Abstract

The invention relates to an LED lamp bead and an LED display structure. The LED lamp bead comprises a lamp body, a light-emitting chip set and pins, wherein the light-emitting chip set is arranged onthe first end face of the lamp body, the pins are arranged on the second end face of the lamp body, the light-emitting chip set comprises at least one light-emitting chip, the pins comprise color signal pins and row signal pins, the number of the row signal pins is at least two, every two row signal pins of the same LED lamp bead are paired, one pair of row signal pins is electrically connected with each other through a circuit in the lamp body, one of the pair of row signal pins which are electrically connected with each other is directly connected with the electrode of the light-emitting chip, the other row signal pin is a redundant row signal pin, and the LED lamp beads are attached to PCB to form an LED display structure. By providing the redundant row signal pins, the color signal circuit and the row signal circuit can be arranged on the same layer of the PCB, so that the wiring difficulty and the manufacturing cost of the PCB are reduced.

Description

technical field [0001] The present application relates to the field of LED display, in particular to an LED lamp bead and an LED display structure. Background technique [0002] LED displays are widely used in more and more scenes such as outdoor display, monitoring center, advertising / media display, stage, etc. To realize a large-area LED display, it is necessary to connect the LED lamp beads into a matrix through a circuit, and then control the light emission of the lamp bead matrix through a control chip to achieve a variety of displays. At present, the LED lamp beads are usually mounted on the PCB board, and the LED lamp beads are arranged in an array on the PCB board and connected through the lines on the PCB board. [0003] Traditional LED lamp beads are generally equipped with 4 pins, which are R, G, B, and C pins, among which the R, G, and B pins correspond to the R chip, G chip, and B chip respectively, and the C pin is the row signal pin. foot. In the connection...
