Claim Text:
1. A visual interface system, comprising: an operation apparatus; and a passive matrix display apparatus, comprising: a first substrate; a display surface located at a first side of the first substrate; and a second substrate disposed opposite to the first substrate and located at a second side of the first substrate relatively opposite to the first side; wherein, when the operation apparatus is operated on the display surface of the passive matrix display apparatus, an encoded signal is coupled to the operation apparatus from the passive matrix display apparatus, and the operation apparatus receives the encoded signal to obtain a transmission signal; wherein the passive matrix display apparatus has a plurality of electrodes disposed on the first substrate or the second substrate, and the encoded signal is applied to the electrode and is then capacitively or inductively coupled to the operation apparatus from the electrode, the encoded signal includes a reference time to identify the electrode that transmits the encoded signal.
