Abstract

The invention provides a backlight module and a display device. The backlight module comprises a rubber frame and a light guiding plate located in the rubber frame. A protruding part and a channelingpart corresponding to the protruding part are formed on the rubber frame, and thus an elastic structure is formed; the protruding part of the elastic structure is used for making contact with the sidewall of the light guiding plate, the protruding part offsets towards one side of the channeling part due to extrusion of the light guiding plate, thus the channeling part deforms, the elastic structure and the light guiding plate are in interference fit, and thus the light guiding plate is fixed into the rubber frame and does not offset. According to the backlight module and the display device, the problems that as for a vehicle-mounted display device, when the backlight module shakes, the light guiding plate impacts the side wall, consequently, abnormal noise is generated, and poor optic iscaused due to bruise of net points of the light guiding plate are solved.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to a backlight module and a display device. Background technique [0002] With the development of display technology, there are more and more applications of vehicle-mounted display modules. Due to the high reliability requirements of vehicle regulations, the structural design requirements for vehicle-mounted displays are also relatively high. [0003] In view of the high reliability requirements of the car regulations, if the light guide plate in the backlight is not limited and fixed, there will be problems such as abnormal sound caused by the light guide plate hitting the side wall when the module is shaken, and optical defects caused by scratches on the light guide plate when shaking. Problem: At this stage, the vehicle-mounted display module usually uses multiple rubber blocks (rubber) to withstand the light guide plate to limit the position. [0004] Due to the rel...
