Abstract :
A new transient detection circuit against electrical fast transient (EFT) disturbance is proposed for display panel protection. The circuit function to detect positive or negative electrical transients under EFT tests has been investigated in HSPICE simulation and verified in silicon chip. The output of the proposed transient detection circuit can be used as a firmware index to execute system automatic recovery operation. With hardware/firmware co-design, the immunity of display panel against transient disturbance under EFT tests can be significantly improved.
