Embodiments of the disclosure generally provide an integrated control system having an integrated controller that is configured to provide both display updating signals to a display device and a capacitive sensing signal to a sensor electrode that is disposed within the integrated input device. The internal and/or external signal routing configurations described herein can be adapted to reduce signal routing complexity typically found in conventional devices and reduce the effect of electrical interference created by the capacitive coupling formed between the display routing, capacitive sensing routing and/or other components within the integrated control system. Embodiments can also be used to reduce electromagnetic interference (EMI) on the display and touch sensing signals received, transmitted and processed within the integrated control system.

A method implemented by a transmission device to communicate with multiple reception devices that respectively share a drawing area with the transmission device is provided.

Electromechanical actuators may be constructed as cylindrical elements with electrodes position around the cylindrical element. The electrodes may receive an electrical signal that causes a core material in the electromechanical actuator to change shape, thus providing haptic feedback to a user, such as when the actuators are integrated with a display screen of a smart phone. A position of the electrodes around the core material may affect a mode of operation of the electromechanical actuators. In one configuration, two electrodes may be located at opposite ends of the cylindrical element along a long axis of the cylinder. In another configuration, two electrodes may be located opposite each other along a circumference of the cylinder. Signals may be applied to the electrodes to generate vibrational feedback or textures on the display screen.
