Backlight module and manufacturing method thereof as well as display device provided with backlight module

Abstract

The invention discloses a backlight module and a manufacturing method thereof as well as a display device provided with the backlight module. The backlight module comprises a backboard, a light source device, a cable and a line arranger. The light source device comprises a first joint. The cable comprises a second joint connected with the first joint; and the second joint is provided with first and second side surfaces adjacent to each other. The line arranger is rotationally arranged on the backboard, and a rotating shaft of the line arranger is vertical to the backboard; the line arranger comprises a body and a convex part connected with the body; the body is propped against the first side surface; and the line arranger can be rotated to the convex part to prop the second side surface. In the invention, the backlight module and the display device provided with the backlight module can prevent the joints from loosening during the line arrangement. The manufacturing method of the backlight module disclosed by the invention has the foolproof function of preventing poor assembly and wrong assembly sequence and is beneficial to improve the assembly efficiency.

Description

technical field [0001] The present invention relates to a backlight module, its manufacturing method and a display device with the backlight module, in particular to a backlight module with a cable management device, its manufacturing method and a display device with the backlight module. Background technique [0002] With the development of society, liquid crystal display (liquid crystal display, LCD) devices are widely used due to their advantages of thin thickness, low power consumption, and low radiation, such as liquid crystal televisions. The backlight module of a general liquid crystal display device, such as figure 1 The shown backlight module 10 includes a backplane 11 , a cooling plate 12 , a light source device 13 and cables 15 . The light source device 13 is fixed on the cooling plate 12, the light source device has at least one light emitting assembly 131 and a light source circuit board 132, the light emitting assembly 131 can be, for example, a light emitting...

AI Technical Summary

Problems solved by technology

Due to the redundant cable length and messy wiring, it is easy to cause a short circuit and interfere with the assembly of the backlight module. Therefore, the cable 15 needs to be pulled during the cable management process to maintain a certain degree of tension. However, due to excessive force or improper operation, the first The second connector 142 is easily pulled from the first connector 141 by the pulling force of the cable 15, or the first connector 141 is desoldered by the pulling force of the cable 15 and separated from the light source circuit board 132, and finally the light-emitting component 131 cannot be turned on.

Moreover, during the assembly process, the second connector is loosened from the first connector or the first connector is detached from the light source circuit board due to pulling the cable. If the inspection and testing are not carried out in time, the backlight cannot be turned on until the assembly of the backlight module is completed. Then disassembly and reassembly lead to complicated procedures, wasting a lot of manpower and time, and resulting in low production efficiency

[0003] Therefore, in order to solve the problem in the prior art that the backlight cannot be turned on because the second connector is loose or the first connector is detached from the light source device due to cable arrangement, the present invention proposes a backlight module with cable management and positioning connectors As with the display device, the present invention also proposes a method for manufacturing a backlight module with a fool-proof function to prevent errors in assembly procedures or poor assembly
