Embodiment Construction
[0030] As mentioned in the above-mentioned background technology, the traditional LED display unit group structure is limited by the size of the pads and metal traces, and it is difficult to further reduce the size of the display unit group. It is impossible to increase the integration of small-pitch LEDs and improve its circuit stability.
[0031] In view of the above technical problems, the embodiments of the present invention propose the following technical solutions:.
[0032] The LED display unit group includes: a circuit board, wherein the circuit board includes N layers of metal circuit layers stacked in sequence, and an insulating plate located between adjacent metal circuit layers, and the N layers of metal circuit layers pass through the conductive vias on the insulating plate Electrically connected, where N≥2; pixel units arranged in an array of m rows and n columns are located on the circuit board, each pixel unit includes at least two LED light-emitting chips with...

The invention discloses an LED display unit group and a display panel. The LED display unit group comprises a circuit board, wherein the circuit board comprises N layers of metal circuit layers stacked in sequence and an insulating plate located between adjacent metal circuit layers, the N layers of metal circuit layers are electrically connected through conductive via holes in the insulating plate, and N is greater than or equal to 2; and pixel units which are arranged on the circuit board in an m-row n-column array mode, wherein each pixel unit comprises at least two LED light-emitting chipswith different light-emitting colors, the LED light-emitting chips are fixed on the first metal circuit layer, m is larger than or equal to 2, and n is larger than or equal to 2; the first metal circuit layer comprises m common A-pole bonding pads, a plurality of A-pole bonding pads and a plurality of B-pole bonding pads, the common A-pole bonding pads and the A-pole bonding pads are integrally formed, and all the A-pole bonding pads in each row of pixel units are electrically connected with the corresponding common A-pole bonding pads. According to the technical scheme, the integration levelof the LED light-emitting chip is improved while the circuit stability of the LED light-emitting chip is ensured.
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...
