Title:
VOLTAGE SAMPLING CIRCUIT, METHOD, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/114291
Kind Code:
A1
Abstract:
A sampling circuit (10) for voltage compensation in a display apparatus. The sampling circuit (10) includes multiple sampling sub-circuits (101). Each of the multiple sampling sub-circuits (101) includes an output terminal (OUT) coupled to a voltage collection port (J), a control terminal (CON) coupled to at least one gate-driving output terminal (D) of a gate-driver-on-array (GOA) circuit (01) for driving the display apparatus, and an input terminal (IN) coupled separately to a respective one of a plurality of voltage sampling points (P) in the display apparatus. Each sampling sub-circuit (101) is configured to collect a voltage signal at the input terminal (IN) and transfer the voltage signal via the output terminal (OUT) to the voltage collection port (J) when the gate-driving output terminal (D) outputs a gate-driving signal.
