Title:
LED LAMP BEAD AND LED DISPLAY STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/184810
Kind Code:
A1
Abstract:
An LED lamp bead (10) and an LED display structure. An LED lamp bead (10), comprising a lamp body (110), a light-emitting chip set (120) and pins (130). The light-emitting chip set (120) is provided on a first end face (110a) of the lamp body (110), and the pins (130) are provided on a second end face (110b) of the lamp body (110); the light-emitting chip set (120) comprises at least one light-emitting chip; the pins (130) comprise color signal pins (131) and row signal pins (133), there are at least two row signal pins (133), and two row signal pins (133) of the same LED lamp bead (10) are paired; a pair of row signal pins (133) are electrically connected to each other by means of a circuit inside the lamp body (110); and among a pair of row signal pins (133) electrically connected to each other, one is directly connected to an electrode of a light-emitting chip, and the other is a redundant row signal pin (133). The LED lamp bead (10) is mounted on a PCB board to form an LED display structure. By providing a redundant row signal pin (133), a color signal circuit and a row signal circuit can be provided on the same layer of a PCB, thereby reducing wiring difficulty and manufacturing costs of the PCB.
