Problems solved by technology
Although this kind of situation increases the assembly space of the lamp tube to a certain extent, in actual use, because the light guide plate 2' can only be arranged along the side of the lamp holder 4', the distance between the light guide plate 2' and the lamp tube is too large. Far, and reduce the use efficiency of the light source

The invention relates to a backlight module comprising a light guide plate, at least one light tube group and at least one group of lamp holders. The light guide plate comprises a first surface, a second surface and an incident surface; the incident surface side is provided with a first bump extending along the first surface; the first bump comprises a third surface and a first side surface; and a nick is formed between the third surface and the incident surface. The light tube group(s) is (are) arranged on the incident surface side; each light tube group comprises a first light tube and a second light tube which are arranged in parallel; the first light tube is arranged in the nick; and the second light tube is adjacent to the first side surface. Each lamp holder comprises a first part and a second part which are connected together and form a first included angle; the end part of the first light tube is arranged in the first part, the end part of the second light tube is arranged in the second part; and the first part leans against the third surface and the second part leans against the first side surface. The invention can provide larger assembly space for the light tubes, thereby preventing the mutual interruption of the light tubes and being capable of increasing the incident surface so as to heighten the brightness.
Description
technical field [0001] The present invention relates to a backlight module, in particular to a backlight module which utilizes a lamp holder to cooperate with a light guide plate to increase the assembly space of the lamp tube and increase the brightness. Background technique [0002] In recent years, liquid crystal display (LCD) devices have been greatly developed due to their advantages of small size, thinness, and low energy consumption. And because the LCD device is a passive electronic display device, it needs a backlight module to provide brightness to display images. The backlight module is divided into direct type and side light type according to the position of the light source. [0003] See Figure 1A and 1B , Figure 1A and 1B Shown is a schematic diagram of an edge-lit backlight module in the prior art. The backlight module 1 includes a light guide plate 2 , lamp sets 3 arranged on both sides of the light guide plate 2 , a lamp holder 4 and a reflector 42 for ...
