In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Example 1

Referring to Fig. 1, a display stand for ideological and political propaganda, the display stand includes a frame body, the frame body can be installed on any wall or screen to form a display screen, and 4 miniature projectors 1 are arranged on the frame body, the miniature The projector 1 is arranged on the frame body, and the installation position can be changed. The micro-projector 1 is connected to a single-chip microcomputer 4 through the data line 2. The single-chip microcomputer 4 is connected with a button module 5 and a display module 6. The single-chip microcomputer 4 accepts external data. data transmission interface. The data transmission interface is USB interface 3. Frame body is made up of soft flexible rope 7 that can be rolled. It can be fixed on a certain wall at will, and by adjusting the position of the micro-projector 1, the range of display can be divided into areas, and the space can be divided into four areas. As shown in Figure 1, the four micro-projectors 1 are respectively placed The two on the upper side are one-level symmetrical and the two on the lower side. This display stand transmits the displayed pictures to the single-chip microcomputer 4 through the USB interface 3, adjusts the displayed content through the button module 5 and the display module 6, and connects the micro-projector 1 to the micro-projector through the single-chip microcomputer 4. The projection display on the wall makes it easy to replace the displayed content, and the entire device is easy to install. Because it is software, the display space can be freely controlled.

Example 2

Referring to FIG. 2 , the difference from Embodiment 1 is that the frame body is composed of telescopic rods 8 . The display stand includes a solar panel 10, the solar panel 10 is connected to a storage battery 9, and the micro projector 1 and the single-chip microcomputer are powered by the storage battery. In this embodiment, the telescopic rod 8 can be used as a slideway, and the micro-projector 1 is sleeved on the slideway, and can be slid and fixed at will.
