  • Abstract
    A new resolution enhancement technology using the independent sub-pixel driving technology was developed for the medical monochrome liquid crystal displays (LCDs). Each pixel of monochrome LCDs, which employ the color liquid crystal panels that its color filters are removed, consists of three sub-pixels. In the new LCD system implemented with this new technology, the sub-pixel intensities were modulated according to the detailed image information, and consequently resolution was enhanced three times. Thus the new technology realized a 15 mega-pixels (MP) super high-resolution LCD (SHR-LCD) out of a conventional 5 MP LCD and a 9 MP SHR-LCD out of a conventional 3 MP LCD. Physical measurements and perceptual evaluations performed in this study proved that the achieved 15 MP (through our new technology) was appropriate and efficient to depict the finer anatomical structures such as the micro calcifications in mammography.
