Abstract: According to an aspect, a display apparatus includes: a signal line or a scanning line coupled to a plurality of pixels arranged in a display region; a driver that supplies a drive signal via a resistor to the signal line or the scanning line; and an anomaly detector that monitors a response characteristic of a node between the resistor and the signal line or a node between the resistor and the scanning line.

Abstract: A method of terminating a pair of transmission lines is changed over by terminal setting. Display data is supplied to a master drive circuit and (n−1)-pieces of drive circuits from a host computer via the pair of transmission lines in accordance with a differential serial transmission system. Each drive circuit includes an SELC terminal. When a voltage inputted to the SELC terminal is at a first voltage level, a resistor having a resistance value of Ra is connected between the pair of transmission lines in the master drive circuit thus terminating the pair of transmission lines, and the pair of transmission lines in the slave drive circuits is opened. When the voltage inputted to the SELC terminal is at a second voltage level which differs from the first voltage level, a resistor having a resistance value of (n×Ra) is connected between the pair of transmission lines.
