Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, a backlight module and a display device provided by the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0022] common reference figure 1 and figure 2 , the first embodiment of the backlight module 10 provided by the present invention includes a light guide plate 11 , a light bar 12 and a light-shielding tape 13 .

[0023] The light guide plate 11 includes a light incident surface 111 and three peripheral side surfaces 112 , and also includes a light exit surface 113 and a bottom surface 114 opposite to the light exit surface 113 .

[0024] Wherein, the three peripheral sides 112 are zigzag-shaped, and the size of the light guide plate 11 on the side of the light incident surface 111 is larger than the size of the light guide plate 11 on the side of a peripheral side 112 opposite to the ...

Abstract

The invention provides a backlight module group and a display device, and the backlight module group comprises a light guide plate, a light bar, and a shading adhesive tape. The light guide plate comprises a light incoming plane and three peripheral side surfaces. The light bar is located at one side of the light incoming plane and provides a light source for the light guide plate. The shading adhesive tape wraps the three peripheral side surfaces so as to prevent the light arriving at the light guide plate from coming out of the three peripheral side surfaces. The backlight module group saves an adhesive frame which is set for preventing the light leakage of the three peripheral side surfaces in the prior art under the condition that the three peripheral side surfaces do not allow light to come out, thereby reducing the weight of the backlight module group, reducing the width of the backlight module group, achieving the light and narrow backlight module group, and reducing the production cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] LCD liquid crystal screens are widely used in displays. Since liquid crystal molecules themselves cannot emit light, LCD displays generally have a backlight module that provides a light source for the liquid crystal molecules. [0003] Generally, the backlight module includes a light bar and a light guide plate. The light guide plate includes a light incident surface, three peripheral sides and a light output surface. To provide a light source for the liquid crystal molecules, in the prior art, in order to prevent light from being emitted from the three peripheral sides of the light guide plate, a plastic frame is generally used at the corresponding positions of the three peripheral sides, and the plastic frame can block the light emitted from the three peripheral sides The backlight module will not leak lig...
