[0002] Currently, existing display screen devices face numerous technical bottlenecks in practical applications. On the one hand, their environmental adaptability is poor. Under different ambient light intensities, color temperatures, and noise conditions, they struggle to automatically adjust display and sound field parameters, resulting in a poor user viewing experience. On the other hand, they lack efficient self-cleaning mechanisms, making it easy for dust to accumulate on the surface of the display screen, affecting display quality. Furthermore, manual cleaning is costly and inefficient. Additionally, the heat dissipation systems of existing devices are mostly fixed, unable to dynamically adjust heat dissipation strategies in real time based on device temperature, potentially leading to overheating and impacting lifespan and performance stability. Moreover, the correlation between display quality and user distance is insufficiently considered, failing to adaptively adjust display parameters based on the distance between the user and the screen, making it difficult to meet the needs of different usage scenarios.
