<p>The present invention relates to an actuator for tactile display device. According to the present invention, the actuator for tactile display device includes: a frame which is arranged on multiple grooves; a flexible substrate which is combined with the frame to cover the groove; an insulation member which is installed inside the groove between the lower side and the separation space of the flexible substrate; and an electrode pattern unit having a first and a second electrode pattern which are installed and insulated in a horizontal direction on the insulation member to be separated to switch according to an input signal. The present invention induces a charge having a polarity opposite to each electrode pattern on a surface of the flexible substrate in a location corresponding to each electrode pattern when a power is applied to each electrode pattern and generates attraction force. The flexible substrate pulls to the inside of the separation space by the attraction force and vibrates toward the inside and outside of the separation space by the switching of the power. Accordingly, the present invention reduces breakdown due to frequent use by exposing both sides of a vibration part of the actuator in the air and reduces malfunction without stacking a capacitance by frequent touch by separating a part where the power is applied from a part where is touched from the outside.</p> |
