Problems solved by technology

However, due to the limitation of the gluing process, the glue will have a certain width, resulting in an increase in the protrusion of the flexible circuit board after bending, which in turn increases the overall size of the display panel.
[0003] Therefore, the current method of assembling flexible circuit boards still needs to be improved

Abstract

The invention provides a flexible circuit board, an assembly method thereof and a display device. A bending region is arranged on the flexible circuit board, at least one gap and/or at least one through hole is formed in an edge of the bending region, and the gap and the through hole are used for injecting glue into a gap between the bending region and a workpiece after the flexible circuit boardis bent and the workpiece is fixedly connected. An inventor finds out that the flexible circuit board is simple in structure and is easy to implement, the implementation of a glue injection process isfacilitated by the gap and the through hole, the problem of line breakage after the flexible circuit board is bent can be effectively solved after the glue is injected into the gap, and moreover, theworkpiece containing the flexible circuit board is relatively small in frame size.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a flexible circuit board, an assembly method thereof, and a display device. Background technique [0002] At present, when assembling the display panel, it is mostly necessary to bend the flexible circuit board (FPC) to the back of the display panel and fix it, which easily leads to disconnection of the flexible circuit board. In order to avoid the problem of disconnection after the flexible circuit board is bent, glue can be applied between the flexible circuit board and the edge of the array substrate in the display panel when the flexible circuit board is assembled. However, due to the limitation of the gluing process, the glue will have a certain width, resulting in an increase in the protrusion of the flexible circuit board after bending, thereby increasing the overall size of the display panel. [0003] Therefore, the current method for assembling the flexible ci...
