Title:
PIXEL DRIVING CIRCUIT, DRIVING METHOD THEREOF, ARRAY SUBSTRATE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/010495
Kind Code:
A1
Abstract:
A pixel driving circuit, a driving method thereof, an array substrate (8), and a display apparatus. The pixel driving circuit comprises a drift suppression unit (1), a data writing unit (2), a compensation unit (3), and a working unit (4). The drift suppression unit (1) receives a reference control signal (G1) and a reference signal (VSTRESS), and is used for outputting the reference signal (VSTRESS) to the compensation unit (3) under the control of the reference control signal (G1) during a drift suppression period (p1) and a reset period (p2). During the drift suppression period (p1), the potential of the reference signal (VSTRESS) is less than 0. The pixel driving circuit is used for driving the working unit (4) to work.
