1. A pixel unit comprising: N light-emitting devices and a pixel driving chip, wherein
the pixel driving chip includes:
a data signal terminal used to receive a data signal;
a power supply signal terminal used to receive a power supply signal; and
N signal channel terminals that are in one-to-one correspondence with the N light-emitting devices;
wherein a first electrode of a first light-emitting device in the N light-emitting devices is configured to be coupled to the power supply signal terminal, a second electrode of an n-th light-emitting device in the N light-emitting devices is coupled to a first electrode of an (n+1)-th light-emitting device and an n-th signal channel terminal in the N signal channel terminals; N is a positive integer greater than 1, and n is a positive integer greater than or equal to 1 and less than or equal to N.
