Abstract
A pixel driving circuit and a display panel. The pixel driving circuit includes at least one first pixel driving unit and at least one second pixel driving unit. The first pixel driving unit includes a first drive transistor and a first light-emitting element, and the first drive transistor has a first threshold adjustment gate configured to receive a first adjustment signal. The second pixel driving unit includes a second drive transistor and a second light-emitting element, and the second drive transistor has a second threshold adjustment gate configured to receive a second adjustment signal. The first light-emitting element and the second light-emitting element have different light emitting colors, and when the first light-emitting element and the second light-emitting element 10 perform at a target grayscale, the first adjustment signal and the second adjustment signal have different voltage values.
