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 present application shows an electrostatic protection structure and electronic device. One end of the metal retaining wall is connected to the metal shell, the other end extends away from the metal shell, and an end face is formed at one end away from the metal shell, and one side of the metal retaining wall is a screen module; the insulating frame includes a first A side, a connecting portion and a second side; the first side is arranged on the side of the metal retaining wall facing away from the screen module; the connecting portion is arranged at one end of the first side away from the metal shell, and the connecting portion includes and The butt surface with the end surfaces attached, and the first surface facing the screen module, an insulating layer is arranged between the butt surface and the end surface; the second side is arranged on the side of the connecting portion facing the screen module, and the second side includes a The second surface of the screen module; the butt surface, the first surface and the second surface are provided with continuous conductive layers. The electrostatic protection structure of the present application avoids the problem of RSE risk that may be caused by poor grounding, thereby affecting the performance of the antenna, and the risk of secondary discharge.
Description
technical field [0001] The present application relates to the technical field of electrostatic protection, and in particular, to an electrostatic protection structure and electronic equipment. Background technique [0002] In electronic devices such as mobile phones, there will be static electricity problems on the side of the screen module. Electrostatic discharge may cause the mobile phone to frequently freeze, automatically shut down, poor image quality and volume, and time difference between good and bad signals. Therefore, electrostatic protection (Electro-Staticdischarge, ESD) ) has become an important part of the quality control of electronic products. Compared with traditional screens, flexible screens are more flexible and bendable, providing users with a new interaction method based on the bendable characteristics, which can meet more needs of users for electronic devices. Since the flexible screen will deform during the folding process, the design of the electros...
