然而,習知的該顯示系統1存在以下問題:(1)主機10及顯示裝置12間每增加一種傳輸格式(如視訊、音源、通用序列匯流排),就需另外鋪設一條對應該傳輸格式的傳輸線,不僅增加傳輸線鋪設成本,亦造成該主機10及該顯示裝置12間的連接線路過於複雜,而難以管理。(2)一般傳輸線的有效距離過短(如通用序列匯流排傳輸線及高解析多媒體介面(High Definition Multimedia Interface,HDMI)傳輸線的有效距離皆僅有5公尺),而使得該主機10及該顯示裝置12間的設置距離上限受限於傳輸線有效距離而過短。(3)習知的該顯示裝置12需外接該電源16方可取得運作所需電力,而使得該顯示裝置12的設置位置受到該電源16所在位置的限制。 However, the conventional display system 1 has the following problems: (1) For each additional transmission format (such as video, audio source, and universal serial bus) between the host 10 and the display device 12, an additional transmission format is required. The transmission line not only increases the cost of laying the transmission line, but also causes the connection line between the host 10 and the display device 12 to be too complicated and difficult to manage. (2) The effective distance of the general transmission line is too short (such as the universal serial bus transmission line and the high resolution multimedia interface (HDMI) transmission line are only 5 meters effective distance), so that the host 10 and the display The upper limit of the set distance between the devices 12 is limited to the effective distance of the transmission line and is too short. (3) The conventional display device 12 needs to externally connect the power source 16 to obtain power required for operation, so that the setting position of the display device 12 is limited by the position of the power source 16.
