Abstract

The invention discloses a backlight module, which comprises a light guide plate, a light tube set, a backboard and a plastic frame. The light guide plate guides the light transmission direction, and makes the light emit from the light emergent surface of the light guide plate; the light tube set is arranged on one side of the light guide plate, and comprises light tubes, light tube shades arranged around the light tubes and rubber sleeves playing roles in fixing and protecting; the backboard is arranged below the light guide plate and the light tube set and is used for fixing the light guide plate; the plastic frame is coated at the periphery of the backlight module, wherein the light tube set and the backboard are arranged outside the backlight module side by side, and the light tube setis fixed on the plastic frame. The backlight module provided by the invention can conveniently detach and replace light tube assemblies, and prolong the service life of the backlight module.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module which is easy to replace a lamp tube. Background technique [0002] Liquid crystal display (LCD) is the most widely used flat-panel display at present. Since the liquid crystal in the LCD panel itself does not have light-emitting characteristics, in order to achieve the display effect, a backlight module is required to provide sufficient brightness for the LCD panel. And evenly distributed surface light source. [0003] Please refer to Fig. 1 and Fig. 2 at the same time. The existing backlight module mainly includes a backplane 6, a plastic frame 1, a lamp group 4, a light guide plate 3, and an optical film 2. Among them, the metal backplane 6 is the basic fixing of the backlight module. structure, which accommodates the lamp tube group 4, the light guide plate 3 and the optical film 2, and the plastic frame 1 is fixed as a whole. The lamp group 4 can be disposed on the ...
