  • Patent number: 8259089
    Abstract: An electronic device includes a light-emitting board, a touch sensor film and a signal connection part. The light-emitting board includes a driving substrate, and a semiconductor device disposed on a surface of the driving substrate. The touch sensor film includes a film disposed over the light-emitting board, and a touch conductor pattern formed on the film to sense an external touch event for generating a touch signal to drive the semiconductor device. The signal connection part electrically connects the touch sensor film and the light-emitting board to each other to transmit the touch signal from the touch sensor film to the light-emitting board.
