[0006] However, when the heat sink is used to fix the quantum tube in the above-mentioned prior art 2, since the heat sink is made of metal material, on the one hand, it is easy to cause damage to the quantum tube, and on the other hand, the quantum tube will be directly fixed in the heat sink, and the heat sink The temperature of the components usually reaches above 70 degrees, and the quantum material in the quantum tube is prone to failure at this high temperature for a long time, resulting in the deterioration of the optical effect of the liquid crystal display device
At the same time, in this fixing method, the fixing stability between the plastic frame and the radiator is poor due to the small distance between the fixing fulcrums.

Embodiment Construction
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Given the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] In order to solve the problem of the large width of the frame of the liquid crystal display device caused by the installation structure of the quantum tube in the liquid crystal backlight module of the quantum tube backlight source in the prior art, the basic idea of the embodiment of the present invention is to change the prior art. The quantum tube assembly structure of the middle backlight module adopts a new type of plastic frame. On the ...

The invention discloses a backlight module and a liquid crystal display device, and relates to the technical field of liquid crystal display. The backlight module comprises a rubber frame. The rubber frame comprises first rubber frame bodies on at least one lateral side and second rubber frame bodies on at least two lateral sides, wherein the first rubber frame bodies are formed in a containing cavity of a back board, quantum tubes are arranged in the first rubber frame bodies, each second rubber frame body comprises a side portion and a supporting arm connected with the side portion, each side portion is connected with the outer surface of the corresponding lateral side, and each supporting arm is used for fixing a light conducting plate into the containing cavity. On one hand, optical elements such as the quantum tubes and the light conducting plate are fixed, and on the other hand, the outside part of a rubber frame in the prior art is eliminated, and therefore the aim of narrowing a frame of the liquid crystal display device is achieved.
Description
technical field [0001] The present invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] The liquid crystal display device includes a liquid crystal panel and a backlight module that provides a display backlight to the liquid crystal panel, and the color gamut of the backlight directly determines the color gamut of the liquid crystal display device. The backlight using quantum dot technology is a method to improve the color gamut of the display backlight. For example, quantum dots are encapsulated in glass tubes to form quantum tubes, and the light emitted by the light source in the backlight module passes through the quantum tubes to excite the Quantum dots, resulting in a display backlight with a high light field. [0003] In prior art one, such as figure 1 As shown, the liquid crystal display device 100 includes a backplane 31 , a light guide plate 32 and a backlight 27 disposed in the backp...
