A kind of LED display unit group and display panel

Abstract

The present invention discloses an LED display unit group and a display panel. The LED display unit group includes: a circuit board, wherein the circuit board includes N layers of metal circuit layers stacked in sequence, and insulation between adjacent metal circuit layers. board, N layers of metal circuit layers are electrically connected through conductive vias on the insulating board, where N≥2; pixel units arranged in an array of m rows and n columns are located on the circuit board, and each pixel unit includes at least two different light emitting LED light-emitting chips of different colors, m≥2, n≥2; the first layer of metal circuit layer includes m common A-pole pads, and multiple A-pole pads and B-pole pads, A-pole pads and B-pole pads The pads are arranged in one-to-one correspondence with the A pole and the B pole of the LED light-emitting chip, and all the A pole pads in each row of pixel units are electrically connected to the corresponding common A pole pads. The technical solution provided by the embodiment of the present invention improves the integration degree of the LED light-emitting chip while ensuring the stability of the circuit.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of LED display, and in particular to an LED display unit group and a display panel. Background technique [0002] With the continuous development of display technology, indoor small-pitch LED displays will become the main technology development space in the future. The pixel unit density requirements of indoor small-pitch LED displays are getting higher and higher, that is, the pixel unit spacing is required to be smaller and smaller. [0003] As the number of light-emitting units integrated in the small-pitch LED display increases, the more metal pads, conductive leads and pins need to be set, resulting in difficulties in subsequent soldering, and the wiring of the PCB board will become more complicated. [0004] The traditional LED display unit group structure cannot achieve both increasing the integration of small-pitch LEDs and improving their circuit stability. Contents of th...
