Description

Fan display screen

Technical Field

The utility model relates to the technical field of display screens, in particular to a display screen of a fan machine.

Background

Fan-type displays are devices that use the principle that the visual effect produced by the light on the retina remains for a short period of time after the light ceases to be active. When the fan is operated, the lamp beads on the fan blades emit light corresponding to an input image video, and the light received by human eyes stays in a human eye memory staying range along with the rotation of the fan to form a picture. Traditional fan machine display screen adopts the broadcast fretwork picture, and the display screen is arranged in apart from ground a take the altitude, and the fretwork picture of broadcast is hung in the air, gives the impression of aerial formation of image, and it has following shortcoming:

the playing stereoscopic effect is poor: the existing fan display screen only depends on the effect of suspended in the air generated by hollowing out the picture, thereby providing people with stereoscopic impression, which is still not obvious and has no depth of field effect.

The playing object is single; a certain stereoscopic effect can be generated only when a special 3D video with hollowing out is played (only people or objects, no scene or background, or black scene or background in the picture). Hollow videos are rarely seen and used at ordinary times; although the existing 3D rotating fan machine can also play non-hollow conventional images and videos, the played pictures have no three-dimensional effect, so that the value of the played pictures is lost.

The application scene is single; the application range is extremely narrow, only a small amount of the product is used in the field of stage decoration or advertisement display, and the product is difficult to apply to the fields of families, offices, VR and the like and is difficult to popularize and apply.

The above disadvantages are mainly caused by their own structure and the corresponding structure of the display and play method, and if the above disadvantages are to be overcome, improvements are needed from the structure and the display and play method.
