Rolling-type double-side projection curtain

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...

Problems solved by technology

[0005] Another problem is about the material of the curtain. Existing curtains include fiberglass curtains, white plastic curtains, metal curtains, etc. A curtain can only be made of a certain material, and curtains of different materials are only suitable for displaying a certain For example, when a projector displays 2D images, the glass fiber screen is the best, and when the projector displays 3D images, the metal screen is the best. One screen cannot be suitable for both 2D and 3D display. There are also restrictions on different screen displays
