DEVICE OF TACTILE PATTERN DISPLAY AND METHOD OF REALIZATION OF TACTILE PATTERN ON DISPLAY |
摘要 |
<p>PURPOSE: A touch pattern display apparatus and touch pattern creation method on a display unit are provided to offer a vibration pattern by installing a piezoelectric actuator at four borders of the display unit. CONSTITUTION: A graphic display unit(110) is combined with the front side of a frame. A piezoelectric actuator(420) creates a vibration pattern by vibrating the graphic display unit at the rare side of the graphic display unit. A control unit creates an operating signal inputted to a piezoelectric actuator. The vibration pattern changes the size of vibration by modulating the amplitude of the operating signal. The vibration pattern changes a location where the maximum displacement of the vibration is generated by modulating the frequency of the operating signal.</p> |
