Problems solved by technology
[0004] However, the above two methods have the following problems. For the above first method, in order to ensure the stability of the electrostatic protection structure, spraying conductive glue will increase the width of the black border of the screen; at the same time, this grounding method may cause poor grounding. The risk of Radiated Spurious Emission (RSE) to the antenna affects the performance of the antenna; for the second method mentioned above, since the gap between the electrostatic protection structure and the metal shell will increase with the folding process of the flexible screen The deformation of the flexible screen changes during the process, and the risk of secondary discharge will occur due to the change of the gap

The invention discloses an electrostatic protection structure and electronic equipment. One end of the metal retaining wall is connected with the metal shell, the other end of the metal retaining wall extends in the direction away from the metal shell, an end face is formed at the end away from the metal shell, and the screen module is arranged on one side of the metal retaining wall; the insulating frame comprises a first side edge, a connecting part and a second side edge; the first side edge is arranged on one side, back to the screen module, of the metal retaining wall; the connecting part is arranged at one end, far away from the metal shell, of the first side edge, the connecting part comprises a butt joint surface attached to the end surface and a first surface facing the screen module, and an insulating layer is arranged between the butt joint surface and the end surface; the second side edge is arranged on one side, facing the screen module, of the connecting part, and the second side edge comprises a second surface facing the screen module; and the butt joint surface, the first surface and the second surface are provided with continuous conductive layers. According to the electrostatic protection structure, the problem that the performance of the antenna is affected by the RSE risk possibly caused by poor grounding and the secondary discharge risk are avoided.
Description
technical field [0001] The present application relates to the technical field of electrostatic protection, in particular to an electrostatic protection structure and electronic equipment. Background technique [0002] In electronic devices such as mobile phones, there will be electrostatic problems on the side of the screen module. Electro-static discharge may cause frequent crashes, automatic shutdowns, poor picture quality and volume, and time difference between good and bad signals. Therefore, Electro-Static discharge (ESD) ) has become an important content of electronic product quality control. Compared with traditional screens, flexible screens are more flexible and bendable, and provide users with a new interaction method based on bendable characteristics, which can meet more needs of users for electronic devices. Since the flexible screen will be deformed during the folding process, the design of the electrostatic protection structure on the side of the flexible scre...
