HAPTIC FEEDBACK DISPLAY, HAPTIC FEEDBACK SYSTEM HAPTIC DRIVER, AND HAPTIC DRIVING METHOD

摘要

Embodiments of the present invention relate to a haptic feedback display, a haptic feedback system, a haptic driver, and a haptic driving method, wherein a preliminary driving voltage boosted from a base voltage is supplied to a haptic actuator before a haptic object is touched by a touch pointer, When the haptic object is touched by the touch pointer, a target voltage higher than the preliminary driving voltage is supplied to the haptic actuator and a driving wave having a waveform based on the target voltage is supplied to the haptic actuator, thereby increasing the haptic feedback speed.
