Problems solved by technology
However, in actual use, some connector pads have an asymmetric structure, and it is easy to reverse the connector when the connector is punched, resulting in a short circuit on the flexible circuit board and other problems, resulting in the failure of the display device to work normally.

Embodiment Construction
[0042] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

The invention discloses a flexible circuit board, a manufacturing method thereof and a display module comprising the flexible circuit board, and relates to the technical field of display. The flexiblecircuit board comprises a plurality of electric connection terminals, and the electric connection terminals comprise the first electric connection terminals and the second electric connection terminals. In a first direction, the length of the first electric connection terminals is greater than that of the second electric connection terminals, and the number of the first electric connection terminals in a first area is greater than that of the first electric connection terminals in a second area. The flexible circuit board also comprises fool-proof marks which are positioned in the first areaor the second area, and the orthographic projection of the fool-proof marks on the flexible circuit board does not intersect with the orthographic projection of the electric connection terminals on the flexible circuit board. According to the invention, the fool-proof marks are arranged on the flexible circuit board to identify the manfuacturing direction of a connector, so that the connector direction does not need to be checked manually and repeatedly, the workload of the workers is greatly reduced, the problem of missed checking caused by manual checking is avoided, the problems of short circuit and the like caused by the reverse manfuacturing of the connector are effectively avoided, and the connector manfuacturing efficiency and quality are greatly improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular, to a flexible circuit board, a manufacturing method thereof and a display module comprising the same. Background technique [0002] In the display device, the display module and the components of the main board are connected through a flexible circuit board to achieve relevant electrical performance requirements, and connectors are often used when the flexible circuit board is connected to other components. [0003] With the development of products becoming lighter and thinner, the size of the connector is also gradually reduced. However, due to the relatively high requirements for the insertion accuracy of the connector and the flexible circuit board, most of the existing technologies connect the flexible circuit board with the The connector pads of the connector connection are set to a symmetrical structure, and the direction of the connection does not need to be consi...
