Backlight module group and fixing cap for fixing cable

Abstract

The invention relates to a backlight module, which comprises a first substrate, a second substrate, a light source, a cable and a fixing cover, wherein the first substrate includes a groove; the second substrate includes a plate body and a hook protruding out of the plate body and is arranged above the first substrate to form a first containing space with the first substrate; the light source is disposed in the first containing space; the cable is positioned above the second substrate and is coupled with the light source; the fixing cover is arranged on the second substrate and includes a holding portion, a rotation shaft and a pin; the rotation shaft extends to the first side of the holding portion for driving the holding portion during rotation; and the pin extends to the second side of the holding portion and is inserted into the groove of the first substrate. Accordingly, the holding portion can form a second containing space together with the second substrate for containing the cable.

Description

technical field [0001] The invention relates to a backlight module and its fixing cover, especially to a backlight module capable of fixing cables and its fixing cover. Background technique [0002] The LCD panel (Liquid crystal display panel, LCDpanel) in the LCD is one of the key components. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and uniformly distributed light source, through simple and effective light The structure is transformed into a surface light source product with high brightness and uniform luminance, and the light emitted by the backlight module is converted by the liquid crystal so that the liquid crystal display panel can display images normally. Liquid crystal display panels are now widely used in monitors, notebook computers, digital cameras, projectors and other electronic products with growth potential, especially large-sized panels such as notebook computers and LCD monit...

AI Technical Summary

Problems solved by technology

It can be seen from FIG. 4 that the fixed cover 41 in the backlight module 40 is only connected to the base plate 42 in a snap-fit ​​manner, that is to say, the fixed cover 41 and the base plate 42 are detachable components. Therefore, during maintenance, the fixed cover 41 It is often disassembled from the base plate 42 to facilitate subsequent maintenance. After the maintenance is completed, the fixed cover 41 is put back on the base plate 42. In this way, it will not only cause inconvenience in maintenance, but also be more likely to be damaged due to temporary negligence. Cause the loss of the fixed cover 41

In addition, the fixed cover 41 and the substrate 42 are only connected in a snap-fit ​​manner, so it is easy to form a gap space, and then light leakage occurs at the opening 32 as shown in FIG. 4 , thereby reducing the brightness of the liquid crystal panel.
