[0002] Information presentation usually refers to the process of presenting information to the audience in a clear, intuitive and easy-to-understand way through various media or tools. In the financial analysis of enterprises, the use of devices for information presentation is a key step to ensure that the analysis results are effectively communicated and applied. Financial analysis is a method of evaluating the financial status and operating results of an enterprise. It reveals the financial health and operating efficiency of an enterprise by deeply interpreting the data in the company's financial statements. It is not only an important tool for internal management of an enterprise, but also a key way to convey corporate value to external investors, creditors and other stakeholders. The importance of financial analysis is reflected in many aspects: first, it helps corporate management understand the company's financial performance and make more informed business decisions; second, it can enhance the company's risk management capabilities, prevent and discover potential risks; third, it is a tool for external communication of enterprises, which helps to build trust between enterprises and external stakeholders. Financial analysis mainly uses several basic methods, including comparative analysis, ratio analysis and trend analysis, which can help analysts understand how the company's financial status changes over time and how it performs compared with other companies in the industry.

[0003] The patent document with announcement number CN219243185U discloses an information display platform with financial analysis, including a base, a center column fixedly connected to the middle position of the upper end of the base, an installation cavity is provided on the inner side of the center column, a stretching component is installed on the inner side of the installation cavity, and a first damping shaft is installed on both the front and rear ends of the center column. The message display platform can flexibly control the rotation of the support arm by using the stretching component, thereby effectively playing the role of folding the platform.

[0004] In the appealed patent, a display component that can be stored is provided to reduce the space occupied.
