The best known devices of these types are the LDR (light dependent resistor), the photodiode, the phototransistor, and the PIR (passive infrared) detector. LDR operation relies on the fact that the conductive resistance of a...See more on nutsvolts RSC Publishing
Light sensing in photosensitive, flexible n-type organic thin-film
Considerable interest has been focused on developing a flexible in-cell remote touch screen that should comprise photosensitive OTFTs and switch OTFTs simultaneously. In this work, both switch-OTFTs
