1. An array substrate comprising:
a display area comprising a plurality of pixels coupled to a plurality of gate lines and a plurality of data lines; a data driving unit, coupled to a fan-out unit and configured to drive the data lines; a first switching circuit between the display area and the data driving unit and configured to skip a laser trimming process in an inspection mode, and configured to control the data lines to share electric charges in an image display mode; and a second switching circuit coupled to the fan-out unit via a fuse unit and configured to deliver an inspection signal to each of the pixels through the data lines in the inspection mode, and configured to be disconnected from the fan-out unit in the image display mode, the fan-out unit being between the first switching circuit and the second switching circuit, the fan-out unit being between the first switching circuit and the data driving unit, and the fan-out unit including a plurality of fan-out lines each having a first end connected to each of the data lines and a second end connected to each fuse of a plurality of fuses in the fuse unit in the inspection mode, and connected to data driving unit in the image display mode, wherein the first switching circuit comprises a plurality of pre-charge sharing (PCS) switches comprising alternately arranged first switches and second switches, such that each first switch is adjacent one or more second switches, and such that each second switch is adjacent one or more first switches, each of the PCS switches having a control terminal coupled to a first control line, wherein the first switches have a second terminal coupled to a first sharing line and a first terminal coupled to an odd data line of the data lines, wherein the second switches have a second terminal coupled to a second sharing line and a first terminal coupled to an even data line of the data lines, and wherein the first switches are configured to be operated independently from the second switches.
