Segment Reporting [Abstract] |
Segments | Note 17 — Segments ASC 280, “Segment Reporting”, establishes standards for reporting information about operating segments on a basis consistent with the Company’s internal organizational structure as well as information about geographical areas, business segments and major customers in financial statements for detailing the Company’s business segments. The Company’s chief operating decision maker is the Chief Executive Officer, who reviews the financial information of the separate operating segments when making decisions about allocating resources and assessing the performance of the group. Majority of the Company's business activities are carried out in PRC, hence no geographical segment is disclosed. The Company has determined two operating segments: (1) Holographic solutions, and (2) Holographic technology service. The following tables present summary information by segment for the years ended December 31, 2021, 2022 and 2023:
