Problems solved by technology

[0006] However, the design of the above-mentioned lamp tube sets 22a and 22b sliding inside and outside the plastic frame 21 may easily cause wear on the inner walls of the slide grooves of the lamp tube sets 22a and 22b and the frames 21a and 21b
In addition, during the process of extracting the lamp tube groups 22a and 22b inside and outside the plastic frame 21, the lamp tube groups are easily deformed, which in turn causes the lamp tubes of the lamp tube group to be damaged.
In addition, when the circuit board and the lamp driver are located beside the frame 21d, since the openings of the slide grooves of the frames 21a and 21b are on the frame 21c, that is, the lamp groups 22a and 22b are fixed on the plastic frame 21 in a one-way non-directional manner. Symmetry, resulting in the above-mentioned assembly design of the plastic frame 21 and the lamp tube groups 22a and 22b cannot be applied

Embodiment 1

[0031] Please refer to Figure 3A , which shows an exploded view of the backlight module according to Embodiment 1 of the present invention. exist Figure 3A Among them, the backlight module 30 includes a frame 31, a first lamp group 32a and a second lamp group 32b, the first lamp group 32a and the second lamp group 32b can be fixed in the frame 31 to provide the backlight module 30 light needed. The first lamp set 32a has a first end 33a and a second end 34a opposite to each other, and the second lamp set 32b has a third end 33b and a fourth end 34b opposite to each other. In this embodiment, the first end 33a is coupled to a first connector 36a through a first power line 35a, and the third end 33b is coupled to a second connector 36b through a second power line 35b. The first end 33a and the second end 34a respectively have a first notch 45a and a second notch 46a, and the third end 33b and the fourth end 34b respectively have a notch. Two ends or one end of the first la...

Embodiment 2

[0043] Please refer to Figure 4 , which shows an exploded view of the backlight module according to Embodiment 2 of the present invention. The difference between the backlight module 50 of this embodiment and the backlight module 30 of the first embodiment lies in the first lamp group 52 a and the second lamp group 52 b , and the rest of the same constituent elements continue to use reference numerals and will not be repeated. The first lamp set 52a has a first end 53a and a second end 54a opposite to each other. The first end 53a is coupled to a first connector 56a through a first power line 55a. The second lamp set 52b has a third end 53b and a fourth end 54b opposite to each other, and the third end 53b is coupled to a second connector 56b through a second power line 55b. The first end 53a and the second end 54a respectively have a first notch 65a and a second notch 66a, and the third end 53b and the fourth end 54b respectively have a notch.

Abstract

A backlight module, in particular a backlight module applied to a liquid crystal display. The backlight module includes a frame and a lamp group. The frame has a first wire outlet and a second wire outlet, and the lamp tube group has a first end and a second end. When a lamp tube group is placed in the frame, the first end and the second end correspond to the first wire outlet and the second wire outlet respectively.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display using the same, in particular to a backlight module provided with a frame with two outlets corresponding to two ends of a lamp tube group. Background technique [0002] With the rapid progress of liquid crystal display (liquid crystal display, LCD) production technology, and its advantages of lightness, lightness, power saving, and radiation-free, the liquid crystal display is widely used in personal digital assistants (personal digital assistants, PDAs). ), notebook computers, digital cameras, digital video recorders, mobile phones, computer screens and LCD TVs and other electronic products. Coupled with the industry's active investment in research and development and the adoption of large-scale production equipment, the quality of liquid crystal displays has been continuously improved, and the price has been continuously reduced, thus rapidly expanding the application field of l...
