Light Emitter Diode (LED) character and graphic display are currently the better products for LED application, which include LED lighting, LED display board, traffic sign indication and so on. Those products can involve the full-color display system so that their outdoor applications are better than that of LCD display. However, the designs and applications of LED display board belong to the customized products such that the application field will be limited by its flexibility. Therefore, in order to provide a free assembly LED display module for increasing the extendable capability, this paper proposes an embedded LED display module and application architecture using real-time controller area network. The customized LED character and graphic display board system can be easily achieved by the firmware design of the main control board and slave display module, based on timer-trigged controller area network (TTCAN). Eventually, the proposed embedded display modules is verified by the practical testing of 109 x 36.5 cm (144 x 48 LED points) display board system with encouraged performance.
