Problems solved by technology

[0002] At present, in order to prevent one LED lamp bead from being damaged when the LED lamp bead is cascaded, which will affect the normal use of all the lamp beads behind the lamp bead, most of them use six-wire drive, that is, when the LED lamp bead has a problem, use the spare input signal line The transmission of signals avoids affecting the global LED display. This way of wiring is more complicated

Abstract

The invention provides an LED lamp bead with four-wire internally-sealed IC with a bidirectional data transmission function. The LED lamp bead comprises an LED light-emitting unit, a bidirectional data transmission IC chip, a power conversion chip, a packaging carrier and packaging glue. The power conversion chip is connected with the bidirectional data transmission IC chip and the LED light-emitting unit through metal wires, and parallel output pins of the bidirectional data transmission IC chip are connected with the LED light-emitting unit through metal wires. The packaging carrier is further provided with four metal conductive bonding pads, the LED light-emitting unit, the bidirectional data transmission IC chip and the power conversion chip are fixedly arranged on the metal conductivebonding pads, and the LED light-emitting unit, the bidirectional data transmission IC chip and the power conversion chip are fixed to the packaging carrier through the packaging glue. According to the technical scheme, the problem that in the prior art, normal use of all lamp beads behind an LED lamp bead is affected due to the fact that the LED lamp bead is damaged is solved, global LED displayis effectively prevented from being affected, and meanwhile the beneficial effects of being simple in wiring and the like are achieved.

Description

technical field [0001] The present invention relates to the field of bidirectional data transmission LED display technology, in particular, to an LED lamp bead with bidirectional data transmission and four-wire internal IC sealing. Background technique [0002] At present, in order to prevent one LED lamp bead from being damaged when the LED lamp bead is cascaded, which will affect the normal use of all the lamp beads behind the lamp bead, most of them use six-wire drive, that is, when the LED lamp bead has a problem, use the spare input signal line The transmission of signals avoids affecting the global LED display. This way of wiring is more complicated. Contents of the invention [0003] According to the technical problem raised above, an LED lamp bead with two-way data transmission and four-wire inner IC is provided. The technical means adopted in the present invention are as follows: [0004] An LED lamp bead with two-way data transmission and four-wire internal sea...
