Abstract: A fingerprint sensor includes a fingerprint pixel that detects a fingerprint capacitance of a user fingerprint based on a first voltage and outputs fingerprint information corresponding to the detected fingerprint capacitance through a first node. A voltage conversion circuit converts the fingerprint information received through the first node to a signal, which is based on a second voltage lower than the first voltage, and outputs the converted signal. An analog circuit outputs an output signal based on the converted signal by using the second voltage.

Abstract: Disclosed is integrated circuit panel which detects fault of a driving circuit. The integrated circuit panel includes: a driving circuit array including first and second driving circuits; a data driver configured to output first and second input data signals through first and second data lines, respectively; a switch driver configured to output a switching signal through a switch line; and an error detection driver configured to receive first and second output data signals through first and second test lines, respectively, wherein, in response to the switching signal, the first and second driving circuits are configured to output the first and second output data signals, which are based on the first and second input data signal, through the first and second test lines, respectively, and the error detection driver is configured to detect a fault of the first or second driving circuit based on the first or second output data signal.
