DEVICE, MODULE AND METHOD FOR TACTILE DISPLAY

摘要

PURPOSE: A haptic display device, a module thereof, and a method thereof are provided to simplify a manufacturing process through a solid couple ring and to miniaturize the size of an integrated module. CONSTITUTION: An actuator(10) includes an electrode unit(12) expanded and contracted by receiving an external voltage. A frame unit(14) includes openings having different sizes, is connected to the actuator, and includes the electrode unit in the end of the openings. A deforming unit(18) is coupled with the frame unit through the openings, contacted to a side of the electrode unit, and is deformed by expanding and contracting power of the electrode unit. A touch spot(20) is formed on a surface of the deforming unit in the openings to move up and down by the deformation of the deforming unit with the expanding and contracting power.
