Description
Technical field
The present invention relates to LED display technical field, more specifically, particularly to a kind of rotary LED display screen.
Background technology
LED display is widely used to the public places such as advertisement, station, bank, market, and it has the advantages such as power consumption is little, life-span length, color are good.The luminescent device of existing LED display mainly uses LED flat plate module, such display screen mainly to have two problems to have much room for improvement: being first that whole display screen is made up of LED module entirely, number of devices is many, and cost is high；Further, since display screen is a plane, LED picture element has certain visual angle to limit simultaneously, makes the visual range of display screen be confined to front within the scope of certain, makes the information of display screen issue in the application and receives certain space and limit.
Rotary LED display screen solves the problems referred to above, but the universal structure of existing rotary LED display screen is motor and rotates pillar display screen.The principle of this rotation sweep: owing to human eye has the characteristic of persistence of vision, when picture refreshes with given pace, we have seen that is exactly continuous print image, television set display uses point by point scanning mode, wants refresh picture 50 (25 frame) each second, is then the picture that a width is complete in human eye, tradition LED display typically uses 1/16 scanning, 16 row circulate line by line to be lighted, owing to refresh rate is sufficiently large, it is seen that be also the picture of a web stabilization.Its principle is illustrated as it is shown in figure 1, wherein (a), (b), (c), (d), (e) are display state the most in the same time respectively, and (f) is the complete picture " 3 " that people arrives soon.In this LED display, using transposition line by line and moving down the scan mode lighting device, must there be light-emitting diode display part each provisional capital, and this just makes the cost of display screen bigger than normal.
Rotary scanning mode display only has string, by driven by motor, it rotates, the state of this position is just shown when running to a certain position, the state of the next position is shown again after the next position, the i.e. display of string display device all images to be completed, scanning process is changed position by mechanical rotation and is realized.Its displaying principle is as shown in Figure 2.Figure a) b) c) is display state the most in the same time, d) is the complete picture " 3 " seen of human eye.
In the design process, center of gravity regulation is a most difficult sport technique segment to rotary LED display screen, and the center of gravity of rotation is directly connected to stable operation and the safety issue of system.If the center of gravity rotated is not in rotating shaft, in rotation at a high speed, violent shake can be produced, under huge centrifugal force, whole system can be made to decompose, produce potential safety hazard.Commonly used in prior art is discoidal circuit board, but, due to the encapsulation of electronic device, weight is all different, and the center of gravity of disk circuit board is uneven distribution, relatively difficult regulation.For this reason, it is necessary to design a kind of improvement, the rotary LED display screen that center of gravity is more stable can be made.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the rotary LED display screen that center of gravity is more stable can be made.
In order to achieve the above object, the technical solution used in the present invention is as follows:
A kind of rotary LED display screen, pillar display screen is rotated including LED, rectangular circuit board, rotating shaft and motor, described LED rotates pillar display screen and is located at the middle position of rectangular circuit board, described motor is connected with the bottom of rectangular circuit board by rotating shaft, it is packaged with LED drive module in the side of described rectangular circuit board, opposite side in described rectangular circuit board is packaged with the second microcontroller and the second wireless transceiver, interconnective first microcontroller and the first wireless transceiver it is provided with in the side of described motor, wherein said first wireless transceiver and the second wireless transceiver wireless connections, described second wireless transceiver and the second microcontroller connect, described second microcontroller is connected with LED drive module, described LED drive module rotates pillar display screen with LED and is connected；And second the weight sum of microcontroller and the second wireless transceiver be multiplied by rotating shaft to the distance of rectangular circuit board one end and be multiplied by rotating shaft to the distance of the rectangular circuit board other end equal to the weight of LED drive module.
Further, described first microcontroller and the first wireless transceiver are encapsulated in a circuit board.
Further, described circuit board 8 is additionally provided with the keyboard being connected with the first microcontroller.
Compared with prior art, it is an advantage of the current invention that: the present invention uses rectangular circuit board, when circuit-board laying-out, can conveniently ensure the rotating shaft position of centre of gravity just to rectangular circuit board, it is to avoid produce rotation when rotated, make rotation more stable.
