    摘要： A pixel circuit includes a data writing sub-circuit and a leakage prevention sub-circuit. The data writing sub-circuit is coupled to a first scan signal terminal, a data signal terminal and a light-emitting control sub-circuit, and is configured to: in a data writing period, store a light-emitting compensation signal in response to a gate scan signal from the first scan signal terminal and a data signal from the data signal terminal; and in a light-emitting period, assist in controlling the light-emitting control sub-circuit to be turned on according to the light-emitting compensation signal. The leakage prevention sub-circuit is coupled to the data writing sub-circuit and an auxiliary voltage terminal that is configured to provide to a constant voltage, and is configured to: in the data writing period, store another light-emitting compensation signal; and in the light-emitting period, inhibit leakage of the data writing sub-circuit according to the another light-emitting compensation signal.

    摘要： A pixel structure includes a base substrate and a light emitting element on the base substrate. The light emitting element includes a reflective electrode, a light emitting layer on the reflective electrode, and a substantially transparent electrode on a side of the light emitting layer away from the reflective electrode. The reflective electrode has a reflective ridge configured to reflect light laterally transmitted through the light emitting layer to exit from a light emitting surface of the pixel structure. The reflective ridge has a first concave reflective sidewall extending from a peak of the reflective ridge to a base of the reflective ridge, and a second concave reflective sidewall extending from the peak of the reflective ridge to the base of the reflective ridge. The first concave reflective sidewall faces away from the second concave reflective sidewall.
