The lower diffuser is clamped and fixed between the two groups of limit seats. A first threaded hole is opened at one corner of the surface of the lower diffuser. The first threaded hole is provided in four groups and is symmetrically arranged at the four corners of the surface of the lower diffuser.

[0007] As a further solution of the utility model: the light guide plate includes a prism sheet, a second threaded hole, an upper diffuser sheet and a transparent protective plate. A groove is provided at the top of the prism sheet, and the upper diffuser sheet is fixed in the groove. A second threaded hole is provided at one corner of the surface of the prism sheet. The second threaded holes are provided in four groups and are symmetrically arranged at the four corners of the surface of the prism sheet. A transparent protective plate is placed on the inner wall of the top of the prism sheet.

[0008] As a further solution of the utility model: the first threaded holes of the backlight module correspond to the second threaded holes of the light guide plate one by one, and the corresponding first threaded holes and second threaded holes are internally threadedly connected with fixing bolts.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The backlight module light guide plate comprises a backlight source module and a light guide plate. The top of the backlight source module is fixedly connected to the light guide plate by bolts. When in use, the backlight source module plays the role of light source illumination and has a certain fixing effect, and does not need to use an additional fixing structure for overall fixation.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] See also Figures 1-2 In an embodiment of the utility model, a backlight module light guide plate includes a backlight source module 1 and a light guide plate 2. The top of the backlight source module 1 is fixedly connected to the light guide plate 2 by bolts. When in use, the backlight source module 1 plays the role of light source illumination and has a certain fixing effect, and there is no need to use an additional fixing structure for overall fixation.

[0016] The backlight source module 1 includes a base plate 3, a limiting seat 4, a lower diffuser 5 and a first threaded hole 6. The limiting seat 4 is fixedly connected to one side of the top of the base plate 3. The limiting seat 4 is provided in two groups and is symmetrically arranged on both sides of the top of the base plate 3. The lower diffuser 5 is clamped and fixed between the two groups of limiting seats 4. A first threaded hole 6 is provided in one corner of the surface of the lower diffuser 5. The first threaded hole 6 is provided in four groups and is symmetrically arranged at the four corners of the surface of the lower diffuser 5. A groove is provided inside the base plate 3, and an LED lamp bead for emitting light is fixed in the groove. The light emitted by the LED lamp bead is reflected upward through the lower diffuser 5. The two groups of limiting seats 4 limit the lower diffuser 5 to prevent the lower diffuser 5 from loosening.

[0017] The light guide plate 2 includes a prism sheet 7, a second threaded hole 8, an upper diffuser sheet 9 and a transparent protective plate 10. A groove is provided at the top of the prism sheet 7, and an upper diffuser sheet 9 is fixed in the groove. A second threaded hole 8 is provided at one corner of the surface of the prism sheet 7. Four groups of second threaded holes 8 are provided and symmetrically arranged at the four corners of the surface of the prism sheet 7. A transparent protective plate 10 is placed on the inner wall of the top of the prism sheet 7. The light emitted by the LED lamp beads passes through the lower diffuser sheet 5 and is then reflected twice by the prism sheet 7 and the upper diffuser sheet 9, making the light softer. The transparent protective plate 10 is made of acrylic material, which can play a certain protective role and will not affect the transmission of light.

[0018] The first threaded holes 6 of the backlight source module 1 correspond one to one with the second threaded holes 8 of the light guide plate 2, and the corresponding first threaded holes 6 and second threaded holes 8 are internally threadedly connected with fixing bolts. The backlight source module 1 and the light guide plate 2 fixed with bolts have strong stability and can well ensure the overall integrity.
