Claim 4:
5. The scan-type display apparatus of claim 3, wherein, with respect to each of said scan driving circuits,
the second clamp time segment of each of the clamp time intervals includes a first clamp time slice and a second clamp time slice, and
when the detection signal indicates that at least one of said LEDs connected to said scan line corresponding to said scan driving circuit is short circuited, the clamp signal is at the voltage level corresponding to conduction of said clamp switch during the first clamp time slice of the second clamp time segment of a first one of the clamp time intervals, and is at the voltage level corresponding to non-conduction of said clamp switch during other times of the operation cycle.
