Abstract
The present disclosure discloses a transient overvoltage protection circuit, an array substrate, and a display apparatus, wherein the transient overvoltage protection circuit comprises a transient suppression circuit configured to discharge a transient high voltage in a signal to be processed to obtain a first processed signal; and an isolation circuit having an input terminal electrically coupled to the transient suppression circuit, the isolation circuit being configured to isolate a residual voltage in the first processed signal to obtain a second processed signal.
Claims6
A transient overvoltage protection circuit, comprising:
- a transient suppression circuit configured to discharge a transient high voltage in a signal to be processed to obtain a first processed signal;
- and
- an isolation circuit having an input terminal electrically coupled to the transient suppression circuit, the isolation circuit being configured to isolate a residual voltage in the first processed signal to obtain a second processed signal,
- wherein the isolation circuit comprises a level conversion circuit having an input terminal to input the first processed signal,
- wherein the input terminal and an output terminal of the level conversion circuit adopt independent power supplies and the input terminal has impedance, to isolate the residual voltage in the first processed signal, so as to obtain the second processed signal to be output from the output terminal of the level conversion circuit.
