摘要： Disclosed are an array substrate, a display panel and a driving method thereof. As the control unit is provided between the first electrode and the test circuit, when the panel is subsequently tested, the control unit may provide the circuit control signal received by the first electrode to the test circuit under the control of the third electrode, so as to detect whether the panel is qualified by using the test circuit. During subsequent display, the control unit may be used to cut off the first electrode from the test circuit, and fundamentally cut off the connection between the first electrode, and the test circuit and a flexible printed circuit, so that a display abnormality does not occur even if the first electrode is short-circuited.
