Display device and coordinate notification method

Abstract

When an application displays image straddling display units (110-1 and 110-2), a coordinate conversion unit (120) uses a predetermined operation to transform the physical coordinates indicating the position at which a display unit (110-1 or 110-2) senses contact to virtual coordinates and supplies the virtual coordinates. A coordinate notification unit (130) notifies an application (140) of the physical coordinates at which contact was sensed when the application is displaying the image on one of the display units (110-1 or 110-2) and notifies the application (140) of the virtual coordinates supplied by the coordinate conversion unit (120) when the one application is displaying the image straddling the display units (110-1 and 110-2).

1 .- 2 . (canceled) 
     
     
         3 . A display device comprising:
 a plurality of display units with a touch panel function and that display an image comprising information;   a coordinate conversion unit that, when an application is displaying said image straddling said plurality of display units, uses a predetermined operation to convert physical coordinates that indicate a position at which one display unit of said plurality of display units senses contact to virtual coordinates; and   a coordinate notification unit that, when the application is displaying said image straddling said plurality of display units and the display device is rotated, the coordinate notification unit uses the predetermined operation in accordance with a degree of the rotation.   
     
     
         4 . The display device as set forth in  claim 3 , wherein said coordinate conversion unit converts the physical coordinates on, from among said plurality of display units, a display unit other than a primary display unit that includes the coordinates of an origin that said application recognizes, to said virtual coordinates. 
     
     
         5 . The display device as set forth in  claim 4 , wherein said coordinate conversion unit converts, from among said physical coordinates, a coordinate of a direction along which said primary display unit and the display unit other than the primary display unit are aligned. 
     
     
         6 . The display device as set forth in  claim 5 , wherein said coordinate conversion unit carries out conversion to said virtual coordinates by adding a coordinate portion that accords with a size of said primary display unit to physical coordinates on display units other than said primary display unit. 
     
     
         7 . The display device as set forth in  claim 3 , wherein said coordinate conversion unit carries out conversion of said physical coordinates to said virtual coordinates according to movement of physical coordinates with respect to an origin that said application recognizes that is caused by rotation of the length and width of the display device. 
     
     
         8 . The display device as set forth in  claim 3 , wherein the coordinate notification unit reports said virtual coordinates to the application.
