Abstract
An optical sensor includes: a photosensitive layer that absorbs incident light to generate a first carrier with a first polarity and a second carrier with a second polarity different from the first polarity; a channel layer that is electrically connected to the photosensitive layer and that conducts the first carrier that has moved from the photosensitive layer; a counter electrode facing the channel layer through the photosensitive layer; an insulating layer positioned between the photosensitive layer and the counter electrode; and a source electrode and a drain electrode each electrically connected to the channel layer.
Claims11
An optical sensor comprising:
- a photosensitive layer that absorbs incident light to generate a first carrier with a first polarity and a second carrier with a second polarity different from the first polarity;
- at least two channel layers that are electrically connected to the photosensitive layer and that conduct the first carrier that has moved from the photosensitive layer, the at least two channel layers being electrically insulated from each other;
- a counter electrode facing the at least two channel layers through the photosensitive layer;
- an insulating layer positioned between the photosensitive layer and the counter electrode;
- source electrodes each electrically connected to a corresponding one of the at least two channel layers;
- and
- drain electrodes each electrically connected to a corresponding one of the at least two channel layers.
