Direct type backlight module and its lamp tube fixing device

Abstract

The invention discloses a straight-down type backlight module and its lamp tube fixing device, among them the lamp tube fixing device includes: several fasteners, said fasteners are installed between the bottom of the backlight module and several lamp tubes, and each fastener is equipped with a fastening part to clamp a corresponding tube; and several linking bar structures, each linking bar structure is connected with at least one of the adjacent two fasteners, and each linking bar structure both includes a bendable structure, the bendable structure can bend the linking bar structure along a horizontal direction to adjust the distance between adjacent fasteners. Thereby, the tube fixing device in the invention can fix and clamp said tubes with different distances to meet the requirements of different LCD types and tube assemblage error, so it can increase the assemblage convenience.

Description

technical field [0001] The invention relates to a backlight module and a lamp tube fixing device thereof, in particular to a direct-type backlight module and a lamp tube fixing device thereof, which can facilitate assembly of lamp tubes with different spacings. Background technique [0002] In recent years, Liquid Crystal Display (LCD) has gradually replaced the traditional cathode ray display and has become a mainstream product in the consumer market, which has the advantages of lightness, thinness, high brightness, low power consumption, and no radiation. [0003] However, since the liquid crystal molecules in the liquid crystal display panel do not have luminescent properties, the surface light source required by the liquid crystal panel must be provided through the backlight module to display the picture of the liquid crystal panel. Therefore, the backlight module is an indispensable and important component in the liquid crystal display. [0004] Generally speaking, the...

Problems solved by technology

However, some problems often appear in the above-mentioned traditional lamp fixing device in practical application: for example, although the structure of the integrally formed lamp fixing device can hold multiple lamp tubes at the same time, it can only be applied to certain types of liquid crystal displays with The assembly of multiple lamp tubes arranged at a specific or fixed pitch, and for other types of liquid crystal displays with different lamp tube arrangement pitches, the integrally formed traditional lamp fixing device cannot adjust the distance between every two pairs of fixtures. spacing, and cannot use

In this case, it is necessary to redesign another lamp fixture suitable for the LCD display model and redevelop the mold, which leads to waste of time and cost

[0006] As another example, once there is a manufacturing dimensional error in the integrally formed lamp tube fixing device, the distance between every two pairs of adjacent clamps will be slightly inconsistent and cannot be adjusted separately. At this time, it will not be possible to accurately assemble with all corresponding lamp tubes

[0007] Therefore, there is great inconvenience in the assembly of the traditional lamp fixing device
