S111, when detecting that the screen driving plate of display screen powers on, start the clock and data recovery electricity to the screen driving plate
The monitoring of the working condition on road.
Specifically, when the screen driving plate of the display screen powers on, a HTPDN signal is generated to mainboard, and be associated with
The HTPDN signals and the clock data recovery circuit, it is extensive to monitor the clock data by detecting the HTPDN signals
The working condition of compound circuit.
S112, when monitoring that the clock data recovery circuit is in normal operating conditions, to the screen driving plate send out
Send clock signal.
When the clock data recovery circuit is in normal operating conditions, the HTPDN signals have corresponding variation, example
Such as, when the clock data recovery circuit works normally, the HTPDN signals will produce a failing edge, detecting
When stating the failing edge of HTPDN signals, start the transmission for the clock signal that the mainboard drives to the screen.
S113, when detecting that the screen driving plate of display screen powers on, start the monitoring to the clock status of the screen driving plate.
A kind of display screen sequential control method that the embodiment of the present invention 2 provides is being obtained such as the advantageous effect of embodiment 1
On the basis of, also before clock signal transmission, the state of clock data recovery circuit is monitored, in the clock data recovery circuit
When normal work, restart the transmission of the clock signal, it is ensured that in subsequent signals transmission, such as shield the transmission of signal
In the process, the sequential of the screen driving plate is consistent with the sequential of other circuits of the display screen, improves the steady of signal transmission
It is qualitative.
