1. A display module, comprising:
a circuit board;
an integrated chip, electrically connected to the circuit board, wherein the integrated chip comprises a first chiplet and a plurality of display pixel drive circuits integrated into the first chiplet;
a pixel chipset, comprising a plurality of light-emitting chips, wherein at least one pixel chipset is disposed on a surface of a side, of the integrated chip, that is away from the circuit board, wherein a light-emitting chip is disposed on the integrated chip and electrically connected to a display pixel drive circuit of the plurality of display pixel drive circuits in the integrated chip, and wherein the display pixel drive circuit is configured to drive the light-emitting chip to emit light; and
a circuit substrate, electrically connected to the circuit board, wherein two or more display pixel drive circuits of the plurality of display pixel drive circuits are integrated into the circuit substrate, and an area of a vertical projection of the circuit substrate on the circuit board is less than an area of a vertical projection of the integrated chip on the circuit board;
wherein the display module comprises two or more pixel chipsets, wherein a pixel chipset is disposed on a surface of a side of the circuit substrate away from the circuit board; and
wherein the light-emitting chip disposed on the circuit substrate is electrically connected to the display pixel drive circuit in the circuit substrate.
