  • Publication number: 20130187900
    Abstract: A court border module using a display apparatus is disclosed, which uses piezoelectric elements to drive the display apparatus. When a ball hits a court border, which is defined by the display apparatus, a force is applied to the piezoelectric elements which then generate power to drive the corresponding part of the display apparatus. The color of the part of the display apparatus hit by the ball is switched. Therefore the change in the color of the court border can be observed by officials and others to instantly and objectively determine whether the ball has hit the court border.
