Abstract

The invention discloses a frame-free display device and a joint-free large-screen splicing display system, and relates to the technical field of large-screen splicing display. The frame-free display device comprises a display screen with a frame, and the display area of the display screen includes a central area and fringe areas between the central area and the frame. An optical transparent panel covers in front of a central-area watching surface, and eccentric linear Fresnel lenses cover in the front of fringe-area watching surfaces. The Fresnel center line of each eccentric linear Fresnel lens is near to one side of the central area. The eccentric linear Fresnel lenses used for amplifying the fringe areas are arranged in front of the fringe areas of the display screen with the frame, and the amplified fringe areas are larger than or equal to the frame and completely cover the frame, so that the frame of the display device is eliminated visually.

Description

technical field [0001] The present invention relates to the technical field of large-screen splicing display, and more specifically, to a frameless display device and a large-screen splicing display system that eliminates seams. Background technique [0002] The demand for large-screen display is increasing day by day. Due to the limited size of conventional display devices and the low brightness of large-screen projection in theaters, the application conditions are harsh, and splicing small-sized conventional displays together to achieve super-large-screen display has become a commonly used large-screen display. Screen display mode, and widely used in various occasions, such as traffic monitoring center, power dispatching, subway dispatching and other command, dispatching center, large monitoring room. [0003] There are several solutions for large-screen splicing display, including splicing of LCD, plasma, OLED (Organic Light-Emitting Diode, organic light-emitting diode) a...
