Abstract

The invention discloses a backlight module and a display device, which relate to the field of display technology and include: a backplane, including a base and an extension connected to the base, where the plane where the base is located intersects with the plane where the extension is located, and the base and the extension form a container The substrate is located in the accommodating space and is arranged on the side of the substrate close to the light emitting surface of the backlight module; the electromagnetic shielding layer is arranged on the side of the substrate away from the substrate; the driving function layer is located on the electromagnetic shielding layer away from the substrate One side of the bottom; a plurality of LEDs are electrically connected to the driving function layer and arranged on the side of the driving function layer away from the substrate. By introducing the electromagnetic shielding layer, the influence of external electromagnetic signals on the driving function layer can be effectively shielded, which is beneficial to improving the display brightness uniformity of the LED and improving the display effect of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a backlight module and a display device. Background technique [0002] As an important part of the liquid crystal display, the backlight module usually uses a light emitting diode (Light Emitting Diode, LED) as the light source, and the backlight module using the LED light source has a relatively thin thickness, which can effectively reduce the thickness of the entire liquid crystal display. The backlight module also has lower energy consumption, therefore, the backlight module using LED as the light source has been widely used. [0003] At present, the penetration rate of LED as a backlight in the field of liquid crystal panel display has exceeded 90%. The backlight module structure mainly has two types: side-type and direct-type. The side-type LED backlight module installs the LED light source on the side of the light guide plate. After the light emitted by t...
