Description

Technical Field

[0001] The present invention relates to the technical field of news dissemination, and in particular to a multi-angle display device for news dissemination. Background Art

[0002] News, also known as information, refers to the information disseminated through media channels such as newspapers, radio stations, broadcasts, and television stations. It is a genre that records society, disseminates information, and reflects the times. The concept of news can be divided into broad and narrow meanings. In a broad sense, all commonly used texts except comments and special articles published in newspapers, broadcasts, the Internet, and television belong to the category of news. News is a major way for people in today's society to obtain information.

[0003] In some science and technology exhibition halls, display screens are usually used to disseminate and display news content. Visitors can choose the news content they are interested in on the display screen to watch, but the display screens used for display are generally mounted on the wall. For the display screens on the wall, visitors with shorter height cannot use the display screens to select news content. Some display screens are fixedly installed horizontally or tilted on the display table, but visitors need to keep their heads down to watch when using them, and taller people even need to bend down to operate the display screens when using them.

[0004] Most display screens are fixedly installed and can basically only face one side for display. The angle and height cannot be adjusted. The one-way display area is limited and there are limitations in use. Moreover, when there are a large number of visitors, if there are visitors in front of the display screen using it, other visitors will not be able to directly see the content on the display screen.

[0005] In addition, most of the current display screens are touch-sensitive, and are operated by directly touching the icons and buttons on the screen. However, after being used by most people, sweat, fingerprints, dust stains, etc. will be left on the display screen, which will affect the display and viewing.

[0006] Therefore, based on the defects of the prior art, the present invention provides a multi-angle display device for news dissemination to solve the above problems. Summary of the invention
