Abstract: A circuit board and a method for electrical performance detection thereof, a display panel, a method for fabricating a display panel, and a method for driving the display panel are provided. In the electrical performance detection, the signal output terminal is electrically connected to the detection terminal, and detection is performed on the drive signal by the electrical performance detection circuit to determine whether the circuit board is abnormal, achieving the electrical performance detection of the circuit board. In addition, in a process other than the electrical performance detection, the signal output terminal is disconnected from the detection terminal to avoid affecting a normal operation of the circuit board. The electrical performance detection of the circuit board is realized, a defective circuit board is prevented from flowing into a subsequent fabricating procedure, and waste of assembling resources is avoided.
