Abstract

The invention relates to a magnetic display device. The magnetic display device comprises a magnetic display board, a plurality of magnetic particles, a printing head, a first drive device and a control device, wherein the magnetic display board is fixedly connected to a rack; the plurality of magnetic particles fill the magnetic display board and can move freely in the magnetic display board; the printing head is arranged on one side of the magnetic display board, one end of the printing head has magnetism, the printing head is arranged corresponding to the magnetic display board, and thus the magnetic particles, close to the printing head, in the magnetic display board can be attracted; the first drive device is fixedly connected to the rack, and drives the printing head to move along the surface of the magnetic display board; and the control device controls the first drive device to act. The invention further relates to a magnetic display method. The first drive device drives the printing head to move along the surface of the magnetic display board, one end of the printing head has magnetism, so that the magnetic particles inside the magnetic display board are attracted to swing to the surface of the magnetic display board, thus the content needing to the displayed is formed, the needed display content can be updated immediately, and the updating is convenient and rapid.

Description

technical field [0001] The invention relates to the field of advertisement display, in particular to a magnetic display device and a display method. Background technique [0002] In order to achieve the purpose of advertising, billboards are placed beside many shops and bus stops. Billboards can attract customers to a certain extent and bring potential business opportunities for businesses. [0003] Usual billboards are generally packaged with plexiglass or endurance boards, and oil canvas or silk cloth printed with specified patterns are installed inside the billboards. This kind of advertising board has the problems of cumbersome installation and replacement, and the inability to update the displayed content in real time. [0004] Now there are magnetic billboards using magnetic materials on the market. The principle is to use ferrous surface materials to replace the original adhesive car stickers. After the ferrous surface materials with patterns are produced, they are a...
