Abstract: A chip structure includes a chip wafer unit and a color conversion substrate unit disposed on a light-exit side of the chip wafer unit. The chip wafer unit includes a light-emitting layer and an electrode layer sequentially stacked in a first direction. The light-emitting layer includes light-emitting portions. Each light-emitting portion includes at least two light-emitting sub-portions. The electrode layer includes a cathode, connection electrodes, and anodes in one-to-one correspondence with the light-emitting portions. The at least two light-emitting sub-portions are sequentially connected through at least one connection electrode. Among the at least two light-emitting sub-portions sequentially connected, a first one light-emitting sub-portion is a first selected light-emitting sub-portion, and a last one light-emitting sub-portion is a second selected light-emitting sub-portion. The first selected light-emitting sub-portion is connected to the cathode, and the second selected light-emitting sub-portion is connected to an anode.
