摘要： Image signal line driving circuits each include a timing controller that generates a control signal to control the image signal line driving circuit itself and a different image signal line driving circuit. A master belonging to the image signal line driving circuits has a function of applying the control signal to a slave belonging to the image signal line driving circuits. The image signal line driving circuits each include an abnormality detecting circuit that detects an operation abnormality in the image signal line driving circuit itself, and a master/slave switching circuit that sets the image signal line driving circuit itself as the master or slave image signal line driving circuit. When detecting an abnormality, the abnormality detecting circuit outputs a master/slave switching signal, thereby switching the slave image signal line driving circuit to the master and switching the master image signal line driving circuit to the slave.

摘要： An object of the present invention is to provide a driver IC and a liquid crystal display apparatus which uses a circuit of an output channel which is not used to drive a liquid crystal panel as a backup of the other output channel. A driver IC includes a plurality of output channels ch1 to chn, a plurality of output buffer circuits corresponding to each of the plurality of output channels ch1 to chn, and an output channel selection circuit, and when a malfunction occurs in the output buffer circuit of an effective channel, the output buffer circuit in which the malfunction occurs is automatically switched to the output buffer circuit of an ineffective channel so that the output of the signal from the effective channel is continued.

摘要： Each of image-signal-line drive circuits includes a timing controller that generates a control signal controlling itself and other image-signal-line drive circuit, and a master/slave selection circuit that sets itself as a master mode image-signal-line drive circuit or a slave mode image-signal-line drive circuit based on a selection signal to be given from outside. From among the plurality of image-signal-line drive circuits, the master mode image-signal-line drive circuit gives the control signal to the slave mode image-signal-line drive circuit.
