Claim 0:
1. A pixel circuit, configured to drive a light-emitting element to emit light, comprising: a current control sub-circuit and a time-length control sub-circuit; wherein
the current control sub-circuit is electrically connected to a current data terminal, a scanning signal terminal, a reset signal terminal, an initial signal terminal, a light-emitting signal terminal, a first power terminal, a first node, and a second node, respectively, and is configured to provide a drive current to the second node under the control of the current data terminal, the scanning signal terminal, the reset signal terminal, the initial signal terminal, the light-emitting signal terminal, the first power terminal, and the first node;
the time-length control sub-circuit is electrically connected to a first control terminal, a second control terminal, a time-length data terminal, a ground terminal, a light-emitting signal terminal, a high-frequency input terminal, and the first node, respectively, and is configured to provide a signal of the light-emitting signal terminal or a signal of the high-frequency input terminal to the first node under the control of the first control terminal, the second control terminal, the time-length data terminal, and the ground terminal;
the light-emitting element is electrically connected to the second node and a second power terminal, respectively; and
the time for the first control terminal to receive a valid level signal is within the time for the reset signal terminal to receive a valid level signal, the time for the second control terminal to receive a valid level signal is within the time for the reset signal terminal to receive the valid level signal, and the time for the first control terminal to receive the valid level signal and the time for the second control terminal to receive the valid level signal do not coincide.
