The application relates to a drive substrate, light-emitting panel and display device. The drive substrate is configured to drive a light-emitting element. The drive substrate includes a light-emitting area and a frame area surrounding at least a part of the light-emitting area. The drive substrate includes a substrate; and a device layer disposed on the substrate, the device layer including a pixel drive circuit disposed in the light-emitting area, and an electrostatic discharge circuit, a first signal line and a second signal line disposed in the frame area, the first signal line being electrically connected to at least one of the pixel drive circuit and the light-emitting element, and the second signal line being electrically connected to the electrostatic discharge circuit; wherein the second signal line is disposed on a side of the first signal line away from the light-emitting area and is spaced from the first signal line.

Drive substrate, light-emitting panel and display device

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.
