frame is solid; and when the double-side curtain is made of two kinds of materials, 2D film display and 3D film display can be satisfied. A convenient and economic method is adopted in the invention so that a defect in the prior art is overcome.

Description

[0001] Technical field: [0002] The invention relates to the technology of a projector, and mainly relates to a screen for peripheral products of the projector, in particular to a rolling type double-sided projection screen with different frame specifications and different materials. [0003] Background technique: [0004] Now, the projector has begun to enter thousands of households. There are many aspect ratios displayed by the projector, the mainstream ratios are 16:9, 4:3, 2.35:1, etc. However, the existing projector screen has a certain display ratio when the screen is full, that is, a screen of one display ratio can only display a video of one ratio of the screen. For example, the original black frame of the screen has a ratio of width to height of 16:9, and only the video with a ratio of 16:9 can be displayed in full screen, so that people's vision can get the best and most satisfactory experience. If a 16:9 screen is used to display a 2.35:1 video screen, a horizontal ligh...
