Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display modules, and in particular to a module FPC and a display module for improving the problem of fracture at a height difference. Background Art
[0002] In large-size display modules suitable for devices such as tablet computers, a large steel sheet with a thickness of 0.2mm-0.4mm is usually set on the back of the device area of the module FPC of the display module. In the subsequent production process, the module FPC will be bent and pasted on the iron frame of the backlight module through conductive cloth and double-sided tape. Since there is a height difference between the area where the steel sheet is set and the adjacent area in the module FPC, the FPC areas on both sides of the steel sheet are easily broken by external forces during transportation or assembly, and there is a risk of module scrapping and entire machine scrapping.
[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0006] Furthermore, the width of the bending buffer zone is 5 times the thickness of the reinforcing steel sheet.
[0007] Furthermore, the ratio of the line width to the line spacing of the mesh copper is greater than or equal to 1:10.
[0008] The utility model also provides a display module, including the module FPC which improves the problem of fracture at the height difference.
