    Abstract: A display driving circuit includes N levels of display driving sub-circuits and N levels of switching sub-circuits. Each display driving sub-circuit is connected to a corresponding switching sub-circuit. An nth-level display driving sub-circuit includes an nth-level gate driving sub-circuit and an nth-level light-emitting control sub-circuit. An nth-level switching sub-circuit includes an nth-level gate driving switching sub-circuit and an nth-level light-emitting control switching sub-circuit. The nth-level gate driving switching sub-circuit is configured to enable an nth-level gate driving signal output end to be electrically connected to a (2n−1)th gate line or a 2nth gate line. The nth-level light-emitting control switching sub-circuit is configured to enable an nth-level light-emitting control signal output end to be electrically connected to a (2n−1)th light-emitting control line or a 2nth light-emitting control line, where N is an integer greater than 1, and n is a positive integer smaller than or equal to N.
