Abstract
Display panel and display apparatus are provided. Pixel circuit in display panel includes drive transistor, first light-emitting control module, and second light-emitting control module. In first pixel circuit, control terminal of first light-emitting control module receives first control signal, and control terminal of second light-emitting control module receives second control signal. In second pixel circuit, both control terminal of first light-emitting control module and control terminal of second light-emitting control module receive first control signal or receive second control signal. In first mode, first control signal and second control signal are different control signals. In working cycle of first pixel circuit, effective pulse period of first control signal partially overlaps with an effective pulse period of second control signal. The present disclosure can make different light-emitting devices achieve different light-emitting durations, thereby compensating differences of different light-emitting devices in luminous efficiency.
