Abstract

The present disclosure generally relates to the field of detection technology. A sensor includes a base substrate; a voltage dividing photodiode on the base substrate; and a detecting photodiode on the base substrate. The voltage dividing photodiode may include a first electrode and a second electrode arranged in a stack. The detecting photodiode may include a third electrode and a fourth electrode arranged in a stack. The voltage dividing photodiode is configured to operate substantially permanently in a dark state. The detecting photodiode is configured to operate with a reverse bias applied by the first power terminal and the second power terminal, so as to detect a light intensity.
