We developed an FPGA-based tiled display system as a wearable display. Four 15.6-inch displays are arranged in a grid and formed a single display which has an input of HDMI signal. FPGAs are used to divide and scale the image into four LCD panels. This system can be used as a wearable display, such as a digital sandwich man. A smartphone which supports MHL output can be connected to the system, and users can modify the contents of the display on the fly. The merit of using hardware is that displays can be synchronized enough to play movies on them; No screen tearing occurs. The system consumes lower power than a single display with equivalent size.
