Description

Outdoor publicity display device

technical field

The invention relates to the field of publicity and display, in particular to an outdoor publicity and display device.

Background technique

Propaganda, a term in communication science, is an information presentation method specially designed to serve specific issues, and its significance lies in the process. In foreign languages, propaganda originally meant the dissemination of philosophical arguments or insights, but is now most often used in political contexts, especially to refer to operations supported by governments or political groups. When the same technique is used for a business or product, it is often referred to as PR or advertising. A social behavior that uses various symbols to spread certain concepts to influence people's thoughts and actions. Propaganda and its activities have a long history in the history of human civilization. In my country, there is a sentence in "Three Kingdoms, Shu Zhi, Pengyi's Biography" written by Western Jin historian Chen Shou, "Mr. is also surprised, several orders Yi to promote military affairs, instruct generals, and envoys to praise", it can be seen that in the last years of the Eastern Han Dynasty in China, "proclamation" has been put into practice. ” and “biography” are used together.

Propaganda display is to effectively convey a certain information to the person receiving the information, so that the person receiving the information can receive the information. At present, the conventional form of publicity and display is advertising, that is, advertising for publicity. With the development of science and technology, the way of publicity and display has changed from the earliest pictures to the current videos.
