Abstract: A light-emitting diode (LED) display panel and a display device are provided. The LED display panel includes a substrate, an array layer at a side of the substrate, and a light-emitting device at a side of the array layer away from the substrate. The array layer includes an insulating layer and a driving device; the insulating layer includes a groove; the groove is between an edge of the display panel and the driving device; and/or the groove is between the light-emitting device and the driving device.

Abstract: A display panel includes a pixel circuit that includes a light emitting module, a driving module, a first dual control module, and a second dual control module. A control end of the driving module is connected to a first node. The first dual control module has a control end connected to a first scanning line and has a first end connected to the first node. A first capacitor is formed between an intermediate node of the first dual control module and a first potential line. The second dual control module has a first end connected to the first node and has a second end connected to the driving module. A second capacitor is formed between an intermediate node of the second dual control module and a second potential line. Capacitance of one of the first capacitor and the second capacitor is greater than another.
