Abstract
A pixel unit, method for sensing touch of an object, and a display apparatus incorporating the same are provided. The display apparatus includes a data line. The pixel unit includes a first switch circuit electrically connected to the data line and a sensing circuit electrically connected to the first switch circuit. The sensing circuit generates a signal in response to the touch of the object, while the signal is transmitted through the data line with the first switch circuit turned on. In addition, the display apparatus further includes a readout line. The pixel unit further includes a second switch circuit electrically connected to the readout line. The sensing circuit is electrically connected to the second switch circuit. In a first time period, the sensing circuit receives a reference voltage via the first switch circuit. Then the signal generated by the touch of the object is transmitted through the readout line via the second switch circuit in a second time period.
