Visual interface system

摘要

A visual interface system includes an operation apparatus and a passive matrix display apparatus. The passive matrix display apparatus includes a first substrate, a display surface and a second substrate. The display surface is located at a first side of the first substrate, and the second substrate is disposed opposite to the first substrate and located at a second side of the first substrate relatively opposite to the first side. 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 substrate. The operation apparatus receives the encoded signal to obtain a transmission signal. The visual interface system can achieve the touch input function without configuring an additional touch panel, and is equipped with the near field communication (NFC) function.
