Problems solved by technology

[0003] The fan screens in the prior art are usually displayed by a single unit. Since the size of a single unit is limited, the display effect is single. If the fan blade size of a single fan screen is increased, the edge resolution will be significantly reduced. There are also some combined fan screens that simply piece together multiple fan screens, and there will be relatively large black shadows at the edges of the display screens of adjacent fan screens, which affects its display effect

Abstract

The invention discloses a fan screen tiled display system and a method for eliminating overlapped black shadows thereof. The fan screen tiled display system comprises a plurality of fan screens, and display areas of every two adjacent fan screens are not on the same plane and are partially overlapped when the two adjacent fan screens rotate to display. Each fan screen comprises a driving motor, a rotating disc arranged on an output shaft of the driving motor and fan blades arranged on the rotating disc. A control panel is arranged in each rotating disc, and a row of LED lamp beads are arranged in the middle of the upper surface of each fan blade. The fan blades are arranged to be in a long strip shape, symmetrical notches are formed in the two sides of the outer end portions of the fan blades, the torsional angle of the fan blades is reduced, and the front end portions of the notches are obliquely arranged outwards. The symmetrical notches are formed in the two sides of the outer ends of the fan blades, so that the overlapping area and the torsional angle of the two fan blades are reduced, the problem that black shadows are generated at the edge of a picture displayed by the fan screens is solved by reducing the torsional angle, and the display effect is improved.

Description

technical field [0001] The invention relates to the technical field of fan screen display, in particular to a fan screen splicing display system and a method for eliminating overlapping black shadows. Background technique [0002] The fan screen uses the persistence of vision effect to display 3D images, so the 3D images displayed by the fan screen can be seen directly through the naked eye without the need for other auxiliary equipment. [0003] The fan screens in the prior art are usually displayed by a single unit. Since the size of a single unit is limited, the display effect is single. If the fan blade size of a single fan screen is increased, the edge resolution will be significantly reduced. There are also some combined fan screens that simply piece together multiple fan screens, and there will be relatively large black shadows at the edges of the display screens of adjacent fan screens, which affects its display effect. [0004] Therefore, the prior art still needs ...
