针对医用单色液晶显示器，提出了一种新的分辨率增强技术--独立亚像素驱动技术。单色液晶显示器的每个像素由三个子像素组成，其中彩色液晶面板去除了彩色滤光片。在新的液晶显示系统中，采用这种新技术，亚像素的强度根据详细的图像信息进行调制，从而提高了三倍的分辨率。因此，新技术实现了15百万像素（MP）的超高分辨率LCD（SHR-LCD），而传统的5 MP LCD和9 MP SHR-LCD则是传统的3 MP LCD。在本研究中进行的物理测量和感知评估证明，实现的15 MP（通过我们的新技术）是适当和有效的，以描绘更精细的解剖结构，如乳腺X射线摄影中的微钙化。
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.
