Problems solved by technology
In the liquid crystal display device, the backlight module box seat is a very important component. In addition to the optical module used to process the light, the general backlight module box seat has the module frame and the illuminant unit. The four frame sides of the general frame Most of them are composed of four frame strips, and the frame is mostly manufactured in large quantities by plastic integral injection molding, but the main disadvantage of this manufacturing method is that an injection molding mold can only manufacture a frame of a predetermined size. For large and small liquid crystal display devices, the manufacturer must set up different molds for each size and specification, which relatively makes the manufacturing cost of the product relatively high, which affects market competitiveness, and because the plastic material is easily deformed, the frame structure is easily deformed during remanufacturing and handling damaged

Embodiment Construction
[0012] As shown in Figures 1 to 3, the preferred embodiment of the backlight module box seat of the present invention is suitable for use with a light emitting unit 8. The light emitting unit 8 includes two upright circuit substrates 81 extending left and right and separated from the front and rear, two respectively A drive circuit board 82 extending upward from the top side of one of the circuit substrates 81, and a plurality of illuminants 83 electrically connected between the circuit substrates 81 at left and right intervals. The illuminants 83 can be lamp tubes or light-emitting diodes. . The backlight module box seat includes a rectangular frame 2 and a back plate 7 covering the frame 2 .
[0013] The frame 2 includes two first frame bars 3 extending back and forth and spaced parallel to each other, two second frame bars 4 straddling the two opposite ends of the first frame bar 3 at intervals front and back, and two oppositely assembled and fixed on the first frame bar. ...

A cassette holder of backlight module is prepared as setting two sets of the first metal frame supports being extended longitudinally and being set in left-right interval way in shell frame, bridging two sets of the second metal frame supports being set in front-back interval way between two opposite ends of the first metal frame support, integrating back light module against top surface of the first metal frame support and top surface of the second metal frame support.
Description
【Technical field】 [0001] The invention relates to a backlight module box seat, in particular to a metal backlight module box seat. 【Background technique】 [0002] With the vigorous development of liquid crystal display devices, liquid crystal display devices have gradually replaced traditional cathode tube televisions or display devices, and have gradually become a necessity in modern life. In the liquid crystal display device, the backlight module box seat is a very important component. In addition to the optical module used to process the light, the general backlight module box seat has the module frame and the illuminant unit. The four frame sides of the general frame Most of them are composed of four frame strips, and the frame is mostly manufactured in large quantities by plastic integral injection molding, but the main disadvantage of this manufacturing method is that an injection molding mold can only manufacture a frame of a predetermined size. For large and small l...
