Theaters were feeling newly optimistic, largely because “ Top Gun: Maverick” and several other blockbusters showed that people still want to go to the movies. In recent months, the situation didn’t look so dire. Now, staggering debt and a severe shortage of big movies to show in the months ahead imperil multiplex chains once again. Unwelcome forces - Netflix, 50-inch TVs, the coronavirus pandemic - have buffeted cinemas for years. On a torex screen, light from the projector should hit all parts of the screen at the same time.The hits just keep on coming. Not only do they curve in at each end, they also curve in at the top and bottom of the screen creating a concave surface. Torex screens take this idea to the next step. This is how you see a movie projected onto a horizontal-curve screen.īy curving the ends of the screen towards the projector, the distance traveled by the light can be equalized. This is how you see a movie projected onto a flat screen. The diagram below demonstrates this concept: Since the size of the projected image is determined by the distance to the screen, this makes the image appear slightly larger towards each end. On a flat screen, light from the projector travels a shorter distance to reach the middle of the screen than it does to reach the edge of the screen. Pincushioning describes the distortion of the image on the screen by the changes in distance of the light from the projector. This curving is to avoid the pincushion effect, particularly in auditoriums with a short distance from the projector to the screen. Horizontal-curve screens curve toward the audience slightly at each end. The three choices are:Ī flat screen is just that, a screen with no curve at all. In addition to the amount of reflectivity, a theater owner has to choose the curve of the screen. This makes for a more immersing movie experience. The audio is delivered through the appropriate speaker so that a sound seems to come from the person or thing talking or making noise. This makes the sound seem more realistic, particularly when someone is talking. In a typical theater, you'll find three speakers behind the screen, located at the far left, center and far right. Most movie screens have tiny perforations in them so the audience will be able to hear speakers placed behind the screen. Movie screens are designed not only to present a great picture, but also to support the theater sound system. A glass bead screen actually has thousands of tiny glass marbles embedded in a transparent coating on the surface of the screen. To make a pearlescent or silver screen, a reflective coating is added to the matte white vinyl. Pearlescent is probably the most common choice for a typical movie theater. Glass bead: 40 percent or more reflectivity, black is light gray and image is usually too bright, normally used only under special circumstances.Silver: 30 percent reflectivity, black is medium gray and image is very bright, dark colors can seem a little dull.Pearlescent: 15 percent reflectivity, black is dark gray and image is bright, provides best overall contrast.Matte white:
