Description

Technical field [0001] The present invention relates to fingerprint identification technology, in particular to a fingerprint identification device and electronic equipment containing the same. Background technique [0002] In recent years, with the development of storage technology, electronic devices such as mobile phones and computers store a large amount of personal information and other important data, and their security has become more important. At present, passwords, graphics, and other forms are often used to achieve password protection for their electronic devices, that is, users can set personal password protection by inputting numbers, letters and combinations of passwords in advance, or inputting specific graphics to electronic devices; When using an electronic device, enter these passwords or graphics again, and the electronic device authenticates the legitimacy of the user's identity by comparing with the preset password or graphics, thereby protecting the user's p...

Problems solved by technology

Image feature recognition and laser feature recognition use visible light and laser to extract fingerprint ridge line information respectively, and use algorithms for feature analysis to identify different individuals; both methods require more complex spatial structures such as CCD probes and laser generators. Not suitable for thin and light applications

[0005] However, the structure of the capacitive fingerprint sensor in the prior art is a silicon substrate structure, and its driving electrodes and sensing electrodes are ITO structures, that is, conductive materials are directly coated on the substrate to form conductive patterns, so that the amount of conductive materials used is large. , and easy to wear; in addition, the conductive material used in the prior art is indium tin oxide, and indium in indium tin oxide is a rare metal and expensive
