Title:
PATTERNED RESISTANCE DETECTION CIRCUIT AND METHOD FOR DETECTING PATTERNED RESISTANCE OF DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/049230
Kind Code:
A1
Abstract:
A patterned resistance detection circuit according to an aspect of the present invention comprises: a current source generator which generates a reference current and applies same to a patterned resistance; a reference voltage generator which generates a reference voltage by using a plurality of resistors and a plurality of switches; a comparator which compares the magnitude of a detection voltage detected by the reference current applied to the patterned resistance with the magnitude of the reference voltage and outputs a voltage comparison result; and a circuit controller which outputs a reference voltage control signal for controlling the plurality of switches according to the voltage comparison result.
