A New LCD with an Input Function Using Conventional Electrodes for Both Display and Input

The research and development of the information terminals and systems which enable an operator to input data viewing characters and graphs-shown on the display have been increasing. Moreover, as the necessity of inputting graphic or hand written data increases, several types of data tablets become used in these systems widely.[l][2] It is an important problem how easily an operator can have an interactive conversation with these systems. However, conventional data tablets are inconvenient for the operator because they are set apart from a display monitor.
