Problems solved by technology

In common backlight modules, quantum strips are fixed by plastic brackets, but this structure requires high strength of the backplane, resulting in high cost of the backplane and weak resistance to external forces; in addition, quantum dots are easy to deteriorate under high temperature conditions. Affects the quality, so the temperature near the quantum strip needs to be lowered

Embodiment Construction

[0031] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0032] see figure 2 and image 3 , The present invention provides a backlight module, comprising: a backplane 2 and a light guide plate 4 installed in the backplane 2 , a backlight source 6 , a mounting frame 8 , quantum strips 10 , and a heat insulator 12 . The light guide plate 4 has at least one light emitting surface 42, and the backlight 6 is arranged on the side of the light guide plate 4 corresponding to the light emitting surface 42. In this embodiment, the backlight 6 is located on the side of the light guide plate 4 Installed on the mounting frame 8, the quantum strip 10 is fixedly installed between the light guide plate 4 and the backlight 6 through the mounting frame 8, and the light emitted by the backlight 6 enters the light gu...

Abstract

The invention provides a backlight module. The backlight module comprises a back plate (2), a light guide plate (4), a backlight source (6), a mounting rack (8), a quantum strip (10) and a heat insulator (12), wherein the light guide plate (4), the backlight source (6), the mounting rack (8), the quantum strip (10) and the heat insulator (12) are arranged inside the back plate (2), the quantum strip (10) is fixedly arranged between the light guide plate (4) and the backlight source (6) through the mounting rack (8) which is made of aluminum materials, and the heat insulator (12) is arranged between the quantum strip (10) and the mounting rack (8). Due to the fact that the backlight module is provided with the mounting rack made of the aluminum materials, on one hand, the backlight source is fixed, and the heat dissipation effect is improved; on the other hand, the quantum strip is fixed, the fixing effect is guaranteed, and cost is lowered; meanwhile, the heat insulator is further arranged between the quantum strip and the mounting rack, heat emitted by the backlight source cannot affect the quantum strip, and therefore service life of the backlight module is guaranteed.

Description

technical field [0001] The invention relates to the field of plane display, in particular to a backlight module. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or laptop screens Wait. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. The structure of a traditional liquid crystal panel consists of a color filter substrate (Color Filter), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. Its working principle is to control the rotation of the liquid cry...
