Tactile Touch Display Using Segmented-Electrode Array with Tactile Strength Stabilization

We developed an 8.4-inch electrostatic-tactile touch display using a segmented-electrode array (30×20) as both tactile pixels and sensors. Each pixel can be excited independently so that the allows presenting real localized textures in any shape. A driving scheme which strength is independent of grounding state human body by employing two-phased actuation was also proposed demonstrated. Furthermore, crosstalk investigated to find it due voltage fluctuation diminished applying aforementioned scheme.
