Frame-free internal spherical image displayer

Abstract

The invention discloses a frame-free internal spherical image displayer, and belongs to the field of display technologies and simulation display technologies. The frame-free internal spherical image displayer comprises a displayer body, an inner spherical image amplification guide screen, a lined adhesive, strong double faced adhesive tape and a fixed steel band or non-stretch adhesive tape. The inner spherical image amplification guide screen and imaging glass of the displayer body are bonded together through a wet glass lined adhesive method or a liquid crystal lined adhesive method, and the inner spherical image amplification guide screen and the imaging glass of the displayer body are installed back to an original displayer module again, wherein the inner spherical image amplification guide screen and the imaging glass of the displayer body are fixed together. The inner spherical image amplification guide screen, the imaging glass of the displayer body and an outer frame of the original display module are connected into a whole through the strong double faced adhesive tape and the fixed steel band or the non-stretch adhesive tape. The frame-free internal spherical image displayer can be widely used for film and television display, simulation display, game machine display and other places. The frame-free internal spherical image displayer has the advantages that a narrow-frame two-dimensional displayer is transformed into the frame-free internal spherical displayer which achieves an internal spherical display image and is more suitable for human eye ecology.

Description

technical field [0001] The invention belongs to the field of display technology and simulation display technology, and in particular provides a frameless inner spherical image display, which can be widely used in movie and television display, simulation display, game machine display and other places. Background technique [0002] The inner spherical display surface conforms to the ecology of the human eye, and can restore the visual habit of the human eye to watch the real scene to the greatest extent, and has a wide range of uses in the field of simulation display. How to ensure the simulation of the real scene is the long-term goal of the high-end display industry. Barco Belgium, Christie, and DP UK are leaders in the field of simulation display. Large-scale dome simulation display is basically monopolized by the above three companies. The conventional method is to use six projectors combined with edge fusion to project an inner spherical picture on the inner spherical scr...

Problems solved by technology

The method of using a front projector and a projection screen to display a spherical picture is simple and easy, but the position of the projector needs to be located at the center of the sphere, and the center of the sphere should be the position of the viewer's eyes. There is a contradiction between the two; There is a contradiction that the focal length is difficult to adjust, especially for the inner sphere with a small radius of curvature, it is impossible to obtain a clear image of the entire inner sphere with a conventional transmission screen

Manufacturers such as Samsung, LG, Sharp, Changhong, Skyworth, and Hisense have intensively launched curved TVs, with the aim of pursuing a display effect similar to IMAX theaters. However, slight screen curvature and too small display screens make the immersive effect of curved TVs Big discount, far from the effect of manufacturers' propaganda
