Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] Such as Figure 1 to Figure 4 As shown, the embodiment of the present invention provides a mobile terminal, including a backlight module 10 and a display panel 20;

[0019] Wherein, the backlight module 10 includes:

[0020] A light guide plate 11, the light guide plate 11 includes a light exit surface 111 and a bottom surface 112 opposite to the light exit surface 111, and the light guide plate 11 forms an entrance at a portion corresponding t...

Abstract

The present invention provides a backlight module and a mobile terminal. The backlight module includes a light guide plate, the light guide plate includes a light exit surface and a bottom surface opposite to the light exit surface, and the light guide plate forms a light incident side at a part of the corresponding bottom surface that exceeds the light exit surface. The light-incident side includes a beveled surface between the bottom surface and the light-emitting surface, and a light-incident area formed by the orthographic projection of the beveled surface on the bottom surface; a reflective layer, the reflective layer covers the beveled surface, and the reflective surface of the reflective layer faces The bottom surface is arranged; the light source part, the light source part includes a light-emitting element, the light source part is arranged on the light-incident side, and the light-emitting element is located on the side of the bottom surface, and the light-emitting surface of the light-emitting element is set toward the light-incident area. This can effectively reduce the required installation space of the light-emitting element on the light-incident side of the light guide plate, thereby reducing the width of the black border of the backlight module, thereby increasing the screen-to-body ratio of the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a backlight module and a mobile terminal. Background technique [0002] At present, mobile terminals such as mobile phones include a display area and a black border area. In order to increase the screen-to-body ratio of the mobile terminal to meet user needs, it is generally achieved by reducing the black border area of ​​the mobile terminal. The black border area includes an upper black border area and a lower black border area. Among them, the upper black border area is generally the setting area of ​​the receiver and the camera, and the width of the upper black border area can be reduced by designing the receiver or camera under the screen; the lower black border area includes the backlight module beyond the display area of ​​the display screen. For the display part, under the premise of ensuring the working performance of the display screen, the limit size of the non-d...
