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

Embodiment Construction

[0061] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] The current display screens include flat screens, ring screens and dome screens. Among them, the flat screen means that the screen is flat, usually rectangular; the ring screen means a ring-shaped screen with a certain height; Spherical screen. In practical applications, based on cost considerations, the length and width of the flat scree...

Abstract

The embodiment of the invention discloses a display screen. The display screen is of a totally closed or partially enclosed shell structure, wherein the internal part of the shell structure is used for providing continuous images at viewing angles of 180-360 degrees in a horizontal direction; the shell structure comprises a cylindrical part; the side wall of the cylindrical part is arranged in a smooth arc or a straight line in an axial section; and when the side wall of the cylindrical part is arranged in the arc, the radius of a circle corresponding to the arc is greater than the maximum vertical distance from the arc to the axis. According to the display screen, the targets of making the audience watch comfortably and reducing the cost are achieved on the basis of meeting relatively strong 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...
