Problems solved by technology

[0003] The advantage of the above-mentioned lamp tube support frame is that it is very convenient to clamp the lamp tube. However, since the lamp tube 210 is completely surrounded by the lamp tube support frame 220, as Figure 1b As shown, the light at this place will be blocked, and the heat of the lamp tube will be easily taken away, so that when it is lit in the initial stage (about 3 minutes), there will be uneven temperature, so it is easier to produce the lamp support Slightly dark situation at the shelf

Embodiment Construction

[0024] refer to Figure 2a , the backlight module 1 of the present invention includes two lamp tube support frames 10 , a back plate 20 , a plurality of lamp tubes 30 , and two support members 40 . It should be understood that the backlight module 1 also includes other components such as a diffuser plate and an optical film, but since other components such as a diffuser plate and an optical film are the same as those of a known backlight module, their illustrations and related descriptions are omitted here. In addition, the supporting member 40 is the same as the known technology, and it is used to support the two ends of each lamp tube 30 .

[0025] refer to Figure 2b , 3a , and 3b, the lamp tube support frame 10 is used to support a plurality of lamp tubes 30 (in Figure 2a There are four of them), and each lamp support frame 10 includes a base 11, a plurality of supporting parts 12, a plurality of holding parts 13, and two joint assemblies 14, wherein each supporting pa...

Abstract

A backlight module consists of multiple light tubes and a light tube support including multiple supporting components and multiple holding components to hold light tubes on supporting component by two cylinders on holding component. The supporting component can reduce contact area of the supporting component to held light tube for keeping uniform temperature of light tube surface so dark period caused by initial low temperature at supporting place can be greatly improved.

Description

technical field [0001] The invention relates to a backlight module and a lamp tube support frame thereof, in particular to a lamp tube support frame which can reduce the contact area with the held lamp tube. Background technique [0002] In the backlight module of the liquid crystal display, the lamp tube is usually clamped by the lamp tube support frame, refer to Figure 1a and Figure 1b , which shows the backlight module 200 and the lamp tube supporting frame 220 disclosed in Japanese Patent Laid-Open No. 2001-210126. In the backlight module 200 , a plurality of lamp tubes 210 are provided, and besides being held by the lamp tube support frame 220 , both ends are supported by the supporting parts 240 . In addition, the lamp tube supporting frame 220 is disposed on the reflecting plate 230 . [0003] The advantage of the above-mentioned lamp tube support frame is that it is very convenient to clamp the lamp tube. However, since the lamp tube 210 is completely surrounded ...
