電子看板所使用的電子顯示裝置不斷發展與進步，消費者開始對於大螢幕顯示的需求越來越多，且要求的看板尺寸通常遠超過目前商用大尺寸面板，因此產生了螢幕拼接需求。本研究採用軟硬體共同設計實現了一個拼接式電子看板系統，透過雲端的電子看板媒體內容管理，連結至終端Android嵌入式平台的媒體播放器，播放的視訊被切割傳送至FPGA平台上的快速影像插補器。每一個插補器對切割視訊進行影像放大並顯示在獨立的LCD，完成LCD拼接顯示。最後我們完成電子看板軟硬體整合驗證和實驗，其性能可達16.2 Frames/sec VGA格式的播放。本研究所提出的方法和系統架構可以降低LCD拼接的系統建置成本，並且提高拼接後顯示的影像品質。The electronic display device used in the digital signage is now constantly developing and progressing. Consumers started to demand for displaying on large screen increasingly, and the required size of signage is usually much larger than the size used in the market recently. Therefore, the need of tiled screen emerges. In this study, we adopt the design of using software and hardware together to produce a system of tiled digital signage. We make a connection to client Android media player on embedded platform, and cut broadcast video to transmit it to fast interpolator on FPGA platform through media content management of cloud-computing digital signage. Each interpolator enlarges the image of the cut video and shows it on independent LCD to complete LCD tiled display. Finally, we accomplished the integration of software and hardware of digital signage. We also found that the display of VGA can reach to 16.2 Frames/sec. In this study, the method and system structure we proposed can decrease the costs of LCD tiled system and enhance the quality of displaying tiled image.
