Lamp tube supporting frame and backlight module

Abstract

The invention relates to a lamp tube supporting frame which comprises a supporting base and at least one clamping arm pair extending upwards from the supporting base. A lamp tube containing space through along the first direction is enclosed between the clamping arm pair, a lamp tube inserting hole is formed between the upper ends of the clamping arm pair, a projection distance of the lamp tube inserting hole on a plane vertical to the first direction is limited to be an anti-jump width and a second direction different from the first direction exists, and a projection distance of the lamp tube inserting hole on a plane vertical to the second direction is limited to be an entry width wider than the anti-jump width. Accordingly, the invention improves the working stability of the lamp tube supporting frame, can effectively prevent the lamp tube from jumping off and decreases the manufacture cost of the lamp tube supporting frame.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal displays, in particular to a lamp tube support frame and a backlight module using the lamp tube support frame. 【Background technique】 [0002] In recent years, with the rapid development of flat panel displays, liquid crystal displays have become the mainstream of flat panel displays. However, since the liquid crystal display panel itself in the liquid crystal display cannot emit light, a backlight module is usually provided on the back of the liquid crystal display panel to provide light source, thereby achieving the display function. As the size of the liquid crystal display increases, the size of the backlight module used in the liquid crystal display increases accordingly. In order to provide sufficient brightness of the light source, the length of the lamp tube in the backlight module must also increase accordingly. However, in a large-size backlight module, an overly long lamp tube is likely...

Problems solved by technology

However, as the size of the clamping arm 12 increases, the elasticity of the clamping arm 12 will also decrease. As a result, the pressure required when the lamp tube is pressed into the receiving space 14 through the lamp tube insertion port 16 is also relatively low. increased, thereby increasing the difficulty of assembling between the lamp tube 18 and the lamp tube support frame 100

In order to reduce the difficulty of assembly, the pair of clamping arms 12 of the lamp tube support frame 100 are usually made of materials with good elasticity, however, this will correspondingly increase the material cost of the lamp tube support frame 100
