Background

In order to keep privacy when using an electronic device with a screen, such as a notebook computer, a tablet computer, or even an intelligent mobile phone, which uses the screen to display a screen, it is not desirable for nearby people to view the screen displayed by the electronic device, a user of the electronic device usually sets a peep-proof sheet on the screen, so that the screen displayed by the screen can only be seen within a certain angle range, and thus the user can view the screen displayed by the screen under the condition of keeping privacy. In addition, in order to protect the eye health of the user, the screen of the electronic device is also provided with a filter to filter light rays which can cause damage to the eyes.

For ease of use, a privacy sheet or filter is typically positioned over the screen of the electronic device. The positioning manner of the peep-proof sheet or the optical filter is mostly a structure matched with a screen of the electronic device, for example, a screen panel of the electronic device and a frame body for installing the panel often form a step-shaped step difference part, and the peep-proof sheet or the optical filter can be directly placed on the surface of the screen and positioned on the surface of the screen through the step difference part. For an electronic device having no step between the frame and the panel, such as a notebook computer, a tablet computer or a smart phone, the anti-peeping sheet or the optical filter has an attachment for positioning on the screen of the electronic device, and the attachment is usually an adhesive or a magnet. In order to provide some functions, such as functions of dormancy or awakening of a screen, manufacturers of electronic devices may set corresponding magnets in a frame of the screen of the electronic device, so that when the screen is covered or lifted from a host, the magnets of the screen and the magnets of a host shell generate magnetic induction to trigger the functions of dormancy or awakening of the screen, and thus, the peep-proof sheet or the optical filter may be adsorbed on the frame of the screen by using an existing magnet structure in the frame of the screen, and thus, the magnetic poles of the attachment of the peep-proof sheet or the optical filter are set to be opposite to the magnetic poles of the frame of the electronic device, so that the adsorption effect is generated between the magnetic poles, and the peep-proof sheet or the optical filter is positioned in the frame of the electronic device.

When the manufacturer of the electronic device installs the magnets in the frame of the screen, the order of the magnetic poles may be the same model but opposite due to the difference of the manufacturing methods, so that the structure in which the conventional attachment member is fixed to the privacy sheet or the filter body may cause the same magnetic poles to correspond to each other and repel each other due to the opposite magnetic poles of the electronic device, and thus the privacy sheet or the filter cannot be attached to the screen frame of some electronic devices with different magnet configurations.
