  • Publication number: 20110291928
    Abstract: The present invention discloses a multifunctional flexible handwriting board and its manufacturing method. The multifunctional flexible handwriting board comprises a name plate, a linear plate, a shock absorbing layer and a circuit board. The name plate is made of a flexible material and has an upper surface uses as a mouse pad. The linear plate is made of a flexible material and has a sensing area at the middle. The shock absorbing layer is made of a soft material for protecting the linear plate. The circuit board is electrically coupled to the sensing area of the linear plate for transmitting information. The method of manufacturing the multifunctional flexible handwriting board is to couple the circuit board to an edge of the linear plate and sequentially couple the name plate, the linear plate and the shock absorbing layer.
