With the described first display signal, then, the multiple sub- startup control signal for starting control signal resets described the
One source driver is closing and second source electrode driver is conducting, is made described in the second source electrode driver received in sequence
Second display data trigger signal and the second display signal.
5. transmission method as claimed in claim 2, it is characterised in that when the command signal is produced by an external pins,
The command signal is the external setting-up signal, and for setting first source electrode driver and second source drive
Device is respectively on and off, to receive the display data of the pair of frequency control.
6. transmission method as claimed in claim 5, it is characterised in that the display data also includes one second control triggering
Signal and one second control signal, and the multiple sub- startup control signal for starting control signal first sets described first
Source electrode driver is conducting and second source electrode driver is closing, makes described in the first source electrode driver received in sequence the
One control trigger signal, first control signal, the first display data trigger signal and the described first display signal, connect
, it is described start control signal the multiple sub- startup control signal reset first source electrode driver for closing institute
It is conducting to state the second source electrode driver, makes described in the second source electrode driver received in sequence the second control trigger signal, described
Second control signal, the second display data trigger signal and the second display signal.
7. transmission method as claimed in claim 5, it is characterised in that first source electrode driver and second source electrode
Driver formation one source driver group, after first source electrode driver has received the first display signal, correspondence is passed
A pulse settings signal is sent to second source electrode driver, to switch second source electrode driver by closing to turn on and connect
Receive the display signal.
8. transmission method as claimed in claim 1, it is characterised in that also comprising using per the exclusive ground of one source driver
Location data, the command signal is transmitted to the multiple source electrode driver with correspondence.
9. transmission method as claimed in claim 1, it is characterised in that the mode of operation of the multiple source electrode driver is basis
Every exclusive address date of one source driver or an external pins are set as a leading pattern or a tandem mode to correspond to,
And the source electrode driver for being set to the leading pattern will be triggered to receive described the by the described first control trigger signal
One control signal and triggered to receive the first display signal by the first display data trigger signal, and be set
By the tandem mode source electrode driver will by one second control trigger signal trigger receive one second control signal with
And triggered to receive the second display signal by the second display data trigger signal.
