A display panel (10) having a touch function and a fault detection method. The display panel (10) comprises a display component and a touch component. The display component and the touch component share common electrodes (11-54). The common electrodes (11-54) are divided into a plurality of areas that are arranged in an array, and a common electrode in each area is connected to a touch chip (102) through one detection line (101). The display panel further comprises at least two switch control lines (O-Vcom, E-Vcom) that control, by predetermined means, the detection lines (101) corresponding to the multiple areas so that the common electrode in each area and the common electrodes in adjacent areas are controlled by different switch control lines (O-Vcom, E-Vcom); the common voltages of the common electrodes (O-Vcom, E-Vcom) in the multiple areas are configured by means of the at least two switch control lines (O-Vcom, E-Vcom) when the display component conducts display, and the presence of detection line (101) faults is determined by detecting the display states of the display component in the multiple areas. By means of the method, detection of a TP line can be simply and effectively achieved. |
