The sample-to-answer molecular in vitro diagnostic (IVD) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) includes nucleic acid extractions from saliva, removal of dsDNA and quantitative reverse transcription polymerase chain reaction (RT-PCR). This is critical for display applications where each pixel in the display is controlled by a single thin film transistor (TFT).

Droplets are continually tracked and adjusted through closed-loop feedback enabled by TFT based sensors at each array element. The TFT-DMF array has 41 thousand independently addressable electrodes that are capable of manipulating large numbers of droplets of any size and shape, along any pathway to perform multiple parallel reactions. Operation is based upon the control of injected majority carriers in a wide-band-gap semiconductor by means of an insulated control gate. A thin-film transistors (TFTs) is a special kind of field-effect transistor (FET) fabricated by depositing thin films of an active semiconductor layer, as well as the dielectric layer and metallic contacts over a supporting (but non-conducting) substrate 1,2. for coronavirus disease, COVID-19) at the point-of-need demonstrated. Abstract: A thin-film transistor, TFT, fabricated by evaporation of all components on to an insulating substrate has been developed. This type of display features a TFT for each individual pixel. The latest developments in thin-film-transistor digital-microfluidics (TFT-DMF, also known by the commercial name aQdrop™) are reported, and proof of concept application to molecular diagnostics ( e.g. A thin-film transistor (TFT) is a type of field-effect transistor that is usually used in a liquid crystal display (LCD).
