Abstract

The invention relates to a backlight module and an anti-disengagement pre-assembly assembly thereof, the anti-disengagement pre-assembly component is formed by assembling a light guide plate and an LED lamp panel in advance, the light guide plate is provided with an inlaying and buckling groove, and the periphery of the inlaying and buckling groove forms a protective edge. In an example, the protective edge is integrally formed by the light guide plate. The LED lamp panel is embedded in the embedding and buckling groove of the light guide plate, the protective edge wraps the side edge of the LED lamp panel and protrudes out of the back face of the LED lamp panel, the back face of the LED lamp panel is exposed out of the embedding and buckling groove, and the light-emitting face of the LEDlamp panel faces the light-facing face of the embedding and buckling groove to form a fixed gap or is tightly attached to the light-facing face. The basic technical scheme of the invention has the effect of preventing the LED lamp panel from being vibrated and rubbed to influence the light emitting effect of the light guide plate, and the specific application occasion of one example is the vehicle-mounted display device.

Description

Technical field [0001] Technical Field The present invention relates to a backlight module, particularly applicable to vehicle-mounted display, vibration or harsh environment military grade products such as a display, particularly to a backlight module and retaining the pre-assembly group. Background technique [0002] The backlight module as a light source display screen, a light guide plate and the LED light board assembly is fixed in the individual backlight module. Side light guide plate is emitted from the LED chip through reflection surface of the light guide is generally employed in the edge-lit backlight module, but also some direct type backlight module using the light guide plate, a backlight module that either, traditionally the light guide plate and the LED lamp board are individually mounted to the back plate or the backlight module housing base, the light guide plate and stopper pad of silica gel using backsheet, an elastic pad of silica gel. When using a display ca...
