Abstract: The disclosure provides an LED display unit group and display panel, including a pixel unit array of n rows and m columns of pixel units. n and m are positive integers not less than 2. Each pixel unit includes a first, a second and a third LED chip. In the i-th row, the A-electrodes of all the LED chips in m pixel units are connected together, and are electrically connected to the i-th common A-electrode pin. In the j-th column, the B-electrodes of n first LED chips are connected together and are electrically connected to the j-th first B-electrode pin, the B-electrodes of n second LED chips are connected together and electrically connected to the j-th second B-electrode pin, and the B-electrodes of n third LED chips are connected together and are electrically connected to j-th third B-electrode pin of the LED display unit group.

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.
