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.
