Problems solved by technology
[0002] At present, in the traditional capacitive fingerprint identification technology used in display devices, the fingerprint identification circuit includes an operational amplifier, and the structure of the operational amplifier is usually a CMOS structure, that is, the structure of the operational amplifier is composed of NMOS tubes and POMS tubes, and the production process is relatively complicated.
In addition, in order to realize the fingerprint identification function, an additional fingerprint identification chip is usually required, and the fingerprint identification is realized through the fingerprint identification chip and the fingerprint identification circuit, which increases the cost of the display device.
[0003] Therefore, in the display device using the traditional capacitive fingerprint recognition technology, the manufacturing process of the display device is relatively complicated, and the manufacturing cost is relatively high.
