The factor that signal amplitude has an impact is the other factors such as high-frequency signal interference, at this time, what the first source drive signal received
Data-signal has been not enough to support the normal display of display panel, and therefore, the first source driving chip can be to time schedule controller
The second feedback signal is sent, to indicate that time schedule controller stops sending data-signal, causes data to be believed in order to further analyze
Number amplitude be less than reference signal amplitude factor.Wherein, the amplitude of second feedback signal can according to be actually needed into

Value, when the amplitude for the signal that this has been performed signal compensation operation, which increases multiple, is more than preset multiple value, it may be determined that signal
Compensating operation can not make up the influence that signal attenuation produces signal amplitude, at this time, the first source driving chip can to when
Sequence controller sends the second feedback signal, to indicate that time schedule controller stops sending data-signal, is led in order to further analyze
The amplitude of data-signal is caused less than the factor of the amplitude of reference signal.
Alternatively, the size of the amplitude of data-signal can be indicated by different code values, in data detection signal
Amplitude when whether being less than the amplitude of reference signal, can by data detection signal and the corresponding code value of reference signal respectively,
And both code values are compared realization, and when the amplitude of data-signal is less than the amplitude of reference signal, export error code
Testing result, to indicate that the amplitude of data-signal is less than the amplitude of reference signal.Also, it is less than benchmark in the amplitude of data-signal

When the feedback signal arrived is the first feedback signal, time schedule controller need to perform signal compensation operation to sent data-signal,
And the data-signal to be sent after performing signal compensation operation is sent to source driving chip, wherein, time schedule controller logarithm
It is believed that number compensating operation can be increase data signal amplitude operation；When the feedback signal that time schedule controller receives is the
During two feedback signals, time schedule controller need to stop sending data-signal to the first source driving chip, in order to further analyze
Cause the amplitude of data-signal less than the factor of the amplitude of reference signal；When the feedback signal that time schedule controller receives is the 3rd
During feedback signal, time schedule controller need to send data-signal to be sent, i.e., without performing signal to sent data-signal
