Embodiment Construction

[0032] Figure 5 It is a schematic diagram of the connection between the LCD backlight module and the liquid crystal panel of the present invention. Such as Figure 5 As shown, the main structure of the LCD backlight module includes: a plastic frame 1, a liquid crystal panel (not shown in the figure), a metal backplane 6 and a metal frame 10, and the plastic frame 1 and the metal backplane 6 pass through the first fastener 11 are buckled together, the metal frame 10 and the metal back plate 6 are buckled together by the second buckle 12 to fix the liquid crystal panel, and the liquid crystal panel is connected with a flexible connecting line (not shown in the figure). Wherein the plastic frame 1 is provided with several pairs of barrier strips 13, and the barrier strips 13 are located below the flexible connection line and play a role in supporting the flexible connection line. The barrier bar 13 and the plastic frame 1 are integrally structured, and can be molded at one tim...

Abstract

The invention relates to a liquid crystal display backlight module comprising a plastic frame, a metal backboard, a metal outer frame, a liquid crystal panel, a flexible connecting wire, and a plurality of pairs of baffle strips, wherein the plastic frame is buckled with the metal backboard by a first buckling piece, the metal backboard is buckled with the metal outer frame by a second buckling piece and fixes the liquid crystal panel, the liquid crystal panel is connected with the flexible connecting wire, and the baffle strips for supporting the flexible connecting wire are arranged on the plastic frame. The baffle strips are arranged on the plastic frame and below the clear areas of the flexible connecting wire and only contact the clear areas on two sides of the flexible connecting wire, thereby preventing metal foreign bodies from entering a flexible connecting wire region and supporting the flexible connecting wire simultaneously and decreasing the friction probability between the flexible connecting wire and the plastic frame, thereby decreasing the probabilities that the flexible connecting wire protection layer is melted and the lead wire area of the flexible connecting wire is short. The production quality of the liquid crystal display backlight module is improved, and the defective rate caused in the transportation process is reduced.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module applied to a liquid crystal display. Background technique [0002] Liquid Crystal Display (hereinafter referred to as LCD) is a passive light-emitting device, mainly composed of a liquid crystal panel and a backlight module. Since the liquid crystal layer in the liquid crystal panel itself has no function of emitting light, it is necessary to set a backlight module to provide a light source for the LCD to realize image display. In a transmissive LCD, a backlight module is used to provide a light source with high brightness and uniform brightness distribution for the liquid crystal layer, and the display of the liquid crystal display is controlled by controlling the transmittance of the liquid crystal. [0003] figure 1 It is a structural schematic diagram of an LCD backlight module in the prior art, figure 2 It is a structural schematic diagram of an LCD liquid crystal...
