Abstract

The invention discloses a backlight module group and a liquid crystal display. The backlight module group comprises a light guide plate and a light source, wherein the light guide plate comprises a light incidence surface, the light source comprises a light emitting surface, the backlight module group also comprises a first back plate and a second back plate, the first back plate comprises a first back plate body and a first bending part, the second back plate comprises a second back plate body and a second bending part, the first back plate body and the second back plate body are glidingly connected, the light guide plate is fixedly connected onto the first back plate body, the light emitting surface of the light source is pasted on the light incidence surface of the light guide plate, the other side of the light guide plate is near the inner side connected with the second bending part, and when the light guide plate expands through being heated, the expanded light guide plate and the second bending part are in contact to generate the thrust, so the second back plate slides relative to the first back plate.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal display. Background technique [0002] With the continuous development of liquid crystal display technology, the requirements for liquid crystal display functions are also getting higher and higher. [0003] figure 1 It is a partial structure diagram of a backlight module in the prior art, and the backlight module includes a light source 11 , a light guide plate 12 and a backplane 13 . The light source 11 can be a light emitting diode (LED) for emitting light, and the light emitted by the light source 11 enters the light guide plate 12 . Wherein, the coupling efficiency between the light source 11 and the light guide plate 12 is directly related to the light utilization rate of the entire backlight module. [0004] In the prior art, the material of the light guide plate 12 is generally a polymer material such as polymethyl...
