The display substrate includes a base substrate (101) including a display area (AA) and a peripheral area (BB) on at least one side of the display area (AA); and an infrared sensor (102) on the base substrate (101). The infrared sensor (102) is integrated in the peripheral area (BB). The infrared sensor (102) includes a first electrode (1021), a photoelectric conversion function layer (1022) and a second electrode (1023) that are arranged in a stacked manner. The first electrode (1021) is arranged adjacent to the base substrate (101), the second electrode (1023) is made of a transparent conductive material, and the infrared sensor (102) collects infrared rays reflected by an eye from a side where the second electrode (1023) is located.
