Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a bottom plate, a side frame and a light guide plate, wherein the bottom plate and the side frame form an accommodating space, the light guide plate is arranged in the accommodating space and comprises a corner part positioned in a corner area of the light guide plate, and at least one buffer structureis arranged between the corner part and the side frame. The buffer structure can reduce the relative displacement generated between the light guide plate and a metal frame when the light guide plate is impacted, thereby reducing the impact force of the light guide plate on a light bar and the force of the light guide plate driving the light bar circuit board bonded on the light guide plate to move, reducing the shearing force to which the lamp strip circuit board is subjected, and reducing the risk of tearing of the light bar. Therefore, the backlight module and the display device can improvethe reliability of the backlight module and the display effect of the display device.

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] A liquid crystal display device is a flat panel display device. Its working principle is to use the liquid crystal material to modulate light under the action of an electric field to produce various light and dark changes to form images. Since the liquid crystal material itself does not emit light, all liquid crystal display devices require a special backlight module. [0003] The backlight module is one of the key components of the liquid crystal display device. The main function of the backlight module is to provide uniform and high-brightness backlight for the liquid crystal display panel. The basic principle of the backlight module is to convert the commonly used point or line illuminants into surface illuminants with high brightness and uniform gray scale through effective light mechanism, so that the l...
