Title:
PIXEL DRIVING CIRCUIT, DRIVING METHOD THEREOF, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/109615
Kind Code:
A1
Abstract:
A pixel driving circuit (100) includes a first electrode, a second electrode, and a third electrode of a driving sub-circuit (150) respectively receives a first voltage signal (Vdd1), is coupled to the light-emission control sub-circuit (120), and to a first electrode of a second storage sub-circuit (140). A first electrode and second electrode of a first storage sub-circuit (130) is coupled to a first node (N1) and receives a second voltage signal (Vdd2) respectively. A second electrode of the second storage sub-circuit (140) is coupled to a second node (N2). A writing-compensation control sub-circuit (110) is coupled to the first node (N1) and the second node (N2), and receives a data signal (Vdata), a gate signal (Vgate), and a third voltage signal (Vdd3). A light-emission control sub-circuit (120) is coupled to the first node (N1), the second node (N2), a second electrode of the driving sub-circuit (150), and the light-emission sub-circuit (160), and receives a light-emission control signal (Vem).
