Data transmission and reception through optical in-LCD sensing panels is provided. The transmission/reception can be a communication in which data is transmitted by displaying, on display pixels of the panel, a communication image encoding the data, and data is received by capturing, with EM sensors embedded in the panel, a communication image encoding the data that is displayed in proximity to the panel. The transmission/reception can be a scan in which a motion of a handheld device is determined by scanning a surface with the EM sensors at different times and comparing the corresponding scan images to obtain the motion of the device. A control signal based on the motion of the handheld device can be transmitted to an external device, for example, to control a mouse cursor. In another example, scan images can be combined based on the motion to generate a combined scan image of a surface.
