Definitions

  • the drive control circuit 41 applies the driving signal Tx selectively to the driving electrode 21 .
  • the detection data Vdet is generated in all the sensing electrodes 22 in synchronization with the application of the driving signal Tx. The above-described procedure is performed on all the driving electrodes 21 to generate the detection data Vdet of all the facing portions formed in the touch panel 20 .
  • Step S 08 When the signal component Vs is larger than the threshold, the TPIC 40 collates the obtained detection data Vdet with a pre-registered noise pattern to determine whether or not noise is included in the detection data Vdet. When the TPIC 40 determines that there is noise, the procedure proceeds to step S 12 . When the TPIC 40 determines that there is no noise, the procedure proceeds to step S 09 .
  • processing functions may be implemented on a computer.
  • a program describing the processing content of a function which each display apparatus needs to have is provided.
  • a computer system executes those programs, thereby providing the above-described processing functions.
  • the programs may be stored in computer-readable media.
  • Such computer-readable storage media include magnetic storage apparatuses, optical discs, magneto-optical storage media, semiconductor memory devices, and other non-transitory storage media.
  • the examples of the magnetic storage apparatuses include a hard disk drive (HDD; Hard disk Drive), a flexible disc (FD), and a magnetic tape.
