Projectors have a wide range of application scenarios, covering household entertainment, commercial office, education and teaching, and professional public display fields, meeting the large-screen display needs of different groups. In household scenarios, projectors have become the core equipment of home theaters, replacing traditional TVs to create an immersive viewing experience. Families can use projectors to watch movies, TV dramas and live sports events, and the large-screen picture of up to 300 inches brings a stronger sense of immersion than ordinary TVs. In addition, it can also be used for parent-child education, children's animation viewing and family video watching, with flexible screen size adjustment to adapt to different family entertainment and learning needs, and it also saves indoor space compared with large-size TVs.

In commercial office scenarios, projectors are indispensable auxiliary equipment for enterprise meetings and business demonstrations. In daily office meetings, employees can connect computers, mobile phones and other devices through wired or wireless ways to project PPT, data reports and project videos, making the meeting content more intuitive and clear, and improving communication efficiency. For enterprise publicity and product display, projectors can be used in exhibition halls and reception rooms to play enterprise introduction videos and product promotion materials, helping customers quickly understand enterprise strength and product advantages. The portable projector can also be carried for external business negotiations and temporary roadshow displays, realizing mobile office display.

In the field of education and teaching, projectors are widely used in kindergartens, primary and secondary schools, and university classrooms. Teachers can project teaching courseware, experimental videos and graphic materials, transforming traditional blackboard writing teaching into diversified multimedia teaching, which enriches teaching forms and stimulates students' learning interest. In addition, projectors are also used in training institutions for professional skill training and academic lectures, realizing large-scale synchronous display of teaching content. In professional scenarios such as outdoor camping, private screening rooms and party gatherings, portable projectors can also be used to build temporary projection screens, meeting the diverse display needs of leisure and entertainment activities.
