Embodiment Construction

[0012] The invention provides an improved backlight module structure, which can realize a narrow frame and ultra-thin design while ensuring the structural strength of the product.

[0013] The backlight module structure of the present invention, such as figure 1 As shown, it includes a display panel 10, an optical film 20, a light guide plate 30, and a reflective sheet 40 stacked up and down, as well as a light-shielding glue 50 and an iron frame 60 arranged on the bottom side of the display panel. Wherein, the optical film is formed by stacking three light-transmitting films.

[0014] Wherein, the side portion 32 of the light guide plate 30 extends upward through the side wall of the optical film 20 and is connected to the display panel 10 through the light-shielding glue 50; the bottom of the light guide plate 30 is provided for assembling the reflective sheet 40 的槽31。 The groove 31. In this embodiment, the reflective sheet 40 is adhered to the groove 31 by glue. Of course, in ...

Abstract

The invention relates to the technical field of display devices, in particular to a backlight module structure. The backlight module structure comprises a display panel, an optical film, a light guide plate and a reflector plate which are stacked in the vertical direction, as well as shading glue arranged at the bottom side of the display panel, wherein the side part of the light guide plate extends upwards through the optical film and is connected with the display panel by virtue of the shading glue; the bottom of the light guide plate is provided with a groove for assembling the reflector plate; the backlight module structure also comprises an iron frame provided with a first end part and a second end part; the first end part is connected with the display panel by virtue of the shading glue; the second end part extends into the light guide plate. According to the backlight module structure provided by the invention, a scheme that the iron frame and the light guide plate are integrated is adopted, the structure with the glue frame at the side part and the iron frame at the bottom in a backlight module is omitted, and a reflecting film is arranged at the groove formed in the bottom of the light guide plate, so that the backlight module structure is relatively narrow and thin.

Description

Technical field [0001] The invention relates to the technical field of displays, in particular to a backlight module. Background technique [0002] The existing backlight module products have narrower frame designs and smaller thicknesses; however, the structural strength of such narrow frame and ultra-thin backlight modules is difficult to guarantee, which may easily cause problems such as loosening and damage of the device. It is difficult to guarantee the quality of the product. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a backlight module structure, which includes a display panel, an optical film, a light guide plate and a reflective sheet stacked up and down, and a light-shielding glue arranged on the bottom side of the display panel; [0004] The side of the light guide plate extends upward through the optical film and is connected to the display panel through the light-shielding glue; the bottom of...
