Background In the broadcasting field, the prompter equipment is a key tool for guaranteeing broadcasting quality whether the traditional television broadcasting, the live event host, the emerging network live broadcast, the outdoor interview and other scenes are adopted. Along with the increasing of outdoor broadcasting activities, such as outdoor news live broadcasting, large-scale sports and event explanation, outdoor cultural activities hosting and the like, the limitations of the traditional prompter equipment in the outdoor complex environment are more and more remarkable, and the requirements of high efficiency and flexibility of modern broadcasting cannot be met. The traditional prompter mainly adopts display modes such as an LCD screen or a projector. In outdoor environment, strong light irradiation can cause severe reflection of the screen, so that text display is blurred, and a broadcaster is difficult to accurately read contents, and in night or low-light environment, text is difficult to identify due to insufficient screen brightness. For example, in the field of direct sunlight outdoor news live broadcasting in noon, the screen of a traditional prompter often cannot provide clear prompter information due to light reflection, so that normal play of a broadcaster is affected. Moreover, conventional prompters are usually fixed devices, which need to be installed at specific locations and cannot be flexibly adjusted following the movements of the broadcaster. In outdoor broadcast scenes, a broadcaster may need to walk, turn around, or interact with the audience, etc., and a stationary prompter may not meet such dynamic needs.
