Abstract
The present invention discloses the LED rotational display scheme of a kind of compact-sized, high-res, low jitter sense, the displaying scheme mainly includes odd-even symmetry type LED light column, LED light column are specifically rendered as left and right sides central symmetry layout, alternating expression symmetric configuration above and below simultaneously, it is realized LED layout in long and narrow PCB elongated plates with this, with save the cost, reduce volume, the display resolution doubled simultaneously, and substantially avoided the flating sense generated by left and right sides interlaced display, the design greatly improves the display effect of more spiral arm fan-shaped rotary displays.
Description
Technical field
The present invention relates to a kind of high-res low jitter sense fan-shaped rotary displays, and specially one kind can be as fan
High-speed rotating light-emitting LED lamp bar forms the plane fan type display device of image using the persistence of vision principle of human eye.
Background technique
Rotating display device be it is a kind of persist principle using human eye vision, high speed rotation LED light column, by different positions
Make LED fast blink, to form a kind of equipment of image.
If shooting rotating display device using high speed camera, it is found that complete image seen by person is only to appoint in fact
Meaning moment LED light is arranged according to formula fast blink and is formed；There are many form, such as cylindrical, balls for common rotating display device
The revolving bodies such as shape, sector；Related product is more both at home and abroad at present, and TaiWan, China has the production of related high-end product to look forward to Germany
Industry, such high-end product are usually mainly advertising display using field based on the cylinder of high-res.
In the prior art, it generally shows that resolution is lower, and shows that resolution is mainly limited by LED size itself,
The full-color type LED smaller size that can be selected at present under normal circumstances is 1.6mmX1.6mm or so namely minimum pixel gap is
1.6mm or so, if it is considered that the gap LED, then pel spacing is generally higher than 1.6mm.
Best design scheme is using single-row left and right complementary type LED placement scheme namely the left side in existing main product
Single-row LED shows that odd-line pixels, the single-row LED in the right show even rows, and left and right sides LED lamp bead is just interlocked,
Display precision can be improved；However this design scheme, the biggest problems are that when showing image, previous frame and next frame image are simultaneously
It is not overlapped, so that dizzy flating sense is made us in generation, therefore, such design method is to sacrifice display effect and exchange display for
The half-way house of precision, display effect are bad.
Summary of the invention
The object of the invention is that solve the above problems, and provide it is a kind of it is compact-sized, display effect is good, low in cost
Fan-shaped rotary displaying scheme.
The present invention is through the following technical solutions to achieve the above objectives: a kind of high-res low jitter sense fan-shaped rotary is shown
Device, including main left and right central symmetry, upper and lower odd-even symmetry type LED light column.
Integral LED lamp column are rendered as left and right sides central symmetry layout, while alternating expression symmetric configuration up and down.
Upper and lower LED light column alternating expression distribution, realizes two particularly important purposes of design with this: 1, LED being laid out narrow
In long PCB elongated plates, with save the cost, reduce volume.2, LED is interlaced, with the display resolution doubled, together
When bilateral symmetry substantially avoided the flating sense generated because the left and right sides interlocks therefore under same rotational speed.
System must finely tune display formula, so that the LED light column of different angles realize coincideing for image.
For the fan-shaped rotary display of four or eight spiral arms, the design still has evident from advantageous effect.
Detailed description of the invention
Fig. 1 is LED light layout structure schematic diagram provided in an embodiment of the present invention；In figure: 1, filling out black region as LED light column；
2, PCB circuit board carrier；Partial enlarged view can with reference to auxiliary line see LED lamp bead specifically interlock layout method.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without making creative work it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
Referring to FIG. 1, being a kind of high-res provided in an embodiment of the present invention, low jitter sense fan-shaped rotary display, packet
Include main odd-even symmetry type LED light column.
LED light column are rendered as left and right sides central symmetry, while alternating expression symmetric configuration up and down.
Upper and lower LED light column are just interlaced, meet two important purposes of design with this: 1, LED layout is long and narrow
In PCB elongated plates, with save the cost, reduce volume.2, LED is interlaced, with the display resolution doubled, and meanwhile it is left
Right central symmetry, therefore under same rotational speed, it substantially avoided the flating sense generated because the left and right sides interlocks.
System must finely tune display formula, so that the LED light column of different angles realize coincideing for image.
For more cantilever fan-shaped rotary displays of two or more spiral arms, the design equally has apparent display effect excellent
Gesture.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the embodiments can also be by appropriately combined, formation those skilled in the art
The other embodiments that member is understood that.
