Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a structure capable of fixing an FPC in a casing without being easily displaced. Background Art

[0002] Due to the characteristics of bright display effect, high contrast ratio and small screen size of AMOLED, it is widely applied to smart watches and various equipment projects. The usage environments of some equipment are relatively complex and usually vibrate all the time, so the requirements for fixing each functional component are relatively high. Due to cost reasons, ZIF connectors will be preferentially considered first. The ZIF connectors are very likely to become loose when the equipment vibrates, which will cause various defects during the use of the equipment, thus affecting the consumer experience of the product.
