1. A droplet control and detection device, comprising:

  • a light source;

    a first electrode;

    a second electrode;

    a droplet arranged on a light-exiting side of the light source, wherein the droplet is movable under the effect of an electric field formed between the first electrode and the second electrode;

    a photoelectric detection structure, configured to detect light emitted by the light source and reflected by the droplet; and

    a processing circuit, configured to obtain droplet information according to a detection result of the photoelectric detection structure and control an electrical signal applied on the first electrode and the second electrode according to the droplet information.
