Abstract
A method and apparatus of actuator mechanisms for a multi-touch tactile touch panel are disclosed. The tactile touch panel includes an electrical insulated layer and a tactile layer. The top surface of the electrical insulated layer is capable of receiving an input from a user. The tactile layer includes a grid or an array of haptic cells. The top surface of the haptic layer is situated adjacent to the bottom surface of the electrical insulated layer, while the bottom surface of the haptic layer is situated adjacent to a display. Each haptic cell further includes at least one piezoelectric material, Micro-Electro-Mechanical Systems (“MEMS”) element, thermal fluid pocket, MEMS pump, resonant device, variable porosity membrane, laminar flow modulation, or the like. Each haptic cell is configured to provide a haptic effect independent of other haptic cells in the tactile layer.

35. A tactile touch panel comprising:
-
a piezoelectric layer having a first surface and a second surface, wherein the first surface of the piezoelectric layer is configured to receive inputs, and the second surface of the piezoelectric layer is opposite to the first surface; and a control circuit, wherein the piezoelectric layer comprises an array of cells that are individually addressable via electrical wires that directly address every cell of the array of cells, and wherein each cell of the array of cells is able to be activated independent of other cells of the array of cells, and wherein the control circuit is configured to individually activate one or more cells of the array of cells. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A tactile touch panel comprising:
-
a display; a substantially transparent haptic layer having a first surface and a second surface, wherein the first surface of the haptic layer is configured to receive inputs, and the second surface of the haptic layer is disposed adjacent to the display, the haptic layer being formed of a shape memory alloy or a micro electro mechanical system (MEMS) element; and a control circuit, wherein the haptic layer comprises an array of cells that are individually addressable via electrical wires that directly address every cell of the array of cells, and wherein each cell of the array of cells is able to be activated independent of other cells of the array of cells, and wherein the control circuit is configured to create multiple asynchronous haptic effects across a surface of the display by individually activating multiple cells of the array of cells. - View Dependent Claims (51, 52, 53)
