Abstract: Provided is a light-emitting diode (LED) display unit group and a display panel. The LED display unit group includes a circuit board, and a pixel unit array located on the circuit board. The pixel unit array includes a plurality of pixel units arranged in n rows and m columns, n and m are both positive integers and greater than or equal to 2. Each of the pixel units includes multiple LED light-emitting chips of at least two colors, each of the LED light-emitting chips includes an electrode A and an electrode B of opposite polarities. The LED light-emitting chip of each of the pixel units includes at least one dual-electrode chip, the dual-electrode chip has the electrode A and the electrode B located on a same side of the dual-electrode chip. All dual-electrode chips in the plurality of pixel units of a same color have connecting lines from the electrode A to the electrode B directed in a same direction.
