Problems solved by technology

[0003] In the prior art, since the FPC103 is floating on the plastic frame 101, when a slight external force or vibration acts on it, it is easy to make the FPC103 retreat or shift, so that the connection between the FPC103 and the PCB102 is disconnected. like figure 2 shown
As a result, defects such as poor contact are caused to the entire backlight module, which affects the efficacy of the backlight

Abstract

The invention provides a glue frame and a back light module containing the same. In the glue frame and the back light module, a wiring trough is designed to be arranged on the glue frame; the wiring trough is provided with a first wiring trough and a second wiring trough which are respectively used for accommodating the terminal part and the wire part of a flexible circuit board; and simultaneously, the wiring trough is provided with a stop part which has the function of preventing the flexible circuit board from falling off caused by external force or vibration after the flexible circuit is connected correctly.

Description

technical field [0001] The present invention relates to a plastic frame and a backlight module comprising the same. In particular, the present invention relates to a plastic frame which enables a flexible circuit board to be retracted and positioned and a backlight module comprising the same. Background technique [0002] In recent years, flat panel display technology including liquid crystal display technology has been greatly developed, and has gradually replaced cathode ray tube (CRT) display technology. For a liquid crystal display device, since the liquid crystal display panel itself does not emit light, it usually has a display panel and a backlight module for illuminating the display panel. Such as figure 1 Shown is a schematic top view of a prior art backlight module (components such as optical films not mentioned in the present invention are not shown), which includes a plastic frame 101; a printed circuit board arranged on one side of the plastic frame 101 (Print...
