Problems solved by technology

[0007] It should be understood that the apparatus used in the above-mentioned US patents is used to communicate character information, however, if the number of actuators has to be increased, the apparatus will quickly become inefficient
For devices capable of reaching hundreds of actuators, the method described in this patent is no longer usable due to the complex assembly and wiring, especially when the system is to be miniaturized

Abstract

The invention relates to a touch display device (10) which is characterised in that it consists of stacked layers (1, 4). An insulating layer (2) is disposed between a touch plate (1) and a layer (3) comprising selectively-addressable flat coils (31), said insulating layer containing holes (21) for the movement of blades (12) which are connected to said touch plate (1). According to the invention, the tactile appearance of the touch plate (1) can be modified by altering the value of the currents addressed to the different coils (31).

Description

technical field [0001] The invention relates to a device for communicating touch information to a user. More specifically, the present invention relates to a display device comprising: [0002] a touchpad having a touch surface; [0003] a network of magnetic coils and a network of haptic-altering moving parts that are actuated in response to current flowing in the coils to produce a tactile sensation on the touch surface that is a function of the current flowing in each coil, [0004] addressing circuitry for selectively accessing the currents in the different coils of the microactuator, [0005] The magnetic coil moves the moving part, which deforms or vibrates a portion of the touch surface. The concave-convex deformation of the touch surface or its vibration produces a tactile sensation that can be detected by the user. This addressing circuit allows selection of the appropriate microactuator to actuate at a given instant for producing the desired haptic sensation with...
