Description

Attachment device for mobile phone protective film

[0001] The present invention relates to an attachment device for a protective film for a mobile phone, and more specifically, to an attachment device for a protective film for a mobile phone that allows anyone to easily and simply attach a protective film to the screen of a mobile phone without any special attachment technology, and that allows the protective film to be accurately attached to the correct position, thereby preventing fingerprints or foreign substances from getting on the protective film and preventing air bubbles from forming during the attachment process.

[0002] Typically, scratches and other blemishes on a mobile phone's screen reduce the clarity and readability of the screen. Therefore, screen protectors are often applied to protect the screen.

[0003] Applying a screen protector manually to a phone screen is time-consuming, prone to fingerprints and foreign substances, and prone to creating air bubbles between the screen and the screen. Therefore, the process of applying the screen protector is often left to experienced staff. However, even these staff members face the challenge of ensuring a clean application of the screen protector.

[0004] As technologies such as LCD and OLED become widely used, most portable electronic devices released recently, such as personal mobile communication terminals such as cell phones and smartphones, digital cameras, and tablet PCs, are equipped with liquid crystal displays manufactured using LCD or OLED technology.

[0005] If scratches or other flaws occur on the surface of the LCD screen, the transparency of the LCD screen deteriorates, and consequently, the readability of the LCD screen deteriorates.

[0006] In this case, the LCD screen must be replaced, but since the LCD screen is made up of an integrated LCD panel, replacement costs a lot of money.

[0007] Therefore, most users who own portable electronic devices use screen protectors attached to the LCD screens of their portable electronic devices.

[0008] Screen protectors are scratch-resistant, have good transparency, and are inexpensive, making them effective in protecting the LCD screens of portable electronic devices from scratches.

[0009] If the screen protector gets scratched a lot, users can keep the LCD screen clean at a low cost by simply replacing the screen protector.

[0010] Meanwhile, screen protectors are being released with various functions beyond simple screen protection, such as preventing fingerprints from appearing on the LCD screen, eliminating glare from the LCD screen, and narrowing the viewing angle of the LCD screen to protect privacy, and are widely used in various mobile devices.

[0011] Screen protectors are made up of a transparent film with adhesive applied to one side and an adhesive surface protector to protect the adhesive surface, and are sold pre-cut to fit the screen size of each device.

[0012] The user removes the adhesive backing of the screen protector from the edge and attaches the transparent film from the edge of the LCD screen. However, if the attachment point of the transparent film is slightly misaligned at the edge of the screen, the attachment point of the transparent film on the other edge will be significantly misaligned.

[0013] In this case, the transparent film is removed and reattached. During this process, fingerprints or foreign substances such as dust can easily stick to the adhesive surface, which reduces the transparency of the reattached transparent film.

[0014] Therefore, attaching a screen protector is a task that requires skill, and beginners often have difficulty attaching a screen protector to an LCD screen.
