Embodiment Construction

[0027] The present invention will be further illustrated by the following detailed description and accompanying drawings. It should be noted that the descriptions and drawings are only for making the present invention easier for those skilled in the art, and are not intended to limit the scope of the present invention.

[0028] First please refer to figure 1 . figure 1 It is a schematic diagram of an embodiment of a backlight module for a liquid crystal display device of the present invention, used to illustrate the relative relationship of each component in the backlight module before assembly. The backlight module used for the liquid crystal display device of the present invention includes a holding frame 1 for holding each component, a reflection plate 2 for reflecting light to the light guide plate 3, and a light guide for guiding the light generated by the light generating unit 4. The light guide plate 3 of the display panel, the light generating unit 4 for generating l...

Abstract

In the backlight module used in the liquid crystal display device of the present invention, the two sides of the reflecting plate are bent upwards to cover the light generating unit, so as to achieve the function of the lampshade. The problem of electromagnetic interference is overcome by using the silicone sleeve covered with the metal capable of isolating electromagnetic interference and / or coating or covering any surface of the reflective surface of the reflecting plate with metal capable of isolating electromagnetic interference.

Description

technical field [0001] The invention relates to a backlight module for a liquid crystal display device, in particular to such a backlight module for a liquid crystal display device, that is, it uses a reflector as a lampshade for reflecting light generated by a light generating unit. Background technique [0002] The backlight module used in the existing liquid crystal display generally includes a supporting frame, a light guide plate, a lamp module, a reflection plate arranged under the light guide plate, and several optical films arranged above the light guide plate, For example: diffusion film, light collection film, light enhancement film and prism film, etc. The lamp module generally includes a U-shaped reflector as a lampshade, so as to reflect the light emitted by the lamp into the light guide plate, and thereby guide the light from the lamp to the front liquid crystal display panel. [0003] However, in the existing backlight module, the lamp tube is placed in the U...
