Abstract
A display panel with multi-touch function includes a display area and a non-display area. The display area includes a data line, a gate line, a first sensing line, a second sensing line, and a sensing unit. The sensing unit electrically connects the first and second sensing lines according to a touch signal or electrically isolates the first sensing line from the second sensing line. The non-display area includes a gate driver, a first switch and a second switch. The first switch provides a path for charging the second sensing line according to a scan signal, and the second switch provides a path for discharging the second sensing line according to a reset signal.
