Description
Technical field
The present invention relates to a kind of backlight module and use its LCD, particularly relate to a kind of backlight module that is provided with tool corresponding to the framework of two line outlets of two ends of a light tube group.
Background technology
Along with LCD (liquid crystal display, LCD) manufacturing technology is progressive fast, with and possess and frivolous, power saving arranged and do not have advantages such as width of cloth ray, make LCD be applied in large quantities personal digital aid (PDA) (personal digital assistant, PDA), in the various electronic product such as mobile computer, digital camera, digital camera camera, mobile phone, computer screen and LCD TV.Add the positive input research and development of industry and adopt the production equipment that maximizes, the quality of LCD is improved constantly, and the lasting decline of price, therefore make the application of LCD enlarge rapidly.But, need could produce the function that shows by the light that backlight module provided because the display panels in the LCD is the display panel of non-self-luminosity.
Please refer to Figure 1A, it illustrates is the exploded view of a traditional backlight module.In Figure 1A, backlight module 10 comprises a glue frame 11 and light tube group 12a and 12b, glue frame 11 comprises relative frame 11a and 11b and relative frame 11c and frame 11d, frame 11a and 11b connect frame 11c and 11d, light tube group 12a has a relative leading-out terminal 13a and a non-leading-out terminal 14a, and leading-out terminal 13a couples by a power lead 15a and a connector 16a.Light tube group 12b has a relative leading-out terminal 13b and a non-leading-out terminal 14b, and leading-out terminal 13b couples by a power lead 15b and a connector 16b.Shown in Figure 1B～1E, because it is other that circuit board and lamp tube driver (inverter) are positioned at frame 11d, have only the design that the corner has line outlet that is connected of the connection corner of frame 11a and 11d and frame 11b and 11d, but the connection corner of frame 11a and 11c and frame 11b and 11c be connected the design that the corner does not have line outlet.The perforation that penetrates light tube group 12a by screw 17a is locked in the vertical type assembling design of the screw hole of frame 11a, light tube group 12a by screw 17a locking on frame 11a.Similarly, the perforation that penetrates light tube group 12b by screw 17b is locked in the vertical type assembling design of the screw hole of frame 11b, and light tube group 12b is locked on the frame 11b by screw 17b.At this moment, power lead 15a and connector 16a will be by frame 11a and 11d the line outlet of connection corner be exposed to outside the glue frame 11, and power lead 15b and connector 16b will be by frame 11b and 11d the line outlet of connection corner be exposed to outside the glue frame 11, connector 16a and 16b will couple by lamp tube driver and circuit board.
Yet above-mentioned fixed lamp tube group 12a and the design of 12b in glue frame 11 must be dependent on screw 17a and 17b, and must perforate on light tube group 12a and 12b and glue frame 11.Thus, cause the mode that is loaded and unloaded on the glue frame 11 of light tube group 12a and 12b comparatively complicated, and the lay time is more tediously long.In addition, when circuit board and lamp tube driver are positioned at the side of frame 11c, because there is line outlet frame 11a and the connection corner of 11d and the corner that is connected of frame 11b and 11d, but the connection corner of frame 11a and 11c does not have line outlet with the corner that is connected of frame 11b and 11c, be that the mode that light tube group 12a and 12b are fixed on the glue frame 11 is unidirectional asymmetry, cause the assembling design of above-mentioned glue frame 11 and light tube group 12a and 12b to be employed.
Please refer to Fig. 2, it illustrates is the exploded view of traditional another backlight module.In Fig. 2, backlight module 20 comprises a glue frame 21 and light tube group 22a and 22b, and glue frame 21 comprises relative frame 21a and 21b and relative frame 21c and frame 21d, and frame 21a and 21b connect frame 21c and 21d.Frame 21a and 21b respectively have a chute, and the opening of this two chute is on frame 21c.Light tube group 22a and 22b have supply coupling end 23a and 23b respectively, and light tube group 22a and 22b are inside and outside slidably debouching the chute of frame 21a and 21b respectively along the direction of arrow.When light tube group 22a and 22b slided in frame 21a and 21b respectively, supply coupling end 23a and 23b were exposed to outside the glue frame 21, and supply coupling end 23a and 23b are in order to couple by other lamp tube driver of frame 21c and circuit board by the frame 21c
Yet above-mentioned light tube group 22a and 22b slide on the design inside and outside the glue frame 21, cause the chute inwall of light tube group 22a and 22b and frame 21a and 21b to produce wear phenomenon easily.In addition, extracting in light tube group 22a and the 22b process inside and outside glue frame 21, the light tube group easy deformation, and then cause the fluorescent tube of light tube group to produce the damage phenomenon.In addition, when circuit board and lamp tube driver are positioned at the side of frame 21d, because the opening of the chute of frame 21a and 21b is on frame 21c, be that the mode that light tube group 22a and 22b are fixed on the glue frame 21 is unidirectional asymmetry, cause the assembling design of above-mentioned glue frame 21 and light tube group 22a and 22b to be employed.
