Abstract
A starting signal providing module, a starting signal providing method and a splicing display device are provided. The starting signal providing module comprises a detection circuit, a plurality of signal generating circuits and a plurality of enabling circuits. The signal generating circuit is configured to generate and provide a feedback signal to the detecting circuit when a last-stage scan driving signal output terminal of a scan driving circuit in a corresponding display panel outputs a valid scan driving signal. The detection circuit is configured to provide an enabling control signal to enabling circuits corresponding to at least two signal generating circuits according to the feedback signals from at least two signal generating circuits. The enabling circuit is configured to control a starting signal to be supplied to a scan driving circuit included in a corresponding display panel upon receiving the enabling control signal.
