1. A display device comprising:
a substrate comprising an active area and a non-active area, wherein the non-active area is located around the active area;
a plurality of display units disposed in the active area of the substrate and arranged in a matrix; and
a plurality of integrated circuits disposed in the active area of the substrate, arranged in a matrix, and electrically coupled to the display units, wherein each of the integrated circuits comprises a shift register unit, each of the shift register units of the integrated circuits is configured to receive a previous-stage scan signal, and generate a current-stage scan signal according to the previous-stage scan signal, and the integrated circuits drive the display units according to the current-stage scan signals;
wherein each of the integrated circuits corresponds to N corresponding display units among the display units, N is an integer greater than 1, and each of the shift register units of the integrated circuits comprises:
a plurality of sub-shift register units electrically coupled in series, wherein the sub-shift register units are denoted as 1st to Nth sub-shift register units, each of the sub-shift register units is configured to delay a previous-stage sub-scan signal to generate a current-stage sub-scan signal, the 1st sub-shift register unit uses the previous-stage scan signal as its previous-stage sub-scan signal, each of the 1st to (N−1)th sub-shift register units transmits the current-stage sub-scan signal to a next sub-shift register unit to serve as the previous-stage sub-scan signal of the next sub-shift register unit, the current-stage sub-scan signal of the Nth sub-shift register unit serves as the current-stage scan signal, and each of the sub-shift register units is configured to generate at least one control signal according to the current-stage sub-scan signal; and
N driving circuits, wherein the driving circuits are configured to drive the corresponding display units according to the control signals.
