Abstract
Driving a light-emitting element by a driver capable of testing at least an open or short condition of the light-emitting element. In particular, a driving signal is generated to drive the light-emitting element. It is evaluated based on the value of the driving signal whether a predetermined condition is reached. If so, a latch signal is output indicating that the testing has finished.
