Abstract
Provided are a LED display unit group and a display panel. The LED display unit group includes a circuit board and pixel units arranged in an array of m rows and n columns on the circuit board. The circuit board includes N metal line layers stacked in sequence and an insulating plate located between adjacent metal line layers. The N metal line layers are electrically connected through a conductive via on the insulating plate, where N≥2. Each pixel unit includes at least two LED light-emitting chips with different light-emitting colors, where m≥2, n≥2. The first metal line layer includes m common A-electrode pads, multiple A-electrode pads and multiple B-electrode pads.
