Rotation display apparatus based on direct current motor

Abstract

The invention discloses a rotation display apparatus based on a direct current motor. The rotation display apparatus based on a direct current motor includes a display module, a transfer bar, a shaft joint and a motor, wherein the display module is arranged at the top, and is connected with the motor at the bottom through the transfer bar and the shaft joint. The rotation display apparatus based on a direct current motor has the advantages that the rotation display apparatus based on a direct current motor realizes that the motor drives the model embedded with LED to rotate, and displays patterns of a world map and a map of China; the lithium battery, the motor, pcb and the STM32 control panel are integrated into one body, and the appearance is decorated exquisitely; the rotation display apparatus based on a direct current motor enables people to view images without dead zone in an omnibearing manner; compared with a traditional LED display screen, the rotation display apparatus based on a direct current motor utilizes less LED and IO interface to realize complicated images, and becomes simpler in hardware connection and is not complicated in technology; and the rotation display apparatus based on a direct current motor has significant teaching meaning, and can be applied to teaching devices and the like.

Description

technical field [0001] The invention relates to the field of display and electronic technology, in particular to a rotating display device based on a direct current motor. Background technique [0002] Persistence of vision, that is, when the human eye is observing the scene, the light signal is transmitted to the brain nerve, and it takes a short period of time. After the effect of light is over, the visual image does not disappear immediately. caused by a time value of one-twenty-fourth of a second. The demand for information publicity in modern society is very large. Electronic advertising has covered all aspects of people's daily life and has become an indispensable part of life. The simpler and novel way of information transmission will undoubtedly bring people a refreshing experience. feel. [0003] At present, the vast majority of LED flat screens that people see are composed of small LED module panels, which adopt dynamic scanning and are divided into 8-line scanni...

Problems solved by technology

The advantages of this kind of LED display are high brightness, long life, large viewing angle, easy interface with computer, rich supporting software, etc. However, with the development of economy, the traditional LED display can no longer meet the growing needs of people. In the following aspects: 1. The entire display area of ​​the traditional display screen is composed of LEDs, the hardware connection is complicated, the number of devices is large, and the cost is high; 2. Since the display screen is a plane, there is a certain viewing angle limitation; 3. The traditional display screen The picture is monotonous and unattractive, which is easy to cause aesthetic fatigue
