Method for manufacturing lamp bar and light guide board integrated structure, as well as mold and backlight module

Abstract

The invention relates to the field of manufacture of backlight modules and discloses a method for manufacturing a lamp bar and light guide board integrated structure. The method comprises the following steps: S1, manufacturing LED lamps and a circuit board, and arranging the LED lamps on the circuit board so as to form a lamp bar; S2, providing a mold for manufacturing the lamp bar and light guide board integrated structure, wherein the mold comprises a female mold and a male mold which are matched with each other; putting the circuit board of the lamp bar manufactured in S1 in a sinking groove of the female mold, and assembling the male mold and the female mold, wherein a cavity of the male mold is matched with the female mold to form mold holes together, and the LED lamps of the lamp bar are embedded in the mold holes; S3, injecting injection molding materials of light guide boards into the mold holes from an injection molding channel of the male mold; and S4, keeping the pressure until the structure is cooled, and demolding to form a finished lamp bar and light guide board integrated structure. The lamp bar and light guide board integrated structure manufactured by adopting the method disclosed by the invention can be used for solving the problem that the process of sticking the lamp bar and the light guide board is complex in assembly of the backlight module. The invention further provides the mold for manufacturing the lamp bar and light guide board integrated structure, and the backlight module.

Description

technical field [0001] The invention relates to the field of backlight module manufacturing, in particular to a method for manufacturing an integral structure of a light bar and a light guide plate, a mold thereof, and a backlight module. Background technique [0002] Such as figure 1 As shown, the backlight module in the prior art includes a backplane 101, a light guide plate 102, a light bar 103, a reflector 104, and an optical film 105, and the reflector 104, the light guide plate 102, and the optical film 105 are sequentially stacked on the backplane. 101 on the front surface, the light bar 103 is disposed on one side of the light guide plate 102 . According to the prior art, in the process of assembling the backlight, the light guide plate 102 needs to be attached to the light bar 103 first, then the reflective sheet 104 is assembled into the back plate 101, and finally the light bar 103 and the light guide plate 102 are integrally assembled. into the backplane. In t...
