Embodiment Construction

[0021] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The invention provides a backlight module and a liquid crystal display device. Figure 1 to Figure 5 An embodiment of the backlight module of the present invention is shown.

[0023] like figure 1 As shown, it is a schematic structural diagram of the backlight module of this embodiment, which may include an LED component 1, a quantum dot layer 2, a graphite sheet 3, a reflective sheet 4, a light guide plate 5, etc., wherein the quantum dot layer 2 is arranged on the Between the light guide plate 5 and the LED assembly 1 , the quantum dot layer 2 is disposed on the graphite sheet 3 .

[0024] In this example, if Figures 1 to 4 As shown, the quantum dot layer 2 is engaged and arranged on the graphite sheet 3, specifically, the side of the quantum dot layer 2 in contact with the graphite sheet 3 is provided wi...

Abstract

The invention discloses a backlight module and a liquid crystal display device. The backlight module comprises an LED assembly and a light guide plate and further comprises a quantum dot layer and a graphite sheet, wherein the quantum dot layer is arranged between the LED assembly and the light guide plate; and the quantum dot layer is arranged on the graphite sheet. The quantum dot layer is mounted on the graphite sheet, so the quantum dot layer can be heat-radiated and efficacy loss due to excessive high temperature of the quantum dot layer can be prevented; and service life of the quantum dot layer can be prolonged at certain degree and display quality can be improved.

Description

technical field [0001] The invention relates to the field of display liquid crystals, in particular to a backlight module and a liquid crystal display device. Background technique [0002] Currently, the color gamut level of liquid crystal display devices (including flat panel display devices) is generally around 72%, or even lower. In order to improve the color gamut, quantum dot backlight technology emerged as the times require, which can increase the color gamut of display products to 100%, greatly enriching the performance capabilities of display products. However, some defects of quantum dots limit its application in the field of backlight: First, the heat resistance of quantum dots is poor, and it is easy to age and fail when it reaches a certain temperature, which limits its application directly on LED chips; second, if quantum dots are used The backlight module of the quantum dot glass tube, because the fixing method of the quantum dot glass tube is complicated, and...
