DISPLAY APPARATUS AND TOUCH SENSING METHOD THEREOF |
摘要 |
A touch sensing method of a display apparatus is disclosed. The display apparatus includes an active matrix substrate including a plurality of column electrodes and a plurality of row electrodes crossing the column electrodes. Each of the column electrodes is electrically connected to a driving module or a sensing module. The touch sensing method comprises steps of: transmitting a scan driving signal to at least a row electrode; transmitting a touch driving signal to the column electrode electrically connected to the driving module; capacitively coupling the touch driving signal through at least an external object, and receiving a coupling signal by the column electrode electrically connected to the sensing module; and detecting the position of the external object according to the coupling signal. Therefore, the invention can be directly applied to the active matrix substrate and enhance the accuracy of the touch sensing. |
