a display screen

Abstract

The embodiment of the invention discloses a display screen. The display screen is of a totally-enclosed or partially-enclosed shell structure, and the internal part of the shell structure is used for providing continuous images with the view angle being 180-360 degrees in the horizontal direction. The shell structure comprises a cylindrical portion, wherein the side wall of the cylindrical portion is arranged in a smooth arc line or straight line mode on the axial cross section. When the side wall of the cylindrical portion is arranged in the arc line mode on the axial cross section, the radius of a circle corresponding to the arc line is greater than the maximum vertical distance between the arc line and an axis. The display screen disclosed by the invention realizes the purposes that the audience are comfortable in watch and that the cost is reduced on the basis of meeting a requirement of high immersion of the audience.

Description

technical field [0001] The invention relates to the display field, in particular to a display screen. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The development trend of human information communication technology is to continuously reduce the value of information entropy, and finally make the value of information entropy close to zero, that is, to reproduce the real world as realistically as possible. Since the appearance of movies, display screens have been constantly changing, improving, and updating. [0004] According to the shape of the screen, the display screens in the prior art can be roughly divided into flat screens, ring screens and ball screens. "High Presence Display" (ISBN: 7030110218, (Japan) Tani Chitsu) proposed that several elements of high telep...

Problems solved by technology

[0007] The dome screen mentioned in the background technology, including the dome screen in the patent document, has the advantage of making the audience feel more immersive, but in practical applications, since the seats of the audience are arranged in rows, the distance between sitting in the middle position Viewers on both sides farther away see a higher inclination of the dome screen when viewed horizontally, which does not conform to the normal viewing angle of the human eye, resulting in uncomfortable viewing

And if you want to ensure that the audience on the side can also watch comfortably, you need the dome to have a larger diameter, so the cost of manufacturing the dome is higher
