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&#x2265;2. Each pixel unit includes at least two LED light-emitting chips with different light-emitting colors, where m&#x2265;2, n&#x2265;2. The first metal line layer includes m common A-electrode pads, multiple A-electrode pads and multiple B-electrode pads.

Provided are an LED holder, an LED device and an LED display screen. The LED holder includes a metal frame and a cup cover wrapping the metal frame. The cup cover includes a reflective cup. The cup cover has a first lateral surface and a second lateral surface disposed opposite to each other. A height of the first lateral surface is greater than a height of the second lateral surface. The metal frame includes metal pins exposed outside the cup cover and disposed on the first lateral surface and/or the second lateral surface. The bottom of the cup cover is of a sloping structure, so that the light emitted by an LED chip in the reflective cup propagates along a specified direction.
