Problems solved by technology

[0003] The reflective surface of the existing edge-type backlight is a plane mirror, which is directly installed on the plastic frame or the back plate. The process generally adopts the method of manual attachment, and the artificial attachment has the problem of attachment yield, which affects the reflection of LED light. Reduce light extraction efficiency
[0004] In addition, the heat dissipation of the backlight module is also a problem that needs to be continuously improved.

Embodiment Construction

[0022] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail the preferred embodiments of the present invention and the accompanying drawings.

[0023] See figure 1 and figure 2 , The present invention provides a backlight module of a display device, which includes: a back plate 2, a reflective cover 5 arranged on the back plate, a backlight light source 6 arranged on the reflective cover 5, and a reflective plate arranged on the back plate 2. 7. The light guide plate 8 arranged on the reflector 7 and the plastic frame 9 respectively connected to the back plate 2 and the light guide plate 8. The backlight light source 6 in the present invention is an LED light bar, and the light emitted by the backlight light source 6 is reflected The cover 5 reflects into the light guide plate 8 to provide sufficient light for the light guide plate 8.

[0024] The back plate 2 is provided with a bottom surface 22 an...

Abstract

The invention provides a backlight module of a display device, which comprises a back plate, a reflecting cover, a backlight source, a reflecting plate, a light guide plate and a rubber frame. The reflecting cover is arranged on the back plate, the backlight source is disposed on the reflecting cover, the reflecting plate is disposed on the back plate, the light guide plate is disposed on the reflecting plate, the rubber frame is respectively connected with the back plate and the light guide plate, light emitted from the backlight source is reflected by the reflecting cover to enter the light guide plate, the reflecting cover comprises a reflecting portion, an abutting portion and a carrying portion, the abutting portion is connected with the reflecting portion, the carrying portion is connected to the abutting portion, the abutting portion is abutted onto the back plate, the backlight source is mounted on the carrying portion, and the carrying portion is disposed on the back plate. The reflecting cover of the backlight module of the display device replaces a manually attached reflecting surface, the problem of low manual attachment yield is avoided, integrity of reflection of the light of the backlight source is guaranteed, and a thermal conduction effect of the backlight source is improved while luminous efficiency of the light guide plate is further guaranteed.

Description

Technical field [0001] The invention relates to a backlight module of a display device, in particular to a backlight module of a display device that can ensure the integrity of reflected light while improving the heat conduction effect of the backlight light source. Background technique [0002] LED backlight modules are mainly divided into two types according to the position of the light source: direct type and edge type. In the direct type backlight, the light source is located directly under the LCD Panel and illuminates directly. Due to the large number of lamps that can be used, it is easy to obtain high brightness, but due to the high cost, it is generally used for brightness requirements. In the higher TV module; the edge backlight light source is located on the side of the light guide plate, and the light of the measuring light source is introduced into the interior through the light guide plate, and the light is totally reflected by the reflective surface and scattered b...
