A fluorescent light source (FLS) addressed by a CMOS polysilicon thin-film transistor (poly-Si TFT) driver has been fabricated for the first time. The FLS has 800 pixels with a 200 dpi resolution. 5000 IL brightness has been achieved with only 40 V driving voltage because of driving each pixel in static mode. The FLS feasibility has been confinned by a print head utilized the FLS. The poly-Si TFT driver has been fabricated by a low-temperature process under 600°C, utilizing excimer-laser-annealing. This enables the use of low cost glass substrates and allows integrating the driver within the FLS. Therefore, this technology presents compact and low cost print heads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
