ABSTRACT:
A display device has a touch pad and a display lamintated together to form a screen, That screen is connected to a controller which processes signals generated by physical contact with the touch pad and activates the display to display e.g. characters input by a stylus to the touch pad. The display device is connected to an external device (e.g. a computer) and video signals from the external device are received via a video input and may be displayed on the display. Also the controller can transmit to the external device via an output. Thus, the display can simultaneously display information from the external device and information input to the touch pad. If the controller is arranged to carry out character recognition, the display device may then act as a handwriting input device, with the handwritten information being incorporated with information in the external device and displayed.
