Abstract

The invention discloses an LGP (Light Guide Plate), a backlight module and a display device, and relates to the field of a display technology. The LGP comprises a diaphragm limit part and a fixed part, wherein the diaphragm limit part is arranged on an emergent surface of the LGP and is used for limiting an optical diaphragm, and the fixed part is used for fixing the LGP and a plastic frame. Therefore, the LGP is capable of effectively solving the problems of vibration friction and bad white points between the LGP and the optical diaphragm.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, a backlight module and a display device. Background technique [0002] Since a liquid crystal display panel is not a self-luminous display device, a backlight module is usually used as a backlight in an existing liquid crystal display device. The light guide plate (English: light guide plate; abbreviation: LGP) is an important part of the backlight module, which can convert the point light source or line light source provided by the backlight into a surface light source. [0003] The traditional light guide plate is usually a flat plate, and only exists in the backlight module as a pure optical component. The structure of the backlight module in the prior art is as follows figure 1 As shown, the optical film 2 and the light guide plate 1 are separately fixed in the backlight module, wherein the optical film 2 is limited by the stepped structure of the plas...
