Backlight module and liquid crystal display

Abstract

The invention discloses a backlight module and a liquid crystal display. The backlight module includes: a fixing plate and a plurality of light emitting groups, each of the light emitting groups includes a plurality of back plates and a light emitting assembly mounted on each of the back plates, and the back plates are detachably installed on the fixed on the board. The invention discloses a backlight module and a liquid crystal display. By setting a plurality of light-emitting groups on the fixing plate, the back plate of the light-emitting group is detachably installed on the fixing plate. When the light-emitting components of the light-emitting group are damaged, the corresponding In order to replace the damaged light-emitting components, it is not necessary to replace all the light-emitting groups, which can improve the replacement efficiency, and can also continue to use the intact light-emitting groups, saving costs.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display. Background technique [0002] Backlight is an essential device in liquid crystal displays, and the common types of backlight include side-lit backlight and direct-lit backlight. Among them, since the light-emitting diodes (LEDs) in the direct-lit backlight are arranged two-dimensionally and there are a large number of LED light bars, the direct-lit backlight design is adopted when the brightness of the liquid crystal display (LCD) backlight is high. [0003] The LEDs in the direct-lit backlight are usually made in the form of light strips. After arranging a plurality of light strips in sequence, the plurality of light strips are fixed on a whole backplane to facilitate power supply to the LEDs. At present, the backplane is all integrated design, which leads to the need to dismantle and replace once a certain part of the LCD backl...

AI Technical Summary

Problems solved by technology

At present, the backplane is all integrated design, which leads to the need to dismantle and replace once a certain part of the LCD backlight module has a problem, especially when there is a problem with the LED light strip, for example, when a certain LED light strip does not light up, it needs to be dismantled and replaced. It is very time-consuming and labor-intensive to completely disassemble the backlight, and other undamaged light bars cannot be used anymore, resulting in waste of materials
