Abstract
A pixel circuit and a driving method thereof and a display device. The pixel circuit includes: a first reverse bias unit, and a first sub-pixel circuit and a second sub-pixel circuit adjacent to each other. The first sub-pixel circuit includes a first light-emitting unit; the second sub-pixel circuit includes a second light-emitting unit. The first light-emitting unit is connected with a first drive node and a second bias output node; the second light-emitting unit is connected with a second drive node and a first bias output node; the first reverse bias unit is connected with the first drive node, the second drive node, the second bias output node, the first bias output node, a first bias control terminal and a second bias control terminal.
