The invention discloses an integrated circuit device, a display panel and a display device. The integrated circuit device includes a first substrate and a plurality of touch signal terminals and a plurality of display signal terminals arranged on the first substrate, and the plurality of touch signal terminals and the plurality of display signal terminals are used for setting with the non-display area of the display substrate The multiple connection signal terminals correspond to the bonding connection, and the integrated circuit device also includes an ultrasonic fingerprint identification device arranged on the first substrate. The integrated circuit device is applied to a display device. The display device has a fingerprint identification function, and its front panel does not need to reserve an opening for the fingerprint identification module as in the prior art, so this solution can increase the screen ratio of the display device; at the same time, due to The signal penetration of the ultrasonic fingerprint identification device is relatively strong, therefore, there is no need to use a protective layer with strict thickness requirements, thereby greatly reducing the production cost of the display device.
Description
technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to an integrated circuit device, a display panel and a display device. Background technique [0002] With the in-depth study of human physiological characteristics in user identification, fingerprint recognition has been widely used in various electronic devices such as smartphones and tablets to simplify the user's tasks in various scenarios such as screen unlocking and transaction payment. operation and contribute to increased safety. [0003] At present, the fingerprint identification technology commonly used in various mobile terminals is capacitive fingerprint identification technology, which manufactures multiple fingerprint electrodes on a silicon substrate, and each fingerprint electrode is used as a plate of the capacitor, and the finger is used as the other electrode of the capacitor. According to the capacitance difference between the ridges and valley...
