Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device cover window integral type fingerprint sensor module assembly and a fingerprint sensor module assembly light guide. More particularly, the present invention relates to an electronic device cover window integral type fingerprint sensor module having a simple appearance and aesthetically pleasing appearance, And a light guide device and mode for identifying the assembly and the fingerprint sensor module assembly.
BACKGROUND ART [0002] Recently, with the public's attention focused on portable electronic devices including smartphones and tablet PCs, research and development on related technical fields are being actively conducted.
In many cases, a portable electronic device incorporates a touch screen integrated with a display as a display device as one of input devices for receiving a specific command from a user. In addition, portable electronic devices may be equipped with various function keys or soft keys as input devices other than a touch screen.
These function keys or soft keys may act as home keys, for example, to exit a running application and return to the home screen, or to return the user interface to a previous layer, And can operate as a menu key for calling up a write menu. Such a function key or a soft key may be realized by a method of sensing the capacitance of the conductor, a method of sensing the electromagnetic wave of the electromagnetic pen, or a hybrid method in which both methods are implemented, and may be implemented as a physical button.
In recent years, as the use of portable electronic devices has rapidly expanded to services requiring security, there has been an increasing tendency to install biometric sensors having functions of measuring biometric information on portable electronic devices for reasons of high security.
Biometric information includes fingerprints, veins of the hand, voices, irises, and fingerprint sensors are widely used as biometric sensors.
The fingerprint sensor is a sensor for detecting the fingerprint of a human being. By performing a user registration or authentication procedure through a fingerprint sensor, data stored in the portable electronic device can be protected and a security accident can be prevented in advance.
The fingerprint sensor can be manufactured in the form of a module including peripheral parts or structures, and can be effectively integrated in various electronic devices since it can be integrated in a physical function key.
In recent years, a navigation function for performing operations of a pointer, such as a cursor, has been integrated into a fingerprint sensor. The fingerprint sensor of this type is called a biometric track pad (BTP) .
There are capacitive type, optical type, ultrasonic type, thermal type, non-contact type, and so on. However, capacitive type fingerprint sensor which is excellent in sensitivity, robust against external environmental change and excellent in compatibility with portable electronic devices, It is widely used.
