Abstract
In a method of driving touch sensing display panel and a display apparatus for performing the method, image data are outputted to the touch sensing display panel during an active period of a frame, the touch sensing display panel comprising a display substrate including a switching element connected to a data line extending in a column direction and a gate line extending in a row direction, and a touch sensing substrate including a light sensing part connected to a read-out line substantially parallel to the data line and a scan line substantially parallel to the gate line. A sensing signal is read out through the read-out line during a blanking period of the frame.
