Description

  The present invention relates to a touch panel having a fingerprint identification function, and is a touch control device for identifying a fingerprint by aligning a fingerprint identification chip on a touch control panel.

Due to the development of multimedia technology, smart portable electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, personal laptops or pallet terminals or wearable devices are increasingly essential tools for people It has become. However, since these portable electronic devices are characterized by high personality, if these portable electronic devices are lost or stolen, the internal information such as address book, photo data, etc. It will be used by a third party to incur unnecessary losses.

For this reason, this type of product ensures the safety of the user's privacy through certain identity authentication and permission management. The main authentication method currently employed is password protection. When the user inputs an accurate password in advance to the portable electronic device, the user can proceed to the control screen of the portable electronic device. However, the security of password protection is low. This is because passwords are easily leaked or hacked. In addition, if the user forgets the password, it is very troublesome. For this reason, portable electronic devices that employ a fingerprint identification device have been put on the market. Since each person's fingerprints are all different, fingerprints are the only feature, and identity cards that employ fingerprint identification are more secure. Furthermore, the identification method using fingerprint identification is simple and saves the user's memory and password entry.

Current fingerprint identification systems are widely applied on handheld or mobile devices. The most commonly used fingerprint identification device is, for example, fixed on one side of a laptop keyboard, or independently on a fixed position on the back of the handheld action device or on the bottom of the handheld device. The volume of the mobile device cannot be reduced. The known fingerprint identification chip packaging module mainly includes a substrate, a chip, and a module packaging body. The chip is placed on the substrate and electrically connected to the substrate, and the module packaging body covers the surface of the substrate and the chip.
