Abstract

The invention provides an injection molding equipment, an LCD module, a backlight module and its manufacturing method thereof. The manufacturing method of the backlight module comprises the following steps: an injection molding material of a light guide plate is injected into a drainage groove of a second mold unit. The injection molding material flows through the drainage groove into a corresponding area of a slot of a finished product flexible printed circuit board placed in a first mold unit. After moulding of the injection molding material of the light guide plate, a one-piece part of the light guide plate and the finished product flexible printed circuit board is obtained. An optical film group, the one-piece part of the light guide plate and the finished product flexible printed circuit board and an iron-rubber integrated frame or a rubber frame are assembled. According to the invention, production efficiency and product quality of the backlight module are enhanced.

Description

technical field [0001] The invention relates to the field, in particular to an injection molding device, a liquid crystal module, a backlight module and a manufacturing method thereof. Background technique [0002] With the rapid development of network and radio communication technologies, small and medium-sized products, especially portable information products such as smart terminals, have made great progress. While constantly pursuing high resolution, high contrast ratio, narrow frame and ultra-thin display devices, it is also hoped to reduce their production costs. The components of the backlight module with plastic-iron integrated frame include: plastic-iron integrated frame, reflector, plastic frame, light guide plate, finished flexible circuit board (FPCA) and optical film set. In the prior art, the plastic-iron integrated frame, light guide plate, reflector, and FPCA of the backlight module are injected and molded separately, and then manually assembled and fixed to...
