Abstract

A sector display, in which display is achieved by using the persistence of vision in the human eye of a rotating point light source.

Description

Sector display

Field of invention

The invention relates to a sector display, in particular to a device that realizes display of the visual residue of human eyes by using a rotating point light source.

Background technique

There are some spherical LED displays on the market, which are fixed indoors or outdoors through brackets or suspension cables to display images of the earth. Among them, the LED light source is fixed or rotating. The latter uses the rotating LED point light source to leave the human eye's vision. When the LED point light source moves to a specific position, it turns on or off, so as to achieve the equivalent of ordinary display pixel point lighting. Or turn off the effect.

Summary of the invention

It is conceivable to embed multiple point light sources in the string, and then make one end of the string rotate around the other end. According to the instruction, when the point light source is rotated to a specific position to turn on or off, the visual residue of the human eye can be used to form the image that needs to be displayed. If the string rotates once, the display surface is a circle, and if it is less than one revolution, it is a sector. For continuous display, when the display surface is a sector, the chord turns to the boundary of the sector and then returns.

However, it should be understood that the content of the present invention may not include all aspects and embodiments of the present invention. The content of the present invention is not meant to be restricted or restricted in any way, and the present invention disclosed herein will be understood by one of the following: The technical staff includes obvious improvements and modifications.

Detailed ways

The present invention will now be described more fully hereinafter. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Hopefully, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

It should be understood that various changes can be made to the function and arrangement of elements without departing from the spirit and scope set forth in the appended claims. Therefore, the embodiments are examples or implementations of the present invention, rather than the only implementations. The various appearances of "one embodiment," "an embodiment," or "some embodiments" do not necessarily all refer to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may also be provided individually or in any suitable combination. Conversely, although the invention may be described herein in the context of separate embodiments for the sake of clarity, the invention may also be implemented in a single embodiment or any combination of embodiments.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of related technologies and the present disclosure, and will not be interpreted as idealized or excessive The formal meaning, unless explicitly defined as such in this article.

Reference terms such as "left", "right", "upper", "lower", "front" and "rear" are intended to be used in the implementation of the present invention in relation to the specific features, structures or elements in the depicted embodiment example. Obviously, such directional terms regarding the actual use of the device have no specific meaning, because the device can be used by a user or multiple users in multiple directions.

The embodiment of the present invention mainly describes a display device based on a circular surface and a sector surface. However, the embodiment of the present invention is not limited to the circular surface and the sector surface. For example, by adjusting the length of the string during rotation, it is also possible to form a display surface of other shapes.

For example, through the mechanical structure at the center of the circle, or the electromagnetic field makes the line segment of the point light source move up and down through the center of the circle while rotating along the line where it is. When the chord turns perpendicular to the horizontal plane, the chord is the shortest, and when the chord turns 45° or 135° to the horizontal plane, it is the longest. In this way, the point light source can cover a rectangle.

In addition, multiple such devices can also be used to form a larger display surface. In this fan display group, the above-mentioned complicated structure can be avoided. Simple fan displays can avoid collisions with each other. This can be achieved by carefully designing the rotation speed and starting position. If there is a power failure, a locking mechanism can also be designed to avoid equipment damage. Or attach a battery to ensure that it can safely stop rotating to avoid collisions after power failure.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Various changes and modifications according to the claims and specification of the present disclosure are still within the scope of the claimed invention. In addition, each embodiment and claims may not include all the disclosed advantages or special tightening mechanical clamping properties. In addition, the abstract and title are only used to facilitate searching of patent documents and are not intended to limit the scope of the claimed invention in any way.
