Pixel circuit and driving method therefor, display substrate, and display apparatus
By separating the data writing and threshold voltage compensation processes in OLED display technology and controlling them separately using different scanning signal drive circuits, the problems of difficult data writing and insufficient threshold voltage compensation at high resolution and high frequency are solved, thereby improving display performance and image uniformity.

Abstract
A pixel circuit, comprising: a drive sub-circuit (11), a data writing sub-circuit (13), a compensation sub-circuit (12), a coupling sub-circuit (14) and a first control sub-circuit (15). The coupling sub-circuit (14) is coupled to a first node (N1) and a third node (N3). The first control sub-circuit (15) is configured to write a first reference voltage signal, which is provided by a first reference voltage line (REF1), into the third node (N3) under the control of a first control line (S1) after the data writing sub-circuit (13) writes a data signal to the third node (N3), such that the data signal is coupled to the first node (N1) by means of the coupling sub-circuit (14).
