A three-sided viewing intelligent screen for theaters and its construction technology

Abstract

The invention relates to the technical field of cinema screens, in particular to a three-sided viewing intelligent screen for cinemas and its construction technology, which includes a bottom plate arranged on the wall surface of the theater, and two sides of the bottom plate arranged at symmetrical angles and separated from the bottom plate. The side panels connected by seams are equipped with alkali-resistant mesh cloth on the surface of the bottom plate and the surface of the two side panels. The alkali-resistant mesh cloth is coated with a polysand layer for displaying the projected image of the projector. Durable, flame retardant, high sound absorption coefficient, continuous picture, clear picture quality, effectively enhance the viewing experience of the audience.

Description

technical field [0001] The invention relates to the technical field of cinema screens, in particular to a three-sided viewing intelligent screen for cinemas and its construction technology. Background technique [0002] A movie theater is a place where movies are shown for audiences. In the early days of its production, movies were shown in coffee shops, tea houses and other places. With the progress and development of movies, there have been movie theaters specially built for showing movies. The development of movies—from silent to sound and even stereo, from black and white films to color films, from ordinary screens to wide screens to dome screens and ring screens, has greatly changed the shape, size, proportion and acoustic technology of cinemas. [0003] At present, traditional theaters mostly use seats set on a slope, and a screen is set directly in front of the seat. When the audience sits in this kind of theater and watches a movie, only the screen in front will ap...

4. Glass bead curtain: The fabric base is woven from textile threads, and the surface is coated with broken glass beads. It is mainly used to increase the brightness, but the contrast and viewing angle are not good, and the picture quality is worse than other curtains.

[0005] Therefore, in order to ensure the picture quality of the curtains, soft curtains, glass fiber curtains, and woven white plastic curtains all need to use PVC materials, while glass bead curtains do not use PVC materials, but the contrast and viewing angle are not good, and the picture quality is better than other curtains. Poor, cannot be used for theater curtains

[0006] As we all know, PVC material has poor high temperature resistance, and it is easy to deform when working in a hot environment; additives such as heat stabilizers need to be added during processing

The long-term use temperature of most PVC products should not exceed 55°C. It is a relatively unstable polymer and will degrade under the action of light and heat. The long-term projection of the projector will easily cause the temperature of the screen to rise, and it is about 50°C. It will slowly decompose hydrogen chloride gas, which is harmful to the human body. It is easy to soften and relax at high temperature, has poor aging resistance, and becomes hard and brittle at low temperature. Its additives gradually volatilize during use and pollute the air.

[0007] PVC material has no sound-absorbing and flame-retardant effects. When used in theaters, since the theater has multiple projection halls, it will cause noise between the projection halls, and the quietness is poor, which affects the audio-visual independence of each theater and affects the viewing effect.

[0008] At present, there is a three-sided screen. Although the audience's perception has been improved to a certain extent, there are intervals between the three screens, and the displayed picture is not a complete and continuous picture, which still affects the audience's perception.
