AI Technical Summary

Problems solved by technology

When assembling the front cover, its ribs will press against the front frame of the backlight module, and the front frame will be deformed and then squeeze the COF, which is very likely to cause the driver chip to collide with the backplane, resulting in abnormal signals
On the other hand, the COF position is often touched during manual operation, causing the driver chip to collide with the backplane, resulting in abnormal signals

Abstract

The present invention provides a backlight module, comprising a front frame, a backplane and a plastic frame located at the edge of the backplane, wherein the printed circuit board of the backlight module is electrically connected to a source driver chip via a COF material, The front frame has a protruding part corresponding to the position of the COF material, and the plastic frame has a groove-shaped part, and the groove-shaped part accommodates the protruding part, so as to enhance the bending resistance of the front frame. With the backlight module of the present invention, a protrusion is provided on the front frame at a position corresponding to the COF material, and a groove is provided on the plastic frame, so that the groove accommodates the protrusion and increases the front frame. of bending strength. In addition, a bent portion can also be provided on the front frame, so as to further improve the bending resistance of the front frame through the bent portion.

Description

technical field [0001] The invention relates to a backlight module, in particular to the structural design of the front frame and the plastic frame of the backlight module. Background technique [0002] With the rapid development of semiconductor technology, especially liquid crystal display technology, liquid crystal displays with small size, light weight and large viewing area are more and more favored by users. At the same time, the reliability requirements for backlight modules in liquid crystal displays are also increasing Getting stricter. In the existing backlight module, it mainly includes a front frame, a back plate and a plastic frame located at the edge of the back plate. The plastic frame and the back plate are designed separately, and a buckle structure is arranged on each of them. Use this buckle structure to combine the backplane and the plastic frame together. [0003] In addition, the printed circuit board in the backlight module is usually arranged behind...
