The difference between logo and signboard:

A "signboard" is a sign hung in front of a store as a sign. Signboards have a long history in our country, and the signboards themselves are valuable intangible assets on which business operations depend. With the development of the economy, the scope of signboards in today's society has expanded. For example, the appearance of corporate buildings, light boxes, and neon lights are all forms of signboards, and companies can often use signboards to achieve the purpose of advertising.

Logo is a legal concept, which emphasizes the protection of the legitimate rights and interests of producers and operators. Trademarks in my country are divided into "registered trademarks" and "unregistered trademarks". A "brand" can be a registered trademark or an unregistered trademark.

A logo can be said to be a trademark. A signboard is a brand used to attract customers and display store products to customers. The main function of signage is to indicate and guide directions.
