CAPACITIVE TOUCH DISPLAY APPARATUS

摘要

A capacitive touch display apparatus includes a liquid crystal (LC) display module, a touch panel and a judgment unit. The LC display module includes an active device array substrate, a color filter (CF) substrate, and an LC layer disposed between inner sides of the two substrates. The touch panel includes a single touch sensing layer fabricated on an outer side of the CF substrate and a cover lens disposed on the single touch sensing layer. The single touch sensing layer includes a transmitter patterned electrode and multiple receiver patterned electrodes. A same inductive capacitor is formed between each receiver patterned electrode and the transmitter patterned electrode. The judgment unit transmits a scan signal to the transmitter patterned electrode, and determines whether there is an occurrence of a single-touch event or a multi-touch event by analyzing inductive signals from the respective receiver patterned electrodes.
