Title:
SAMPLING CIRCUIT AND DRIVING METHOD THEREFOR, PIXEL SAMPLING CIRCUIT, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/237111
Kind Code:
A1
Abstract:
A sampling circuit, comprising a first input end, a second input end, a first voltage collection sub-circuit and a current integral sub-circuit. The first voltage collection sub-circuit is coupled to the first input end and the current integral sub-circuit, and same is configured to collect a first voltage at the first input end and transmit the first voltage to the current integral sub-circuit. The current integral sub-circuit is further coupled to the second input end, and same is configured to generate and output a second voltage according to the first voltage and a time integral of a driving current, which is transmitted from the second input end to the current integral sub-circuit, and output the first voltage in response to an integral control signal.
