Title:
OVERCURRENT PROTECTION CIRCUIT, DISPLAY PANEL, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/188175
Kind Code:
A1
Abstract:
An overcurrent protection circuit, the overcurrent protection circuit comprising: a voltage conversion unit (110), a reference voltage generation unit (120), a voltage comparison unit (130), and a switch unit (140); the voltage conversion unit (110) is used for receiving an input voltage and converting the input voltage so as to generate a modulation voltage; the reference voltage generation unit (120) is used for generating a reference voltage which is used for comparison with the modulation voltage; the voltage comparison unit (130) is electrically connected to the voltage conversion unit (110) and the reference voltage generation unit (120), respectively, and is used for comparing the modulation voltage with the reference voltage so as to generate a corresponding control signal; the switch unit (140) is electrically connected to the voltage comparison unit (130) and the voltage conversion unit (110), respectively, and is used for determining, according to the control signal, whether to output the modulation voltage.
