Abstract

A pixel circuit, a display panel, a display device, and a driving method. The pixel circuit includes a light emitting element, a driving transistor, a light emitting control circuit, a reset circuit, a threshold compensation circuit, a first data write circuit, and an initializing circuit. The reset circuit includes a first transistor, the first data write circuit includes a third transistor, and a channel length-width ratio of the first transistor is greater than a channel length-width ratio of the third transistor.
