As, occur that LCD sends digital signal notice digital signal processor 13 after there is blank screen or splashette detecting.Such as,
If normally recognizable waveform 2.8V time width be 5us-10us, the waveform less than 5us be come to a point not can recognize that waveform,
Then digital processing unit 13 judges that the width of control signal waveform that detection module 14 the detects waveform less than 5 millimeters is not known
Not, and generate reparation feedback signal send to repair module 20, repair module 20 can regulate operational amplifier 121 and export
The bias voltage of signal.Specifically, when bias voltage raises, operational amplifier 121 output waveform shape is narrow to width by point
High transformation, when bias voltage reduces, operational amplifier 121 output waveform shape, by wide high to sharp narrow transformation, finally regulates
The state of operational amplifier 121 output waveform needs a balance, such as, identify control signal ripple at digital signal processor 13
Shape neither saturation distortion does not haves again the narrowest but also sharp state.
