Backlight module and display device

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a light-emitting element and a light guide plate; multiple light guide slot regions are arranged at one side, close to the light-emitting element, of a reflecting plane of the light guide plate, each light guide slot region comprises multiple light guide slots, and a positive projection of each light guide slot on the reflective plane is arc, and a bending direction of the arc is towards the light-emitting element; a light ray emitted towards an in-light surface of the light guide plate by the light-emitting element is reflected to an out-light surface of the light guide plate through the light guide slots. An angle of departure of the light ray of the light-emitting element after entering the light guide plate can be increased, a dark area and light mixing distance of the light-emitting element are reduced, thereby reducing lower black edge size of the backlight module, and then reducing thelower black edge size of the entire display device, and realizing lower narrow edge design of the display device; furthermore, the thickness of the light guide plate can be reduced on the basis of guaranteeing that all light rays enter the light guide plate, and the thinner and lighter design is realized.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a backlight module and a display device. Background technique [0002] Electronic products such as mobile phones and tablets must not only meet the grip feeling, but also meet the user's needs for screen size. That is to say, it is necessary to make the display area as large as possible within the limited product size, that is, to increase the screen ratio of the product. Therefore, the full-screen design has become a trend in the development of the industry. [0003] like figure 1 Shown is the structural diagram of the display device in the prior art, 1.1 is the upper black border area, 1.2 is the left black border area, 1.3 is the right black border area, 1.4 is the display area, 1.5 is the lower black border area, the current liquid crystal display It is already very difficult to reduce the width of the lower black border area by 1.5. One of the core reasons for limitin...
