Provided is a display device including: a display panel; and a driving chip. The display panel includes: sub-pixels including first sub-pixels and second sub-pixels located, each first sub-pixel including a first pixel circuit and a first light-emitting element, and each second sub-pixel including a second light-emitting element. The driving chip includes: a data signal output module electrically connected to the first pixel circuit and configured to output a first data signal to the first pixel circuit, so that the first pixel circuit outputs, in response to the first data signal, a first driving current signal for driving the first light-emitting element to emit light; and a driving current signal output module electrically connected to the second light-emitting element and configured to output a second driving current signal to the second light-emitting element, so that the second light-emitting element emits light in response to the second driving current signal.
