摘要： A display substrate has a display area and a peripheral area around the display area. The display substrate includes a plurality of sub-pixels arranged in an array in the display area, and an interface circuit, at least two serial-to-parallel converters and at least one display driver that are in the peripheral area. The interface circuit is configured to receive target data including a plurality of serial display data. A serial-to-parallel converter in the at least two serial-to-parallel converters is used to convert the plurality of serial display data into parallel display data. The serial-to-parallel converter is electrically connected to one display driver to provide the parallel display data to the display driver. The display driver is used to output display driving signals to a plurality of sub-pixels according to the parallel display data.
