Problems solved by technology

[0003] Since the LED single lamp is welded on the PCB board with solder paste, it is necessary to correctly correspond to the positive and negative poles of the LED single lamp and the PCB board. Due to the small difference between the positive and negative poles, it is easy to cause positive and negative poles caused by human misoperation or equipment missetting. The phenomenon of reverse connection, resulting in the situation that the LED lamp cannot be lit or even dead.

Abstract

The invention relates to the technical field of LED display, and discloses an LED light bar, a backlight module and a display device. The LED light bar includes an LED lamp and a PCB substrate, the LED lamp includes an LED bracket, and the LED bracket is provided with a positive protrusion and a negative protrusion, and the shape and / or size of the positive protrusion and the negative protrusion are different; the PCB A positive electrode pad and a negative electrode pad are arranged on the substrate, and the positive electrode protrusion and the negative electrode protrusion are respectively fixed on the positive electrode pad and the negative electrode pad. The backlight module includes the above-mentioned LED light bar, and the display device includes the above-mentioned backlight module. The shape and / or size of the positive and negative protrusions of the LED light are different, which is easy to distinguish, effectively realizes the fool-proof function, ensures that the positive and negative poles correspond correctly, avoids the phenomenon of reversed positive and negative poles, and improves the LED light bar. pass rate.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED light bar, a backlight module and a display device. Background technique [0002] At present, the light bar used in the traditional direct-lit backlight is composed of a lens, an LED light and a PCB board. Among them, the LED lamp is to weld the positive LED chip on the LED bracket through silver glue, and then connect the positive and negative poles of the chip and the positive and negative poles of the LED bracket through gold wire welding, and then add the optical glue containing phosphor to heat and cure to form an LED. single light, and then use solder paste to solder the LED single light on the PCB light bar, and use epoxy resin to fix the lens on the top of the LED single light to form a direct-type LED light bar. [0003] Since the LED single lamp is welded on the PCB board with solder paste, it is necessary to correctly correspond to the positive and negative...
