Abstract

The invention provides a rubber frame. The rubber frame is used for fixing a backlight module for generating a light source and transmitting the light source to a panel, and comprises an end face for sticking a shading adhesive tape, wherein the end face is provided with an elastic bump. The elastic bump is arranged on the end face of the shading adhesive tape of the rubber frame, and can play a role in damping and buffering when a liquid crystal panel is pressed down, so that an upper prismatic lens, a lower prismatic lens, a diffuser or a light guide plate can be prevented from being damaged by pressing or scratching. The invention further provides a backlight module and a display device.

Description

technical field [0001] The invention relates to the field of electronic display equipment, in particular to a plastic frame, a backlight module and a display device. Background technique [0002] The backlight module is used to provide backlight for the display module in the display device. As the resolution requirements for small-sized liquid crystal displays are getting higher and higher, the brightness requirements of the backlight are gradually increasing. Therefore, it is necessary to highlight the components of the backlight module Treatment, which requires the use of colloids with high hardness or no surface coating, so that the scratch resistance and other properties of the high-gloss treated film will be reduced. When human hands are rubbing or pressing the display screen and performing reliability tests, the display screen will sink to the upper and lower prism sheets, and the upper and lower prism sheets will crush the diffusion sheet, and then damage the light gu...
