Embodiment Construction

[0035] The invention provides a backlight module. The top of the plastic frame of the backlight module has a covering integrally formed with the plastic frame and extending toward the middle of the backlight module. When assembling the liquid crystal display module, the cover is used to fix the display panel. Since the cover is integrally formed with the plastic frame, it has high rigidity and improves the firmness of fixing the liquid crystal panel. When the liquid crystal display device includes an external functional panel, the higher rigidity of the cover greatly improves the bonding effect between the functional panel and the backlight module, and under the action of pressure, whitening and light leakage will not occur around the product The problem.

[0036] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present inventi...

Abstract

The invention relates to the technical field of display, and discloses a backlight module and a liquid crystal display device. The top of a plastic frame of the backlight module is provided with a cover integrally molded with the plastic frame and extending to the middle of the backlight module. When a liquid crystal display module is assembled, the cover is used for fixing a display panel. The cover and the plastic frame are integrally molded, so the structure of the backlight module is simplified; the cover has higher rigidity, so the firmness of the liquid crystal panel is improved. When the liquid crystal display device comprises an external hanging type function panel, the bonding effect of a touch panel and the backlight module is greatly improved by the higher rigidity of the cover, and the periphery of a product cannot generate whitening and light leakage problems under the action of pressure.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] Since the liquid crystal itself does not emit light, in various liquid crystal display devices (Liquid Crystal Display, hereinafter referred to as "LCD") such as liquid crystal displays and liquid crystal TVs, it is necessary to rely on an external backlight module to realize display. combine figure 1 As shown, the backlight module includes a backplane 1, a reflector 10 arranged on the backplane 1, a light guide plate 9 and an optical film 8 from bottom to top, and also includes a backlight (not shown in the figure) and a The plastic frame 4' of the reflective plate 10, the light guide plate 9 and the optical film material 8, and the liquid crystal panel 7 are placed on the boss inside the plastic frame 4'. For small and medium-sized liquid crystal display modules, the adhesive tape 3 is bond...
