Timing controller, source driving device, panel driving device, display device and driving method for reducing power consumption through reducing standby durations

摘要

A source driving device, capable of reducing stand-by period and saving power consumption, includes a plurality of source drivers connected in series, which include one or more cascade source drivers. The one or more cascade source drivers include one or more first-type cascade source drivers, each of which, at different times to other first-type cascade source drivers, is respectively activated by a pulse signal generated by a previous source driver, and after the activation, is triggered by a frame signal to receive corresponding frame data in the frame signal. Each of the source drivers generates a pulse signal after receiving the corresponding frame data to activate the next source driver.

1. A source driving device comprising:
a plurality of source drivers, connected in series, comprising:
one or more cascade source drivers, comprising one or more first-type cascade source drivers, each first-type cascade source driver, at different times from other first-type cascade source drivers, activated from power-off to power-up to enter a standby state by a pulse signal generated by a previous source driver respectively, and triggered by a frame signal to receive corresponding frame data from the frame signal after the activation; wherein each of the source drivers other than the last source driver, after complete of receiving the corresponding frame data, generates a pulse signal to activate the next source driver.
