This paper demonstrates a novel high-definition (HD) display system using the optical interconnection technique. This system features a 20-million-pixel 40-in thin film transistor (TFT) liquid crystal display (LCD) comprising four 20-in LCDs each with five million pixels. A four-channel optical interconnection module, called an active interposer, was employed to transmit graphical data consisting of red, green, blue, and clock signals. For efficient coupling with multimode fibers and to effect a compact coupling structure, three-dimensional (3-D) waveguide arrays with two-dimensionally (2-D) integrated optical input/output and optical path redirection to the pigtail connectors of the active interposer were applied. This paper also employed eight transmitter (Tx) and receiver (Rx) active interposers and 50-m multimode fibers in the system, and with 32-channel parallel optical data transmission successfully displayed HD pictures on the LCD. The results indicate that active interposers are suitable for graphical data transmission and show promise for future applications that use the optical interconnection technique.
