Active-Matrix Liquid-Crystal Displays

Amorphous Silicon Transistors and Photodiodes

“…The threshold voltage increases with time, with a corresponding decrease in the current, but the mobility and other parameters are essentially unchanged. The change in V T depends on gate voltage and time according to the following description [16] :…”

Roll‐up Active‐matrix Displays

“…Active-matrix displays differ from the aforementioned displays in that they have a switch incorporated into each pixel (Tsukada 2000). This removes the limitations encountered in passive matrix displays but requires more sophisticated processing equipment to be used.…”

“…This removes the limitations encountered in passive matrix displays but requires more sophisticated processing equipment to be used. The dominant pixel switch technology is the amorphous silicon thin-film transistor (TFT) on glass (Tsukada 2000), although other technology has also been used (Brody 1996, Kuijk 1991. Currently, rigid active-matrix displays on glass are already widespread although flexible active-matrix displays on plastic substrates are still in the research and development phase.…”

Amorphous Silicon–Based Solar Cells

“…B-doped a-SiC is used extensively as a p-type, window layer [56]. a-SiO and a-SiN are used as insulators in thin-film transistors [57], but are not major components in solar cells.…”
