Display and method for driving the display

A display comprising:

• an electro-optical material;
• a conductor that affords an electrical signal to said electro-optical material;
• a first electrically conductive film that affords an electrical signal to said electro-optical material;
• a second electrically conductive film provided on a viewing area of said display;
• a current detection circuit that detects a current on said second electrically conductive film;
• a control circuit that, during a time period the current is detected by said current detection circuit, affords substantially the same voltage as that applied to said second electrically conductive film to one of said conductor and said first electrically conductive film, and sets the other in a floating state;
• and
• a detecting unit that detects, based on the current detected by said current detection circuit, whether or not touch has been made by a finger or a pointer and where the touch has been made.

A driving method for a display comprising:

• providing a display including:
• an electro-optical material arranged between first and second planes facing each other;
• a first substrate arranged on said first plane and including a thin film transistor and a conductor that affords an electrical signal to said electro-optical material;
• a first electrically conductive film arranged on said second plane to afford an electrical signal to said electro-optical material;
• and
• a second electrically conductive film arranged outside an area sandwiched between said first and second planes;
• detecting the current on said second electrically conductive film by a current detection circuit;
• applying, during a time period the current is detected by said current detection circuit, substantially the same voltage as that applied to said second electrically conductive film to one of said conductor and said first electrically conductive film which is arranged more proximate to said second electrically conductive film, and setting the other in a floating state, or applying substantially the same voltage as that applied to said second electrically conductive film to both said conductor and said first electrically conductive film;
• and
• detecting, based on the current detected by said current detection circuit, whether or not a touch has been made by a finger or a pointer and where the touch has been made.

• a control circuit that, during a time period the current is detected by said current detection circuit, applies a voltage which is substantially the same in amplitude and phase as that applied to said second electrically conductive film, to one of said conductor and said first electrically conductive film while setting the other in a floating state, or that applies said voltage to said conductor and to said first electrically conductive film;
• and
• a detecting unit that detects, based on the current detected by said current detection circuit, whether of not touch has been made by a finger or a pointer and where the touch has been made.
