In the last two decades, various exhibitions were held in museums in Taiwan; however, studies on displays are quite rare and not very profound. As a result, the research aimed to investigate and analyze the transition and the influence of museum panels which are often ignored in the exhibitions, yet the most basic display medium which helps audiences to understand the displayed objects. In particular, after the technical development of computer graphics, the roles of panels continue to change. By focusing on the underlying theoretical concepts, the existing functions and roles of panels are reviewed. Taking the permanent and special exhibitions held at the National Science & Technology Museum (NSTM) as an example, the researcher aimed to explore the transformation and impact caused by evolving computer technology on the displayed objects. Content analysis was applied to observe, analyze and compare the present and past panel changes. After conducting an in-depth interview with the senior staff members who are in charge of exhibitions, the researcher noticed that qualitative changes occurred in the process of producing the panels, as well as their appearance and the functional roles after implementing computer graphics and information technology. The effect of panels employing computer graphics is to give them greater clarity and substance. They are now easier to make and can be made promptly. Their appearance has been transformed from one color to a multi-colored design. While the changes have brought a different atmosphere to the museum, the traditional roles, such as describing the displayed objects, are still maintained. In the past, panels were motionless and fairly boring for audiences who had no interest in reading the explanations. But now the panels incorporating computer graphics are vivid and interesting. The atmosphere in the museum is now totally different from that in the past.
