Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some but not all structures related to the present invention are shown in the drawings, and the shapes and sizes of the elements in the drawings do not reflect their true proportions, and the purpose is only to illustrate the present invention. Invention content.

[0031] Exemplary, figure 1 It is a structural schematic diagram of an existing display module, see figure 1 , after bending the flexible circuit board 01, there is a certain distance L' between the side of the flexible circuit board 01 and the side of the display module 02, and this distance can be referred to as the protruding length. By reducing th...

Abstract

The embodiment of the invention discloses a flexible circuit board and an assembling method thereof, a display module and a display device, a first end of the flexible circuit board is used for being in binding connection with a binding area of the display module, and a second end of the flexible circuit board is used for being bent to the back surface of the display module; the flexible circuit board comprises a circuit board and a reinforcing plate; the reinforcing plate comprises a first branch, a second branch and a third branch connecting the first branch and the second branch. The plane where the third branch is located intersects with the plane where the first branch is located and the plane where the second branch is located. A first hollow structure is arranged on the first branch, and a second hollow structure is arranged on the second branch; the circuit board penetrates through the first hollow structure and the second hollow structure, and when the flexible circuit board is assembled on the display module, the third branch of the reinforcing plate is located on the side, away from the display module, of the circuit board. According to the technical scheme provided by the embodiment of the invention, the extension length of the flexible circuit board can be reduced to realize a narrow frame, and the circuit on the flexible circuit board is prevented from being broken.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a flexible circuit board and an assembly method thereof, a display module and a display device. Background technique [0002] In the field of display technology, in order to improve user experience, display modules are developing towards the trend of narrow borders and high screen-to-body ratio. [0003] In the prior art, the width of the lower frame is reduced by bending the flexible circuit board of the lower frame to the back of the display module. However, how to reduce the width of the frame as much as possible and at the same time avoid disconnection of the lines on the flexible circuit board is a problem that still needs to be solved. Contents of the invention [0004] Embodiments of the present invention provide a flexible circuit board and its assembly method, a display module, and a display device, so as to avoid disconnection of lines on t...
