A kind of led, backlight module and display device

Abstract

The invention provides an LED, a backlight module and a display device, relating to the technical field of LEDs. The luminous failure rate of the LED can be reduced. The LED comprises a first electrode, a second electrode, a main luminous unit and an auxiliary luminous unit, wherein the main luminous unit comprises a first luminous chip; the first luminous chip comprises a first pole and a second pole; the first pole of the first luminous chip is connected with the first electrode; the second pole of the first luminous chip is connected with the second electrode; the auxiliary luminous unit comprises a first end and a second end; the first end of the auxiliary luminous unit is connected with the first electrode; the second end of the auxiliary luminous unit is connected with the second electrode; and the auxiliary luminous unit is used for not giving out light under the condition that the first luminous chip gives out light and used for giving out light under the condition that the first luminous chip does not give out light. The LED is applied to the display device.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED, a backlight module and a display device. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) generally includes a liquid crystal display panel and a backlight module, and the backlight module uses an LED (Light Emitting Diode, light emitting diode) to provide backlight. The partition dynamic backlight liquid crystal display device divides the backlight into multiple independent control units, and accurately adjusts the brightness of the corresponding backlight area according to the light and dark distribution of each frame of image. Therefore, in terms of screen contrast, screen layering, dark field details, Compared with traditional liquid crystal display devices, the precise color reproduction and picture fluency have been greatly improved. [0003] The number of LED lights used in the backlight module of the partitioned dynamic backlight ...

AI Technical Summary

Problems solved by technology

[0003] The number of LED lights used in the backlight module of the partitioned dynamic backlight liquid crystal display device is relatively large, and the dismantling analysis of display faults such as black screens and dark areas of the existing display device further shows that the liquid crystal display panel is generally in normal state, and the display fault Mainly due to the failure of the LED single lamp in the backlight module, the backlight system cannot work normally.
